The Parque Nacional de Doñana is one of Europe's most important wetland reserves and a major site for migrating birds. It is an immense area; the parque itself and surrounding parque natural or Entorno de Doñana (a protected buffer zone) amount to over 1,300 sq km in the provinces of Huelva, Sevilla and Cádiz. It is internationally for recognised for its great ecological wealth. Doñana has become a key centre in the world of conservationism.
Doñana is well known for its enormous variety of bird species, either permanent residents, winter visitors from north and central Europe or summer visitors from Africa, like its numerous types of geese and colourful colonies of flamingo. It has one of the world's largest colonies of Spanish imperial eagles. The park as a whole comprises three distinct kinds of ecosystem: the marismas, the Mediterranean scrublands and the coastal mobile dunes with their beaches.
l
The configuration of the Parque Nacional de Doñana is a result of its past as the delta of the Guadalquivir river, the 'big river', or Wada-I-Kebir, of the Moors. But it is a delta with a difference. Unlike most, the river has only one outlet to the sea, just below Sanlúcar de Barrameda. The rest of what used to be its delta has gradually been blocked off by a huge sandbar that stretches from the mouth of the Río Tinto, near Palos de la Frontera, to the riverbank opposite Sanlúcar, and which the sea winds have gradually formed into high dunes. Behind this natural barrier stretches the marshlands (marismas).
The effect of this extraordinary mélange of land and water was to create an environment shunned by people but ideal for wildlife. As early as the thirteenth century, the kings of Castille set aside a portion of the Doñana as a royal hunting estate; later the dukes of Medina Sidonia made it their private coto too. One of the duchesses of Medina Sidonia, Doná Ana de Silva y Mendoza, indulged her antisocial instincts by building a residence there that was more hermitage than palace. As a result, the entire region came to be known as the 'forest of Doná Ana', or Doñana. In the eighteenth century, Goya is known to have visited the Duchess of Alba at the Palacio de Doñana when she was its proprietress. Subsequently, the land passed through many hands before the official creation of the parque nacional in 1969.
Meanwhile, adjoining areas of wetland were being dramatically reduced. Across the Guadalquivir vast marshes were drained and converted to farmland, until only the protected lands of the Doñana remained intact. For centuries there had been only a vacant spot on the map between Lebrija in the east and Almonte in the north west, but in recent years whole towns and villages have sprung up west of the Guadalquivir, and the resort town of Matalascañas has brought urban sprawl to the south-western edge of the Doñana, a place once occupied by reed-thatched fishermen's huts. The proximity of these settlements has further complicated the work of the park's wildlife guardians. Two of the Doñana's precious lynxes, for example, have been run over by cars on the highway to Matalascañas; cats and dogs straying out of the nearest towns have killed animals in the park, and birds that have overflown the fences have been gunned down by trigger-happy hunters despite stringent conservation laws.
A more permanent threat to the Doñana's ecosystem are the new ricefields and other agricultural projects north of El Rocío, whose run-off waters sluice pesticides into the marismas and the sulphur mines upstream at Aznalcóliar which was effluvium into the river.

Entrance to the park is strictly controlled. You can take half-day trips with official guides or explore the environs of the visitors' centres on foot.
To visit the principal visitors' centre at El Acebuche, take the A483 south of Almonte and about 12km from El Rocío is the signposted turn at Km29 for Centro de Recepción El Acebuche (959 44 87 11), 1½km from the main road. Alternatively, you can drive 3km north of Matalascañas to the turn-off at Km29. The centre has an exhibition about the park, a café and a shop selling maps and books. From the centre is a signposted 5km trail through scrubland and pine trees. Next to the centre is the El Acebuche lagoon, with bird hides, where you can see purple gallinules, among other birds.
From El Acebuche there are four-hour trips into the park run by the Cooperativa Marsimas del Rocío (959 43 04 32), which must be booked in advance. The four-wheel drive vehicle can seat 21 people and guides speak some English. There are two trips a day (excluding Mondays), at 0830 and 1500 (1700 in summer). Full day trips can also be organised for groups, with lunch in Sanlúcar de Barrameda. A typical trip will take in all three ecosystems in the park - dunes, matorral and marshland - but the amount of exposure to each environment varies with the seasons. One thing is guaranteed - no two visits will be alike.
The nearest visitors' centre to El Rocío is La Rocina (959 44 23 40), 500m from the village and just off the Matalascañas road. It has information on the park and a 3km-long nature trail along the freshwater lake and marshland Charco de la Boca, which feeds into the Madres de la Marismas at El Rocío. The trail has five bird hides and it's possible to see purple gallinules, hoopoes, herons and Savi's warblers, among other birds.
Seven kilometres on from La Rocina is the Palacio del Acebrón, an old hunting lodge containing exhibitions on the park. In the grounds is a pleasant 1½-km nature trail through woodland and around a small lake, the Charco del Acebrón.
The Centro de Visitantes José Antonio Valverde on the northern edge of the park has some excellent birdwatching opportunities. It is 30km south of the town of Villamanrique de la Condesa, from where it is signposted.
The Playa de Castilla beach, reached on foot east of Matalascañas, runs alongside the park boundary and although you can't enter Doñana here, it is a beautiful, unspoilt stretch of coastline with good birdwatching possibilities.
The park can also be reached (but not entered) by taking the ferry boat across the Guadalquivir river from Sanlúcar de Barrameda where there is a visitors' centre, the Centro de Visitantes Fábrica de Hielo (956 38 16 35), with exhibitions on the Doñana. You can take the Real Fernando boat daily (except in January) from Sanlúcar for 13km up the Guadalquivir river, stopping in a few places for guided walks into the park. It's advisable to book in advance, especially during the summer and holidays.
