Methods And Strategies For Managing Feral Hog Damage In Grain Production Areas In Central Texas, T. J. Muir, Gary Mcewen
Methods And Strategies For Managing Feral Hog Damage In Grain Production Areas In Central Texas, T. J. Muir, Gary Mcewen
Managing Vertebrate Invasive Species
Texas Wildlife Services (WS) personnel conduct feral hog damage management projects to protect a variety of resources in Texas. For the past 12 years, WS personnel have conducted feral hog (Sus scrofa) damage management projects on an 11,000 acre wildlife management area (WMA) and surrounding farmlands located in central Texas. The WMA is managed by the United States (US) Army Corp of Engineers and Texas Parks and Wildlife Department. Surrounding areas are farmlands and the primary crops grown there are corn and grain sorghum. Feral hogs have damaged area grain crops and the US Army Corp of Engineers …
Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica W. Fantinato
Management Of Rodent Populations At Airports, Gary W. Witmer, Jessica W. Fantinato
USDA Wildlife Services: Staff Publications
Birds pose serious hazards at U.S. airports because of the potential for collisions with aircraft. Raptors, in particular, are hazardous to aircraft safety due to their size, hunting behavior, and hovering/soaring habits. Reduction of rodent populations at an airport may decrease raptor populations in the area and therefore, reduce the risk that raptors pose to aircraft. Rodent populations can be reduced by population management (i.e., use of rodenticides) or by habitat management (i.e., vegetation management, barriers, and land uses) that reduces the area’s carrying capacity for rodents. We discuss potential approaches to reduce rodent populations at airports within the context …
Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Comprehensive Management Of Commensal Bats, Stephen C. Frantz, Brian R. Laniewicz
Wildlife Damage Management Conference Proceedings
This paper reviews the basic concepts behind a comprehensive management approach to managing commensal species, and then considers how this approach is applied to bats that live within and about the built environment. Management activities should take into consideration the whole environment in which the target species is active, including the periodic changes that occur within that environment. Comprehensive management includes a clear understanding of: the biology, behavior and ecology of the species to be managed; the environment in which that species is active (especially harborage location); and the appropriate intervention methods used to manage such species. Interventions fall under …
Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser
Investigations Of Methods To Reduce Damage By Voles, Gary W. Witmer, A. A. Hakim, Brian W. Moser
Wildlife Damage Management Conference Proceedings
Voles (Microtus spp.), small burrowing rodents, range over much of North America. Populations cycle and achieve peak densities every 3-5 years. This can result in severe damage to various resources: orchards, forest plantings, alfalfa and other crops, ornamentals, lawns, and gardens. A variety of methods are used to reduce vole damage, but there is still a need for new, cost-effective, and environmentally benign approaches. We investigated numerous candidate repellents and barriers with indoor vole colonies in soil-filled tanks. Several compounds (blood meal, capsaicin, castor oil, coyote urine, quebracho, and thiram) showed promise as repellents, but only at high concentrations. Many …
Integrated Management Tactics For Predicting And Alleviating Pocket Gopher (Thomomys Spp.) Damage To Conifer Reforestation Plantings, Richard M. Engeman, Gary W. Witmer
Integrated Management Tactics For Predicting And Alleviating Pocket Gopher (Thomomys Spp.) Damage To Conifer Reforestation Plantings, Richard M. Engeman, Gary W. Witmer
USDA Wildlife Services: Staff Publications
Pocket gophers cause extensive damage to reforestation plantings in the western United States, and pose acute and chronic problems for forest managers. We examine the components of an integrated pest management strategy for reducing pocket gopher damage to conifers: the predictive factors for assessing the risk for damage, techniques for monitoring gopher populations and assessing efficacy of control methods, and damage control strategies and methods. The information in each component is reviewed and presented so that an optimal damage reduction plan can be developed in a logical, cost-effective, environmentally responsible fashion.
