As a result of substantial ecological and economic damage attributed to wild pigs (Sus scrofa), there is international interest in using pharmaceutical baits to control populations. To assess the efficacy and specificity of baiting programs, chemical biomarkers can be used to evaluate uptake of pharmaceutical baits. Rhodamine B (RB) is known to be an effective biomarker in wild pigs. However, significant data gaps exist regarding the minimum effective dosage and persistence of RB in wild pigs. We used a controlled doubleblind study experiment conducted in spring of 2014 on the Savannah River Site, Aiken, South Carolina, USA, wherein …

Context. Wild pigs are an invasive species linked to numerous negative impacts on natural and anthropogenic ecosystems in many regions of the world. Robust estimates of juvenile wild pig survival are needed to improve population dynamics models to facilitate management of this economically and ecologically important invasive species. Despite this critical knowledge gap, to date no successful known-fate study of wild piglet survival (age) has been conducted, due to a lack of appropriate method for this species. Aims. To aid in locating and tagging neonates, we piloted the use of vaginal implant transmitters (VITs) in adult wild pigs and evaluated …
No Filters, No Fridges: A Method For Preservation Of Water Samples For Edna Analysis, Kelly E. Williams, Kathryn P. Huyvaert, Antoinette J. Piaggio

Background: Advancements in the detection of environmental DNA (eDNA) for detecting species of interest will likely allow for expanded use of these techniques in the field. One obstacle that continues to hinder applications in the field is the requirement of a cold chain of storage for water samples containing eDNA. While eDNA has been successfully preserved using Longmire’s lysis buffer applied to filters, it has yet to be tried with freshwater samples collected for eDNA detection of an invasive species. We tested the utility of Longmire’s solution (100 mM Tris, 100 mM EDTA, 10 mM NaCl, 0.5 % SDS, 0.2 …

Feral pig populations continue to increase and disperse into unoccupied habitats in North America. Associated damages and control efforts cost U.S. taxpayers as much as $1.5 million/year. Toxicants show promise for feral pig control programs and may be more cost-effective than contemporary methods (i.e., trapping, aerial gunning, and dog-hunting). However, no toxicants are registered for feral pig control in the U.S. Development of sodium nitrite as an active ingredient in pig toxicants is ongoing in Australia, and a registration has been granted in New Zealand. Sodium nitrite is a strong oxidizer and is unpalatable to feral pigs, and thus it …
Too Many Hogs? A Review Of Methods To Mitigate Impact By Wild Boar And Feral Hogs, Giovanna Massei, Sugoto Roy, Richard Bunting
Too Many Hogs? A Review Of Methods To Mitigate Impact By Wild Boar And Feral Hogs, Giovanna Massei, Sugoto Roy, Richard Bunting
Human–Wildlife Interactions
Feral hogs (Sus scrofa) are among the most widely-distributed mammals in the world and have the highest reproductive output compared with other ungulates. Worldwide, feral hogs are increasing in range and numbers. Human–feral hog conflicts include impact on abundance and richness of plant and animal species, crop damage, predation on livestock, vehicle collisions, and disease transmission. We reviewed methods employed to mitigate the impact of feral hogs on human activities and discussed these methods in terms of effectiveness, feasibility, costs, and social acceptance. Traditional methods of control include trapping, angering, shooting, poisoning, and Judas hogs. Nonlethal methods of …

Wild pigs are and will continue to be a challenging problem for wildlife managers, landowners, farmers, conservationists, and others. Despite ongoing control programs, wild pigs have increased both their range and population size. Because of this growth, wildlife managers will increasingly be involved in dealing with problems caused by wild pigs traditionally, as well as emerging problems such as landscaping damage in suburban areas. Successful management strategies will depend upon persistent, adaptive, and integrated management programs that incorporate sound biological and ecological information. An integrated management approach, in addition to addressing the biological and ecological aspects of wild pigs, will …
