The Plants for People project integrated native plant production, culturally important plant species, and traditional ecological knowledge into restoration at two Willamette Valley sites in 2014-16. Seeds of coast tarweed, cow parsnip and barestem biscuitroot were collected and put into production, with 10 pounds of tarweed seed harvested in 2016. Large camas, Gairdner’s yampah and […]
This report summarizes vegetation monitoring conducted at Herbert Farm and Natural Area, Corvallis, Oregon, during 2016.
Controlling exotic grasses while maintaining native plant communities in fire-maintained wet prairiesBahm, Matt A., Andrew T. Esterson, and Erin C. Gray 2016
EXECUTIVE SUMMARY Overall, several treatment(s) show promise for individual aspects that we were considering (Anthoxanthum odoratum cover, native species cover, and exotic species cover). Currently, no individual treatment tested provides desired levels of all of the measured variables. Future monitoring is necessary to continue to refine the management techniques and provide the most accurate recommendations. […]
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 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, and 2) the effects of prescribed fire on L. cookii and the surrounding plant community at French Flat Middle […]
This report documents research 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 endemic to […]
The Institute for Applied Ecology monitored populations of Pyrrocoma radiata (Snake River goldenweed) on land managed by the BLM Vale District in 2015 and 2016. • We monitored 26 sites occurring on Vale BLM lands in 2015, including 1 previously undocumented site. o Identified 1 previously undocumented population. o Counted/estimated 16,368 plants, with sites ranging […]
