Executive Summary Lomatium cookii is endemic to southwestern Oregon, and is listed as endangered by the State of Oregon and by the U.S. Fish and Wildlife Service (USFWS). Populations discussed in this report are located in the Illinois Valley in Josephine County. Long-term monitoring has occurred at French Flat since 1990, at Rough and Ready […]
Executive Summary Lomatium cookii is endemic to southwestern Oregon with only two known populations in Jackson and Josephine Counties. The species is listed as endangered by the State of Oregon and the U.S. Fish and Wildlife Service, and the Draft Recovery Plan for the species identifies population augmentation and reintroduction as necessary steps toward recovery. […]
EXECUTIVE SUMMARY This document summarizes results from two studies involving habitat management techniques for L. cookii to support recovery of the species. The studies include 1) an evaluation of herbicide effects at Illinois Forks State Park, in areas occupied and unoccupied with L. cookii and 2) the effects of prescribed fire on L. cookii and […]
Baseline monitoring at the Wallooskee-Youngs restoration site, 2015, Part 2: Blue carbon, ecosystem drivers and biotic responsesLaura S. Brophy, Laura A. Brown, Michael J. Ewald, and Erin K. Peck 2018
EXECUTIVE SUMMARY: The goals of this project are to increase existing native plant populations and diversity at this site and decrease invasive species populations. In 2017 restoration activities included mechanical removal of small patches of invasive species within the meadow and removal of small trees and limbing of larger trees within and along the meadow edges. […]
Astragalus mulfordiae: Population dynamics and the effect of cattle grazing in the Vale District, BLMPetix, Meaghan I., Erin C. Gray, and Matt A. Bahm 2017
EXECUTIVE SUMMARY This document summarizes monitoring of Astragalus mulfordiae (Mulford’s milkvetch) on land managed by the BLM Vale District. In 2017, we monitored plots testing for effects of herbivory on A. mulfordiae in permanent plots along with transects monitoring long-term population trends and plant community composition. In 2017 we observed an increase in number of […]
Executive Summary This report documents monitoring conducted on population characteristics and habitat of Kincaid’s lupine (Lupinus oreganus), a threatened species, and Hitchcock’s blue-eyed grass (Sisyrinchium hitchcockii), a federal species of concern, at Oak Basin. Kincaid’s lupine serves as the primary larval host plant for the endangered Fender’s blue butterfly (Icaricia icarioides fenderi). Both species are […]
Executive Summary Pink sand-verbena (Abronia umbellata ssp. breviflora) is listed as endangered by the Oregon Department of Agriculture, and a Species of Concern by the U.S. Fish and Wildlife Service. Since the late 1970’s, the number of natural populations in Oregon has decreased from approximately 10 populations to less than 5. The primary threats to […]
EXECUTIVE SUMMARY This document reports initial work from seed collection, propagation, and outplanting of Lupinus oreganus for the Roseburg District Bureau of Land Management. Sites managed by the Roseburg BLM represent the southernmost range of this threatened plant species. Three sites were outplanted including Callahan Meadows (approx. 1,900 plants), Loose Laces (approx. 1,075 plants), and […]
