Dense nesting cover establishment techniques / D.B. Wark.
Material type: TextPublication details: 1987. MB : Ducks Unlimited Canada,Description: iv, 26 p. ; 28 cmOnline resources: Abstract: Numerous studies have indicated that tall rank nesting cover is more productive of waterfowl than sparse light cover or intensively farmed uplands (Duebbert and Kantrud 1974, Duebbert and Lokemoen 1976, Higgins 1977, Kirsch et al 1978). In many instances land secured by wildlife agencies is converted to dense nesting cover (D.N.C.) to maximize waterfowl production. Traditionally D.U. has planted a mixture of cool season introduced grasses and legumes on nesting islands and D.N.C.plots. Recently it has become apparent that maintenance of productive,weed free stands of this mixture over an extended period of time (8-10 years) is costly and time consuming. To overcome similar problems wildlife agencies in the United States have increasingly shifted their emphasis to establishing stands of cool and warm season native grasses as wildlife cover. Waterfowl and other ground nesting birds have been found to nest readily in this type of cover (Klett et al. 1984, George et al. 1979, Kruse persItem type | Current library | Collection | Call number | Status | Date due | Barcode |
