The sky island forests of the southwestern United States are one of the most diverse temperate forest ecosystems in the world, providing key habitat for migrating and residential species alike. Black bear, bighorn sheep, mule deer, and wild turkey are just a few of the species found in these isolated mountain ecosystems that rise out of the desert landscape. However, recent droughts have crippled these ecosystems, causing significant tree death. Climate predictions suggest that this region will only face hotter and drier conditions in the future, potentially stressing these ecosystems even further. Simple models predict that vegetation will move to cooler and wetter locations in response to this warming. However,...

Wildfire refugia are forest patches that are minimally-impacted by fire and provide critical habitats for fire-sensitive species and seed sources for post-fire forest regeneration. Wildfire refugia are relatively understudied, particularly concerning the impacts of subsequent fires on existing refugia. We opportunistically re-visited 122 sites classified in 1994 for a prior fire refugia study, which were burned by two wildfires in 2012 in the Cascade mountains of central Washington, USA. We evaluated the fire effects for historically persistent fire refugia and compared them to the surrounding non-refugial forest matrix. Of 122 total refugial (43 plots) and non-refugial (79 plots) sites sampled following the 2012...

Climate summary variables reconstructed in high resolution for past and projected futures. We took detailed microclimate measurements across three mountain ranges in West Texas to identify key topographical drivers of microclimate variation, and modeled future fine scale climate as a function of topography and projected regional weather across multiple future scenarios.

Topographic predictors of local microclimate that that were derived from ASTER 30-m resolution digital elevation model (DEM) data from gdex.cr.usgs.gov/gdex/ and clipped to selected 12-digit hydrologic units that included ibutton sensor locations and adjacent hydrologic units in each mountain range.
