Summary of shrub establishment research conducted on Ducks Unlimited Canada islands in Alberta. A. Fehr and M. Pitt
Material type:
TextPublication details: AB : 1987Online resources: Abstract: Ducks Unlimited Canada builds earth islands in wetlands to provide waterfowl nesting cover. Establishing island vegetation is often unsuccessful because of unfavourable island soil properties. Island vegetation provides nesting cover and stabilizes soil; consequently,island erosion and degradation are minimized, whereas island life and productivity are improved. After studying waterfowl use of Ducks Unlimited (DU) islands, Giroux (1981) recommended that vegetation establishment be treated as a major element of island habitat development. A second DU study concluded that the areal extent of island vegetation is a major factor influencing erosion, and that increasing vegetative cover would decrease erosion (Island Erosion Study Committee 1984).
