In tundra areas of Alaska, we need to be able to ascertain that enough old-growth lichen-rich habitats remain for our caribou herds and that habitat diversity is maintained. Examination of long-term range monitoring transects previously deployed in remote tundra areas of Alaska on BLM lands show significant declines in available caribou forage lichens (which are highly sensitive to disturbance and slow-growing) for caribou and reindeer. Post-fire recovery of lichens may be prolonged or questionable under current climate conditions. The principal objective is to determine the magnitude of climate change impacts to tundra and boreal forest fire regime.