Accommodation
The closest accommodation to the entry point of El Acebuche in the park is in Matalascañas, about 3km from El Acebuche. Ten kilometres north of El Acebuche is the village of El Rocío, with various hotels. Alternatively, between Matalascañas and Huelva there is Mazagón or Villamanrique de la Condesa to the north of the park. Accommodation will be very hard to find (or extremely expensive) around the time of the El Rocío pilgrimage at Pentecost. During the summer months Matalascañas and Mazagón are also very busy, so book ahead at this time.
• El Cortijo de los Mimbrales (959 44 22 37) Conveniently located for the park on the A483 El Rocío-Matalascañas road, 3km south of El Rocío. A former farm in an orange grove with delightful rooms set in beautiful gardens. Excellent bar and restaurant.
• Hotel Toruño (959 44 23 23) This is the best hotel in El Rocío. It is in a great location overlooking the marismas, so you can even birdwatch from your bedroom, if you choose your room carefully (ask for rooms 219, 221, 223 or 223).
Camping
There are many campsites close to the Playa de Castilla beach along the A494 between Mazagón and Matalascañas, which runs alongside the park boundary. In the summer it's well worth booking in advance when the campsites could be full, particularly in August.
• Camping Doñana (959 53 62 81) At the Mazagón end of the A494 at Km34.6, this shady campsite has wooden cabins and tents for rent and a swimming pool.
• Camping La Aldea Located inland on the edge of El Rocío village near the marismas, this campsite has bungalows for hire, a bar and a shop.
• Camping Rocío Playa (959 43 02 38) On the A494 Mazagón-Matalascañas road at Km 45.2, 1½km west of Matalascañas, is this large campsite. Facilities include a restaurant, tennis court, football pitch and a bar with wonderful views. There are wooden bungalows and tents for hire.
Flora
The park supports an incredible array of vegetation in a variety of virgin habitats. Inland are large expanses of stone pines, as well as Mediterranean scrublands, with narrow leaved cistus heather, mastic tree, rosemary, cistus scrub, glasswort, red lavender, rosemary and thyme. There are also junipers and forests of cork oaks, known as "las pajareras" for the enormous quantity of birds that nest in them. Among the flowering plants are lavender, tree heaths, gladioli, irises and rock roses. In the spring the marshlands are covered with flowers.
Fauna
This is a vast wilderness that supports an unrivalled wealth of fauna; 125 species of birds are known to be resident here, as well as 125 migratory bird species, 17 reptiles, nine amphibians and eight species of fish. There is a rich variety of mammals, 28 species in total, with some in danger of extinction, such as the lynx and the Egyptian mongoose. Also here are badgers, rabbits and otters. Game is also plentiful, with red deer, fallow deer and wild boar.
Birds
Doñana comprises delta waters which flood in winter and then drop in the spring leaving rich deposits of silt and raised sandbanks and islands. These conditions are perfect in winter for geese and ducks but most exciting in spring when they draw hundreds of flocks of breeding birds. If you're lucky you may also catch a glimpse of the rare Spanish Imperial Eagle, now down to 15 breeding pairs. In the marshes and amid the cork oak forests behind you've a good chance of seeing grey herons, lanner falcons, ring and turtle doves, partridges, oxpeckers, cattle egret, storks and vultures.
What you see at Doñana depends on the time of year and the luck of the draw - November, December and January constitute the off-season for visitors but is an ideal time for waterfowl, since the autumn rains have brought life back to the marismas and filled the lagunas. Gradually, the water attains a uniform depth of 30-60 centimetres (12-24 inches) over vast areas and the resulting marches attract huge flocks of wildfowl, ducks, geese and other water birds of the most varied kind. These are freshwater marshes, incidentally, although there are traces of sea salt in the underlying silt. Here and there small islands (vetas) rise above the water. These remain dry throughout the year, creating an ideal breeding ground for waders and terns.
Towards the end of February the geese that have migrated here from northern Europe commence their return journey, but at the same time the spoonbills arrive from North Africa to nest in the cork oaks. In March the waters begin to recede and spring begins in earnest. This is also the time when the imperial eagle hatches its eggs: 15 breeding pairs of these formidable hunters were counted recently in the park - above a third of all the imperial eagles known to survive in Spain. Each pair requires nearly 2,600 hectares of land to hunt over in summer, and even more in winter. This is a far from perfect environment for these great birds and Doñana pairs seldom raise as many young as those elsewhere in Spain.
In spring the marismas are alive with birds - some settling down to breed, others en route for more northern climes. Huge numbers of kites hang in the air, harriers send the duck scurrying skywards in fear of their lives. There are black-tailed godwit and ruff on their way to Holland and beyond, greenhank and wood sandpiper bound for Scandinavia, little stint and curlew sandpiper heading for northern Siberia and usually a marsh sandpiper that should be a thousand kilometres or more further east.
Overhead, vast flocks of whiskered terns wheel and circle along with a few gullbilled terns and racy pratincoles. There are swallows galore, some of them red-rumped, and bee-eaters and rollers perch on post and wire. All of these and more can be seen from the bridge at El Rocío - perhaps the best free birdwatching in Europe.
From bird hides at the reserve centre, just south of the bridge, you will hear Cetti's and Savi's warblers and watch egrets, herons and little bitterns come and go. Marsh harriers and kites are continually on view and sometimes a majestic imperial eagle will soar from the woods of Doñana over El Rocío to the Coto del Rey.
