2. Materials and methods
This study utilized field data to drive a climate-sensitive
growth-and-yield model to project species-specific growth as a
function of down-scaled climate projections from four different
GCMs under two different emissions scenarios. The modeling
approach used differs from climate-only approaches by incorporating
biotic influences on tree growth, specifically competition. It
also differs from the approach of Crookston et al. (2010) by directly
incorporating climate projections, as opposed to representing
changes in climate through changes in site index.
