Feral Hogs: A Texas Perspective

Feral hog (Sus scrofa) populations are a growing concern, and evidence of their presence has spread throughout the state. With the exception of a few areas in the northern panhandle and far western Texas, this invasive species successfully exists in almost every county; and evidence of their exponential population growth and the damage they cause is no longer confined to rural areas. Feral hogs affect farmers, livestock producers, private and public industry, and individuals living in suburban and urban areas. Wildlife, agriculture, property owners, animal and public health interests are all experiencing feral hog issues at different levels. Surveys indicate that the presence of feral hogs impact Texans in a variety of ways including: damage to croplands, predation of livestock, destruction of natural resources and urban landscaping and the threat of disease transmission to domestic livestock and people. The perspective most often heard in Texas is one of disdain for the feral hog. However, there are some that enjoy the sporting and economic opportunities that feral hogs provide. The consensus however is, that there is much to learn about this adaptable species. Continued research is needed to understand the biology and behavior of feral hogs to better manage this species and how their presence impacts all parties involved. The perspective of the feral hog in Texas is one of differing viewpoints and priorities. This paper will seek to explore some of the issues surrounding this invasive species

A Critical Look at Wild Pig Elimination: Myths and Facts

Wild pigs (Sus scrofa) are abundant and widely distributed in the United States. They damage crops and pastures, predate livestock and sensitive species, impact ecosystem functions, and damage personal property. To address these issues, some states in the United States are seeking complete elimination. A frequently asked question by stakeholders is: “What portion of the population needs to be removed annually to reach elimination?” The number 70% is widely touted as the answer. There is little scientific evidence to support that this percent annual removal would be needed to achieve elimination, yet 70% has now become a standard measure of management success, and in some cases the rationale for support or lack thereof for operational management programs. For example, some stakeholders believe that if a wild pig elimination program does not remove 70% of the population annually across the state, then it is not being effective. These strong and widespread anecdotal beliefs may actually impede management progress. Herein, we describe the likely origin of the 70% parameter and the science to support why this metric measuring success of an elimination program is inaccurate
