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

Giles, D.E.L. and T.N. Kaye   2018

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, though the current status of populations […]

Assessing management techniques for Lomatium cookii

Giles, D.E.L., E.C. Gray, and M.A. Bahm   2015

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 the surrounding […]

Rare plant monitoring in the Lakeview Resource Area

Petix, M.I., M.A. Bahm, A.L. Schomaker, and D.E.L Giles   2018

During the spring and summer of 2018, we monitored 18 plant species (15 vascular, three non-vascular) listed as special status species (SSS) in the Bureau of Land Management’s (BLM) Lakeview Resource Area. Approximately 2,000 acres were surveyed and 12 of the 18 target species were observed over the survey period stretching from April 11th to June 26th.

Seed germination of Peck’s penstemon

Peck’s penstemon (Penstemon peckii) is endemic to Oregon, occurring in only Deschutes and Jefferson counties.  It is considered a Sensitive Species by the US Forest Service, and a Species of Concern by the US Fish and Wildlife Service.  Most of its known occurrences are on the Deschutes National Forest. Previous research on the germination of […]

Astragalus mulfordiae: Population dynamics and the effect of cattle grazing in the Vale District, BLM

Schomaker, A. Lisa and Matt A. Bahm   2018

EXECUTIVE SUMMARY This document summarizes the monitoring of Astragalus mulfordiae (Mulford’s milkvetch) on land managed by the BLM Vale District. In 2018, we revisited permanent plots testing for the effects of herbivory on A. mulfordiae, along with permanent transects looking at long-term population trends and plant community composition in A. mulfordiae habitat. •In 2018 we […]

Threat assessment for Limnanthes pumila ssp. pumila (dwarf woolly meadowfoam) on Table Rocks ACEC

Schomaker, A. Lisa and Matt A. Bahm   2018

EXECUTIVE SUMMARY Upper and Lower Table Rocks, located northeast of Medford, Oregon, are collectively designated as an Area of Critical Environmental Concern (ACEC) by the Bureau of Land Management (BLM). The Table Rocks are characterized primarily by vernal pool and mound habitats that support several rare species. Since 2006, the Institute for Applied Ecology (IAE) […]

Assessing management techniques for Lomatium cookii (Cook’s desert-parsley)

Giles, Denise E.L., Erin C. Gray, and Matt A. Bahm   2017

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 […]

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 […]

Propagation and reintroduction for Lupinus oreganus in the BLM, Roseburg District

Giles, Denise E.L. and Matt A. Bahm   2017

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 […]

Lupinus oreganus in the BLM Roseburg District: Population monitoring and restoration

Giles, Denise E.L. and Matt A. Bahm   2017

EXECUTIVE SUMMARY In 2017, we monitored L. oreganus populations by assessing foliar (leaf) cover (a measure of abundance), raceme count, and fruit production at five different sites in the Roseburg BLM District. Foliar cover and raceme count increased from 2016 values at all sites monitored in 2017. Seed set increased at all sites, except Loose […]

Habitat and population monitoring for Chloropyron maritimum ssp. palustre and Limonium californicum on the Coos Bay North Spit

Denise E.L. Giles, Erin C. Gray, Matt A. Bahm, and Thomas N. Kaye   2017

In 2017 the estimated number of Chloropyron maritimum ssp. palustre plants on the Coos Bay North Spit land managed by the Coos Bay District of the Bureau of Land Management is ~570,000, an increase from 2016 values.

In 2017 the population of Limonium californicum decreased from those observed in 2016, and is estimated to be ~564,000.

Habitat mapping from 2011-2017 has shown a shift towards more Limonium californicum dominant habitat types, and an increase in the non-native Juncus gerardii in recent years.
