Wetland Mitigation Banking As A Tool For Conservation, Reid Beauregard Sisson
Wetland Mitigation Banking As A Tool For Conservation, Reid Beauregard Sisson
Masters Theses and Doctoral Dissertations
This comment proposes that wetland mitigation banking under Section 404 of the Clean Water Act be employed by land trusts and conservation groups to generate revenue for funding land acquisitions and on-going stewardship for both wetland and wetland-related upland habitats threatened or impacted by development. Conservation groups and land trusts can use mitigation banking to generate revenue to fund their conservation goals. General background on the Clean Water Act - Section 404 and regulations affecting wetlands, compensatory mitigation and mitigation banking is provided. Included are general problems with monitoring and enforcement of mitigation, pros and cons of preservation as compensatory …
Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang
Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang
UNLV Theses, Dissertations, Professional Papers, and Capstones
Sea turtles appeared more than 200 million years ago in the late Triassic period. They grow very slowly, taking an average of 25 years to reach sexual maturity, with a life span averaging 40-50 years. From May to October green sea turtles (Chelonia mydas) emerge during the night and follow light cues toward the sea. Recently, beachfront development has increased hatchling mortality rate. When hatchlings emerge from nest, high densities of artificial lights lead them toward the land where they either desiccate and die, or are preyed upon. Short-wavelength high intensity light and the distance of artificial light are the …
Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc
Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc
UNLV Theses, Dissertations, Professional Papers, and Capstones
During the summer of 1999, soil samples were taken from the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Although lead shot has been banned for the hunting of waterfowl since 1986, it is still legal for upland game hunting. The field sampled serves primarily as a dove hunting area and is cultivated. A large sample size was taken to indicate the short-term effects of the deposition of lead shot in the area and a small sample size, the long-term. Lead shot was recovered from 64% of the small samples and the estimated concentration …
Special Event Recycling: The Future Of Unlv's Recycling Program, Katherine A. Baker
Special Event Recycling: The Future Of Unlv's Recycling Program, Katherine A. Baker
UNLV Theses, Dissertations, Professional Papers, and Capstones
The current recycling program on the University of Nevada Las Vegas (UNLV) campus does not have a special event recycling aspect. The purpose of this study was to develop a special event recycling program and make recommendations of how to effectively implement it on the UNLV campus. In order to develop this special event recycling program data was collected through surveys and a pilot study. The data collected was then used to formulate recommendations. Recycling two different kinds of events, a walk and a concert tested those recommendations. Waste stream analyses were done on each event. The waste stream diversion …
The Growth And Distribution Of The Green Alga Cladophora At Presqu'ile Provincial Park: Implications For Management (Ontario), Dolf Craig Dejong
The Growth And Distribution Of The Green Alga Cladophora At Presqu'ile Provincial Park: Implications For Management (Ontario), Dolf Craig Dejong
Theses and Dissertations (Comprehensive)
The Green alga genus Caldophora is one of the most abundant kinds of algae worldwide, found in both freshwater and marine environments. It prefers nutrient-rich waters and requires a rocky substrate and water movement for growth. When water temperatures reach 22 to 26 C, the alga dies and washes into shore in large mats. Dead Cladophora produces a terrible odour, reduces property values and can alter the taste of drinking water. At Presqu’ile Provincial Park, maximum Cladophora sloughing occurred July 22 1999, the same time as peak summer park visitation begins. This results in the fouling of the Park’s beaches …

The Management Of Complex Sociobiophysical Systems: Ecosystem-Based Management And The Chesapeake Bay Program, Daniel Dennis Mccarthy
The Management Of Complex Sociobiophysical Systems: Ecosystem-Based Management And The Chesapeake Bay Program, Daniel Dennis Mccarthy
Theses and Dissertations (Comprehensive)
There are an entire class of entities for which conventional scientific understanding is necessary but not sufficient to comprehend. These entities are too complex for analysis and yet too organized for statistics. They exist in a dynamic balance between the ordered and the disordered. They are ecosystems and human institutions. They are complex systems. There is an emerging body of theory that is providing insight into the structures and dynamics that underlie such entities. Under the rubric of complex systems theory, catastrophe theory, chaos theory, hierarchy theory and the interrelated theories of self-organization have profound implications for the way understand …
Killbear Provincial Park: The Beach And Dunes, Their Use And The Implications For Management (Ontario), Kathryn Ann Parlee
Killbear Provincial Park: The Beach And Dunes, Their Use And The Implications For Management (Ontario), Kathryn Ann Parlee
Theses and Dissertations (Comprehensive)
Beaches, and in particular sand dunes, are extremely fragile environments, easily altered by human activities. Intensive use of the beach/dune complex at Killbear Provincial Park near Parry Sound, Ontario may have led to the severe degradation of its dune system within Kilcoursie Bay. At present the dunes have been degraded back to an embryonic state, and as a result it is necessary to consider the development of management strategies before the system is completely destroyed. In order to develop effective management strategies however, it is necessary to understand how the natural process of the system work and the specific effects …
Identifying Areas Of Concern For Regional Cumulative Effects Assessments In And Around Northern National Parks In Canada (Yukon), Jennifer L. Lenton
Identifying Areas Of Concern For Regional Cumulative Effects Assessments In And Around Northern National Parks In Canada (Yukon), Jennifer L. Lenton
Theses and Dissertations (Comprehensive)
This thesis uses a literature review of protected areas selection, park management, comprehensive regional land use planning, and cumulative environmental effects and assessment to develop a methodology that identifies areas with concentrations of social and/or ecological values in and around northern national parks. The proposed methodology involves two stages. First, a database of values is developed by taking an inventory of social and ecological values through exxtensive literature reviews, interviews, and consultation with the public. This database is then used in the second step to determine areas with concentrations of social and/or ecological values, or “value hotspots”, using a series …
