This dataset portrays the viability score (scale of 0 - 1.0) for Pacific silver fir (Abies amabilis) in western North America in 2060, using the Canadian Center of Climate Modeling and Analysis (CGCM3) general circulation model (GCM) and A2 emission scenario (high emissions, regionally diverse world, rapid growth) to model future climate. (From Crookston et al. 2010): To develop the climate profile, we used a data from permanent sample plots largely from Forest Inventory and Analysis (FIA, Bechtold and Patterson, 2005) but supplemented with research plot data to provide about 117,000 observations (see Rehfeldt et al., 2006, 2009) describing the presence and absence of numerous species. The Random Forests classification...

This dataset portrays the viability score (scale of 0 - 1.0) for Douglas fir (Pseudotsuga menziesii) in western North America in 2090, using the Canadian Center of Climate Modeling and Analysis (CGCM3) general circulation model (GCM) and A2 emission scenario (high emissions, regionally diverse world, rapid growth) to model future climate.

This dataset portrays the "current" (2010) viability score (scale of 0 - 1.0) for Coast live oak (Quercus agrifolia) in western North America. It serves as the base condition for future species-climate profiles. (From Crookston et al. 2010): To develop the climate profile, we used a data from permanent sample plots largely from Forest Inventory and Analysis (FIA, Bechtold and Patterson, 2005) but supplemented with research plot data to provide about 117,000 observations (see Rehfeldt et al., 2006, 2009) describing the presence and absence of numerous species. The Random Forests classification tree of Breiman (2001), implemented in R by Liaw and Wiener (2002), was then used to predict the presence or absence of...
