Here is what we are working on:

• Modifying growth and yield of genetically improved Douglas-fir trees and stands in ORGANON and CIPSANON.
   
• Representing differential growth among Douglas-fir families by using heritable traits as predictor variables.
   
• Modeling soil and climatic mechanisms driving Douglas-fir tree and stand growth.
   
• Refining empirical modifiers for direct thinning effects on Douglas-fir height and diameter growth in ORGANON and CIPSANON.
   
• Modeling soil and climatic mechanisms driving Douglas-fir growth responses to thinning and fertilization.
   
• Refining empirical modifiers for direct fertilization effects on Douglas-fir height and diameter growth in ORGANON and CIPSANON.
   
• Approaches to simulating dynamics of competing vegetation in Douglas-fir growth models (CIPSANON).
   
• Revising diameter growth, height growth, and mortality equations for red alder plantation growth models.
   
• Developing diameter growth, height growth, and mortality equations for western hemlock stands.
