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 […]

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 […]

Reintroduction of Castilleja levisecta: Effects of ecological similarity, source population genetics, and habitat quality

Beth A. Lawrence and Thomas N. Kaye   2009

A suite of ecological and genetic factors are likely to contribute to reintroduction performance. Potential factors include the ecological similarity between seed source and introduction site, population size and genetic diversity of seed sources, and the habitat quality of the introduction site. We conducted common garden experiments with golden paintbrush (Castilleja levisecta), an endangered species […]

Direct and indirect effects of host plants: Implications for reintroduction of an endangered hemiparasitic plant (Castilleja levisecta)

Beth A. Lawrence and Thomas N. Kaye   2008

Rare, parasitic plants pose an interesting challenge to restoration practitioners. In addition to the problems associated with small population size, rare parasites may also be limited by their host requirements. We examined how the performance of a rare Pacific Northwest hemiparasite, Castilleja levisecta, was affected by the availability of different host combinations in the greenhouse […]
