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, BLM

Petix, 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 […]

Population and habitat monitoring for Kincaid’s lupine and Hitchcock’s blue-eyed grass at Oak Basin

Giles, Denise E.L., Meaghan I. Petix, and Matt A. Bahm   2017

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 […]

Abronia umbellata ssp. breviflora on the Oregon coast: reintroduction and population monitoring

Giles, Denise E.L. and Thomas N. Kaye   2017

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.
