Abstract	Subalpine tree species and forest communities are assumed to respond to rising temperatures by migrating upslope. This generates a conservation hypothesis that habitat will be lost as area diminishes approaching mountain summits (“elevational squeeze”). Our prior studies of Great Basin forests and historic climate lead us to hypothesize that responses are more complex, with species following individualistic and often surprising paths. We began a study to investigate the effect of ongoing climate change on subalpine limber pine (Pinus flexilis; PiFl) populations in the Great Basin. Here we present results from the White Mtns portion of that study. In this range, bristlecone pine (P. longaeva; PiLo) currently and historically dominates the highest elevations and on dolomite soils (Fig. 1), PiFl occupies the middle subalpine range on non-dolomitic soils (Fig. 2), while singleleaf pinyon pine (P. monophylla; PiMn) historically occurred disjunctly below the other conifers (Fig. 3).
