Abstract

A general background on functional groups of invertebrates in the Columbia River basin and how they affect sustainability and productivity of their ecological communities is presented. The functional groups include detritivores, predators, pollinators, and grassland and forest herbivores. Invertebrate biodiversity and species of conservation interest are discussed. Effects of management practices on wildlands and suggestions to mitigate them are presented. Recommendations for further research and monitoring are given.

Keywords