In mid-summer the temperature in the parched marismas easily exceeds 40°C. Aquatic birds that remain in the stagnant pools die of botulism, and each year thousands more die during the advancing drought in the Doñana. In August, there is almost nothing left of the marsh's aquatic fauna, but it is a good time for observing dozens of summer residents, which include griffon vulture, booted eagle, red and black kites, short toed eagle, Baillon's crake, purple gallinule, great spotted cuckoo, Scops owl, red necked nightjar, bee eater, hoopoe, calandra, short toed and thekla larks, golden oriole, azure winged magpie. Cetti's and Savi's warblers, tawny pipit, great grey shrike, woodchat shrike and serin.
Rivers
As part of the Guadalquivir delta, the park is riddled with creeks and streams, the main ones being the Brazo de la Torre, the Caño de Guadiamar and Caño Real. The park is dotted with ponds (lucios) that, like the marshlands themselves, can dry up almost completely in summer.
Walks
The core of the park is off-limits to independent walkers. There are footpaths, often with bird hides, leading from the following visitors' centres: El Acebuche, La Rocina and El Palacio del Acebrón. You can also walk alonside the park boundary on the Playa de Castilla, near Matalascañas. A signposted walk, the Sendero Laguna del Jaral Medano del Asperillo, is off the A494 at Km 47. Coming from Matalascañas, there is a car park on the left with an information board and map. It is a challenging circular 5.6km trail that crosses sand dunes and pine woods and will take around 3½ hours. It has superb views of the sea. Make sure you take plenty of water and go when it is not too hot.
Also signposted is the Sendero Cuesta del Maneli. This is a circular trail through the dunes and pine woodland between the road and the beach. It is 2.3km long and takes around 1½ hours and is easier than the Sendero Laguna del Jaral Medano del Asperillo. To get there, take the off the A494 Matalascañas-Mazagón road and at Km 38 there is a car park and information board.

While walking in the Farnham Estate in Cavan I came across this ecosystem in a tree! It reminded me of the giant Kauri tree known as Tane Mahuta in the forest of Waipoua in New Zealand! This may not be quite as big but the range of plants living on it are almost as spectacular!
Prides are family units that may comprise anywhere from two to 40 lions—including up to to three or four males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age.

To consider termites plunderers is unfair. They are the most important animals in a forest ecosystem, single-handedly decomposing 40% to 100% of the decaying wood and thereby enriching the soil. Subterranean termites, which are among the ones that bothers us humans, serve us well too. As they tunnel through the soil, building swarming tubes to forage for food, they increase the soil’s porosity, facilitating greater percolation of water. Termites are known to dig as deep as over 100 feet in search of water to maintain the humidity of their mounds. As early as 500 CE, Indian astronomer Varahamihira wrote in the Brihat-Samhita that termite mounds were indicators of ground water and mineral deposits.

larvae feeds on Ricinus communis and Tragia involucrata.I have yet to locate them.
My biggest fear is that one day, my grandchildren will be looking at my old images and ask me "If you knew these animals were in danger, why did you do nothing? Why did you guys let them disappear?"
I dread the day when that happens; I don't know if I would have the courage to explain to them how we ruined this planet beyond repair...that we were too blinded by our differences, hatred, apathy, and greed to work together to strive for a better Earth and better humanity for future generations.

Yellowstone National Park (Arapaho: Henihco'oo or Héetíhco'oo) is a national park located primarily in the U.S. state of Wyoming, although it also extends into Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone, widely held to be the first national park in the world, is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. It has many types of ecosystems, but the subalpine forest is most abundant. It is part of the South Central Rockies forests ecoregion.
Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-altitude lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone.
Hundreds of species of mammals, birds, fish and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the Continental United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in the park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
The park is located at the headwaters of the Yellowstone River, from which it takes its historical name. Near the end of the 18th century, French trappers named the river "Roche Jaune", which is probably a translation of the Hidatsa name "Mi tsi a-da-zi" (Rock Yellow River). Later, American trappers rendered the French name in English as "Yellow Stone". Although it is commonly believed that the river was named for the yellow rocks seen in the Grand Canyon of the Yellowstone, the Native American name source is not clear.
The first detailed expedition to the Yellowstone area was the Cook–Folsom–Peterson Expedition of 1869, which consisted of three privately funded explorers. The Folsom party followed the Yellowstone River to Yellowstone Lake. The members of the Folsom party kept a journal and based on the information it reported, a party of Montana residents organized the Washburn-Langford-Doane Expedition in 1870. It was headed by the surveyor-general of Montana Henry Washburn, and included Nathaniel P. Langford (who later became known as "National Park" Langford) and a U.S. Army detachment commanded by Lt. Gustavus Doane.
The expedition spent about a month exploring the region, collecting specimens and naming sites of interest. A Montana writer and lawyer named Cornelius Hedges, who had been a member of the Washburn expedition, proposed that the region should be set aside and protected as a national park; he wrote a number of detailed articles about his observations for the Helena Herald newspaper between 1870 and 1871. Hedges essentially restated comments made in October 1865 by acting Montana Territorial Governor Thomas Francis Meagher, who had previously commented that the region should be protected. Others made similar suggestions. In an 1871 letter from Jay Cooke to Ferdinand V. Hayden, Cooke wrote that his friend, Congressman William D. Kelley had also suggested "Congress pass a bill reserving the Great Geyser Basin as a public park forever".
By 1915, 1,000 automobiles per year were entering the park, resulting in conflicts with horses and horse-drawn transportation. Horse travel on roads was eventually prohibited.
The Civilian Conservation Corps (CCC), a New Deal relief agency for young men, played a major role between 1933 and 1942 in developing Yellowstone facilities. CCC projects included reforestation, campground development of many of the park's trails and campgrounds, trail construction, fire hazard reduction, and fire-fighting work. The CCC built the majority of the early visitor centers, campgrounds and the current system of park roads.
