Biomass distributions in dwarf tree, krummholz, and tundra vegetation in the alpine treeline ecotone
Alpine treeline ecotones are expected to respond to climate change with shifts in biomass patterns and carbon dynamics; however, the nature of these shifts and the current structure of carbon storage at treeline remain poorly understood. Biomass at treeline sites in Glacier National Park (GNP), Mont...
