Item Effect of fire on forbs and grasses in the Texas Coastal prairie(Texas Tech University, 1983-05) Hansmire, Julie ANot availableItem Nesting habitat selection of wood ducks and non-game cavity nesting birds in the northern rolling plains of Texas(Texas Tech University, 1998-12) Magill, Robert ThomasWood ducks (Aix sponsa) and non-game cavity nesting birds have expanded their range westward along some riparian zones in the Great Plains following the maturation of plains Cottonwood (Populus deltoides) habitat. Wood ducks and other cavity nesting birds nest locally in the Northern Rolling Plains of Texas, however information on habitat selection is not available for any of these species. I evaluated habitat characteristics that potentially influence nest site occupancy and nest success of cavity nesting birds.Item Restoration of riparian wildlife habitat in the middle Rio Grande Valley following historical river hydrographs(Texas Tech University, 1999-05) Sprenger, Matthew D.Native cottonwood-willow (Populus spp.- Salix spp.) riparian forests are important in maintaining regional biodiversity in the semi-arid and arid southwestern United States. Though these areas comprise only a small proportion of the landscape compared to adjacent upland areas, they support a greater diversity of vertebrate species. Declines in native riparian woodlands have resulted in an intensified effort to develop ways to restore these habitats. Degradation of native riparian habitat has resulted from changes in river hydrology and the introduction of saltcedar (Tamarix ramosissima). an exotic woody shrub. Saltcedar is well adapted to the altered hydrology of many southwestern rivers and has replaced native vegetation. Saltcedar woodlands are less valuable to most wildlife species compared to native vegetation. To successfully restore native woodlands in southwestern riparian areas, methods to control or remove existing saltcedar must be developed in conjunction with methods to restore native woody species.Item Winter and spring habitat selection by mature, male white-tailed deer in southern Texas(Texas Tech University, 1989-08) Pollock, Matthew ToddBecause of the economic value of white-tailed deer to the state of Texas and the potential of brush management strategies for altering deer habitat negatively, a study was developed to determine vegetative characteristics influencing site selection by mature^ male white-tailed deer, and to quantify habitat preferences for selected habitat variables during winter and spring in southern Texas. Fourteen mature, male white-tailed deer were radiocollared and monitored during winter (1 December - 28 February) and spring (1 March - 31 May) seasons of 1986-87 and 1987-88. Telemetry locations of individual animals were integrated with a computer-generated grid system (2.25-ha cells) of the study area to quantify relative usage of each grid cell. The most heavily used cell and an adjacent unused cell were identified for each animal on a seasonal basis. Contrasts of structural vegetative characteristics were made between the most heavily used cell and an adjacent unused cell. Of the vegetation contrasts, high woody species richness, dense horizontal screening cover, and canopy cover that exceeded 75% all appeared to have a positive influence on site selection by mature, male white-tailed deer in winter and spring.
