An Investigation Into Historical And Contemporary Breeding Occurrence Of The Ferruginous Hawk In Kansas, Erica Clark Jan 2021

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 …


The Effect Of Vegetative Structure On Nest-Burrow Selection By The Western Burrowing Owl: Comparing Traditional Methods To Photogrammetry With An Unmanned Aerial System, Dylan J. Steffen Jan 2019

The Effect Of Vegetative Structure On Nest-Burrow Selection By The Western Burrowing Owl: Comparing Traditional Methods To Photogrammetry With An Unmanned Aerial System, Dylan J. Steffen

Master's Theses

The shortgrass prairie ecoregion in the United States has been reduced to 52% of its historical extent, contributing to reduced habitat for native species. One such species is the Burrowing Owl (Athene cunicularia). The Western Burrowing Owl subspecies (A. c. hypugaea) is listed as a Species of Special Concern in nearly every western and midwestern state, including Kansas where it is designated as a Tier II Species of Greatest Conservation Need. Habitat destruction due to conversion to cropland, increasing use of pesticides, and reduction in burrowing mammal abundance are the primary threats that have led to …


An Aerial Perspective: Using Unmanned Aerial Systems To Predict Presence Of Lesser Earless Lizards (Holbrookia Maculata), Sean Rogers May 2018

An Aerial Perspective: Using Unmanned Aerial Systems To Predict Presence Of Lesser Earless Lizards (Holbrookia Maculata), Sean Rogers

Master's Theses

Implementation of unmanned aerial system (UAS) in conservation biology has allowed researchers to extend their surveying range for monitoring wildlife. Wildlife biologists have started using UAS technology for detecting large species (i.e. elk, manatees) within their surveying range and monitoring changes and disturbance in the landscape. Despite this technological advancement, there are few studies that target smaller species (reptiles, rodents, amphibians) for UAS surveys. The primary reason for this is that these organisms are simply too small for detection for aerial surveying. However, certain species are restricted in their range because they have specific environmental requirements, and the target for …
