I don't do many black and white photos, but sometimes the subject just cries out for the monochrome treatment. This is an old photo taken at a Christchurch motorcycle show back in 2012. The subject is the well known and much modified 1920 Indian Scout developed over many years by Burt Munro. Virtually everything is hand built with extensive alterations to the frame and engine including hand built pistons, conrods, and rockers. After Burt passed away the bike was owned by Norm Hayes and at the time kept at his home. I remember visiting Norm and seeing the bike and, the almost as special shelves, painted with the inscription "Offerings to the God of Speed" The shelf contents were fascinating with molds for casting pistons, and many broken parts including pistons and cylinders. Among the items was the thinnest cross section valve rocker I have ever seen. The end of the rocker was broken off. An old brown cardboard luggage label was tied to the rocker with writing proclaiming this rocker to be the remains of the 103rd engine blow up.
So this weeks image represents tenacity to keep going and eventually like Burt after working on the bike for nearly 50 years, achieve the success he wanted.
On this brisk autumn day, these Chinese Tallow tree leaves are hanging on for dear life and wish they had a proper branch to hang from.

More fados here.
Ive photographed this tree often. Partially felled by strong wind/lightning, it continues to produce leaves in an attempt to survive. It hasn't and won't give up on life. A good reminder.
... the dedication series ... drawing inspiration from my flickr contacts.
When I first joined Flickr, I never expected that membership would be an avenue to restore my faith in humanity, For the most part my Flickr experience has been overwhelmingly positive. There have been some very dark moments too, which have proven to be invaluable insights. However, today is not the day to dwell on those matters.
The tenacious spirit of a number of my contacts shines through as they face addiction, chronic/ terminal illness or deeply personal tragedy. Their photography is a testament to their personal determination and the the strength of the human spirit to rise above circumstances. One does not have to search far to be touched by these stories, or to find the outpouring of raw emotions or support for others.
Bad things happen to good people. It is part of the human condition. For me it is not so much a question of why these things happen, but how do I allow my self to feel, how will I respond, what actions will I take in my life as a result of that knowledge. I believe in the positive ripple effect created by random acts of kindness. I believe in the power of the individual to create positive change through small intentional acts. I believe that even in the darkness there is room for hope.
Today's post is a dedication to an extremely talented artist, whose photography contained that tenacious spirit of humanity way before personal tragedy and illness has left him fighting for his life. Jackson, this one is for you and your family and in support of your cause.

" Nature needs no help, just no interference." BJ Palmer (Thanks Gloria for the quote.)
This little campanula has self-seeded itself into a wall about 2 metres above its brothers and sisters that are growing more normally in soil at the bottom of the wall.
Isn't nature resourceful and will quickly take over and make use of man-made structures!

Bowed by the forces of nature, yet determined to survive. The struggles it faces in the face of adversity strengthens its resolve to live.
This is an image of hope. A homage to tenacity. Holding on to trust
on the path that winds its way through dark trees on a starless night.
The sun will shine tomorrow,
and even today is a clear sky if you are high above the clouds.
Spring will inevitably come
and the lavender will waft it's heady perfume across the way.

Opuntia, commonly called prickly pear, is a genus of flowering plants in the cactus family Cactaceae. When Carl Linnaeus published Species Plantarum in 1753 – the starting point for modern botanical nomenclature – he placed all the species of cactus known to him in one genus, Cactus. In 1754, the Scottish botanist Philip Miller divided them into several genera, including Opuntia. He distinguished the genus largely on the form of its flowers and fruits.
Like most true cactus species, prickly pears are native only to the Americas. Through human actions, they have since been introduced to many other areas of the world. Prickly pears are considered an invasive species in Australia, Ethiopia, South Africa, and Hawaii, among other locations.
Prickly pears (mostly Opuntia stricta) were originally imported into Europe during the 1500s and Australia in the 18th century for gardens, and were later used as a natural agricultural fencing and in an attempt to establish a cochineal dye industry.
