Terrestrial Ecosystems

The need to measure and understand change in Arctic biodiversity is increasing given the evidence that  Arctic ecosystems are already rapidly responding, in some cases quite dramatically, to climatic changes. Substantial shifts in the Arctic environment are predicted for the near future (e.g., encroachment of more southerly species and ecosystems) and recent changes in physical processes such as sea ice loss have outpaced predicted changes. Limited functional redundancy in Arctic ecosystems poses a particular risk as the loss of a single species could have dramatic and cascading effects on an ecosystem’s state and function. (TEMG): Designing an Arctic Terrestrial Biodiversity Monitoring Plan Workshop)

In Russia, the main threat for the most productive post- Soviet reindeer herding areas in the Nenets and Yamalo- Nenets Autonomous Okrugs is the rapidly accelerating oil and gas extraction
reindeerherding siberia

A false color Quickbird-2 satellite image of a portion of the Bovanenkovo Gas Field on the Yamal Peninsula in West Siberia. Image acquired 4 July 2004. The construction phase began in the late 1980s. From that period onward there remain visible signs of extensive off-road vehicle traffic across the terrain. Many of those tracks have naturally revegetated and now appear as bright red, indicating dense grass- and sedge-dominated vegetation. The road network was built in the mid-1990s, which has reduced off-road traffic significantly. However, infrastructure blocks segments of migration routes for Nenets and their reindeer herds, and pasture quality can be negatively affected by road dust, petrochemicals, trash left on the tundra, and even feral dogs abandoned by workers.
