Dissertation/Thesis Abstract

Wildlife Road Mortalty Survey Methodologies
by Livingston, Trinity Dale, M.S., The University of Texas Rio Grande Valley, 2019, 78; 22618806
Abstract (Summary)

Wildlife mortality due to vehicle collisions is detrimental to species with slower reproduction times, habitat specialists, low density populations, species with large home ranges, or rare species. Vehicle-caused wildlife mortality is an important conservation issue, but before we can ameliorate the effects of road mortalities, we must understand what why it is happening. Wildlife road mortality surveys may be conducted in several ways based on the target species, time available, finances, and safety. Survey methodologies include using accident reports by police and warden agencies, pedestrian road surveys, using citizen scientists, and driving surveys. These methods present a safety risk to the surveyor and or may result in erroneous identifications in the case of citizen scientists. Over the course of this study a safer, novel action camera-based methodology was developed. This study determined the optimal survey frequency, based on wildlife mortality data and calculations of persistence rates.
