Effects Of Canopy And Cultural Treatments On Fine Fuel Production, Fire Behavior, And Short-Term Fire Effects In Loblolly Pine (>I/I< L.) Stands Being Restored To Longleaf Pine (>I/I< Mill.), Carsyn Tennant
All Theses
Across the southeastern United States, anthropogenic factors such as land conversion and fire suppression have resulted in the prevalence of loblolly pine in areas historically occupied by longleaf pine. Compared to longleaf pine forests, loblolly stands often contain a substantial broad-leaved midstory and lack the ground layer that contributes fuels essential for the frequent, low intensity surface fire regime necessary to sustain the longleaf ecosystem. Currently, there is considerable interest in restoring longleaf pine habitats to areas occupied by loblolly pine. The retention of mature canopy trees is often necessary to maintain ecosystem function, to preserve habitat features, and to …
Restoring Longleaf Pine (Pinus Palustris) In Loblolly Pine (P. Taeda) Stands On The Coastal Plain Of North Carolina, Huifeng Hu
All Dissertations
To support the development of silvicultural protocols for restoring longleaf pine (LLP; Pinus palustris Mill.) and its characteristic herbaceous understory in loblolly pine (LBP; P. taeda L.) stands, a three-year study was conducted on moderately well- and well-drained soils in Onslow County, North Carolina. A replicated field experiment was conducted to test the effects of selected silvicultural treatments on planted LLP seedlings, understory vegetation, and plant resources. Seven canopy treatments included four uniform canopy density treatments defined by target residual basal area [Control, MedBA (9 m2/ha), LowBA (4.5 m2/ha), and Clearcut] and three circular gap treatments defined by area [LG …
Silvicultural Considerations For The Reintroduction Of American Chestnut, Castanea Dentata, To The Forests Of The Eastern United States, Cornelia Cooper Wells Pinchot
Silvicultural Considerations For The Reintroduction Of American Chestnut, Castanea Dentata, To The Forests Of The Eastern United States, Cornelia Cooper Wells Pinchot
Doctoral Dissertations
In anticipation of widespread planting of putatively blight-resistant hybrid chestnuts (Castanea spp.), it is critical to understand the silvics and competitive ability of the species. This dissertation examines preliminary growth and survival of several species and genetic crosses of chestnut grown as 1-0 high-quality nursery seedlings and planted in two study sites: Southeastern Kentucky (Daniel Boone National Forest; chapter 2), and Northeastern Connecticut (Yale-Myers Forest; chapter 4). The effects of three silvicultural treatments on the Daniel Boone National Forest (DBNF), and four silvicultural treatments on the Yale-Myers Forest (YM) were evaluated. Furthermore, the effect of initial seedling size on …
Mycorrhizal Colonization Of Native Salt Marsh Plants On Mississippi's Gulf Coast And The Effects Of Commercial Mycorrhizal Inoculants On Nursery-Grown Plants, Kathryn Rondot Mcbride
Mycorrhizal Colonization Of Native Salt Marsh Plants On Mississippi's Gulf Coast And The Effects Of Commercial Mycorrhizal Inoculants On Nursery-Grown Plants, Kathryn Rondot Mcbride
Master's Theses
Salt marshes are important economically and ecologically to the Gulf Coast and other coasts worldwide. Due to human activities, many coastal salt marshes have been degraded or destroyed. Restoration efforts, through the replacement or addition of naturally occurring salt marsh plants, are taking place worldwide. Most restoration plants are raised in nurseries and are not ready for transfer to restoration sites for eight or nine months. Once the plants are at the restoration site many die due to transplant stress. Arbuscular Mycorrhizal Fungi (AMF) may be able to shorten the time the restoration plants need to stay in the nursery …