In Australia, they quickly became a widespread invasive weed, eventually converting 260,000 km2 (101,000 sq mi) of farming land into an impenetrable green jungle of prickly pear, in places 6 m (20 ft) high. Scores of farmers were driven off their land by what they called the "green hell"; their abandoned homes were crushed under the cactus growth, which advanced at a rate of 400,000 hectares (1,000,000 acres) per year.
The moth Cactoblastis cactorum, from South America, whose larvae eat prickly pear, was introduced in 1925 and rapidly reduced the cactus population. The son of the noted entomologist Frederick Parkhurst Dodd, Alan Dodd, was a leading official in combating the prickly pear menace. A memorial hall in Chinchilla, Queensland, commemorates the moth.
Animals that eat Opuntia include the prickly pear island snail and Cyclura rock iguanas. The fruit are relished by many arid-land animals, chiefly birds, which thus help distribute the seeds. Opuntia pathogens include the sac fungus Colletotrichum coccodes and Sammons' Opuntia virus. The ant Crematogaster opuntiae and the spider Theridion opuntia are named because of their association with prickly pear cactus.
The fruit of prickly pears, commonly called cactus fruit, cactus fig, Indian fig, nopales or tuna in Spanish, is edible, although it must be peeled carefully to remove the small spines on the outer skin before consumption. If the outer layer is not properly removed, glochids can be ingested, causing discomfort of the throat, lips, and tongue, as the small spines are easily lodged in the skin. Native Americans like the Tequesta would roll the fruit around in a suitable medium (e.g. grit) to "sand" off the glochids. Alternatively, rotating the fruit in the flame of a campfire or torch has been used to remove the glochids. Today, parthenocarpic (seedless) cultivars are also available.
Prior to modern medicine, Native Americans and Mexicans primarily used Opuntia as a coagulant for open wounds, using the pulp of the stem either by splitting the stem or scraping out the pulp.
In one recent study, it was found that Opuntia aided in the prevention or slow down of diabetes, obesity, metabolic syndrome, cardiovascular disease, and some cancers. The results of the group that was taking Opuntia showed a reduction in BMI, body composition, and waist circumference when compared to the placebo group.
The coat of arms of Mexico depicts a Mexican golden eagle, perched upon an Opuntia cactus, holding a rattlesnake. According to the official history of Mexico, the coat of arms is inspired by an Aztec legend regarding the founding of Tenochtitlan.
The Aztecs, then a nomadic tribe, were wandering throughout Mexico in search of a divine sign to indicate the precise spot upon which they were to build their capital. Their god Huitzilopochtli had commanded them to find an eagle devouring a snake, perched atop a cactus that grew on a rock submerged in a lake. After 200 years of wandering, they found the promised sign on a small island in the swampy Lake Texcoco. There they founded their new capital, Tenochtitlan.

I think there is a spiral of some sort here in this wildflower basal growth. The Zoom seemed to emphasize the lines and blurred the prominent texture, which I found distracting.
The injured cape buffalo repeatedly fends off the pride, alone and with the help of other herd members. Each time it tries to recover and rest the pride closes in, never giving the bull a chance to regain any strength. He is injured. His left front leg is broken. This injury is likely the reason he is being singled out. It is much less likely that the injury was inflicted by the lions, since none of them is reckless enough to try and approach the bull from the front. Even now, injured and weakened, the bull could easily inflict mortal injury on the lions. They feel him growing weaker, however. They remain patient and persistent. I find myself wishing that the bull would simply lose consciousness. His fear and suffering are all too apparent. I am bothered by watching, yet I cannot look away. It vexes me. On a rare instance like this, nature has made me uncomfortable. I am uncomfortable with suffering, regardless of the subject. #iLoveNature #iLoveWildlife #WildlifePhotography in #Tanzania #Nature in #Africa #Ngorongoro #Canon #Bringit #DrDADBooks #Photography #Picoftheday #Photooftheday #WildlifeConservation

Character actor Raymond Aimos (1891–1944) or simply Aimos was one of the familiar faces of the French cinema of the 1930s and early 1940s. During this golden age of poetic realism, he was the quintessential 'Titi Parisien' (Parisian kid) in at least 105 films. His film characters generally corresponded with himself: humble, poor, colourful, cheeky but with a heart of gold.
