This project explored improvements in modeling in the areas of site productivity potential, enhanced predictive site classification, and boreal mixed-wood succession. Specifically, the project focused on improving the accuracy of predictive forest ecosystems (ecosites) classification maps linked to management constraints and opportunities, in addition to assessing potential versus actual productivity of the mapped units. Boreal mixed wood succession modeling was not completed under this project due to the passing of the project lead. The project was incorporated as part of a larger program with the Canadian Forest Service as part of the Landscape Management Project. The Canadian Forest Service provided three reports describing project developments. Two reports addressed work done on modeling site productivity. The first is entitled, “Spatial Mapping and Modelling within the Weyerhaeuser Canada FMA’s in West Central Alberta – Landscape Management Network” by Corns et al., and the second entitled, “Spatial Modeling of Lodgepole Pine Site Productivity in Alberta Upper Foothills” by Richard C. Yang and Ian Corns. They describe the process used to predict and map site productivity potential using geographic data sets available to forest managers. The third report addressed the topic of predictive ecosite classification. The report is entitled, “Ecosystem Mapping in the Lower Foothills Subregion of Alberta: Application of Fuzzy Logic” by L.B Nadeau, C. Li and H. Hans. This project demonstrated and documented how vague logic computer programs can be used to classify and map ecosites.
