Environmental Impact Research Program. Beaver Pond Management. Section 5.5.2, US Army Corps of Engineers Wildlife Resources Management Manual

摘要

A management techniques report on beaver pond management is provided as Section 5.5.2 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 developing and implementing techniques for waterfowl management on project lands. Topics covered for beaver ponds include site selection, draining the pond, planting, redflooding, personnel and costs, and cautions and limitations. Ponds created by beavers (Castor canadensis) satisfy many needs for waterfowl as roosting, resting, nesting, and foraging habitat. Thus, these ponds provide opportunities for waterfowl management. A technique consisting of draining a pond and planting Japanese millet (Echinochloa crusgalli) is described in this report; the procedure has been widely used in the South and should be feasible throughout the range of Japanese millet. Recommendations are provided for evaluating potential management sites, constructing and installing drainage structures, planting, and reflooding. (Author)
