The mission of the Policy Analysis Center for Western Public Lands is to help rural communities, policy makers, resource managers and users, and others understand, analyze and engage effectively in the public land policy process. The Center will provide relevant, science-based information and analysis of ongoing and proposed public land management policies.
BACKGROUND AND AIMS Lomatium dissectum (Apiaceae) is a perennial, herbaceous plant of wide distribution in Western North America. At the time of dispersal, L. dissectum seeds are dormant and have under-developed embryos. The aims of this work were to determine the requirements for dormancy break and germination, to characterize the type of seed dormancy,(More)
He received a B.S. degree in agriculture from the University of Nebraska, an M.S. degree in range management, and a Ph.D. degree in botany (plant ecology) from Colorado State University. He joined the Forest Service in 1960 and conducted research on rangelands in Arizona, Louisiana, and Utah. More recently he has focused on riparian-livestock grazing issues(More)
Annual grass invasion in the Great Basin has increased fire size, frequency and severity. Post-fire restoration to provide functional native plant communities is critical to improve resistance to weed invasion. Our ability to successfully re-establish mixtures of native grasses, forbs and shrubs, however, is limited. We examined the effects of the standard(More)
A genecological approach was used to explore genetic variation in adaptive traits in Pseudoroegneria spicata, a key restoration grass, in the intermountain western United States. Common garden experiments were established at three contrasting sites with seedlings from two maternal parents from each of 114 populations along with five commercial releases(More)
