Waterfowl responses to seasonally flooded fields on Alaksen National Wildlife Area, 1980-1991 / John P. Hatfield and G.E. John Smith. : CW69-5/232E-PDF
"Responses to two seasonally flooded fields on Alaksen National Wildlife Area by waterfowl from1980 to 1991 are presented. Seven waterfowl species are the main beneficiaries of management operations: Mallard (Anas platyrthyncos), American Wigeon (A. americana), Northern Pintail (A. acuta),Green-winged Teal (A. Creeca), Gadwall (A. Strepera), Northern Shoveler (A. clypeata) and Canada Goose (Branta canadensis). Total duck-days increased significantly when fields were managed "flooded" as opposed to "dry". The net effect of flooding regimes on numbers of waterfowl present were studied for each field after adjusting for influences due to the month of the year, and the year itself. The significance of some management techniques are discussed"--Abstract.
