TextPublication details: Winnipeg, MB : 1982. Ducks Unlimited Canada,Description: xi, 136 p. : ill. , map ; 28 cmOnline resources: Abstract: Investigations to determine effects of wetland development on waterfowl numbers and habitat characteristics were continued by Ducks Unlimited (Canada) in 1981. Five projects were studied. Arnold and Stockton projects are in the third year of pre-construction analysis. White Lake and Skinner's received their second and Nicolle Flats its third year of post-construction evaluation. Analysis of invertebrates, water chemistry, plant ecology and waterfowl populations continued on all projects (only waterfowl counts and habitat mapping were conducted on Skinner's Marsh). Skinner's Marsh and Nicolle Flats experienced large increases in breeding pairs of ducks in 1981 over the pre-construction period. Both marshes are showing a steady annual increase in numbers of breeding ducks since construction, and attract large numbers of waterfowl displaced by drought conditions in surrounding areas. Breeding pairs increased on White Lake because of adequate water levels and good cover conditions produce
