Fires in the tundra can drastically alter vegetation and ecosystem characteristics. Drs. Hollingsworth and Breen (from the U.S. Forest Service and University of Alaska-Fairbanks, respectively) review the effects of climate on fire regime and wildfire in Alaska. They compare fire in the boreal forest to tundra and discuss what is known and what we are learning about tundra fires in Alaska. The Seward Peninsula is a good experimental system to understand future states of more northern tundra systems.
