Geomorphic controls of spatial pattern and process at alpine treeline

Auteur :
RESLER, L.M.

Description :
The aim of this study is to propose a conceptual model that describes the multi-spatial-scale relationship between treeline advance and geomorphology. The approach examines the spatial patterns of tree occurrence in Glacier National Park, Montana, at 3 spatial scales to establish the relative roles of macro- (landscape scale), meso- (aspect and elevation), and microscale (level of individual tree growth, establishment, and death) controls on tree establishment at the highest locations of alpine treeline. Geomorphic features are therefore important in linking scales of pattern and process at the alpine treeline ecotone.
