Abronia umbellata var. breviflora on the Oregon coast: Reintroduction and population monitoring

Denise E.L. Giles-Johnson and Thomas N. Kaye   2014

Pink sand-verbena (Abronia umbellata var. breviflora) is listed by the Oregon Department of Agriculture as endangered, 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 dwindled from around ten down to about five. The primary threats to the species include […]

Development of propagation protocols for Bartonberry (Rubus bartonianus)

Bahm, Matt A. and Erin C. Gray   2014

This report discusses our first year’s findings on the propagation requirements of Bartonberry (Rubus bartonianus), a federal species of concern,endemic to Hells Canyon along the Snake River and its tributaries within Oregon and Idaho. Preliminary results from this study indicate that Bartonberry can be propagated from both seed and cuttings, under a variety of treatments. High […]

Clear Creek Canyon Natural Area Upper Bench Restoration Plan

Axt, Ben   2014

This restoration plan outlines restoration activities to occur at Metro’s Clear Creek Canyon Natural Area. The plan develops the next stage of planning for restoration of the 133 acre Upper Bench Savanna area, which  will be comprised of a mosaic of habitat types, including savanna, Oregon white oak (Quercus garryana) woodland, wet prairie, shrub, and […]

Habitat and population monitoring for Chloropyron maritimum ssp. palustre and Limonium californicum on the Coos Bay North Spit

Giles, D.E.L., E.C. Gray, and T.N. Kaye   2014

EXECUTIVE SUMMARY In 2014 the estimated number of Chloropyron maritimum ssp. palustre plants on the Coos Bay North Spit land managed by the Coos Bay District of the Bureau of Land Management is ~1,511,000 (508,000 in the protected area and 1,003,000 in the unprotected area). This is the highest estimated population in the unprotected area, […]

Factors Influencing Germination of a Functionally Important Grassland Plant, Iris tenax

Jones, Katherine and Thomas Kaye   2013

Grassland prairies of western Oregon and Washington are among the most endangered ecosystems in the United States. Active management and restoration are needed to promote biodiversity in the region. To support plant production for use in habitat restoration, we developed germination protocols for greenhouse propagation of Iris tenax (Oregon iris). Dormancy was most effectively overcome […]

Effects of climate change on Kincaid’s lupine

Erin C. Gray, Sarah T. Bois, and Thomas N. Kaye   2013

Kincaid’s lupine (Lupinus oreganus), a rare legume found in prairies and oak savannas, is listed as threatened by the US Fish and Wildlife Service and the Oregon Department of Agriculture, and endangered by the Washington Department of Natural Resources. Extensive land development and alteration in the prairies of western Oregon and southwestern Washington have relegated remaining populations to small, […]

Climate change vulnerability assessment for West Eugene Wetland species

Thomas N. Kaye, Ian Pfingsten, Trevor Taylor and Emily Steel   2013

Local climate is one important factor that controls species distributions,range, phenology, and ability to compete with non-native species, among many effects. To preserve rare grassland species, manage and restore grassland habitat, and maintain communities that are resilient to climate change in the Pacific Northwest (PNW), land managers and restoration practitioners in the Willamette Valley (WV) need […]

Habitat monitoring and improvement for Cordylanthus maritimus ssp. palustris

Giles-Johnson, Denise, Erin C. Gray and Thomas N. Kaye   2013

This project aims to monitor C. maritimus ssp. palustris populations within the North Spit of Coos Bay, Oregon. Through a combination of annual mapping and monitoring, we will track changes in population size and location through time. We will also test the effect interspecific competition on recruitment by experimentally removing neighboring species in a subset of the […]

Lomatium cookii population monitoring in the Illinois Valley, Josephine County, Oregon

Ian A. Pfingsten, et al.   2013

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 since 1994 […]

Developing reintroduction techniques for Lomatium cookii

Thomas N. Kaye, et al.   2013

The goal of this project was to develop reintroduction techniques for Lomatium cookii to support recovery of the species. The specific objectives of this study included: determining survival and growth of new individuals propagated from both seeds and root plugs, observing the effects of litter removal on  L. cookii transplant survival, testing for local adaptation of seeds sources, […]
