Monitoring Soft-Mast Production In Pine Woodland Restoration Areas On The Ouachita National Forest, Tamara B. Wood

Electronic Theses and Dissertations

The use of prescribed fire is integral to the restoration of open woodland habitats in the southeast, including shortleaf pine (Pinus echinata) woodlands in the Ouachita Mountains. Mature pine habitats maintained with recurrent disturbances have an open understory with a rich floristic diversity that provides quality habitat for many wildlife species, including the endemic and endangered red-cockaded woodpecker (Picoides borealis). Fire has many potential benefits for wildlife; however, the effects of fire on several important woody soft-mast producing species are not fully understood. Soft-mast quantity and quality is a key component in determining year-round habitat quality …

Estimating Wildlife Biodiversity Of Pine Plantation Edges Of Contrasting Rotational Stages: A Case Study, Joshua Perry Harris

ESTIMATING WILDLIFE BIODIVERSITY OF PINE PLANTATION EDGES OF CONTRASTING ROTATIONAL STAGES: A CASE STUDY

By: Joshua Harris, Dr. Daniel Scognamillo, Dr. Gary Kronrad, and Dr. Jeremy Stovall

Abstract

Wildlife biodiversity was estimated amongst three loblolly pine (Pinus taeda) intra-plantation edge types of contrasting rotational phases in a two-year case study. Three structurally varied rotational phases that occur throughout plantation rotations combine to make three different edges: A= pre-thinned - post-thinned, B= pre-thinned - pre-clearcut, and C= post-thinned - pre-clearcut. For two summer seasons (May-August 2015-2016), invertebrates, birds, medium mammals, and small mammals were sampled in each edge type. …

Evaluating Mine Soil Prepared By Scraper Pans For Herbaceous Plants And Pine Seedlings At An East Texas Lignite Surface Mine, Hannah Z. Angel

Electronic Theses and Dissertations

Since 1974, Luminant Mining Company, LLC (Luminant) has planted over 38.7 million trees on its reclaimed lignite surface mine operations in Texas. For decades, the use of improved reclamation techniques on Luminant’s mined lands have resulted in over 31,160 ha reclaimed to forests, wildlife habitat, and pastures with productivity levels similar to those found on unmined lands. The development of new reclamation methodologies offers opportunities to further improve productivity of planted trees at Luminant’s Martin Lake Oak Hill Mine in east Texas. The conventional haulback or ‘truck shovel’ reclamation method uses haul trucks for the selective transport and placement of …

Quality And Yield Responses Of Seven Warm Season Forage Grasses To Partial Shading In A Simulated Silvopasture In East Texas, Jodi E. Hill

Electronic Theses and Dissertations

The goal of this project was to evaluate growth and nutritional characteristics of seven forages, including various warm season native grasses, grown under simulated partial shading (50%) typical of a loblolly pine silvopastoral system in East Texas. In order to meet the overall objective, slatted shade structures were constructed that simulated the quantity, quality, and overall light regime found beneath loblolly pine stands arranged for silvopasture. The forages selected for the study included ‘Tifton 9’ bahiagrass (Paspalum notatum), ‘Tifton 85’ bermudagrass (Cynodon dactylon), ‘Alamo’ switchgrass (Panicum virgatum), ‘Kaw’ Big Bluestem (Andropogon gerardii), ‘Americus’ …

Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques

Electronic Theses and Dissertations

Interest in bottomland hardwood forests (BLHW) ecology and restoration has increased over the past 40 years. These communities aid in water quality improvement, streambank stabilization, and urban expansion mitigation. They also provide important habitat for many species of wildlife. Since the majority of remaining BLHW are degraded due to land fragmentation, restoration attempts are becoming commonplace within the Western Gulf Coastal Plain. However, restoration success has been mixed, with managers observing survival rates of <15% for desirable species due to various factors. Over two growing seasons, I investigated multiple factors that have potential to limit BLHW restoration success in East Texas. Specifically, I tested the impacts of herbivory by white-tailed deer (Odocoileus virginianus) and feral swine (Sus scrofa) on Nuttall oak (Quercus texana Buckley), Shumard oak (Q. shumardii Buckley), bur oak ( …