Raymond Aimos was born as Raymond Arthur Coudurier in La Fère in the North of France in 1891 (1889 (sic) according to IMDb and other sources). He was the son of a watchmaker-jeweler and was expected to work in the family business but young Raymond was uncontrollably attracted to show business. He managed to become an opera singer under the stage name Aimos. According to urban legends, retold by different sources, he made his first film appearance as a kid either in the Lumière brothers’ L’arroseur arose/The Sprinkler Sprinkled (1895, Louis Lumière) or in a film by another legendary film pioneer, Georges Méliès. (In the first film, the naughty boy was Benoît Duval). However, officially Aimos made his cinema debut in the short silent western Pendaison à Jefferson City/Hanging at Jefferson City (1910, Jean Durand) with Joë Hamman and Gaston Modot. He appeared in more early silent shorts, like the Onesime comedies Onésime et le nourrisson de la nourrice indigne/ Onesimus and the infant unworthy of the nurse (1912, Jean Durand), Onésime a un duel à l'américaine/Onesime has an American-style duel (1912, Jean Durand) and Onésime horloger/Onesime, Clockmaker (1912, Jean Durand), all starring Ernest Bourbon aka Onésime. A decade later, Aimos appeared in the Three Musketeers-sequel Vingt Ans après/Five Years Later (1922, Henri Diamant-Berger), based on the novel by Alexandre Dumas père. These film parts had all been modest, but Aimos’ lucky strike would be the coming of sound.
Aimos' physical appearance, his popular roots and mostly his gift of gab were in perfect harmony with the sound cinema of the 1930s. He was wonderful as a humble man of the people in two masterpieces by René Clair, Sous les toits de Paris/Under the Roofs of Paris (1930) starring Albert Préjean, and Quatorze juillet/July 14 (1933) with Annabella. It lead to more work for important directors. He appeared for Raymond Bernard as a soldier in the war drama Les croix de bois/Wooden Crosses (1932) with Pierre Blanchar, and a clochard in Amants et voleurs/Lovers and Thieves (1935) with Arletty, for Sacha Guitry as another clochard in Ils étaient neuf célibataires/Nine Bachelors (1939), for Marcel Carné as Quart-Vittel, the wreck in Quai des brumes/Port of Shadows (1938), and for Jean Grémillon in Lumière d'été/Summer Light (1943) starring Madeleine Renaud. His most memorable roles were in the films by Julien Duvivier, such as Mulot, the legionary friend of Jean Gabin in La Bandera, and Tintin, one of the five friends who build a riverside café after winning the jackpot in the lottery in La Belle Équipe with Jean Gabin and Charles Vanel. He also appeared in Duvivier’s Paquebot Tenacity and L’homme du jour. At IMDb, Guy Bellinger writes: “But even when he worked for less distinctive directors his presence was an asset for the film.” Some of these films now belong to the highlights of the Poetic realism, a French genre of the 1930s of lyrical, stylized and studio-bound films which offered a fatalistic view of life with their characters living on the margins of society, either as unemployed members of the working class or as criminals. Raymond Aimos was a courageous man in life. In August 1944, he decided to take part in the uprising against the Nazis which would lead to the Liberation of Paris. He was unfortunately hit by a stray bullet in the 10th Arrondissement. The exact circumstances of his death remain unclear and undetermined. He was only 53. Raymond Aimos never married and had no children. But he left an impressive film legacy, according to some sources he even appeared in nearly 450 films (IMDb only mentions 105 films)!

The tree was pruned back severely and replanted, with hopes it would survive.
Finally, a couple weeks ago, it began sprouting new growth.
It is tenacious, and obviously wants to live.

The bamboos (Bambusoideae) are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.
Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.
Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 88.9 Centimeters within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.
SYSTEMATICS AND TAXONOMY
The bamboos have long been considered the most primitive grasses, mostly because of the presence of bracteate, indeterminate inflorescences, "pseudospikelets", and flowers with three lodicules, six stamens, and three stigmas. Following more recent molecular phylogenetic research, many tribes and genera of grasses formerly included in Bambusoideae are now classified in other subfamilies, e.g. the Anomochlooideae, the Puelioideae, and the Ehrhartoideae. The subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae (bluegrasses and relatives).
