Negative effect of purple loosestrife and reed canary grass on the diversity of wetland plant and moth communities

Creator:: Schooler, Shon
Abstract:: Invasive plants have the potential to reduce the diversity of species in plant and animal communities. I examined the negative effect of two invasive wetland plants, purple loosestrife and reed canary grass, on the species richness and diversity of plant and moth communities within 24 wetland study sites in the...

Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Exotic plant invasion from roads to stream networks in steep forested landscapes of western Oregon

Creator:: Watterson, Nicholas
Abstract:: This project explores mechanisms governing the invasion of fluvial systems by two contrasting exotic species in stream networks of steep, relatively remote forested landscapes of western Oregon. This research addresses hypotheses relating limitations of seed source locations, seed transport processes, and sink availability to the distributions of scotch broom (Cytisus...

Invasive species : what gardeners need to know

Creator:: Oregon State University. Extension Service, Emanuel, Robert, McMahan, Linda, and Jones, Joy
Abstract:: Invasive nonnative plants are a serious subject for gardeners, farmers, the general public, and land managers. Understanding invasive species and how to control them is becoming increasingly important for gardeners.

Spatial patterns of invasion by exotic plants in a forested landscape

Creator:: Parendes, Laurie Anne, 1958-
Abstract:: Few landscapes are immune to invasion by exotic plant species. The forested landscape in the western Cascade Range of Oregon appears to have some barriers to invasion, but the extensive road network provides a corridor and habitat for a suite of exotic species to enter and become established. This study...

Role of propagule pressure and priority effects on plant establishment during restoration of invaded shrub-steppe

Creator:: Schantz, Merilynn C.
Abstract:: Biological plant invasions are diminishing the ecological integrity and function of ecosystems worldwide. A primary example of this is in the Great Basin of the United States, where invasive annual grasses, like cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae L. Nevski), are dominating many sagebrush-steppe ecosystems. In these invaded...

An evaluation of the invasion potential of Kochia prostrata (forage kochia) in southwestern Idaho, USA

Creator:: Gray, Erin C.
Abstract:: Purposeful introductions of exotic species for rehabilitation efforts following wildfire are common on rangelands in the western U.S., though potential ecological impacts of introduced species in novel environments are often poorly understood. One such introduced species, Kochia prostrata (L.) Schrad (forage kochia) has been seeded on over 200,000 ha throughout...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...

Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

Creator:: Hebel, Cassie L.
Abstract:: Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...
