Increasing aridity is forcing some treelines uphill

Factsheet/brief icon

View research brief.

Lower treelines in the Intermountain West are often defined by the boundary beyond which conditions are too dry for trees. Scientists are observing tree mortality in response to global climate changes and associated increased aridity in some places. Land managers are keenly interested in these changing ecological dynamics and how forests will shift in response to climate change.
