This electronic newsletter (Invasive Species Science Update) is published by the Rocky Mountain Research Station (RMRS) Cross-Program, Interdisciplinary Project team on Invasive Species. This newsletter will be published 3 times per year and is intended to enhance communication among RMRS scientists, wildland managers, other partners, stakeholders, and customers about predicting, detecting, and monitoring invasive species in forest, rangeland, and aquatic ecosystems. Contributions for the newsletter are welcome from everyone involved in the ecology and management of any invasive species. We are specifically interested in emerging research and management issues (Science Notes), technology transfer programs (Outreach Activities and Ask The Expert), and noteworthy technical and non-technical publications (Publication News). Please submit contributions and suggestions for improving this newsletter to Mee-Sook Kim (Coordinator) or Jack Butler (Newsletter Editor).
