R. Kasten Dumroese, Ph.D.
Plant Physiologist
National Nursery Specialist
USDA Forest Service
Rocky Mountain Research Station
1221 South Main Street
Moscow, ID 83843
Background
Kas spent the first 17 years of his career working at the University of Idaho research nursery. This facility is the "state nursery" operated by a university, offering unique opportunities to merge basic research with applied technology for nursery managers. In 2001 he joined the Forest Service. Although his office has always been in Moscow, Idaho, he worked for the Southern Research Station (Pineville, Louisiana) and the National Agroforestry Center (Lincoln, Nebraska) before becoming part of the Rocky Mountain Research Station's Grasslands, Shrublands, and Desert Ecosystem Program in fall 2008.He serves as National Nursery Specialist on the Agency's National Reforestation, Nurseries, and Genetics Resources (RNGR) team, an intra-Agency group focused on transferring technology. His responsibilities include publishing the National Nursery Proceedings and the Forest Nursery Notes newsletter, as well as coordinating administrative studies and other tasks.
Research Interests
Kas' research interests include all aspects of propagating native plants. He has published significant work on mitigating root diseases in nurseries, efficacy of subirrigation and use of exponential fertilization to reduce water pollution from nurseries, and seedling quality.Current Research and Projects
Dumroese initiated the Native Plants Journal in 2000 and continues to serve as editor in chief. The journal is devoted to the growing and planting of native plants. That same year he also initiated the Native Plant Network, an on-line database of native plant propagation protocols (see both at http://www.nativeplantnetwork.org). Kas is currently working to finish Volume 7 of Agriculture Handbook 674 (The Container Tree Nursery Manual) and Volume 2 of Agriculture Handbook 730 (Nursery Manual For Native Plants: A Guide For Tribal Nurseries), and conducting work on optimum fertilizer regimes for longleaf pine seedlings, subirrigation of koa on Hawaii, sagebrush and aspen propagation, and using waste biochar as a substrate amendment for container seedlings.Recent Recognition