During World War II, tourist travel fell sharply, staffing was cut, and many facilities fell into disrepair. By the 1950s, visitation increased tremendously in Yellowstone and other national parks. To accommodate the increased visitation, park officials implemented Mission 66, an effort to modernize and expand park service facilities. Planned to be completed by 1966, in honor of the 50th anniversary of the founding of the National Park Service, Mission 66 construction diverged from the traditional log cabin style with design features of a modern style. During the late 1980s, most construction styles in Yellowstone reverted to the more traditional designs. After the enormous forest fires of 1988 damaged much of Grant Village, structures there were rebuilt in the traditional style. The visitor center at Canyon Village, which opened in 2006, incorporates a more traditional design as well.

The 1959 Hebgen Lake earthquake just west of Yellowstone at Hebgen Lake damaged roads and some structures in the park. In the northwest section of the park, new geysers were found, and many existing hot springs became turbid. It was the most powerful earthquake to hit the region in recorded history.
In 1963, after several years of public controversy regarding the forced reduction of the elk population in Yellowstone, United States Secretary of the Interior Stewart Udall appointed an advisory board to collect scientific data to inform future wildlife management of the national parks. In a paper known as the Leopold Report, the committee observed that culling programs at other national parks had been ineffective, and recommended management of Yellowstone's elk population.
The wildfires during the summer of 1988 were the largest in the history of the park. Approximately 793,880 acres (321,272 ha; 1,240 sq mi) or 36% of the parkland was impacted by the fires, leading to a systematic re-evaluation of fire management policies. The fire season of 1988 was considered normal until a combination of drought and heat by mid-July contributed to an extreme fire danger. On "Black Saturday", August 20, 1988, strong winds expanded the fires rapidly, and more than 150,000 acres (61,000 ha; 230 sq mi) burned.
The expansive cultural history of the park has been documented by the 1,000 archeological sites that have been discovered. The park has 1,106 historic structures and features, and of these Obsidian Cliff and five buildings have been designated National Historic Landmarks. Yellowstone was designated an International Biosphere Reserve on October 26, 1976, and a UN World Heritage Site on September 8, 1978. The park was placed on the List of World Heritage in Danger from 1995 to 2003 due to the effects of tourism, infection of wildlife, and issues with invasive species. In 2010, Yellowstone National Park was honored with its own quarter under the America the Beautiful Quarters Program.
Heritage and Research Center
The Heritage and Research Center is located at Gardiner, Montana, near the north entrance to the park. The center is home to the Yellowstone National Park's museum collection, archives, research library, historian, archeology lab, and herbarium. The Yellowstone National Park Archives maintain collections of historical records of Yellowstone and the National Park Service. The collection includes the administrative records of Yellowstone, as well as resource management records, records from major projects, and donated manuscripts and personal papers. The archives are affiliated with the National Archives and Records Administration.
Approximately 96 percent of the land area of Yellowstone National Park is located within the state of Wyoming. Another three percent is within Montana, with the remaining one percent in Idaho. The park is 63 miles (101 km) north to south, and 54 miles (87 km) west to east by air. Yellowstone is 2,219,789 acres (898,317 ha; 3,468.420 sq mi) in area, larger than the states of Rhode Island or Delaware. Rivers and lakes cover five percent of the land area, with the largest water body being Yellowstone Lake at 87,040 acres (35,220 ha; 136.00 sq mi). Yellowstone Lake is up to 400 feet (120 m) deep and has 110 miles (180 km) of shoreline. At an elevation of 7,733 feet (2,357 m) above sea level, Yellowstone Lake is the largest high altitude lake in North America. Forests comprise 80 percent of the land area of the park; most of the rest is grassland.
The Continental Divide of North America runs diagonally through the southwestern part of the park. The divide is a topographic feature that separates Pacific Ocean and Atlantic Ocean water drainages. About one third of the park lies on the west side of the divide. The origins of the Yellowstone and Snake Rivers are near each other but on opposite sides of the divide. As a result, the waters of the Snake River flow to the Pacific Ocean, while those of the Yellowstone find their way to the Atlantic Ocean via the Gulf of Mexico.
The park sits on the Yellowstone Plateau, at an average elevation of 8,000 feet (2,400 m) above sea level. The plateau is bounded on nearly all sides by mountain ranges of the Middle Rocky Mountains, which range from 9,000 to 11,000 feet (2,700 to 3,400 m) in elevation. The highest point in the park is atop Eagle Peak (11,358 feet or 3,462 metres) and the lowest is along Reese Creek (5,282 feet or 1,610 metres). Nearby mountain ranges include the Gallatin Range to the northwest, the Beartooth Mountains in the north, the Absaroka Range to the east, and the Teton Range and the Madison Range to the southwest and west. The most prominent summit on the Yellowstone Plateau is Mount Washburn at 10,243 feet (3,122 m).
Yellowstone National Park has one of the world's largest petrified forests, trees which were long ago buried by ash and soil and transformed from wood to mineral materials. This ash and other volcanic debris, are believed to have come from the park area itself. This is largely due to the fact that Yellowstone is actually a massive caldera of a supervolcano. There are 290 waterfalls of at least 15 feet (4.6 m) in the park, the highest being the Lower Falls of the Yellowstone River at 308 feet (94 m).
Three deep canyons are located in the park, cut through the volcanic tuff of the Yellowstone Plateau by rivers over the last 640,000 years. The Lewis River flows through Lewis Canyon in the south, and the Yellowstone River has carved two colorful canyons, the Grand Canyon of the Yellowstone and the Black Canyon of the Yellowstone in its journey north.
