The Tundra Biome Program aims to understand cold-dominated ecosystems like tundra and taiga. They want to predict how the wet arctic tundra works, gather data on different cold ecosystems in the US, and apply this knowledge to protect these fragile environments. The researchers focus on the Barrow, Alaska area to study tundra. They also compare their findings with studies from other countries. The goal is to help with the conservation and restoration of these cold ecosystems.
