Shaping the science on beaver expansion

Arctic Beavers Reshape Tundra Ecosystems Amid Climate Shift Beavers are rapidly expanding northward into Arctic permafrost and tundra regions due to environmental change, fundamentally altering landscapes through dam construction. This expansion threatens traditional subsistence fishing practices as beavers dam creeks that indigenous communities rely on. Scientists are studying the ecological and social consequences of this species range shift in vulnerable Arctic regions.
