Interests And Priorities In Sockeye Salmon Management: How Are Policies Enacted And Interpreted On Three Alaskan Rivers?, Jake P. Palazzi Oct 2020

Interests And Priorities In Sockeye Salmon Management: How Are Policies Enacted And Interpreted On Three Alaskan Rivers?, Jake P. Palazzi

University Honors Theses

The large export abundance of Alaskan salmon is well documented, and many studies have been performed to assess the economic and environmental viability of the industry and its management. Less research has been done to characterize how state intentions regarding fisheries allocation are conceived of by management or perceived by vulnerable groups in the user pool. This study seeks to qualitatively characterize the disconnect between state and Native Alaskan perceptions of management effectiveness, public interest, and Native Alaskan involvement using interviews. Results showed that Native Alaskan and state manager respondents had very different perceptions of management effectiveness and equity. When …


Social-Ecological Dynamics Of Coral Reef Resource Use And Management, Sarah J. Freed Jul 2013

Social-Ecological Dynamics Of Coral Reef Resource Use And Management, Sarah J. Freed

Dissertations and Theses

This dissertation investigates social and ecological factors that facilitate effective management of coral reefs as social-ecological systems. Meta-analytical and field-based methods were employed to examine current management challenges and identify strategies that improve management effectiveness and coral reef health. A meta-analysis was used to evaluate biological indicators of reef health in relation to the types of fishing regulations in place (no-take areas, gear restriction areas, and periodic closures) and the actor groups (community-based, co-management, state, private) involved in management efforts for coral reef fisheries throughout the world. Other than enhancement of fish biomass within no-take areas that was significantly greater …


Spatial And Temporal Patterns Of Amphibian Chytrid Fungus Batrachochytrium Dendrobatidis Occupancy In Amphibian Habitats, Tara Chestnut Jan 2013

Spatial And Temporal Patterns Of Amphibian Chytrid Fungus Batrachochytrium Dendrobatidis Occupancy In Amphibian Habitats, Tara Chestnut

Environmental Science and Management Professional Master's Project Reports

Chytrid fungi are the most ancestral of the fungi and are global in distribution. There are over 1200 species of Chytridiomycota described from freshwater, marine and terrestrial systems in temperate, tropical and tundra environments. Chytridiales are characterized by a range of morphologies and share the flask- or pot-like shape of the zoosporangia, within which motile zoospores develop. Chytrids function primarily as plant saprobes and parasites, but some also parasitize animals. Chytrids are observed in conjunction with the decline of freshwater and marine algal blooms, they decompose excess pollen, and comprise the fungal flora in gut of herbivores. Some chytrids also …


Integrating Ecosystem Services, River Restoration And Community: A Case Study At Fisher's Bend, Michael Carlson Oct 2011

Integrating Ecosystem Services, River Restoration And Community: A Case Study At Fisher's Bend, Michael Carlson

Environmental Science and Management Professional Master's Project Reports

Natural areas and ecosystem services at the edge of urban areas are threatened by increasing development. This paper examines how community based restoration partnerships can work to identify, protect and restore ecosystem services provided by salmon and our local rivers. Floodplains provide a wide range of ecosystem services to urban and rural communities and we should work collaboratively to protect and restore them. Floodplains are especially valuable and important for salmon recovery. By using a case study, we explore the process and feasibility of restoring off-channel salmon habitat at Fisher's Bend in the lower Clackamas river. A feasibility study was …


Vegetation, Environmental Characteristics, And Their Relationships: Variation Within The Annually Flooded Riparian Zones Of The John Day River Basin, Oregon, Samuel J. Hartsfield Feb 2009

Vegetation, Environmental Characteristics, And Their Relationships: Variation Within The Annually Flooded Riparian Zones Of The John Day River Basin, Oregon, Samuel J. Hartsfield

Dissertations and Theses

I hypothesized that vegetation and physical environmental characteristics would differ between the upper and lower extents of the annually flooded riparian zone on the John Day River, and that relationships between species and environmental variables would display differences between these two zones. Vegetation, environmental variables, and relationships between them were assessed for the entire annually flooded riparian zone, and for the proposed upper and lower zones. Data were collected from 60 one-square-meter quadrats: 30 in each the upper and lower zones. Sites were randomly selected and located so that flood duration was roughly equal at all sites within each zone. …


Koll Center Wetlands Natural Resources Maintenance Management Plan, Meredith Clayton Oct 2006

Koll Center Wetlands Natural Resources Maintenance Management Plan, Meredith Clayton

Environmental Science and Management Professional Master's Project Reports

The intention of this plan is to provide a vision and guidelines for maintaining and improving the ecological health of Koll Center Wetlands in the short and long term. Although the plan will change over time, the goal is to quantify natural resource needs spatially, temporally, and economically.

Koll Center Wetlands is part of the Greenway/Fanno Creek/Koll Center Wetlands Park complex. The nearly 13 acre park is dominated by aquatic habitats that attract a wide variety of wildlife, particularly birds. The park grounds are not easily traversed and experience limited human use, but there are many viewpoints from which the …