The bamboos contains three clades classified as tribes, and these strongly correspond with geographic divisions, representing the New World herbaceous species (Olyreae), tropical woody bamboos (Bambuseae) and temperate woody bamboos (Arundinarieae). The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos. Altogether, there are more than 1,400 species in 115 genera.
Tribe Olyreae (herbaceous bamboos)
Tribe Bambuseae (tropical woody bamboos)
Tribe Arundinarieae (temperate woody bamboos)
DISTRIBUTION
Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic states south to Argentina and Chile, reaching their southernmost point at 47°S latitude. Continental Europe is not known to have any native species of bamboo.
Recently, some attempts have been made to grow bamboo on a commercial basis in the Great Lakes region of east-central Africa, especially in Rwanda. In the United States, several companies are growing, harvesting, and distributing species such as Phyllostachys nigra (Henon) and Phyllostachys edulis (Moso).
ECOLOGY
Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 250 cm in 24 hours. However, the growth rate is dependent on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 centimetre per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo can grow over 30 m tall, and be as large as 15–20 cm in diameter. However, the size range for mature bamboo is species dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4.6–12 metres, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.
Unlike all trees, individual bamboo stems, or culms, emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During these several months, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now considered a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm. Around 5–8 years later (species and climate dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboos have a wide range of hardiness depending on species and locale. Small or young specimens of an individual species will produce small culms initially. As the clump and its rhizome system mature, taller and larger culms will be produced each year until the plant approaches its particular species limits of height and diameter.
Many tropical bamboo species will die at or near freezing temperatures, while some of the hardier or so-called temperate bamboos can survive temperatures as low as −29 °C. Some of the hardiest bamboo species can be grown in places as cold as USDA Plant Hardiness Zones 5–6, although they typically will defoliate and may even lose all above-ground growth, yet the rhizomes will survive and send up shoots again the next spring. In milder climates, such as USDA Zone 8 and above, some hardy bamboo may remain fully leafed out year-round.
MASS FLOWERING
Most bamboo species flower infrequently. In fact, many bamboos only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular cohort flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 130 years, and it is for the species Phyllostachys bambusoides (Sieb. & Zucc.). In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies. The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth. This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.
One hypothesis to explain the evolution of this semelparous mass flowering is the predator satiation hypothesis which argues that by fruiting at the same time, a population increases the survival rate of their seeds by flooding the area with fruit, so, even if predators eat their fill, seeds will still be left over. By having a flowering cycle longer than the lifespan of the rodent predators, bamboos can regulate animal populations by causing starvation during the period between flowering events. Thus the death of the adult clone is due to resource exhaustion, as it would be more effective for parent plants to devote all resources to creating a large seed crop than to hold back energy for their own regeneration.
Another, the fire cycle hypothesis, argues that periodic flowering followed by death of the adult plants has evolved as a mechanism to create disturbance in the habitat, thus providing the seedlings with a gap in which to grow. This argues that the dead culms create a large fuel load, and also a large target for lightning strikes, increasing the likelihood of wildfire. Because bamboos can be aggressive as early successional plants, the seedlings would be able to outstrip other plants and take over the space left by their parents.
However, both have been disputed for different reasons. The predator satiation hypothesis does not explain why the flowering cycle is 10 times longer than the lifespan of the local rodents, something not predicted. The bamboo fire cycle hypothesis is considered by a few scientists to be unreasonable; they argue[20] that fires only result from humans and there is no natural fire in India. This notion is considered wrong based on distribution of lightning strike data during the dry season throughout India. However, another argument against this is the lack of precedent for any living organism to harness something as unpredictable as lightning strikes to increase its chance of survival as part of natural evolutionary progress.
