Final completed project evaluation report for the Interlake Biome of Manitoba / Robert T. Clay.
Material type:
TextPublication details: Winnipeg, MB : 1987.Description: vi, 53 p. : maps ; 28 cmOnline resources: Abstract: In 1984 BSG began a 2 year evaluation of 5 projects in the Interlake region of Manitoba. The objectives were to describe the waterfowl habitat in the vicinity of those marshes and to estimate breeding duck populations and productivity. Habitats remained relatively constant during the 2 year study, despite differences in precipitation. Ample nesting cover was available for both upland and overwater nesters at most projects; however, where spring burning was common, large tracts of potential early upland nesting cover were lost. Emergent vegetation generally had a stunted, sparse appearance and stands tended to be poorly developed. This may be the result of low water fertility which would limit productivity of macrophytes, algae, and ultimately macroinvertebrates. Duck numbers reflected the stability of the habitat,and although numbers changed somewhat between years, the differences were statistically insignificant. Indicated breeding pair densities ranged from 0.53 to 1.65 pairs/flood