Yellowstone is at the northeastern end of the Snake River Plain, a great U-shaped arc through the mountains that extends from Boise, Idaho some 400 miles (640 km) to the west. This feature traces the route of the North American Plate over the last 17 million years as it was transported by plate tectonics across a stationary mantle hotspot. The landscape of present-day Yellowstone National Park is the most recent manifestation of this hotspot below the crust of the Earth.
The Yellowstone Caldera is the largest volcanic system in North America. It has been termed a "supervolcano" because the caldera was formed by exceptionally large explosive eruptions. The magma chamber that lies under Yellowstone is estimated to be a single connected chamber, about 37 miles (60 km) long, 18 miles (29 km) wide, and 3 to 7 miles (5 to 12 km) deep. The current caldera was created by a cataclysmic eruption that occurred 640,000 years ago, which released more than 240 cubic miles (1,000 km³) of ash, rock and pyroclastic materials. This eruption was more than 1,000 times larger than the 1980 eruption of Mount St. Helens. It produced a caldera nearly five eighths of a mile (1 km) deep and 45 by 28 miles (72 by 45 km) in area and deposited the Lava Creek Tuff, a welded tuff geologic formation. The most violent known eruption, which occurred 2.1 million years ago, ejected 588 cubic miles (2,450 km³) of volcanic material and created the rock formation known as the Huckleberry Ridge Tuff and created the Island Park Caldera. A smaller eruption ejected 67 cubic miles (280 km³) of material 1.3 million years ago, forming the Henry's Fork Caldera and depositing the Mesa Falls Tuff.
Each of the three climactic eruptions released vast amounts of ash that blanketed much of central North America, falling many hundreds of miles away. The amount of ash and gases released into the atmosphere probably caused significant impacts to world weather patterns and led to the extinction of some species, primarily in North America.

A subsequent caldera-forming eruption occurred about 160,000 years ago. It formed the relatively small caldera that contains the West Thumb of Yellowstone Lake. Since the last supereruption, a series of smaller eruptive cycles between 640,000 and 70,000 years ago, has nearly filled in the Yellowstone Caldera with >80 different eruptions of rhyolitic lavas such as those that can be seen at Obsidian Cliffs and basaltic lavas which can be viewed at Sheepeater Cliff. Lava strata are most easily seen at the Grand Canyon of the Yellowstone, where the Yellowstone River continues to carve into the ancient lava flows. The canyon is a classic V-shaped valley, indicative of river-type erosion rather than erosion caused by glaciation.
Each eruption is part of an eruptive cycle that climaxes with the partial collapse of the roof of the volcano's partially emptied magma chamber. This creates a collapsed depression, called a caldera, and releases vast amounts of volcanic material, usually through fissures that ring the caldera. The time between the last three cataclysmic eruptions in the Yellowstone area has ranged from 600,000 to 800,000 years, but the small number of such climactic eruptions cannot be used to make an accurate prediction for future volcanic events.
The most famous geyser in the park, and perhaps the world, is Old Faithful Geyser, located in Upper Geyser Basin. Castle Geyser, Lion Geyser and Beehive Geyser are in the same basin. The park contains the largest active geyser in the world—Steamboat Geyser in the Norris Geyser Basin. A study that was completed in 2011 found that at least 1283 geysers have erupted in Yellowstone. Of these, an average of 465 are active in a given year. Yellowstone contains at least 10,000 geothermal features altogether. Half the geothermal features and two-thirds of the world's geysers are concentrated in Yellowstone.
In May 2001, the U.S. Geological Survey, Yellowstone National Park, and the University of Utah created the Yellowstone Volcano Observatory (YVO), a partnership for long-term monitoring of the geological processes of the Yellowstone Plateau volcanic field, for disseminating information concerning the potential hazards of this geologically active region.
In 2003, changes at the Norris Geyser Basin resulted in the temporary closure of some trails in the basin. New fumaroles were observed, and several geysers showed enhanced activity and increasing water temperatures. Several geysers became so hot that they were transformed into purely steaming features; the water had become superheated and they could no longer erupt normally. This coincided with the release of reports of a multiple year United States Geological Survey research project which mapped the bottom of Yellowstone Lake and identified a structural dome that had uplifted at some time in the past. Research indicated that these uplifts posed no immediate threat of a volcanic eruption, since they may have developed long ago, and there had been no temperature increase found near the uplifts. On March 10, 2004, a biologist discovered 5 dead bison which apparently had inhaled toxic geothermal gases trapped in the Norris Geyser Basin by a seasonal atmospheric inversion. This was closely followed by an upsurge of earthquake activity in April 2004. In 2006, it was reported that the Mallard Lake Dome and the Sour Creek Dome— areas that have long been known to show significant changes in their ground movement— had risen at a rate of 1.5 to 2.4 inches (3.8 to 6.1 cm) per year from mid–2004 through 2006. As of late 2007, the uplift has continued at a reduced rate. These events inspired a great deal of media attention and speculation about the geologic future of the region. Experts responded to the conjecture by informing the public that there was no increased risk of a volcanic eruption in the near future. However, these changes demonstrate the dynamic nature of the Yellowstone hydrothermal system.
