Breeding Bird Utilization Of Shelterwood-Cut Oak Stands In Buckingham County, Virginia, Kim Marie Mcdonald

Theses & Honors Papers

Breeding bird populations on three shelterwood cut oak stands in Buckingham County, Virginia were studied using Breeding Bird Census (BBC) techniques. The stands were cut partly or entirely during the year prior to the 1997 breeding season, when the BBCs were conducted. The plots were established as part of a study of oak regeneration following controlled bums in the Virginia piedmont. Canopy cover on the plots averaged 66.8% after the cuts and total basal area averaged 41915 cm2/acre. At least 23 species of birds had territories partly or entirely on at least one of the plots, and at least nine …

Establishment Of A Nighthawk Migration Monitoring Program, Jeri Paige Guilliams

Theses & Honors Papers

The Nighthawk Migration Monitoring Program was initiated in 1997 to study the Common Nighthawk, Chordeiles minor. Modeled after the Hawk Migration Association of North America's hawkwatching methodology, the program enlisted volunteers to record time of day for peak flight, time of season for peak flight, weather conditions affecting migration, and other data. Volunteers were enlisted by establishment of a web­ page and e-mail address, preparation and circulation of a brochure, and through mail.

Individual chapters of the Virginia Society of Ornithology and others expressing interest were sent a letter, brochure, a Nighthawk Count Report Form, and an instruction sheet for …

The Effect Of Wildlife Management Techniques On Grassland Birds In Central Virginia, Eric Wayne Rosenbaum

Theses & Honors Papers

The purpose of this study was to examine the effects of wildlife management techniques on grassland bird species . Grassland birds have been declining in number for the last twenty-five years (Kershner and Bollinger 1996). Their decline is attributed to overall habitat loss. This study was conducted at James River Wildlife Management Area in Nelson County, Virginia. Three grassland plots were selected to represent three different kinds of management. One plot was planted in wheat, another in corn, and one plot was burned. Birds within these plots were monitored for one year. Each plot was also subjected to a vegetational …

A Comparison Of Astm Standard E1599-94 And A Site Assessment Project Located In North Las Vegas, Kenneth Anthony Katsuda

UNLV Theses, Dissertations, Professional Papers, and Capstones

This document provides a comparison of ASTM E-1599-94 Standard for a petroleum release and the procedures performed on a site assessment project in North Las Vegas. The major elements of a site assessment are thoroughly discussed in this document. They elements consist of the Initial Site Assessment, On-Site Delineation, Off-Site Delineation, Sampling/Analysis, and Site Assessment Methodologies.

The data was obtained through extensive research, utilizing reference documents,on-site experience, and the knowledge of Keith Stewart of Stewart Environmental.

After reviewing and comparing the data of my research, the procedures applied to the North Las Vegas Site (NLVS) were quite similar to the …

The Soil Acarine Fauna Of Selected Agroecosystems Within The York Shire, Derek Juan Swarts

Theses : Honours

The practice of broadacre, dryland farming is known to affect the physico-chemical structure of the soil but our knowledge or its impact on the biological structure is rudimentary. The soil acarine (mite) communities which inhabit these soils display a variety of responses to this agricultural practice. With the increasing focus on developing ecologically sustainable agricultural techniques, an understanding of the soil acari becomes increasingly important. This study investigated the impact of two agricultural practices (designated here us Conventional and Non-Conventional) upon the abundance and diversity of the soil acari. Conventional agricultural practice involved broad scale chemical application to weeds and …

Perceptions Of Seagrass Ecosystem Health And Potential Indicators For Monitoring, Nick Wood

Theses : Honours

A range of seagrass characteristics were assessed for potential use as indicators of ecosystem health. Shoot density, shoot width, maximum shoot length, above and below ground biomass, percentage canopy cover, leaf area index, leaf extension rate, meadow productivity, epiphyte biomass, epiphyte species richness, percentage of calcium carbonate in epiphytic material and percentage of nitrogen in leaf tissue were all measured in “healthy~ and unhealthy" Posidonia augustifolia meadows in Cockburn and Warnbro Sounds, from June through to August 1998. A questionnaire was used to determine which meadows researchers and managers in the seagrass ecology field in Perth perceived to be healthy …

Carbon Sequestration Of Two Oil Mallee Species, Eucalyptus Loxophleba Subsp. Lissophloia And Eucalyptus. Kochii Subsp. Plenissima In The Semi-Arid Environment Of The Central Wheatbelt Of Western Australia, Andrew Phillip Mccarthy

Theses : Honours

The planting of "Oil malices" have a number of implications in terms of environmental management within Western Australia. Firstly, the incorporation of perennial trees on a large scale into the agricultural landscape can assist in balancing the hydrological cycle and other land degradation problems (Bird et. al. 1992; Western Australian Salinity Action Plan, 1996). Secondly, harvesting the above-ground biomass can produce an economic return because of the oil contained within the leaves. This oil has the potential to replace ozone damaging solvents (Barton and Knight, J997; Wildy, 1996). Finally, "oil mallees" have the potential to offset greenhouse gas emissions, because …

The Distribution And Long-Term Change In Banksia Ilicifolia Communities On The Gnangara Mound, Ryan Gurner

Theses : Honours

The Gnangara Mound is a large shallow groundwater aquifer which occurs in the superficial formations bounded by the Swan River, Ellenbrook, Gingin Brook, Moore River and the Indian Ocean on the northern Swan Coastal Plain. To protect terrestrial vegetation on the Gnangara Mound. groundwater levels must be maintained to allow plants access to water which is required for their survival. In areas with a shallow depth to groundwater, studies have shown that groundwater drawdown (reduction of the water table by any processes or factors) has a high potential to impact on the vegetation (Havel. 1968: Aplin. 1976: Heddle. 1980a: Dodd …

The Birds And Habitat Of Kings Park, Bradley W. Cox

Theses : Honours

Kings Park is a large urban park in the centre of Perth with extensive areas of semi-natural bushland. The park is an important refuge for birds in the metropolitan area but is losing species through habitat disturbance. Understanding the way in which birds are related to their habitat helps to understand the effect of habitat disturbance on the bird community. The aim of this project was to generate guidelines which will aid in the management and conservation of birds in the park, through an understanding of the relationship of the birds to their habitat. The avifauna and various habitat factors …
