Effects Of Prescribed Fire Regimes On White-Tailed Deer (Odocoileus Virginianus) Browse, Forage, And Nutrient Availability In The Pineywoods Ecoregion Of Texas, Wyatt L. Bagwell
Effects Of Prescribed Fire Regimes On White-Tailed Deer (Odocoileus Virginianus) Browse, Forage, And Nutrient Availability In The Pineywoods Ecoregion Of Texas, Wyatt L. Bagwell
Electronic Theses and Dissertations
Fire is a management tool for white-tailed deer (Odocoileus virginianus) habitat, influencing browse availability, herbaceous production, and nutrient content. In 2020 and 2021, this study utilized 46 plots across East Texas to assess these habitat components. A stem count index survey method was used to assess browse utilization prior to April in both years, and preferred browse species were clipped and analyzed for nutrient availability, and herbaceous production was also measured. Additionally, white-tailed deer population data, browse survey data, and recent fire history were obtained from five different wildlife management areas to examine their relationship. Deer had preferences …
Microsite Requirements For Successful Regeneration In Lowland Northern White-Cedar (Thuja Occidentalis) Forests, Jeanette Allogio
Microsite Requirements For Successful Regeneration In Lowland Northern White-Cedar (Thuja Occidentalis) Forests, Jeanette Allogio
Electronic Theses and Dissertations
Declines in stands of northern white-cedar (Thuja occidentalis L., hereafter cedar) have been observed as both shifts in species composition and reductions in cedar densities, particularly those stands in lowland sites (Curtis 1946, Boulfroy 2012). While several factors inhibiting cedar regeneration have been identified, a thorough understanding of the conditions that best promote regeneration is lacking. Our objectives for the first chapter were to characterize the site conditions associated with successful regeneration in lowland cedar stands and to describe how spatial patterns of various cedar size classes relate to site preference and to regeneration dynamics. These objectives were achieved …

Ungulate herbivory occurring within a forest plant community’s natural range of variation may help maintain species diversity. However, acute or chronically elevated levels of herbivory can produce dramatic changes in forest communities. For example, chronically high levels of herbivory by white-tailed deer (Odocoileus virginianus Zimmerman) in regions of historically low abundance at northern latitudes have dramatically altered forest community composition. In eastern hemlock (Tsuga canadensis L. Carrière) stands where deer aggregate during winter, high deer use has been associated with a shift towards deciduous species (i.e., maples [Acer spp.]) dominating the regeneration layer. Especially harsh winters can lead to deer …

First-Year Vitality Of Reforestation Plantings In Response To Herbivore Exclusion On Reclaimed Appalachian Surface-Mined Land, Zachary J. Hackworth, John M. Lhotka, John J. Cox, Christopher D. Barton, Matthew T. Springer

Conventional Appalachian surface-mine reclamation techniques repress natural forest regeneration, and tree plantings are often necessary for reforestation. Reclaimed Appalachian surface mines harbor a suite of mammal herbivores that forage on recently planted seedlings. Anecdotal reports across Appalachia have implicated herbivory in the hindrance and failure of reforestation efforts, yet empirical evaluation of herbivory impacts on planted seedling vitality in this region remains relatively uninitiated. First growing-season survival, height growth, and mammal herbivory damage of black locust (Robinia pseudoacacia L.), shortleaf pine (Pinus echinata Mill.), and white oak (Quercus alba L.) are presented in response to varying intensities …

Wilderness areas are often considered quality areas where natural processes occur without human activity. It is often assumed that these unmanaged areas will provide and support quality wildlife habitat. The objective of this study was to evaluate the forage production and stocking potential of an unmanaged wilderness area in east Texas. Four different community types were evaluated for forage yield, forage availability, and browse utilization for white-tailed deer. Results show that although a wide range of forage yields were measured in the spring, summer forage yield did not differ among the various communities. Availability also differed between community types, but …

T: Quaking aspen (Populus tremuloides) forests are experiencing numerous impediments across North America. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. Additionally, ecological tension zones are sometimes created at residential-wildland interfaces with divergent management directives. For example, private conservation reserves bordering public land may be degraded from browsing where game species find refuge from hunting and plentiful forage. We examined putative herbivore impacts to nearly pure aspen forests at Wolf Creek Ranch (WCR), a sparsely developed residential landscape in northern Utah. Forty-three one-hectare monitoring …
Seedling Uptake And Fate Of Soil-Applied Capsaicin, A Potential Browse Deterrent, Carmen K. Dobbs, Joshua L Sloan, Douglass F. Jacobs
Seedling Uptake And Fate Of Soil-Applied Capsaicin, A Potential Browse Deterrent, Carmen K. Dobbs, Joshua L Sloan, Douglass F. Jacobs
The Summer Undergraduate Research Fellowship (SURF) Symposium
Seedling damage due to browse constitutes a major challenge to afforestation and reforestation efforts in the Central Hardwood Forest region of the USA. Many efforts have been made to deter herbivores, but the costs, implementation methods, and relative ineffectiveness of existing mitigation options often preclude operational implementation. An alternate means of deterring wildlife browse is capsaicin, a hot pepper concentrate, which has been reported to decrease herbivory of tree seedlings and is available in a controlled-release form designed to act systemically following application to the soil and subsequent plant uptake. However, the degree to which seedlings are capable of absorbing …

Quaking aspen (Populus tremuloides Michx.) forests are experiencing numerous impediments across North America. In the West, recent drought, fire suppression, insects, diseases, climate trends, inappropriate management, and ungulate herbivory are impacting these high biodiversity forests. Additionally, ecological tension zones are sometimes created where the above factors intermingle with jurisdictional boundaries. The public-private land interface may result in stress to natural areas where game species find refuge and plentiful forage at the expense of ecosystem function. We examined putative herbivore impacts to aspen forests at Wolf Creek Ranch (WCR), a large residential landscape in northern Utah. Forty-three ha-1 monitoring plots were …
Logging In Alaska's Boreal Forest: Creation Of Grasslands Or Enhancement Of Moose Habitat, William B. Collins, Charles C. Schwartz
Logging In Alaska's Boreal Forest: Creation Of Grasslands Or Enhancement Of Moose Habitat, William B. Collins, Charles C. Schwartz
Aspen Bibliography
Timber harvest in Alaska’s boreal forest can greatly enhance or severely reduce moose (Alces alces) habitat quality, depending on forest management objectives, timing and methods of harvest, and post-logging site preparation. Overstory removal associated with timely exposure of mineral soil favors establishment of early successional hardwoods important as moose browse. A combination of clear-cutting and soil scarification on mesic sites mimics fire, windfall, and fluvial erosion, important natural forces that drive regeneration of the boreal forest. When cut during dormancy, aspen (Populus tremuloides) and balsam poplar (P. balsamifera) Regenerate prolifically by root and stump …

Aspen Bibliography
Grazing impact by elk and moose has been a point of concern in Jackson Hole for many years. Concern has been primarily directed towards sparsely vegetated south aspects, aspen stands, and willow bottoms. Numerous transects have quantified heavy foliage utilization. Trend studies have been mostly inconclusive. Study of historical narratives have quantified heavy forage utilization. Trend studies have been mostly inconclusive. Study of historical narratives, early photographs and consideration of plant physiology, soils data, and fire ecology have aided interpretations of vegetal trend and plant succession in recent years. Photographs show little change on sparsely vegetated sites. Soils information on …
