Theses and Dissertations--Forestry and Natural Resources
Three small (< 1 ha) mountain wetlands located in eastern Kentucky, host populations of two rare orchids, the white fringeless orchid, Platanthera integrilabia, and the crested yellow orchid, Platanthera cristata. Recently, concern has arisen about the persistence of the orchids. To better understand these wetlands and determine if hydrology is affecting the orchid populations, a hydrologic characterization study was initiated in 2009. Each wetland was equipped with a well nest consisting of piezometers, tensiometers, and a shallow well with a data logging pressure transducer. Chemistry and stable isotopes analysis (deuterium and 18O) of groundwater and precipitation were analyzed, and soil, topographic and channel cross-section surveys were conducted. Hydrology data suggest the primary source of water …

Effects Of Midstory Removal And Shoot Clipping On The Growth And Development Of Three Oak Species, Jared Matthew Craig
Theses and Dissertations--Forestry and Natural Resources
Problems developing tall oak seedlings of high abundance have become a concern throughout many eastern hardwood forests. The decline in oak seedling recruitment into canopy positions is often attributed to the increasing abundance of shade tolerant midstory species, especially red maple (Acer rubrum L.). Studies have shown that increasing light to the understory by way of a midstory removal has the ability to favor oak seedlings over competitors. The majority of studies to date have examined northern red (Quercus rubra L.) and cherrybark oak (Quercus pagoda Raf.) on productive sites, but relatively little is …

A Comparison Of Noninvasive Survey Methods For Monitoring Mesocarnivore Populations In Kentucky, Bryan Matthew Tom
Theses and Dissertations--Forestry and Natural Resources
Harvest data are typically used to evaluate mesocarnivore population dynamics in many states, including Kentucky. While relatively easy to collect, these data are subject to reporting biases, and inferences about population trends can often only be made at coarse spatial scales. Gray fox (Urocyon cinereoargenteus), bobcat (Lynx rufus), and coyote (Canis latrans) populations in Kentucky are managed primarily through harvest data used to establish future harvest quotas. Increasingly, noninvasive survey methods have been used to characterize a number of population parameters for a variety of species; however, successful use of these methods is often …
