The need for more information about the autecology of major species of competing vegetation in British Columbia was identified by Conard (1984) in a problem analysis of vegetation management research needs in this province.
Most foresters are already familiar with the subject of autecology as it relates to tree species, but they usually use the term silvics. The two terms are synonymous except that autecology does not limit itself to tree species.
Thirty-one species are included in this publication. They include hardwood trees, shrubs, and some herbaceous plants. Some of the species are widely distributed and compete with coniferous tree growth throughout British Columbia, while others create only localized silvicultural problems. The list, compiled with assistance from Regional silviculturists and ecologists, includes major competing species from all Forest Regions, but emphasizes species that are a concern in the northern and interior areas of the province.
