Abstract

Current understanding of treeline or forest-alpine ecotone (FAE) dynamics does not fully explain past and
present FAE patterns and their underlying processes, nor allow prediction of their response to climate change.
We address the overarching hypothesis that the FAE is a mosaic of distinct landscape units of vegetation and
landforms that result in differential responses to climate change. We focus on climate-related, landscape and vegetation
characteristics, but also consider the effect of landscape heterogeneity on biogeochemistry and overall resilience of the FAE
to climate change.
