The Long-Term Effects Of Wildfire Severity On Oak-Pine Communities And Their Microclimates, Scott Glenn Culbert
The Long-Term Effects Of Wildfire Severity On Oak-Pine Communities And Their Microclimates, Scott Glenn Culbert
Theses and Dissertations--Forestry and Natural Resources
In the eastern U.S., fire-dependent tree species have historically dominated upland forest communities, but are now experiencing widespread regeneration challenges as a result of 20th century fire suppression policies, and are being replaced by mesophytic species. Wildfires that contain areas of high burn severity may provide an important means of mitigating these challenges and facilitating fire-dependent species regeneration and recruitment into larger size classes. One mechanism by which high-severity fire can accomplish this is by modifying understory microclimate characteristics to be more conducive to these species’ growth. A wildfire within the Daniel Boone National Forest, Kentucky, USA, provided the …
Pond-Breeding Amphibian Responses To Wetland Creation And Reforestation On A Legacy Surface Mine In The Monongahela National Forest, Lauren Breanna Sherman
Pond-Breeding Amphibian Responses To Wetland Creation And Reforestation On A Legacy Surface Mine In The Monongahela National Forest, Lauren Breanna Sherman
Theses and Dissertations--Forestry and Natural Resources
Surface mine reclamation has been an evolving practice since the Surface Mining Control and Reclamation Act was passed in 1977, holding mining companies accountable for returning ecological function to areas directly impacted by mining activities. One recent method of reclamation, the Forestry Reclamation Approach (FRA), aims to enhance reforestation and ecosystem function through the creation of wetlands, as opposed to traditional methods that often revert land to grasslands. However, wildlife response to FRA has rarely been investigated. The goal of this project was to analyze the effects of the four treatment types, FRA in two chronosequences, natural regeneration, and unmined …
Effects Of Forest Reclamation And Landscape Features On Avian Occupancy, Species Richness, And Abundance In Appalachia, Rebecca N. Davenport
Effects Of Forest Reclamation And Landscape Features On Avian Occupancy, Species Richness, And Abundance In Appalachia, Rebecca N. Davenport
Theses and Dissertations--Forestry and Natural Resources
The Forestry Reclamation Approach (FRA) is a recently developed coal mining reclamation method that emphasizes best management practices in forestry, such as the planting of native trees and shrubs. Although the FRA is expected to benefit wildlife, no studies have empirically examined the effects of the FRA on avian species. My study aimed to identify which reclamation approaches and/or landscape features promote breeding songbirds, particularly mature forest avian guilds and species of conservation need. I conducted point count surveys in the Appalachian Mountains of eastern West Virginia and assessed differences in avian occupancy, species richness, and species abundance between four …
Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese
Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese
Theses and Dissertations--Forestry and Natural Resources
Kentucky’s disappearing native grassland communities provide habitat for native flora and fauna. A study was conducted to compare the efficacy of herbicides in control of the invasive Japanese honeysuckle (Lonicera japonica) applied at times when most native species are dormant. Six herbicide mixtures (glyphosate, glyphosate + imazapyr, glyphosate + imazapic, imazapyr, triclopyr + difluphenzopyr, and metsulfuron + difluphenzopyr) were applied in three seasons to assess the effect of application timing of each mixture on honeysuckle control. Herbicides were applied with a CO2 pressurized sprayer at three sites in a randomized complete block design. Pretreatment sampling indicated that …
