Paddlefish populations have begun to decline throughout their historic range but are still found in 22 states in the southeastern and midwestern United States. This capstone project investigates problems facing paddlefish management including, pollution, habitat loss, poaching, and the illegal caviar trade. A combination of four management options is beneficial for the species by increasing public knowledge and awareness of what paddlefish require for survival, allowing paddlefish to be used as a natural resource. After comparing a typical state paddlefish management plan and the plan developed and used in Missouri, it is apparent that a national paddlefish management plan template is necessary for affected states. A plan provides direction for effectively maintaining paddlefish stocks, according to state specific management goals.

The Adams County Regional Park and Fairgrounds must comply with environmental policies related to surface water and groundwater protection. This paper assesses various methods which have proven to be effective in the reduction of nutrients and other contaminants found in surface and groundwater at comparable livestock-based venues. Data was gathered from other facilities in order to identify specific compliance alternatives and evaluate management options. Empirical research, coupled with GIS mapping technology yielded explicit water quality management recommendations for the Adams County Regional Park and Fairgrounds. The outcome of this research and mapping exercise include twelve management recommendations and two site-specific locations for structural BMPs designed to better control water pollution at the Adams County Regional Park and Fairgrounds.

Chronic wasting disease is a fatal neurological disease found in deer and elk in 14 western and mid-western states and two Canadian provinces. It is believed to have been first observed in Colorado and Wyoming in 1967. It is a disease caused by prions by an unknown transmission vector and impossible to cure at this time. Most of the management options currently available are labor-intensive and costly. The potential use of controlled burns to reduce or eliminate the prions that cause the disease was shown to have no effect on the prevalence of the disease in either study area. The temperatures needed to destroy prions were not reached by either surface or crown fires.
