Feral Horses, Feral Asses, And Professional Politicians: Broodings From A Beleaguered Biologist, Vernon C. Bleich
Feral Horses, Feral Asses, And Professional Politicians: Broodings From A Beleaguered Biologist, Vernon C. Bleich
Human–Wildlife Interactions
As a member of National Wild Horse and Burro Advisory Board, I gained insight into several aspects of feral equid management that previously had been somewhat cryptic. Foremost in my experience, though, was the dedication and professionalism of the board members with whom I served. During my tenure, the professional approach to management and the frustration faced by employees within the Horse and Burro Program became increasingly apparent. Further came the realization that the effectiveness of the board and program can be improved substantially, if (1) the board is provided the opportunity to rebut or counter incorrect or misleading information …

Raven Control From A Conservation Biology Perspective, David J. Delehanty
Human–Wildlife Interactions
The common raven (Corvus corax; raven) is a large, highly intelligent passerine songbird with a Holarctic distribution attributable to a high degree of plasticity in its foraging and nesting behavior. Historically, ravens have received special attention in human culture, being either respected or vilified. In the western United States, ravens are exploiting the expanding human enterprise, which provides them with unintended subsidies of food, water, and breeding locations, allowing ravens to expand their range and increase in population density and resulting in raven depredation threatening species of conservation concern. From a conservation biology perspective, increased raven populations present …
A Review Of Contemporary U.S. Wild Horse And Burro Management Policies Relative To Desired Management Outcomes, Keith A. Norris
A Review Of Contemporary U.S. Wild Horse And Burro Management Policies Relative To Desired Management Outcomes, Keith A. Norris
Human–Wildlife Interactions
Legally defined “wild” horse (Equus ferus caballus ) and burro (E. asinus ; WHB) populations in the United States exceed established population objectives. The context of WHB policy and management can be categorized into ecological, geographical, legal, social, and political perspectives. Ecologically, all WHB populations in the United States are considered feral animals, but certain populations are afforded protection and management by the federal Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971. The current policy and management paradigms under which the WFRHBA is being implemented has contributed to rangeland degradation, poor WHB health, and impacts to native wildlife. This …

Human–Wildlife Interactions
The Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971 established all “unbranded or unclaimed” equids on U.S. public lands as “living symbols of the historic and pioneer spirit of the West.” Today, >72,000 feral horses (Equus ferus caballus) and burros (E . asinus ; WHB) live on western U.S. public rangelands. The number of WHBs exceeds the Bureau of Land Management’s maximum Appropriate Management Level (AML) of 26,715 by a factor of approximately 2.7 and has nearly doubled from 2007–2015. The AML was set to balance WHB numbers with rangeland health and support other uses such as wildlife habitat …
