Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott
Wild Horse Demography: Implications For Sustainable Management Within Economic Constraints, Robert A. Garrott
Human–Wildlife Interactions
Management of wild horse (Equus ferus caballus ) populations on western U.S. rangelands has been a challenge since horses were given legal protection through the passage of the Wild Free-Roaming Horses and Burros Act (WFRHBA) in 1971. Horses have no eff ective predators, and unmanaged populations can double in 4–5 years and triple in 6–8 years. In order to meet the multiple-use paradigm for managing public rangelands, the Bureau of Land Management (BLM) has limited horse population growth through the periodic capture and removal of animals. While the WFRHBA mandates disposal of captured horses through placement into private ownership and …

Consequences Of Porcine Zona Pellucida Immunocontraception To Feral Horses, Cassandra M.V. Nuñez
Human–Wildlife Interactions
Porcine zona pellucida (PZP) immunocontraception was developed to provide a more humane, effective, and inexpensive method of population regulation for wildlife species. It has been used to regulate populations of several species including white tailed deer (Odocoileus virginianus), elk (Cervus elaphus ), black bear (Ursus americanus ), and the feral horse (Equus ferus caballus) with varying levels of success. Early studies on Assateague Island National Seashore, Maryland, USA, suggested PZP was as an ideal form of fertility control because it reduced the likelihood of conception to