More recently, a mathematical explanation for the extreme length of the flowering cycles has been offered, involving both the stabilizing selection implied by the predator satiation hypothesis and others, and the fact that plants that flower at longer intervals tend to release more seeds. The hypothesis claims that bamboo flowering intervals grew by integer multiplication. A mutant bamboo plant flowering at a non-integer multiple of its population's flowering interval would release its seeds alone, and would not enjoy the benefits of collective flowering (such as protection from predators). On the other hand, a mutant bamboo plant flowering at an integer multiple of its population's flowering interval would release its seeds only during collective flowering events, and would release more seeds than the average plant in the population. It could therefore take over the population, establishing a flowering interval that is an integer multiple of the previous flowering interval. The hypothesis predicts that observed bamboo flowering intervals should factorize into small prime numbers.
The mass fruiting also has direct economic and ecological consequences, however. The huge increase in available fruit in the forests often causes a boom in rodent populations, leading to increases in disease and famine in nearby human populations. For example, devastating consequences occur when the Melocanna bambusoides population flowers and fruits once every 30–35 years around the Bay of Bengal. The death of the bamboo plants following their fruiting means the local people lose their building material, and the large increase in bamboo fruit leads to a rapid increase in rodent populations. As the number of rodents increases, they consume all available food, including grain fields and stored food, sometimes leading to famine. These rats can also carry dangerous diseases, such as typhus, typhoid, and bubonic plague, which can reach epidemic proportions as the rodents increase in number. The relationship between rat populations and bamboo flowering was examined in a 2009 Nova documentary "Rat Attack".
In any case, flowering produces masses of seeds, typically suspended from the ends of the branches. These seeds will give rise to a new generation of plants that may be identical in appearance to those that preceded the flowering, or they may produce new cultivars with different characteristics, such as the presence or absence of striping or other changes in coloration of the culms.
Several bamboo species are never known to set seed even when sporadically flowering has been reported. Bambusa vulgaris, Bambusa balcooa and Dendrocalamus stocksii are common examples of such bamboo.
AS ANIMAL DIET
Soft bamboo shoots, stems, and leaves are the major food source of the giant panda of China, the red panda of Nepal and the bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain gorillas of Africa also feed on bamboo, and have been documented consuming bamboo sap which was fermented and alcoholic; chimpanzees and elephants of the region also eat the stalks.
The larvae of the bamboo borer (the moth Omphisa fuscidentalis) of Laos, Myanmar, Thailand and Yunnan Province, China, feeds off the pulp of live bamboo. In turn, these caterpillars are considered a local delicacy.
CULTIVATION
COMMERCIAL TIMBER
Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as "timber bamboos".
HARVESTING
Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the sap are at their lowest, as high sugar content increases the ease and rate of pest infestation.
Harvesting of bamboo is typically undertaken according to the following cycles:
1) Life cycle of the culm: As each individual culm goes through a 5– to 7-year life cycle, culms are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the life cycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.
2) Annual cycle: As all growth of new bamboo occurs during the wet season, disturbing the clump during this phase will potentially damage the upcoming crop. Also during this high rainfall period, sap levels are at their highest, and then diminish towards the dry season. Picking immediately prior to the wet/growth season may also damage new shoots. Hence, harvesting is best a few months prior to the start of the wet season.
3) Daily cycle: During the height of the day, photosynthesis is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest. Many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.
LEACHING
Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or postharvest photosynthesis.
EXEMPLES OF THIS PRACTICE INCLUDE:
Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.
A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.
Cut culms are immersed in a running stream and weighted down for three to four weeks.
Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).
In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.
Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain, will break down just as quickly as incorrectly harvested material.
ORNAMENTAL BAMBOOS
The two general patterns for the growth of bamboo are "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. "Running" bamboos, on the other hand, need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their roots and/or rhizomes, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the soil and climate conditions. Some can send out runners of several metres a year, while others can stay in the same general area for long periods. If neglected, over time they can cause problems by moving into adjacent areas.
Bamboos seldom and unpredictably flower, and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant will decline and often die entirely. Although there are always a few species of bamboo in flower at any given time, collectors desiring to grow specific bamboo typically obtain their plants as divisions of already-growing plants, rather than waiting for seeds to be produced.
