Krummholz and patch forest vegetation are studied at several sites on the east side of the Continental Divide in Glacier National Park, Montana, USA. The location of each sampled krummholz patch was collected as well as species information and a number of patch geometry measurements. Additionally, the Leaf Area Index (LAI) was derived for each patch using a LI-COR LAI-2000 plant canopy analyzer. The patch geometry information was used to create 3D models of each krummholz patch that, in turn, were used to derive two additional canopy structure variables, foliage density (FD) and drip-line LAI (DLLAI). Correlations were calculated among the canopy structure variables, patch position variables, landscape position variables, and biophysical variables. Results suggest (a) a complex internal patch organization of krummholz forest patches with respect to canopy structure, (b) canopy distribution strongly related to the slope position of the patch, and (c) a pronounced relationship between canopy structure, soil moisture potential, and landforms.
