Insights into estuary habitat loss in the western United States using a new method for mapping maximum extent of tidal wetlandsBrophy, L.S., C.M. Greene, V.C. Hare, B. Holycross, A. Lanier, W.N. Heady, K. O'Connor, H. Imaki, T. Haddad, and R. Dana 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.
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 […]
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 prairiesSchomaker, 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 […]
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 […]
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.