Regular observations will indicate major growth directions and locations. Once the rhizomes are cut, they are typically removed; however, rhizomes take a number of months to mature, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the removed rhizome. The fibrous roots that radiate from the rhizomes do not produce more bamboo.
Bamboo growth is also controlled by surrounding the plant or grove with a physical barrier. Typically, concrete and specially rolled HDPE plastic are the materials used to create the barrier, which is placed in a 60– to 90-cm-deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. (This is only possible if the barrier is installed in a straight line.) If the containment area is small, this method can be detrimental to ornamental bamboo, as the bamboo within can become rootbound and start to display the signs of any unhealthy containerized plant. In addition, rhizomes can escape over the top, or beneath the barrier if it is not deep enough. Strong rhizomes and tools can penetrate plastic barriers, so care must be taken. In small areas, regular maintenance may be the best method for controlling the running bamboos. Barriers and edging are unnecessary for clump-forming bamboos, although these may eventually need to have portions removed if they become too large.
The ornamental plant sold in containers and marketed as "lucky bamboo" is actually an entirely unrelated plant, Dracaena sanderiana. It is a resilient member of the lily family that grows in the dark, tropical rainforests of Southeast Asia and Africa. Lucky bamboo has long been associated with the Eastern practice of feng shui and images of the plant widely available on the Web are often used to depict bamboo. On a similar note, Japanese knotweed is also sometimes mistaken for a bamboo, but it grows wild and is considered an invasive species. Phyllostachys species of bamboo are also considered invasive and illegal to sell or propagate in some areas of the US.
USES
CULINARY
Although the shoots (new culms that come out of the ground) of bamboo contain a toxin taxiphyllin (a cyanogenic glycoside) that produces cyanide in the gut, proper processing renders them edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions. The golden bamboo lemur ingests many times the quantity of the taxiphyllin-containing bamboo that would kill a human.
The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called khorisa. In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with turmeric and oil, and cooked with potatoes into a dish that usually accompanies rice (alu tama (आलु तामा) in Nepali).
In Indonesia, they are sliced thin and then boiled with santan (thick coconut milk) and spices to make a dish called gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia: fried wrapped bamboo shoots with vegetables). The shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.
Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots.
The sap of young stalks tapped during the rainy season may be fermented to make ulanzi (a sweet wine) or simply made into a soft drink. Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients.
Pickled bamboo shoots (Nepali:तामा tama) are cooked with black-eyed beans as a delicacy food in Nepal. Many Nepalese restaurant around the world serve this dish as aloo bodi tama. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winter months. Baby shoots (Nepali: tusa) of a very different variety of bamboo (Nepali: निगालो Nigalo) native to Nepal is cooked as a curry in Hilly regions.
In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare kardi. The name is derived from the Sanskrit word for bamboo shoot, karira. This fermented bamboo shoot is used in various culinary preparations, notably amil, a sour vegetable soup. It is also made into pancakes using rice flour as a binding agent. The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as hendua. It is also cooked with tender pumpkin leaves to make sag green leaves.
In Konkani cuisine, the tender shoots (kirlu) are grated and cooked with crushed jackfruit seeds to prepare 'kirla sukke'.
The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of Pu-erh tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.
In addition, bamboo is frequently used for cooking utensils within many cultures, and is used in the manufacture of chopsticks. In modern times, some see bamboo tools as an ecofriendly alternative to other manufactured utensils.
MEDICINE
Bamboo is used in Chinese medicine for treating infections and healing. In northern Indian state of Assam, the fermented bamboo paste known as khorisa is known locally as a folk remedy for the treatment of impotence, infertility, and menstrual pains.
CONSTRUCTION
Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.
In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.
Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong. In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.
Various structural shapes may be made by training the bamboo to assume them as it grows. Squared sections of bamboo are created by compressing the growing stalk within a square form. Arches may similarly be created by forcing the bamboo's growth into the desired form, costing much less than it would to obtain the same shape with regular wood timber. More traditional forming methods, such as the application of heat and pressure, may also be used to curve or flatten the cut stalks.
