We are studying treeline, the
ecotone between taiga (boreal forest) and tundra. What is the impact
of climate change on treeline?
We want to answer three
Has warming in the last 100 years caused
treeline to expand northward or uphill?
How has the growth rate and the shape of
trees at treeline changed?
How do climate and disturbance interact
together to affect treeline?
