MELINDA MOEUR received her master's degree in forestry 

 from the University of Minnesota in 1980. As a research 

 forester at the Forestry Sciences Laboratory, Moscow, Idaho, 

 she has worked on linking vegetation, watershed, and wildlife 

 system models into a decision-support system. 



RESEARCH SUMMARY 



Equations were derived for predicting crown width of trees 

 from diameter, height, crown length, and basal area per acre, 

 and for predicting foliage weight of trees from diameter, height, 

 crown length, age, relative diameter, and number of trees per 

 acre. Coefficients were estimated for 1 1 conifer species in 

 northern Idaho and western Montana. Embedding these equa- 

 tions in the prognosis model for stand development will en- 

 hance the prediction of vegetation characteristics needed for 

 interfacing insect outbreak, wildlife habitat, and watershed 

 models.
