Seed Production and Establishment of Western Oregon Native Grasses
It is well understood that native grasses are ecologically important and provide numerous benefits. However, unfavorable economics, low seed yields for some species, genetic issues, and a lack of experience behind the production and establishment of most western Oregon native grasses remain significant impediments for their expanded use. By necessity, adaptation of standard practices used by the grass seed industry and grassland specialists for introduced species provides the starting point for determining agronomic increase and establishment methods. The USDA Natural Resources Conservation Service, Plant Materials Center at Corvallis, Oregon, has experience increasing at least 15 species of native grasses. It has also conducted studies involving the effects of fertilization, row spacing, post-harvest residue management (burning versus baling), and herbicides on yields of select species. Results are usually species specific, indicating much more research is needed. Fortunately for some native grasses, practical experience has demonstrated the efficacy of certain customary techniques such as carbon banding, timely fertilization, pesticide use, and windrow-combining. Specialty equipment for small grain, seed increase, and processing can be directly transferred or modified for use on native grasses.
