Book Description
This prototype model consists of a temperature regime ordinate, a moisture regime ordinate, and a regression equation relating them to aspen site index in the Southern Rocky Mountains. Its construction required a close look at a number of problems and considerations, and some possible methods, in ecosystem modeling. Clonal variation in aspen hight growth prevented a good test of the model, however. The temperature regime ordinate is analogous to degree-days, and integrates elevation and latitude within subregions. The moisture regime ordinate integrates estimates of monthly precipitation, monthly mean temperatures, potential direct-beam insolation, water-holding capacity of the soil, and factors influencing runoff. Equations are provided for estimating mean monthly precipitation, based on topographic and other factors.

Book Description
Information about the biology, ecology, and management of quaking aspen on the mountains and plateaus of the interior western United States, and to a lesser extent, Canada, is summarized and discussed. The biology of aspen as a tree species, community relationships in the aspen ecosystem, environments, and factors affecting aspen forests are reviewed. The resources available within and from the aspen forest type, and their past and potential uses are examined. Silvicultural methods and other approaches to managing aspen for various resources and uses are presented.
