This project is intended to study the effectiveness of manmade vernal pools for creating habitat value, particularly within an urban setting. Natural vernal pool habitats are under threat across the United States as filling and development activities have led to permanent loss of habitat. Mitigation requirements or other restoration/creation activities...
This thesis explored the distributions and life histories of dragonflies and damselflies (Insecta: Odonata) of the riverine wetlands of the Willamette Valley in western Oregon, USA. Odonate species distributions were characterized over two seasons in the autumn of 2000 and the spring of 2001-at twenty-seven wetlands located throughout the valley....
Great Salt Lake (GSL), Utah, is surrounded by 191,884 hectares of wetlands. These wetlands provide critical habitat for hundreds of thousands of breeding, migrating and wintering waterfowl each year. As the human population around GSL increases, government officials have proposed to divert more water from the Jordan, Ogden, and Bear...
An estimated 99% of native wet prairie has been lost in the Willamette Valley, Oregon, but a large number of seasonal wetlands remain on private lands dedicated to grass seed production within the historical wet prairie landscape. Because agriculture is known to alter physical and chemical wetland conditions, I investigated...
The internship I performed was with Rural Community Development Program (RCDP), a domestic non-governmental organization in the country of Nepal. This organization focuses on community development goals in rural communities, utilizing the efforts of volunteers within the context of environmental conservation ideals. I primarily worked with the associated community plant...
Great Lakes coastal wetland communities are threatened by the impacts of invasive plants on ecosystem function and biodiversity. What allows invasive plants to become dominant in invaded communities can be hard to define and context-dependent. Traits associated with invasion success in wetland systems – rapid vegetative growth, competitive superiority in...
Reducing the cover of non-native species is one of the challenges of ecosystem restoration. The goal of this study is to identify native species traits that will increase native species cover and reduce non-native species cover in the first growing season at upland and wetland prairie restoration sites. Native and...
The West Eugene Wetlands, Eugene, Oregon, which provide habitat for number of endemic and endangered plant species, are currently threatened by a Reed canarygrass (Phalaris arundinacea L.) invasion. This study addresses the hypothesis that Phalaris spread can be explained in part by using watershed-scale landuse patterns as surrogates of the...