Yellowstone experiences thousands of small earthquakes every year, virtually all of which are undetectable to people. There have been six earthquakes with at least magnitude 6 or greater in historical times, including a 7.5‑magnitude quake that struck just outside the northwest boundary of the park in 1959. This quake triggered a huge landslide, which caused a partial dam collapse on Hebgen Lake; immediately downstream, the sediment from the landslide dammed the river and created a new lake, known as Earthquake Lake. Twenty-eight people were killed, and property damage was extensive in the immediate region. The earthquake caused some geysers in the northwestern section of the park to erupt, large cracks in the ground formed and emitted steam, and some hot springs that normally have clear water turned muddy. A 6.1‑magnitude earthquake struck inside the park on June 30, 1975, but damage was minimal.
For three months in 1985, 3,000 minor earthquakes were detected in the northwestern section of the park, during what has been referred to as an earthquake swarm, and has been attributed to minor subsidence of the Yellowstone caldera. Beginning on April 30, 2007, 16 small earthquakes with magnitudes up to 2.7 occurred in the Yellowstone Caldera for several days. These swarms of earthquakes are common, and there have been 70 such swarms between 1983 and 2008. In December 2008, over 250 earthquakes were measured over a four-day span under Yellowstone Lake, the largest measuring a magnitude of 3.9. In January 2010, more than 250 earthquakes were detected over a two-day period. Seismic activity in Yellowstone National Park continues and is reported hourly by the Earthquake Hazards Program of the U.S. Geological Survey.
On March 30, 2014, a magnitude 4.8 earthquake struck almost the very middle of Yellowstone near the Norris Basin at 6.34am; reports indicated no damage. This was the biggest earthquake to hit the park since February 22, 1980.
Over 1,700 species of trees and other vascular plants are native to the park. Another 170 species are considered to be exotic species and are non-native. Of the eight conifer tree species documented, Lodgepole Pine forests cover 80% of the total forested areas. Other conifers, such as Subalpine Fir, Engelmann Spruce, Rocky Mountain Douglas-fir and Whitebark Pine, are found in scattered groves throughout the park. As of 2007, the whitebark pine is threatened by a fungus known as white pine blister rust; however, this is mostly confined to forests well to the north and west. In Yellowstone, about seven percent of the whitebark pine species have been impacted with the fungus, compared to nearly complete infestations in northwestern Montana. Quaking Aspen and willows are the most common species of deciduous trees. The aspen forests have declined significantly since the early 20th century, but scientists at Oregon State University attribute recent recovery of the aspen to the reintroduction of wolves which has changed the grazing habits of local elk.
There are dozens of species of flowering plants that have been identified, most of which bloom between the months of May and September. The Yellowstone Sand Verbena is a rare flowering plant found only in Yellowstone. It is closely related to species usually found in much warmer climates, making the sand verbena an enigma. The estimated 8,000 examples of this rare flowering plant all make their home in the sandy soils on the shores of Yellowstone Lake, well above the waterline.
In Yellowstone's hot waters, bacteria form mats of bizarre shapes consisting of trillions of individuals. These bacteria are some of the most primitive life forms on earth. Flies and other arthropods live on the mats, even in the middle of the bitterly cold winters. Initially, scientists thought that microbes there gained sustenance only from sulfur. In 2005 researchers from the University of Colorado at Boulder discovered that the sustenance for at least some of the diverse hyperthermophilic species is molecular hydrogen.
Thermus aquaticus is a bacterium found in the Yellowstone hot springs that produces an important enzyme (Taq polymerase) that is easily replicated in the lab and is useful in replicating DNA as part of the polymerase chain reaction (PCR) process. The retrieval of these bacteria can be achieved with no impact to the ecosystem. Other bacteria in the Yellowstone hot springs may also prove useful to scientists who are searching for cures for various diseases.
Non-native plants sometimes threaten native species by using up nutrient resources. Though exotic species are most commonly found in areas with the greatest human visitation, such as near roads and at major tourist areas, they have also spread into the backcountry. Generally, most exotic species are controlled by pulling the plants out of the soil or by spraying, both of which are time consuming and expensive.
Yellowstone is widely considered to be the finest megafauna wildlife habitat in the lower 48 states. There are almost 60 species of mammals in the park, including the gray wolf, the threatened lynx, and grizzly bears. Other large mammals include the bison (often referred to as buffalo), black bear, elk, moose, mule deer, white-tailed deer, mountain goat, pronghorn, bighorn sheep, and mountain lion.
Bison graze near a hot spring
The Yellowstone Park bison herd is the largest public herd of American bison in the United States. The relatively large bison populations are a concern for ranchers, who fear that the species can transmit bovine diseases to their domesticated cousins. In fact, about half of Yellowstone's bison have been exposed to brucellosis, a bacterial disease that came to North America with European cattle that may cause cattle to miscarry. The disease has little effect on park bison, and no reported case of transmission from wild bison to domestic livestock has been filed. However, the Animal and Plant Health Inspection Service (APHIS) has stated that bison are the "likely source" of the spread of the disease in cattle in Wyoming and North Dakota. Elk also carry the disease and are believed to have transmitted the infection to horses and cattle. Bison once numbered between 30 and 60 million individuals throughout North America, and Yellowstone remains one of their last strongholds. Their populations had increased from less than 50 in the park in 1902 to 4,000 by 2003. The Yellowstone Park bison herd reached a peak in 2005 with 4,900 animals. Despite a summer estimated population of 4,700 in 2007, the number dropped to 3,000 in 2008 after a harsh winter and controversial brucellosis management sending hundreds to slaughter. The Yellowstone Park bison herd is believed to be one of only four free roaming and genetically pure herds on public lands in North America. The other three herds are the Henry Mountains bison herd of Utah, at Wind Cave National Park in South Dakota and on Elk Island in Alberta.
