Evaluation Of Best Management Practices To Reduce Nutrients Runoff In Watersheds In Arkansas, Hector German Rodriguez Diaz
Evaluation Of Best Management Practices To Reduce Nutrients Runoff In Watersheds In Arkansas, Hector German Rodriguez Diaz
Graduate Theses and Dissertations
There are many non point sources (NPS) of pollution issues across the state of Arkansas. Each region of the state has different concerns. Many watersheds have been included in the Arkansas's 2008 303(d) list for NPS impairments with sediment and nutrients being the primary causes of concern. This research hypothesized that there are no cost or net returns risks when adopting best management practices (BMPs) to control nutrients runoff and that selection, timing, placement and cost have no impact on the implementation of BMPs. Using two priority watersheds, the L'Anguille River and the Lincoln Lake, as examples, the environmental benefits …
Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Effects Of Tide Gate Replacement On Water Temperature In A Freshwater Slough In The Columbia River Estuary, Sara Ennis
Environmental Science and Management Professional Master's Project Reports
Dramatic declines in salmon populations in the Pacific Northwest have brought new attention to the importance of estuarine rearing habitats. Levees and tide gates used to convert estuarine wetlands into farmland have reduced available habitat by more than half of historical levels. Recent efforts to restore estuarine habitats include tide gate replacement, though this method has been poorly studied. As a key indicator of salmon habitat suitability, temperature was used to evaluate the effects of tide gate replacement in a tidally influenced freshwater slough in the Lower Columbia River estuary. Three tide gates in the largest slough on Tenasillahe Island …
Vegetation, Environmental Characteristics, And Their Relationships: Variation Within The Annually Flooded Riparian Zones Of The John Day River Basin, Oregon, Samuel J. Hartsfield
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. …
Learning The Lay Of Their Land: Data Recording By Maine Land Trusts, Patrick John Roche
Learning The Lay Of Their Land: Data Recording By Maine Land Trusts, Patrick John Roche
Honors Theses
Land trusts have led the recent, rapid expansion in private land conservation in the US. As they have grown, many questions have emerged as to the value of their conservation efforts, especially in the long-term. To address this data gap, studies have evaluated easement restrictions and the characteristics of land trust protected property. I take a novel approach by investigating the data that land trusts record about their protected properties and its impact on their capacity to protect conservation values. I surveyed 55 land trusts operating in Maine about data they record in baseline documentation reports. A majority (82%) had …
The Mckee Preserve Management Options At Bandon Dunes Golf Resort, Ashley Marie Edwards
The Mckee Preserve Management Options At Bandon Dunes Golf Resort, Ashley Marie Edwards
Environmental Science and Management Professional Master's Project Reports
The McKee Preserve is a new conservation area at Bandon Dunes Golf Resort, located on the southern Oregon coast. The Preserve is 250 acres in size and is made up of 13 different natural resource communities. One important resource is silvery phacelia (Phacelia argentea), which is a state threatened plant species and is a species of concern federally. The goal of this project was to perform plant inventories for silvery phacelia and kinnikinnick that will be used to establish a functional management plan for the Preserve. Other resources of interest to the Preserve have been included in the …
Downspout Disconnection Suitability And Incentives Analysis For The City Of Gresham, Oregon, Brian C. Fletcher
Downspout Disconnection Suitability And Incentives Analysis For The City Of Gresham, Oregon, Brian C. Fletcher
Environmental Science and Management Professional Master's Project Reports
The City of Gresham is developing a Downspout Disconnection Program, which encourages homeowners to disconnect their roof downspouts from the storm sewer system and divert the stormwater onto their lawn or rain garden. Downspout disconnection is being evaluated for its effectiveness to help the city meet stormwater discharge requirements in their NPDES-MS4 permit from Oregon DEQ. This study reviewed current Natural Resources Conservation Service (NRCS) soil data and developed a suitability map showing High, Medium and Low suitability zones for on-site stormwater management. To validate the map, 55 soil textural classes and 11 infiltration rates were determined at residences throughout …
Toward A More Holistic Approach To The Conservation Management Of Southern Ontario’S Small Protected Areas, Wilfred Gregory Tschirhart
Toward A More Holistic Approach To The Conservation Management Of Southern Ontario’S Small Protected Areas, Wilfred Gregory Tschirhart
Theses and Dissertations (Comprehensive)
Within Southern Ontario’s highly fragmented greater natural ecosystem, there remain numerous relatively small scattered areas which bear at least some resemblance to their former pre-European/Canadian settlement natural ecosystem. In their present state they serve as reservoirs of their particular ecoregion’s indigenous plant and animal species. In proportion to their limited spatial areas, degree of isolation, existing ecological integrity, and long-term ecological carrying capacity they are stores of natural capital, which is beneficial to both nature and society. They co-exist with Southern Ontario’s well developed socioeconomic/cultural system, on whose stewardship their long-term integrity is becoming increasingly dependent, which creates increased environmental …
Inuit Qaujimajatuqangit And Adaptive Co-Management: A Case Study Of Narwhal Co-Management In Arctic Bay, Nunavut, Aaron T. Dale
Inuit Qaujimajatuqangit And Adaptive Co-Management: A Case Study Of Narwhal Co-Management In Arctic Bay, Nunavut, Aaron T. Dale
Theses and Dissertations (Comprehensive)
Since 2001 the community of Arctic Bay, located on north-western Baffin Island, in Nunavut, Canada, has been experimenting with a new approach to narwhal management—‘community-based’ narwhal managemet. The new management system has developed some decision-making powers to the local Hunters’ and Trappers’ Organization, who are empowered/required to draft by-laws to govern the hunt. Community-based narwhal management links local, regional, territorial, and national actors and agencies in a co-management arrangement that draws its powers from, and is steered by, the Nunavut Final Agreement (1993), the comprehensive land claims agreement between the Inuit of Nunavut and Her Majesty the Queen in Right …
