Environmental Impact Research Program. Impassable Wire Fences: Section 5.2.3, US Army Corps of Engineers Wildlife Resources Management Manual

摘要

A management techniques report on impassable wire fences is provided as Section 5.2.3 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report was prepared as a guide to assist Corps biologists and resource managers in the selection and implementation of impassable wire fence techniques where these fences are required or desirable for wildlife and habitat management programs. Topics covered include description, design and construction, placement, personnel and costs, maintenance, and cautions and limitations. Impassable wire fences are barriers that restrict wildlife access into areas that are hazardous or where grazing is not desired. They may be required along concrete-lined canals to prevent drowning or maiming of wildlife, and are often needed along highways to prevent large mammals from becoming a hazard to motorists. Impassable fences may also prevent destruction of newly planted habitats, nesting areas, and riparian vegetation. Two basic types of impassable fences, upright fences and slanting fences, are described in this report. Details are provided on their design, construction, installation, maintenance, and placement in suitable terrain. Specification drawings and lists of materials required for construction are included.
