Distribution and observed trends of wild Rangifer populations throughout the circumpolar Arctic (from The Circum Arctic Rangifer Monitoring and Assessment Network, CARMA). Currently wild reindeer and caribou have declined by about 33% since populations (herds) peaked in the 1990s and early 2000s (3.8 million compared to 5.6 million) which followed almost universal increases in the 1970s and 1980s. In Arctic Eurasia reindeer herding represents a livelihood and cultural tradition of indigenous peoples, such as the Sami in Arctic Europe. Note: Wild boreal forest reindeer have not been mapped by CARMA and thus are not represented here.

Among the many impacts erosion has on coastal ecosystems are the destruction of soil surface layers, leading to groundwater pollution and to reduction of water resources; degradation of dunes, leading to desertification; reduction of biological diversity; adverse effects on beach dynamics; reduction of sedimentary resources; and disappearance of the sandy littoral lanes that protect agricultural land from the intrusion of seawater, resulting in soil and groundwater salinisation (EEA and UNEP 2006).

n April 23, BLM Range Management Specialists shot photos and video at a Sage-grouse lek near Louse Canyon geographic management area and McDermitt, Oregon.
The sagebrush ecosystem is home to unique plant and wildlife species, and is very important to the overall ecological health of eastern Oregon. Many birds and mammals depend on sagebrush ecosystems in the western United States for survival. In the last century, drastic changes caused by livestock grazing, conversion of lands to agriculture, the introduction of exotic plant species, and fire have resulted in alteration and fragmentation of sagebrush vegetative communities throughout the Intermountain West. The loss of sagebrush ecosystems are negatively affecting many of the more than 350 species of plants and animals that depend on sagebrush ecosystems for all or part of their existence including Greater Sage-Grouse as well as Pygmy Rabbit, Mule Deer, and Golden Eagles. Other examples of sagebrush dependent species include sage sparrow, ferruginous hawks, Brewer's sparrow, sage thrasher, sagebrush vole, and many botanical species.
Over the last several years, in response to requests from state and local governments to facilitate ways to conserve Greater Sage-Grouse and protect its habitat, BLM scientists and managers met with state wildlife management officials. The BLM strategy emphasizes a cooperative approach and provides a framework to advance efforts to implement timely conservation measures for sage-grouse and its habitat.

This is a promienent relief feature. The sand here is more stable and contains some humus. Almost all marram grass. The growth of the marram grass slows the wind speed and reduces sand movement.
In an ecosystem both abiotic and biotic factors are included. Here at Sotol Vista you can see the vegetation and rock background.

Napier grass is planted to prevent soil erosion in the Kenya's Tana River Basin. Here a landslide has destroyed one farm. The Tana River watershed is Kenya's life blood. CIAT and partners are exploring ecosystems trade-offs to benefit both the environment and improve farmer incomes and livelihoods. Read the full story here: bit.ly/11xEk3F

The Denali National Park is located in Interior Alaska and contains Denali (Mount McKinley), with 6,194 m the highest mountain in North America. The national park and preserve is over 24,500 km, of which 19,120 km are federally owned. The national preserve is 5,430 km, of which 5,278 km are federally owned. On December 2, 1980, a 8,687 km Denali Wilderness was established within the park. Denali habitat is a mix of forest at the lowest elevations, including deciduous taiga. The preserve is also home to tundra at middle elevations, and glaciers, rock, and snow at the highest elevations. The longest glacier is the Kahiltna Glacier. Today, the park hosts more than 400,000 visitors who enjoy wildlife viewing, mountaineering, and backpacking.

Well, here's something you don't see every day. While walking in a wooded area, I came upon this lost sneaker, whose canvas is happily supporting a nice ecosystem of moss. At least this abandoned shoe isn't just trash.

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 cause various consequences such as melting sea ice and a rising and warming sea level, which in turn has a significant effect on the natural ecosystem. This is already seen in the appearance of shrubbery in Arctic climates, northern movement of animals from the South and influx of invasive species and diseases, with the implications most felt in coastal areas.

This colorful painted bunting was among a wide variety of birds spotted in a wildlife survey at the site of the Sam Jones/Abiaki Prairie C-139 Annex Restoration Project.
The project will restore 15,000 acres of former citrus grove back to Everglades habitat, featuring an expansive wet prairie system with scattered cypress domes, tree island hammocks and sloughs. The SFWMD Governing Board approved the start of restoration work in December 2015. Read more about the project in this news release.

in the opinion of John Grehan a leading authority on Hepialidae this is a undescibed species of Endoclita.Hopefully i get to see it again and collect it for further investigation.
