The use of Forest Service experimental forests and ranges for long-term research on invasive species

The 81 experimental forests and ranges (EFRs) research sites make the U.S. Department of Agriculture (USDA), Forest Service unique among land management agencies. The EFRs were established for conducting applied research that serves as a basis for managing forests and rangelands. Most EFR research sites have long histories of experimentation and research that provide current and future answers to questions concerning the effects of management activities and how to better achieve management goals. Most EFRs have served as focal points for education and demonstration projects and as venues for the interaction between scientists and land managers and for the training of graduate students in forestry and related sciences. Research on EFRs has and will continue to contribute to a better fundamental understanding of how ecosystems function.
