An evaluation of the potential for hybridization between Castilleja levisecta and C. hispida

Kay, Thomas N. and Matt Blakeley-Smith   2008

Catilleja levisecta (Golden paintbrush) is listed as Endangered Species by the US Fish and Wildlife Department. The Recovery Plan for C. levisecta identifies population reintroduction, development of propagation methods, and studies of the pollination biology of the species as high priority actions to meet recovery objectives. A second paintbrush species, C. hispida (harsh paintbrush), also occurs in prairies along […]

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

Denise Giles-Johnson, Erin C. Gray, and Tara Callaway   2014

This report documents research conducted on population dynamics and habitat for of Kincaid’s lupine (Lupinus oreganus), a threatened species in the legume family, 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). […]

Lupinus sulphureus spp. kincaidii (Kincaid’s lupine) and Icaricia icarioides fenderi (Fender’s blue butterfly) in the West Eugene Wetlands: Population monitoring, reintroduction success, and an evaluation of experimental treatments

Denise E. L. Giles-Johnson, et al.   2010

This report documents research conducted on Kincaid’s lupine (Lupinus sulphureus ssp. kincaidii), a threatened species in the legume family. Kincaid’s lupine serves as an obligate larval host plant for the endangered Fender’s blue butterfly (Icaricia icarioides fenderi). Both species are endemic to western prairies. The specific objectives of this project are to 1) describe trends […]

Abating climate change impacts on Kincaid’s lupine

Erin C. Gray and Matt A. Bahm   2016

This document summarizes monitoring of reintroductions of Kincaid’s lupine in multiple microclimates at three sites in the Willamette Valley, Oregon.  Over the years of this study, we have found that seed source and microclimate both affect emergence, survival, and growth (height and number of leaves).  Results will inform future management considerations regarding seed transfer zones […]

Lupinus sulphureus ssp. kincaidii (Kincaid’s lupine) and Icaricia icarioides fenderi (Fender’s blue butterfly) in the West Eugene Wetlands: Population Monitoring, Reintroduction Success, and an Evaluation of Experimental Treatments

Denise E.L. Giles-Johnson, et al.   2010

This report documents research conducted on Kincaid’s lupine (Lupinus sulphureus ssp. kincaidii), a threatened species in the legume family. Kincaid’s lupine serves as an obligate larval host plant for the endangered Fender’s blue butterfly (Icaricia icarioides fenderi). Both species are endemic to western prairies.

Reintroduction of Lupinus sulphureus ssp. kincaidii (Kincaid’s lupine) to Dragonfly Bend in the West Eugene Wetlands

Andrea S. Thorpe, et al.   2009

In the Willamette Valley, Kincaid’s lupine serves as the primary larval host plant for the endangered Fender’s blue butterfly, making conservation of the lupine a common strategy for the success of both species. The objective of this project was to introduce Kincaid’s lupine to Dragonfly Bend, a wetland mitigation site located in the West Eugene […]

Effects of grazing and climate on Greene’s mariposa lily in the Cascade-Siskiyou National Monument

Carolyn Menke, et al.   2012

Calochortus greenei S. Wats., Greene’s mariposa lily, is listed by the United States Fish and Wildlife Service (USFWS) as a federal species of concern, and is proposed for listing as a threatened species in Oregon. It is also a Bureau of Land Management (BLM) special status species. This project aims to monitor  C. greenei populations […]

Reintroduction of golden paintbrush to Oregon: 2012 annual report

Thomas N. Kaye, et al.   2012

This project supports the recovery of C. levisecta through full-scale reintroduction to prairie sites in Oregon’s Willamette Valley. This is a three-year project that begins with trial plantings at several locations to identify suitable locations for the species’ growth, followed by monitoring and additional plantings. This interim report summarizes information from the first full year […]

Studies to facilitate reintroduction of Golden paintbrush (Castilleja levisecta) to the Willamette Valley, Oregon. Chapter five: Growing Castilleja for restoration and the garden

Beth A. Lawrence   2005

Hemiparasitic Castilleja have been described as “nearly impossible to cultivate in a garden” (Art 1990), with “many problems associated with growing them from seed” (Borland 1994). Nevertheless, through may trials and experimentation we have successfully grown more than 3000 individuals of golden paintbrush (Castilleja levisecta), an endangered perennial endemic to the Pacific Northwest, for restoration […]

Habitat variation throughout the historic range of golden paintbrush, a Pacific Northwest prairie endemic: Implications for reintroduction

Beth A. Lawrence, Thomas N. Kaye   2006

Although golden paintbrush historically inhabited the prairies of the Willamette Valley, Oregon, this Pacific Northwest prairie endemic is currently restricted to eleven sites in the Puget Trough of Washington and British Columbia. Recovery criteria call for the establishment of new populations throughout the species’ historic range, including the Willamette Valley. We described vegetation and soil […]
