| Summary: | Beaver engineering has rapidly increased in arctic tundra regions of Alaska. Ken Tape, Ben Jones, Jason Clark, and others are researching the patterns of beaver colonization and engineering in northern and western Alaska using satellite imagery and older aerial photography. These data describe formation of beaver ponds since 1950. The science team is also conducting field studies to understanding the impacts of beaver engineering on permafrost, the physical environment, and 'downstream' biological consequences to fish and stream productivity.
