Conservation of Rorippa columbiae : an evaluation of reintroduction potential through the study of germination ecology, propagation methods, and habitat requirements

Creator:: Kentnesse, Laura E.
Abstract:: Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...

An experimental reintroduction of Pleuropogon oregonus, a rare wetland grass native to Oregon

Creator:: Groberg, Matthew G.
Abstract:: Pleuropogon oregonus Chase is a rare wetland grass endemic to eastern Oregon. The species is composed of two widely separated populations, one in Lake County and one in Union County. In order to reduce the risk of extinction, the Oregon Department of Agriculture Native Plant Conservation Program initiated several reintroduction...

Experimental reintroduction of northern wormwood (Artemisia campestris var. wormskioldii), a rare species of dynamic cobble bar environments on the Columbia River

Creator:: Brickner, Alexis H.
Abstract:: Rare plant reintroductions that result in additional or more viable wild populations are important conservation tools for maintaining biodiverse ecosystems. Ideally, such projects are best designed as experiments, to improve biological and ecological knowledge of the selected species and monitoring long-term results. Northern wormwood (Artemisia campestris var. wormskioldii: Asteraceae), a...

Conservation biology of Plagiobothrys hirtus (Boraginaceae) : evaluation of life history and population enhancement

Creator:: Amsberry, Kelly
Abstract:: Plagiobothrys hirtus (Boraginaceae) is a state and federally listed endangered plant found only in Douglas County, Oregon. This vernal pool endemic has historically been threatened by agricultural conversion of seasonal wetlands in the Sutherlin area, and is currently being eradicated as habitat is lost due to the rapid urban development...

The influence of prescribed fire on the rare endemic plant Delphinium pavonaceum (Peacock larkspur)

Creator:: McKernan, Brie-Anne
Abstract:: In the wetland prairie of William L. Finley National Wildlife Refuge (FNWR) in western Oregon, we investigated the response of Delphinium pavonaceum Ewan (peacock larkspur, Ranunculaceae), an endangered perennial forb, to four unreplicated dormant season fire regimes of 0, 2, 4, or 10 fires that were applied over a 12-year...

Conservation biology of Perideridia erythrorhiza (Apiaceae) : experimental reintroduction and life history

Creator:: Roberts, Kimberly A.
Abstract:: An experimental reintroduction was performed to determine the best method to create new populations of the tuberous species Perideridia erythrorhiza, a rare vascular plant endemic to southern Oregon. Only a handful of sites are currently present, and many of these are subject to other land uses such as urban development...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Reproduction, demography, and habitat characterization of Astragalus peckii (Fabaceae), a rare central Oregon endemic

Creator:: Martin, Elizabeth F.
Abstract:: With little previous research on Astragalus peckii (Fabaceae), a state-listed Threatened species in Oregon, I investigated three facets of its biology which are integral to the conservation and management of the species. First, a four-year demographic study of two large populations revealed increasing population growth at one site (Chiloquin) and...

Reproductive isolation and interspecific hybridization in the threatened species, Sidalcea nelsoniana

Creator:: Gisler, Steven D.
Abstract:: In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
