A Karst Feature Prediction Model For Prince Of Wales Island, Alaska Based On High Resolution Lidar Imagery, Alexander Lyles
A Karst Feature Prediction Model For Prince Of Wales Island, Alaska Based On High Resolution Lidar Imagery, Alexander Lyles
Master's Theses
Investigation into surface karst formation is significant to hazard prediction, hydrogeologic drainage, and land management. Southeast Alaska contains over 600,000 acres of mapped carbonate bedrock, and some of the fastest recorded karst dissolution in the world. The objectives of this study are to develop and compare multiple semi-automated models to map and delineate karst features from bare-earth LiDAR imagery using ArcGIS Desktop 10.7, and to apply a preliminary geostatistical analysis of sinkhole morphometric parameters to highlight potential spatial patterns of karst evolution on Prince of Wales Island, Alaska. A semi-automated approach of mapping karst features provides a dataset that minimizes …
An Investigation Into Historical And Contemporary Breeding Occurrence Of The Ferruginous Hawk In Kansas, Erica Clark
An Investigation Into Historical And Contemporary Breeding Occurrence Of The Ferruginous Hawk In Kansas, Erica Clark
Master's Theses
The Ferruginous Hawk (Buteo regalis) is the largest Buteo species occurring in grasslands, nesting along bluffs, buttes and isolated trees. In Kansas, the Ferruginous Hawk is listed as a Species of Greatest Conservation Need, Tier II. A previous study on Ferruginous Hawks nesting in Kansas during the years of 1979 to 1987, with sporadic visits from the 1990s to 2000, revealed that the most productive nesting territories were inaccessible to predators, placed on rocky ledges and the surrounding landscape was over 50% rangeland. I revisited 82 of the 111 historic nest territories in the summers of 2019 and …
