Restoring Semi-Arid Thornscrub Forests: Seeding Growth And Survival In Response To Shelter Tubes, Grass-Specific Herbicide, And Herbivore Exclosures, Krysten Noelle Dick
Restoring Semi-Arid Thornscrub Forests: Seeding Growth And Survival In Response To Shelter Tubes, Grass-Specific Herbicide, And Herbivore Exclosures, Krysten Noelle Dick
Theses and Dissertations - UTB/UTPA
This thesis is a compilation of two studies, which I have called ‘chapters.’ The first chapter, “Restoring Semi-Arid Thornscrub Forests: Seedling Growth and Survival in Response to Shelter Tubes, Grass-Specific Herbicide, and Herbivore Exclosures,” was a large study involving multiple techniques used to improve revegetation success, and the second chapter, “Shelter Tube Effects on Microclimate and Seedling Growth in Semi-arid Thornscrub Forests,” focused on the use of shelter tubes in semi-arid forest revegetation. These studies were concurrent evaluations of restoration efforts in thornscrub forests of South Texas. Revegetation is a common effort used to restore forest ecosystems that have been …
Consequences Of Pre-Inoculation With Native Arbuscular Mycorrhizae On Root Colonization And Survival Of Wyoming Big Sagebrush (Artemisia Tridentata Ssp. Wyomingensis) Seedlings After Transplanting, Bill Eugene Davidson
Consequences Of Pre-Inoculation With Native Arbuscular Mycorrhizae On Root Colonization And Survival Of Wyoming Big Sagebrush (Artemisia Tridentata Ssp. Wyomingensis) Seedlings After Transplanting, Bill Eugene Davidson
Boise State University Theses and Dissertations
Inoculation of seedlings with arbuscular mycorrhizal fungi (AMF) is a common practice aimed at improving seedling establishment. The success of this practice largely depends on the ability of the inoculum to multiply and colonize the growing root system after transplanting. These events were investigated in Artemisia tridentata ssp. wyomingensis (Wyoming big sagebrush) seedlings inoculated with native AMF. Seedlings were first grown in a greenhouse in sterilized soil (non-inoculated seedlings) or soil containing a mixture of native mycorrhizae (inoculated seedlings). Three-month old seedlings were transplanted to 24 L pots containing soil from a sagebrush habitat (mesocosm experiments) or to a recently …

Extensive woodland expansion in the Great Basin has generated concern regarding ecological impacts of tree encroachment on sagebrush rangelands and strategies for restoring sagebrush steppe. This study used rainfall (0.5 m2 and 13 m2 scales) and concentrated flow simulations and measures of vegetation, ground cover, and soils to investigate hydrologic and erosion impacts of western juniper (Juniperus occidentalis Hook.) encroachment into sagebrush steppe and to evaluate short-term effects of burning and tree cutting on runoff and erosion responses. The overall effects of tree encroachment were a reduction in understory vegetation and formation of highly erodible, bare intercanopy …

Land owners and managers across the western United States are increasingly searching for methods to evaluate and mitigate the effects of woodland encroachment on sagebrush steppe ecosystems. We used small-plot scale (0.5 m2) rainfall simulations and measures of vegetation, ground cover, and soils to investigate woodland response to tree removal (prescribed fire and mastication) at two late-succession woodlands. We also evaluated the effects of burning on soil water repellency and effectiveness of aggregate stability indices to detect changes in erosion potential. Plots were located in interspaces between tree and shrub canopies and on undercanopy tree and shrub microsites. Erosion from …
