Predicting Northern Bobwhite Habitat In Semiarid Rangeland Using Landsat Imagery, Jeffrey G. Whitt, Kelly S. Reyna
Predicting Northern Bobwhite Habitat In Semiarid Rangeland Using Landsat Imagery, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Multiple studies have attempted to model northern bobwhite (Colinus virginianus) distribution using classified remotely sensed imagery in combination with pattern recognition software. These models tend to be more accurate in humid subtropical regions. To identify bobwhite habitat in subhumid and semiarid rangeland, we performed our own classification on 4 LANDSAT scenes of Clay County, Texas, from July and December 2015. Stands of mature little bluestem (Schizachyrium scoparium) provide excellent bobwhite nesting cover and could be identified using LANDSAT imagery. Habitat was scored from 0 to 1.0 based on estimated range health, presence of little bluestem, and …
Conservation Reserve Program Grasslands And Ring-Necked Pheasant Abundance In Minnesota, James F. Drake, Richard O. Kimmel, J. David Smith, Gary Oehlert
Conservation Reserve Program Grasslands And Ring-Necked Pheasant Abundance In Minnesota, James F. Drake, Richard O. Kimmel, J. David Smith, Gary Oehlert
National Quail Symposium Proceedings
Ring-necked pheasant (Phasianus colchicus) abundance was measured on 15 study areas using roadside counts during the summers of 1990-1994 to examine possible relationships to permanent grasslands and 9 other cover types. The majority of permanent grasslands was enrolled in the Conservation Reserve Program (CRP) and likely would have been actively used for agriculture if not for the CRP. Roads were divided into 300 m segments and the proportion of each cover type was determined within 200 m and 800 m of each segment. A non-parametric procedure was used to determine the most significant predictors of number of pheasants observed on …
Delineation Of Gambel's Quail Habitat In The Trans-Pecos, Texas, Alfonso Ortega-Sanchez, Louis A. Harveson, Roel R. Lopez, Michael R. Sullins
Delineation Of Gambel's Quail Habitat In The Trans-Pecos, Texas, Alfonso Ortega-Sanchez, Louis A. Harveson, Roel R. Lopez, Michael R. Sullins
National Quail Symposium Proceedings
Gambel’s quail (Callipepla gambelii) are a common quail species in southwestern states of the United States and the northwestern states of Mexico. In Texas this species occurs in the Trans-Pecos region, are underutilized, and could become an important game bird and source of income for ranchers in the Chihuahuan Desert region of Texas. Salt cedar (Tamarisk spp.), introduced from Asia for ornamental and erosion purposes, is invasive in the western part of the Rio Grande corridor that generally creates monocultures that choke out the native vegetation of the region. Knowing this, the objectives of this study were to: (1) delineate …
Streambank Erosion Mapping On The Nottoway River Using Gps-Based Above-Water Video, Emine Fidan
Streambank Erosion Mapping On The Nottoway River Using Gps-Based Above-Water Video, Emine Fidan
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
This project concerns the development of streambank erosion maps on military installations utilizing GPS-based above-water video mapping and image georeferencing techniques. The river mapped was the Nottoway River at the Fort Pickett military installation on October 10-11, 2015. Kayak-mounted above-water cameras were utilized to capture georeferenced images of streambank erosion. These GIS-based erosion classifications were utilized to develop erosion maps for determining streambank erosion conditions along the river. Areas of high erosion were identified as about two percent of the river (2167 ft. of streambank length). These maps allow for the opportunity to revisit the sites to determine changes in …
