An Extraordinary Patch Of Feral Hog Damage In Florida Before And After Initiating Hog Removal, Richard M. Engeman, John Woolard, Henry T. Smith, Jean Bourassa, Bernice U. Constantin, Daniel Griffin

Human–Wildlife Interactions

Feral hogs (Sus scrofa) are a particularly destructive exotic species in the United States (U.S. Department of Agriculture 1999), including Florida, which, along with Hawaii, is one of 2 states cited as having the most severe invasive species problems (U.S. Congress 1993) in the country. First introduced to North America by the European colonists (Conover 2007) hogs were one of the first invasive exotic species to take hold in Florida. They can transmit disease to livestock (Hartin et al. 2007) and humans (Conover and Vail 2007). They impose a variety of negative environmental impacts, including habitat degradation and …


Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearly, R. Neal Wilkins Jan 2007

Appreciating Feral Hogs: Extension Education For Diverse Stakeholders In Texas, Dale Rollins, Billy J. Higginbotham, Kenneth A. Cearly, R. Neal Wilkins

Human–Wildlife Interactions

Texas harbors the largest population of feral hogs (Sus scrofa) in the United States, with populations estimated at >2 million. Depending on one’s perspective, feral hogs are either a pariah (from the farmer’s standpoint) or a popular sporting animal (from a hunter’s standpoint). As feral hogs increase in range and density, conflicts among stakeholders are sure to increase. Texas Cooperative Extension (TCE) initiated educational programs in 1991 to address concerns regarding the presence and management of feral hogs. Since that time, we have developed various workshops, symposia, and educational materials (e.g., print, videotape, and website) as means of …


Adaptive And Economic Management Methods For Feral Hog Control In Florida, Richard M. Engeman, Bernice U. Constantin, Stephanie A. Schwiff, Henry T. Smith, John Woolard, John Allen, John Dunlap Jan 2007

Adaptive And Economic Management Methods For Feral Hog Control In Florida, Richard M. Engeman, Bernice U. Constantin, Stephanie A. Schwiff, Henry T. Smith, John Woolard, John Allen, John Dunlap

Human–Wildlife Interactions

Feral hogs (Sus scrofa) negatively impact the environment in most places around the world where they have been introduced into the wild. In many places, hog removal is essential to protect special habitats, in particular, wetlands. This paper describes techniques developed for use in adaptive management approaches to enhance hog removal efforts in Florida, as well as methods to evaluate the economic impacts from hog management. A valuable adaptive management tool that can be an easily applied index to monitor feral hog activity is track plots. This method has been effective for monitoring hog distribution and relative abundance, …


Crop Diversifi Cation Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt Jan 2007

Crop Diversifi Cation Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt

Human–Wildlife Interactions

Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most v …
