Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland–urban interface, a more recent and especially challenging issue

Though the forests are still green and the lakes full of water, an unending stream of invasions is changing many ecosystems around the world from productive, tightly integrated webs of native species to loose assemblages of stressed native species and aggressive invaders. The earth is becoming what author David Quammen has called a "planet of weeds." Nature Out of Place brings this devastating but overlooked crisis to the forefront of public consciousness by offering a fascinating exploration of its causes and consequences, along with a thoughtful and practical consideration of what can be done about it. The father and son team of Jason and Roy Van Driesche offer a unique combination of narratives that highlight specific locations and problems along with comprehensive explanations of the underlying scientific and policy issues.Chapters examine Hawaii, where introduced feral pigs are destroying the islands' native forests; zebra mussel invasion in the rivers of Ohio; the decades-long effort to eradicate an invasive weed on the Great Plains; and a story about the restoration of both ecological and human history in an urban natural area. In-depth background chapters explain topics ranging from how ecosystems become diverse, to the characteristics of effective invaders, to procedures and policies that can help prevent future invasions. The book ends with a number of specific suggestions for ways that individuals can help reduce the impacts of invasive species, and offers resources for further information.By bringing the problem of invasive species to life for readers at all levels, Nature Out of Place will play an essential role in the vital effort to raise public awareness of this ongoing ecological crisis.

A feral pig population on Santa Catalina Island, California, was studied for 17 months beginning in July 1980. Density was estimated to be 21 to 34 pigs/km2 (95% confidence interval) using capture-recapture techniques. Dry season home ranges determined from radio-telemetry data were small and differed significantly between boars and sows. Patterns of habitat use according to vegetative community, topographic position, slope, aspect, elevation, vertical distance to water, and horizontal distance to water were examined. During the dry season, pigs preferred cool moist canyon bottoms, the result of both a physiological need for free water and behavioral responses to high environmental temperatures. Patterns of utilization during the wet season appeared to be primarily a function of food availability. Diets were primarily herbaceous, although small amounts of insects and vertebrate matter were eaten, and varied seasonally. Fruits and forbs were the most preferred foods in the dry season, while fruits, grasses and forbs were most preferred during the wet season. Seasonal differences in diets reflected changes in availability and phenology of plants. Seasonal trends were apparent in acid detergent fiber, cellulose, and crude protein levels in the diet, but not in acid detergent fiber, phosphorus, gross energy, digestible energy, protein digestibility and cellulose digestibility. Diets were characterized as high in fiber, low in energy and seasonally deficient in protein. Kidney fat and femur marrow fat indices indicated pigs declined in body condition in summer and fall, and improved in winter and spring. Optimal performance of pigs on Catalina appeared to be linked to the quantity of the acorn crop in early fall and the timing and duration of fall-winter rains. A seasonal pattern in breeding was evident, with conception apparently linked to both nutrition and photoperiod. Fertility declined in late spring and summer as photoperiod increased; onset of estrus and breeding in fall or winter were regulated by nutritional status of sows. Litter size as measured by fetal counts was 5.00 ± 0.36 S.E., and sows averaged 0.86 ± 0.17 S.E. litters over a 12 month period. Most sows were older than 1 year when they first conceived, and litter size increased from puberty and peaked at 2-3 years of age. Intrauterine mortality of fetuses averaged 25% and piglet mortality was estimated to be 58% prior to weaning. Mortality rates appeared to be higher for piglets born in summer than in winter or spring.
