Recruitment predictors of an endangered prairie species : a case study of Erigeron decumbens

Creator:: Gallagher, Katie J.
Abstract:: Preservation of rare plant species often requires establishment of new populations. Survivorship surveys are the most common method of post-introduction monitoring. However, they provide an incomplete picture of establishment success. This study is an attempt to develop a model for determining establishment success by determining the factors affecting recruitment in...

The effects of site preparation on native forb establishment in a wet prairie, Willamette Valley, Oregon

Creator:: Norman, Katherine N.
Abstract:: Wetlands and wet prairies are economically and environmentally valuable ecosystems, but many have been degraded or converted to other uses. As human understanding of wetlands' value has increased, restoration efforts have grown correspondingly. Restoration attempts use a diversity of methods, which often include seeding with native plant species. This thesis...

West Eugene Native Wetland Restoration Research Project: Seed Dormancy, Germination, and Establishment

Creator:: Wilson, Mark V., Ingersoll, Cheryl A., and Clark, Deborah Louise, 1950-
Abstract:: Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...

The effects of two fuel reduction treatments on chaparral communities in southwest Oregon

Creator:: Sikes, Kendra G.
Abstract:: Fuel reduction treatments are being applied to public lands, affecting significant acreage at considerable expense. This study compares the short term effects on a chaparral plant community of two different fuel reduction methods, brush mastication and "hand piling and burning" (HPB). Ceanothus cuneatus dominated the southwestern Oregon study sites where...

Salt marsh reestablishment following dike breaching in the Salmon River estuary, Oregon

Creator:: Mitchell, Diane Lynne
Abstract:: A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...

Final report 1994-1996 : Effects of fire and fire fighting techniques on Fender's blue butterfly and Kincaid's lupine

Creator:: Clark, Deborah Louise, 1950- and Wilson, Mark V.
Abstract:: We report results from a field experiment evaluating the effectiveness of mowing, mowing and herbicides, and burning on woody plants, key native and non-native grasses and forbs, and the Fender's blue butterfly. The goal was to find a technique that controlled woody pest plants without harming native species or promoting...

Recommendations for Control of Tall Oatgrass, Poison Oak, and Rose in Willamette Valley Upland Prairies

Creator:: Wilson, Mark V. and Clark, Deborah Louise, 1950-
Abstract:: Native upland prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon's ecosystems. Even though only remnants remain today, they harbor many rare and endangered species such as the Fender's blue butterfly and its host plant, Kincaid’s lupine. Invasion of remnant prairies by...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...

Factors limiting the distribution of the sensitive lichen Usnea longissima in the Oregon Coast Range : habitat or dispersal?

Creator:: Keon, Dylan B.
Abstract:: The sensitive lichen Usnea longissima Ach., formerly a fairly common circumboreal species, has been extirpated from much of its range (e.g., Eastern Europe). Although the U.S. Pacific Northwest (PNW) remains a relative stronghold for the species, U longissima faces increasing pressure in the region from habitat loss, air pollution, and...
