Taylor’s checkerspot butterfly habitat restoration at Cardwell Hill: Final Report 2019

Andy Neill   2019

The Institute for Applied Ecology worked with private landowners and USFWS Partners for Fish and Wildlife Program to enhance the three Taylor’s checkerspot butterfly occupied meadows at Cardwell Hill during 2018 and 2019. Work was funded by a grant with Oregon Watershed Enhancement Board funds administered through the Oregon State Weed Board. This grant supported herbicide treatments to control priority weeds and encroaching shrubs and the purchase and planting of plant materials to enhance and improve butterfly habitat throughout the Cardwell Hill project site.

Restoration of Willamette Valley Upland Prairies at Fern Ridge Reservoir

Gray, Erin C. and Matt A. Bahm   2018

Executive Summary This document summarizes long-term monitoring and provides management recommendations for prairie restoration efforts at Fern Ridge Reservoir on lands managed by the US Army Corps of Engineers.  Quantitative and/or qualitative monitoring has occurred annually since 2008, dependent upon whether treatment actions have occurred.  In 2018, we quantitatively monitored 9 sites: Big Spires, West […]

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 […]

Controlling exotic grasses while maintaining native plant communities in fire-maintained wet prairies

Schomaker, A.L., M.A. Bahm, and E.C. Gray   2019

The treatments tested in this study show potential for addressing a subset of restoration goals within the Fern Ridge RNA (reducing Anthoxanthum odoratum cover, increasing native species cover, and decreasing exotic species cover). Currently, no individual treatment provides desired results in all of the measured variables but a combination of the strategies tested here may […]

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

Kaye, Thomas N. and Matt A. Bahm   2018

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 […]