Elk Mother Nursing Her Calf
To combat the perceived threat of brucellosis transmission to cattle, national park personnel regularly harass bison herds back into the park when they venture outside of the area's borders. During the winter of 1996–97, the bison herd was so large that 1,079 bison that had exited the park were shot or sent to slaughter. Animal rights activists argue that this is a cruel practice and that the possibility for disease transmission is not as great as some ranchers maintain. Ecologists point out that the bison are merely traveling to seasonal grazing areas that lie within the Greater Yellowstone Ecosystem that have been converted to cattle grazing, some of which are within National Forests and are leased to private ranchers. APHIS has stated that with vaccinations and other means, brucellosis can be eliminated from the bison and elk herds throughout Yellowstone.
A reintroduced northwestern wolf in Yellowstone National Park
Starting in 1914, in an effort to protect elk populations, the U.S. Congress appropriated funds to be used for the purposes of "destroying wolves, prairie dogs, and other animals injurious to agriculture and animal husbandry" on public lands. Park Service hunters carried out these orders, and by 1926 they had killed 136 wolves, and wolves were virtually eliminated from Yellowstone. Further exterminations continued until the National Park Service ended the practice in 1935. With the passing of the Endangered Species Act in 1973, the wolf was one of the first mammal species listed. After the wolves were extirpated from Yellowstone, the coyote then became the park's top canine predator. However, the coyote is not able to bring down large animals, and the result of this lack of a top predator on these populations was a marked increase in lame and sick megafauna.
Bison in Yellowstone National Park
By the 1990s, the Federal government had reversed its views on wolves. In a controversial decision by the U.S. Fish and Wildlife Service (which oversees threatened and endangered species), northwestern wolves, imported from Canada, were reintroduced into the park. Reintroduction efforts have been successful with populations remaining relatively stable. A survey conducted in 2005 reported that there were 13 wolf packs, totaling 118 individuals in Yellowstone and 326 in the entire ecosystem. These park figures were lower than those reported in 2004 but may be attributable to wolf migration to other nearby areas as suggested by the substantial increase in the Montana population during that interval. Almost all the wolves documented were descended from the 66 wolves reintroduced in 1995–96. The recovery of populations throughout the states of Wyoming, Montana and Idaho has been so successful that on February 27, 2008, the U.S. Fish and Wildlife Service removed the Northern Rocky Mountain wolf population from the endangered species list.
An estimated 600 grizzly bears live in the Greater Yellowstone Ecosystem, with more than half of the population living within Yellowstone. The grizzly is currently listed as a threatened species, however the U.S. Fish and Wildlife Service has announced that they intend to take it off the endangered species list for the Yellowstone region but will likely keep it listed in areas where it has not yet recovered fully. Opponents of delisting the grizzly are concerned that states might once again allow hunting and that better conservation measures need to be implemented to ensure a sustainable population. Black bears are common in the park and were a park symbol due to visitor interaction with the bears starting in 1910. Feeding and close contact with bears has not been permitted since the 1960s to reduce their desire for human foods. Yellowstone is one of the few places in the United States where black bears can be seen coexisting with grizzly bears. Black bear observations occur most often in the park's northern ranges and in the Bechler area which is in the park's southwestern corner.
Population figures for elk are in excess of 30,000—the largest population of any large mammal species in Yellowstone. The northern herd has decreased enormously since the mid‑1990s; this has been attributed to wolf predation and causal effects such as elk using more forested regions to evade predation, consequently making it harder for researchers to accurately count them. The northern herd migrates west into southwestern Montana in the winter. The southern herd migrates southward, and the majority of these elk winter on the National Elk Refuge, immediately southeast of Grand Teton National Park. The southern herd migration is the largest mammalian migration remaining in the U.S. outside of Alaska.
In 2003 the tracks of one female lynx and her cub were spotted and followed for over 2 miles (3.2 km). Fecal material and other evidence obtained were tested and confirmed to be those of a lynx. No visual confirmation was made, however. Lynx have not been seen in Yellowstone since 1998, though DNA taken from hair samples obtained in 2001 confirmed that lynx were at least transient to the park. Other less commonly seen mammals include the mountain lion and wolverine. The mountain lion has an estimated population of only 25 individuals parkwide. The wolverine is another rare park mammal, and accurate population figures for this species are not known. These uncommon and rare mammals provide insight into the health of protected lands such as Yellowstone and help managers make determinations as to how best to preserve habitats.
Eighteen species of fish live in Yellowstone, including the core range of the Yellowstone cutthroat trout—a fish highly sought by anglers. The Yellowstone cutthroat trout has faced several threats since the 1980s, including the suspected illegal introduction into Yellowstone Lake of lake trout, an invasive species which consume the smaller cutthroat trout. Although lake trout were established in Shoshone and Lewis lakes in the Snake River drainage from U.S. Government stocking operations in 1890, it was never officially introduced into the Yellowstone River drainage. The cutthroat trout has also faced an ongoing drought, as well as the accidental introduction of a parasite—whirling disease—which causes a terminal nervous system disease in younger fish. Since 2001, all native sport fish species caught in Yellowstone waterways are subject to a catch and release law. Yellowstone is also home to six species of reptiles, such as the painted turtle and Prairie rattlesnake, and four species of amphibians, including the Boreal Chorus Frog.
311 species of birds have been reported, almost half of which nest in Yellowstone. As of 1999, twenty-six pairs of nesting bald eagles have been documented. Extremely rare sightings of whooping cranes have been recorded, however only three examples of this species are known to live in the Rocky Mountains, out of 385 known worldwide. Other birds, considered to be species of special concern because of their rarity in Yellowstone, include the common loon, harlequin duck, osprey, peregrine falcon and the trumpeter swan.
