conditions in Stratum C was reflected in the 18 percent increase of waterfowl 
populations there. Pintails, mallards, gadwall, baldpate and redheads showed 
the greatest gain in this area. In the parklands the most apparent increase 
occurred among the pintails and scaup. The pintail population rose particularly 
in areas where they were sparsely found before. This is especially true along 
the extreme northern edge of the parklands.