Bamboo can be cut and laminated into sheets and planks. This process involves cutting stalks into thin strips, planing them flat, and boiling and drying the strips; they are then glued, pressed and finished. Long used in China and Japan, entrepreneurs started developing and selling laminated bamboo flooring in the West during the mid-1990s; products made from bamboo laminate, including flooring, cabinetry, furniture and even decorations, are currently surging in popularity, transitioning from the boutique market to mainstream providers such as Home Depot. The bamboo goods industry (which also includes small goods, fabric, etc.) is expected to be worth $25 billion by 2012. The quality of bamboo laminate varies among manufacturers and varies according to the maturity of the plant from which it was harvested (six years being considered the optimum); the sturdiest products fulfill their claims of being up to three times harder than oak hardwood while others may be softer than standard hardwood.
Bamboo intended for use in construction should be treated to resist insects and rot. The most common solution for this purpose is a mixture of borax and boric acid. Another process involves boiling cut bamboo to remove the starches that attract insects.
Bamboo has been used as reinforcement for concrete in those areas where it is plentiful, though dispute exists over its effectiveness in the various studies done on the subject. Bamboo does have the necessary strength to fulfil this function, but untreated bamboo will swell with water absorbed from the concrete, causing it to crack. Several procedures must be followed to overcome this shortcoming.
Several institutes, businesses, and universities are researching the use of bamboo as an ecological construction material. In the United States and France, it is possible to get houses made entirely of bamboo,[citation needed] which are earthquake- and cyclone-resistant and internationally certified. In Bali, Indonesia, an international K-12 school, the Green School, is constructed entirely of bamboo, for its beauty and advantages as a sustainable resource. There are three ISO standards for bamboo as a construction material.
In parts of India, bamboo is used for drying clothes indoors, both as a rod high up near the ceiling to hang clothes on, and as a stick wielded with acquired expert skill to hoist, spread, and to take down the clothes when dry. It is also commonly used to make ladders, which apart from their normal function, are also used for carrying bodies in funerals. In Maharashtra, the bamboo groves and forests are called Veluvana, the name velu for bamboo is most likely from Sanskrit, while vana means forest.
Furthermore, bamboo is also used to create flagpoles for saffron-coloured, Hindu religious flags, which can be seen fluttering across India, especially in Bihar and Uttar Pradesh, as well as in Guyana and Suriname in South America.
Bamboo was used for the structural members of the India pavilion at Expo 2010 in Shanghai. The pavilion is the world’s largest bamboo dome, about 34 m in diameter, with bamboo beams/members overlaid with a ferro-concrete slab, waterproofing, copper plate, solar PV panels, a small windmill, and live plants. A total of 30 km of bamboo was used. The dome is supported on 18-m-long steel piles and a series of steel ring beams. The bamboo was treated with borax and boric acid as a fire retardant and insecticide and bent in the required shape. The bamboo sections were joined with reinforcement bars and concrete mortar to achieve the necessary lengths.
TEXTILES
Since the fibers of bamboo are very short (less than 3 mm), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only rayon made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include lye, carbon disulfide and strong acids. Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet; however, the Canadian Competition Bureau and the US Federal Trade Commission, as of mid-2009, are cracking down on the practice of labeling bamboo rayon as natural bamboo fabric. Under the guidelines of both agencies, these products must be labeled as rayon with the optional qualifier "from bamboo".
AS A WRITING SURFACE
Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. However, references in earlier texts surviving on other media make it clear that some precursor of these Warring States period bamboo slips was in use as early as the late Shang period (from about 1250 BC).
Bamboo or wooden strips were the standard writing material during the Han dynasty, and excavated examples have been found in abundance. Subsequently, paper began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China. Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production.
Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade paper is still produced in small quantities. Coarse bamboo paper is still used to make spirit money in many Chinese communities.
Bamboo pulps are mainly produced in China, Myanmar, Thailand and India, and are used in printing and writing papers. The most common bamboo species used for paper are Dendrocalamus asper and Bamboo bluemanea. It is also possible to make dissolving pulp from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to softwood pulps due to it having a very broad fiber length distribution. With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.[
WEAPONS
Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.