As wildfire is a natural part of most ecosystems, plants that are indigenous to Yellowstone have adapted in a variety of ways. Douglas-fir have a thick bark which protects the inner section of the tree from most fires. Lodgepole Pines —the most common tree species in the park— generally have cones that are only opened by the heat of fire. Their seeds are held in place by a tough resin, and fire assists in melting the resin, allowing the seeds to disperse. Fire clears out dead and downed wood, providing fewer obstacles for lodgepole pines to flourish. Subalpine Fir, Engelmann Spruce, Whitebark Pine, and other species tend to grow in colder and moister areas, where fire is less likely to occur. Aspen trees sprout new growth from their roots, and even if a severe fire kills the tree above ground, the roots often survive unharmed because they are insulated from the heat by soil. The National Park Service estimates that in natural conditions, grasslands in Yellowstone burned an average of every 20 to 25 years, while forests in the park would experience fire about every 300 years.
About thirty-five natural forest fires are ignited each year by lightning, while another six to ten are started by people— in most cases by accident. Yellowstone National Park has three fire lookout towers, each staffed by trained fire fighters. The easiest one to reach is atop Mount Washburn, though it is closed to the public. The park also monitors fire from the air and relies on visitor reports of smoke and/or flames. Fire towers are staffed almost continuously from late June to mid-September— the primary fire season. Fires burn with the greatest intensity in the late afternoon and evening. Few fires burn more than 100 acres (40 ha), and the vast majority of fires reach only a little over an acre (0.5 ha) before they burn themselves out. Fire management focuses on monitoring dead and down wood quantities, soil and tree moisture, and the weather, to determine those areas most vulnerable to fire should one ignite. Current policy is to suppress all human caused fires and to evaluate natural fires, examining the benefit or detriment they may pose on the ecosystem. If a fire is considered to be an immediate threat to people and structures, or will burn out of control, then fire suppression is performed.
In an effort to minimize the chances of out of control fires and threats to people and structures, park employees do more than just monitor the potential for fire. Controlled burns are prescribed fires which are deliberately started to remove dead timber under conditions which allow fire fighters an opportunity to carefully control where and how much wood is consumed. Natural fires are sometimes considered prescribed fires if they are left to burn. In Yellowstone, unlike some other parks, there have been very few fires deliberately started by employees as prescribed burns. However, over the last 30 years, over 300 natural fires have been allowed to burn naturally. In addition, fire fighters remove dead and down wood and other hazards from areas where they will be a potential fire threat to lives and property, reducing the chances of fire danger in these areas. Fire monitors also regulate fire through educational services to the public and have been known to temporarily ban campfires from campgrounds during periods of high fire danger. The common notion in early United States land management policies was that all forest fires were bad. Fire was seen as a purely destructive force and there was little understanding that it was an integral part of the ecosystem. Consequently, until the 1970s, when a better understanding of wildfire was developed, all fires were suppressed. This led to an increase in dead and dying forests, which would later provide the fuel load for fires that would be much harder, and in some cases, impossible to control. Fire Management Plans were implemented, detailing that natural fires should be allowed to burn if they posed no immediate threat to lives and property.
1988 started with a wet spring season although by summer, drought began moving in throughout the northern Rockies, creating the driest year on record to that point. Grasses and plants which grew well in the early summer from the abundant spring moisture produced plenty of grass, which soon turned to dry tinder. The National Park Service began firefighting efforts to keep the fires under control, but the extreme drought made suppression difficult. Between July 15 and 21, 1988, fires quickly spread from 8,500 acres (3,400 ha; 13.3 sq mi) throughout the entire Yellowstone region, which included areas outside the park, to 99,000 acres (40,000 ha; 155 sq mi) on the park land alone. By the end of the month, the fires were out of control. Large fires burned together, and on August 20, 1988, the single worst day of the fires, more than 150,000 acres (61,000 ha; 230 sq mi) were consumed. Seven large fires were responsible for 95% of the 793,000 acres (321,000 ha; 1,239 sq mi) that were burned over the next couple of months. A total of 25,000 firefighters and U.S. military forces participated in the suppression efforts, at a cost of 120 million dollars. By the time winter brought snow that helped extinguish the last flames, the fires had destroyed 67 structures and caused several million dollars in damage. Though no civilian lives were lost, two personnel associated with the firefighting efforts were killed.
Contrary to media reports and speculation at the time, the fires killed very few park animals— surveys indicated that only about 345 elk (of an estimated 40,000–50,000), 36 deer, 12 moose, 6 black bears, and 9 bison had perished. Changes in fire management policies were implemented by land management agencies throughout the United States, based on knowledge gained from the 1988 fires and the evaluation of scientists and experts from various fields. By 1992, Yellowstone had adopted a new fire management plan which observed stricter guidelines for the management of natural fires.

In 2008 the United Nations Environment Program expressed extreme concern for the implications of climate change on the Arctic regions. A warming Arctic climate is projected to change sea temperature and melt ice sheets, destroying vital ecosystems which operate in these Arctic areas. According to NASA, even small changes in ice could mean drastic changes to our water cycle and global climate.

Bee Butts — Well, we may not "Break the Internet" with this one, but we like bee butts and we cannot lie!
This is the backend of a Lipotriches (Plain Sweat Bee) collected in Australia. This is one of the bees in which the males are known to form sleeping aggregations – small groups to dozens of individuals clustering together on the same twig late in the afternoon and remaining there until after dawn. There may be quite a lot of “jockeying for position” as males alight too close to another individual with low key aggressive interactions. Some clusters might contain more than one species. There has been little research on the reason for this aggregating behavior, although safety in numbers might play a role.
