Book Description
Ecological site classification can be subjective, and attempts have been made throughout Canada to develop computer models for the consistent classification of plots. This report describes the application of fuzzy logic technology to ecological land classification data. In this research, investigators translated into a simple fuzzy logic program a classification of the forested portion of the montane subregion of west central Alberta by plant community type (a more detailed level than ecosite). The program was tested, using the FuzzyTECH fuzzy logic software package, on 147 ecological site information system plots compiled by Alberta Environment. The results compare the computerized classification with that of experts, and reasons for discrepancies are identified.

Book Description
One hundred thirty forests stands ranging in age from 1 month postfire to 200 years were sampled and described by successional series (white spruce and black spruce) and by developmental stage (newly burned, moss-herb, tall shrub-sapling, dense tree, hardwood, and spruce). Patterns of change in the two successional series are described. In addition, 12 mature forest communities are described in quantitative and qualitative terms.

Book Description
A classification of bunchgrass vegetation is presented for the Malheur, Ochoco, Umatilla, and part of the Wallowa-Whitman National Forests. It includes grassland vegetation as well as shrubland and forest land where the herbaceous layer is dominated by bunchgrasses. It is based on potential vegetation, with the plant association as the basic unit. Diagnostic keys and descriptions are presented for each type. Descriptions include information about plant species occurrence, environment and soils, states and transitions, forage productivity, management considerations, and relationships to other classifications.