A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of silambam, a word derived from a term meaning "hill bamboo".
Staves used in the Indian martial art of gatka are commonly made from bamboo, a material favoured for its light weight.
A bamboo sword called a shinai is used in the Japanese martial art of kendo.
Bamboo is used for crafting the bows, called yumi, and arrows used in the Japanese martial art kyudo.
Bamboo is sometimes used to craft the limbs of the longbow and recurve bow used in traditional archery, and to make superior weapons for bowhunting and target archery.
The first gunpowder-based weapons, such as the fire lance, were made of bamboo.
Bamboo was apparently used in East and South Asia as a means of torture.
OTHER USES
Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).
Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.
Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.
Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater.
Food is cooked in East Timor in bamboo in fire. This is called Tukir.
Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 metres long, laid together side by side to a width of about 1 metre. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chop sticks, trays, and tea scoops.
The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan'an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.
SYMBOLISM AND CULTURE
Bamboo's long life makes it a Chinese symbol of uprightness, while in India it is a symbol of friendship. The rarity of its blossoming has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May 2006 (see Mautam). Bamboo is said to bloom in this manner only about every 50 years (see 28–60 year examples in FAO: 'gregarious' species table).
In Chinese culture, the bamboo, plum blossom, orchid, and chrysanthemum (often known as méi lán zhú jú 梅兰竹菊) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in Confucian ideology, four aspects of the junzi ("prince" or "noble one"). The pine (sōng 松), the bamboo (zhú 竹), and the plum blossom (méi 梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" (岁寒三友 suìhán sānyǒu) in Chinese culture. The "Three Friends of Winter" is traditionally used as a system of ranking in Japan, for example in sushi sets or accommodations at a traditional ryokan. Pine (matsu 松) is of the first rank, bamboo (také 竹) is of second rank, and plum (ume 梅) is of the third.
The Bozo ethnic group of West Africa take their name from the Bambara phrase bo-so, which means "bamboo house". Bamboo is also the national plant of St. Lucia.
BAMBOO, NOBLE AND USEFUL
Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and hollow heart, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. According to laws, an ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice. Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (sǔn筍 in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called "Sǔn Pǔ筍譜" offering descriptions and recipes for many kinds of bamboo shoots. Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China. In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.
In Japan, a bamboo forest sometimes surrounds a Shinto shrine as part of a sacred barrier against evil. Many Buddhist temples also have bamboo groves.
Bamboo plays an important part of the culture of Vietnam. Bamboo symbolizes the spirit of Vovinam (a Vietnamese martial arts): cương nhu phối triển (coordination between hard and soft (martial arts)). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity, and adaptability. A Vietnamese proverb says, "When the bamboo is old, the bamboo sprouts appear", the meaning being Vietnam will never be annihilated; if the previous generation dies, the children take their place. Therefore, the Vietnam nation and Vietnamese value will be maintained and developed eternally. Traditional Vietnamese villages are surrounded by thick bamboo hedges (lũy tre).
IN MYTHOLOGY
Several Asian cultures, including that of the Andaman Islands, believe humanity emerged from a bamboo stem.
In Philippine mythology, one of the more famous creation accounts tells of the first man, Malakás ("Strong"), and the first woman, Maganda ("Beautiful"), each emerged from one half of a split bamboo stem on an island formed after the battle between Sky and Ocean. In Malaysia, a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "Tale of the Bamboo Cutter" (Taketori Monogatari) tells of a princess from the Moon emerging from a shining bamboo section. Hawaiian bamboo ('ohe) is a kinolau or body form of the Polynesian creator god Kāne.
A bamboo cane is also the weapon of Vietnamese legendary hero, Saint Giong, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. An ancient Vietnamese legend (The Hundred-knot Bamboo Tree) tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "bamboo tree of 100 nodes". But Gautama Buddha (Bụt) appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. Bụt gave to him four magic words to attach the many nodes of bamboo: Khắc nhập, khắc xuất, which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.
In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. Later, Shun drowned in the Xiang River. The tears his two bereaved wives let fall upon the bamboos growing there explains the origin of spotted bamboo. The two women later became goddesses.
