Description: Continuous scale from 0 (extremely infertile) to 1.0 (no nutrient limitations) derived from inverting 3-PG model to predict canopy leaf area index, with the assumption that drought -prone sites with max LAI <3.0 m2/m2 would generally have lower values of soil fertility than sites where max LAI was >3.0.

Professor emeritus with Oregon State University

My early work dealt with describing the distribution and growth of forest vegetation in relation to measured environmental gradients. In the 1980s, my interest turned toward ecosystems. More recently, my research has focused on modeling forest growth and biodiversity under changing climates, along...
