An Evaluation Of The Productivity Of Two Oil Mallee Species In A Revegetation Trial In The Central Wheatbelt Of Western Australia, Beatrice Lucie Hedwig Franke Jan 1997

An Evaluation Of The Productivity Of Two Oil Mallee Species In A Revegetation Trial In The Central Wheatbelt Of Western Australia, Beatrice Lucie Hedwig Franke

Theses : Honours

Two of Western Australia's most pressing land degradation problems are waterlogging and increasing soil salinity. Extensive clearing of the native. deep-rooted vegetation and its replacement with shallow-rooted crop and pasture plants has resulted in increased recharge of groundwater tables. causing them to rise. Salts stored in the soil are being brought to the soil surface with the rising watertables. Revegetation with deep-rooted native plants has been identified as the most likely strategy to achieve increased groundwater usage and a lowering of watertables. One area seriously affected by waterlogging and increasing salinity is the Western Australian central wheatbelt region. The Department …


Small Mammals Of Point Pelee National Park: Protecting Biodiversity In Small Reserves (Ontario), Julie Ann Spicer Jan 1997

Small Mammals Of Point Pelee National Park: Protecting Biodiversity In Small Reserves (Ontario), Julie Ann Spicer

Theses and Dissertations (Comprehensive)

Habitat destruction, fragmentation and degradation have been widespread throughout southern Ontario with devastating effects on wetlands. Small reserves are all that in this highly agricultural/urban landscape to protect the biodiversity of Great Lakes Marsh and Carolinian Forest ecosystems. Small reserves are vulnerable to species loss through a host of problems related to size and as a result, the value of small reserves to conservation strategies has often been questioned. Indicator species can be used as a means of studying the conditions of complex ecosystems. In this research, small mammals were sampled in the wetlands of Point Pelee National Park as …


Sagebrush (Artemisia Tridentata) Restoration In Altered Sage Grouse (Centrocercus Urophasianus) Habitat Of The Yakima Training Center In Central Washington, Margaret Ann Pounds Jan 1997

Sagebrush (Artemisia Tridentata) Restoration In Altered Sage Grouse (Centrocercus Urophasianus) Habitat Of The Yakima Training Center In Central Washington, Margaret Ann Pounds

All Master's Theses

The restoration of sagebrush at the Yakima Training Center was studied because it was determined that military training was altering the condition of sage grouse habitat, potentially having a negative impact on the sage grouse population of the installation. The management of sage grouse and its habitat on YTC are a priority for the U.S. Army. The objectives of this study were to identify the issues relevant to sage grouse and the restoration of its habitat on the training facility, to investigate sagebrush restoration techniques, and to make management recommendations based upon this study. Results of this study indicate that …

Response Surface Methodology: An Analytical Method For Locating Migrated Contaminant Sources, Orlando J. Dona Jr. Jan 1997

Response Surface Methodology: An Analytical Method For Locating Migrated Contaminant Sources, Orlando J. Dona Jr.

Theses and Dissertations

The use and storage of hazardous chemicals at U.S. military facilities often adversely affect the groundwater when contaminants infiltrate the subsurface as a result of leaks and accidental spills. These contaminants, if not located and remediated in a relatively short time, may move and settle unpredictably, essentially creating a source some distance from the original leak or spill. An example of this phenomenon is found with migrating dense nonaqueous phase liquid (DNAPL) contaminants. Although various methods for estimating the present day locations of these migrated contaminants are in use, accurately pinpointing the source of contaminants remains a difficult problem in …
