Summary of Wild Hog Research

Wild hogs are responsible for an estimated $1.5 billion to the U.S. economy each year. These losses are the result from row crop destruction (including timber), damage to property and infrastructure, and disease transmission, as well as many others. Also included in this estimate are the costs of controlling wild hogs, and in cases where applicable, eradication efforts through state and federal agencies, as well as private operations. We currently have a total of five research projects underway in regards to wild hog ecology, agricultural economics, conservation policy, and human-dimensions. One project is measuring movement patterns of wild hogs in agricultural landscapes to better understand their foraging and movement behaviors. Jointly – another project aims at measuring wild pig damage to corn production. These two projects together will quantify the economic losses as well as the spatial patterns of damage associated within and among corn fields, while also providing information regarding more efficient hog control methods.

Another project underway seeks to assess attitudes and perceptions among Mississippi residents in regards to wild hogs and their management using survey statistics and protocols. The fourth project is researching wild hog diet to better estimate damage to a variety of agricultural crops and other natural resources. And lastly, a project that is designed to evaluate - at the national level, all federal, state, and local policy and legislation regarding the wild hog invasion. Additionally, effective and ineffective policy will be evaluated to determine commonalities in social, demographic, economic, and ecological factors that may have contributed to its success or failure. This study will provide state legislators with model legislation that can be successfully passed with the support of stakeholders and the citizenry. It will also provide states without, or with low populations of hogs, a proactive suite of legislation to prevent further spread and facilitate more meaningful eradication of wild hogs.

Estimation of Deer Damage to Soybean Production in Mississippi: A Temporal and Spatial Context:

Mississippi soybean production is currently ranked 14th in the nation with over 76 million bushels produced on 2,695 farms, with a 2010 economic impact of $846 million. Mississippi's deer population is currently estimated to be ≥ 1.75 million animals, with an economic impact to Mississippi in excess of $800 million.Although both soybeans and white-tailed deer are very important to the Mississippi economy, white-tailed deer readily consume soybeans and soybean production has been linked to population dynamics of deer in Mississippi. Thus, in areas where soybean production and deer populations co-occur, there will likely always be conflict regarding deer damage to soybean crops. We propose a study to estimate the impact of white-tailed deer on soybean production in Mississippi. We approach this research with the underlying assumption that in areas where deer populations and soybean production exist, there will be crop depredation to some extent, depending on, ultimately, deer abundance.
