Beschreibung:
The addition of loafing rafts to five parkland and six grassland lakes in Alberta, as a means of increasing breeding ducks, was evaluated between 1960 and 1964 by comparing breeding pair densities before and after treatment on similar numbers of experimental and control lakes. Lakes ranged in area from 12-84 acres and had little or no emergent aquatic plant cover. Rafts, approximately 1½ × 9 ft, were anchored 20 yards from shore at the rate of one raft/100 yards of shoreline. There was no significant (P > 0.05) evidence that the addition of rafts affected duck use.
