Disturbed Areas: Literature and Emergency Law in Kashmir and Northern Ireland
This thesis is a study of the literature of ‘disturbed areas’, the legal designation used to localise emergency powers in Kashmir and Northern Ireland. It focuses on the designation as a political euphemism, and on the ways literary texts reconstitute the realities and lived experiences that these …

Initial Revegetation Of Small But Severely Disturbed Areas In The Oak-Hickory Forest Of Southwest Missouri
Five landing decks which were disturbed by bulldozers during logging operations were observed in order to study the initial stages of plant community development in an Oak-Hickory forest. The soil was disarranged to a ten centimeter depth, destroying roots and above ground vegetation. The areas …

Aspects of the revegetation of mountain fynbos vegetation of the south western Cape, South Africa
The revegetation of severely, disturbed areas using indigenous vegetation forms the topic of this thesis. Mountain Fynbos was chosen for the study because of its importance as a unique vegetation-type worthy of conservation. Unfortunately, this vegetation faces long-term threats associated with …

Survey of the Native and Nonnative Vascular Plant Species of Three Islands in Lake Winnipesaukee, New Hampshire
… trees and shrubs, dominance ratings, and basal areas. This study also focused on plants of interest including certain rare (Rhododendron maximum), introduced (Halesia carolina) and potentially invasive species (Poa compressa). Data from the study shows that the species richness on all the …

Breeding bird populations in relation to the vegetation structure of abandoned contour mines in Southwest Virginia
Twelve study areas on abandoned contour mines in southwest Virginia were surveyed to investigate relationships between breeding bird population parameters and structural aspects of the disturbed area vegetation. The territorial mapping method was employed to census bird populations. The number of …

The Vascular Flora of Camp Crowder: an Army National Guard Military Installation in Newton County, Missouri
… Stream bank, Prairie remnant, Grassland and Disturbed Areas. An effort was made to account for the occurrence of the flora within this area of southwestern Missouri in relation to the climate, topography, geology, soils, and past vegetational history. Some rare and endangered plant species …

Disturbance in Small, Fragmented Peat Bogs and its Contribution to Iris pseudacorus Colonisation
… invasive species. I. pseudacorus individuals in disturbed and undisturbed sections of the bog’s periphery were counted and compared, and buffer zone widths between Cook Road and the bog were measured. I. pseudacorus numbers were significantly higher in disturbed areas. Areas of the bog beside …

Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
… that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed production, viability and germination of poison hemlock seed were measured. Dry biomass of poison hemlock was measured through …

Is local plant extinction a product of mutualism breakdown? A case study of the Namaqualand spring flora
… plant species compositions between adjacent disturbed and undisturbed sites in a Namaqualand flowering community. It was found that autogamous annuals were at the lowest risk of extinction and were consequently abundant in disturbed lands. Geophytes were completely eliminated by ploughing, …

Impacts of timber harvesting on soil physical properties in wetlands
… of 3 sites (blocks) and trafficked and undisturbed areas were sampled on each site. Effects of trafficking on soil physical properties and hydrology were tested by comparing the disturbed (trafficked) and undisturbed subplots. Traffic increased bulk density and decreased soil porosity …

Cheatgrass (Bromus tectorum L.) management and native plant community recovery on sites selectively treated with Imazapic in Rocky Mountain National Park
… Park (RMNP). Cheatgrass aggressively invades disturbed sites and competes with native plant species by rapidly establishing a root system capable of depleting soil moisture and available nitrogen, making cheatgrass control a priority when restoring disturbed areas within RMNP. The purposes of …

Limnological And Landscape Factors Affecting Use Of Manufactured Ponds By The Invasive Cuban Treefrog (Osteopilus Septentrionalis)
… them for resources. Cuban Treefrogs thrive in disturbed areas and around buildings, and often breed in manufactured wetlands such as retention ponds and borrow pits. This study identified limnological, landscape, and biotic characteristics that discouraged pond use by Cuban Treefrogs and …

The influence of elevated arsenic concnetrations on stream biota and leaf breakdown in a headwater stream
… which is toxic to aquatic biota especially in disturbed areas where it may be found at high concentrations. A headwater stream adjacent to an 85 year-old abandoned arsenic mine was investigated to determine the influence of arsenic on stream biota and processes using an upstream (reference) and …

Exotic Invasive Plants on Private Woodlands of Virginia: Effects on forest composition, structure, and wildlife habitat
… and altering wildlife habitat, especially in disturbed areas. Disturbance, including access roads, trails, harvest sites, powerline corridors, and fence rows, is common on private land. Private landowners are often left to combat these problems without many monetary or expertise resources that …

Effects of Forest Fragmentation on Central Amazonian Bird Demography
… on the persistence of species in cleared and disturbed areas. Regenerating forest facilitates bird dispersal within degraded Amazonian landscapes and may tip the balance in favor of persistence in previously depauperate habitat patches. Despite the potential value of Amazonian second growth, …

Effects of an intermediate-scale wind event on forest composition, structure, and structural complexity
… tracked 5 km, leaving a patchwork mosaic of disturbed areas. To analyze the intra-stand spatial patterns of tree morality and biological legacies after an intermediate-scale wind disturbance, I established a 100 × 200 m (2 ha) rectangular plot perpendicular to the path of the storm within an …

Chimpanzee conservation in light of impending iron ore mining project in SE Senegal
… populations will likely be displaced from areas of suitable habitat. To understand the effects of human disturbances on chimpanzee populations prior to mining, as well as chimpanzee habitat use and behaviors, I collected survey data at two study sites that have been identified by mining …

Investigation of the relationships between biomass reduction, soil disturbance, soil nutrients and weed invasion in basalt plains native grassland remnants in Victoria, Australia
… of exotic and native plant growth in intact and disturbed areas. The successful establishment of native species during revegetation, with low levels of weed growth, will depend on the extent to which below ground growth of natives is achieved to lower available nutrient levels quickly, and …
