Summary
Description
This years brood count very likely gives a more thorough inventory of lake production than do the last two years counts: whereas most lakes were spot surveyed from shore in 1983 and 1984, almost all lake shorelines were completely canoed in 1985. On all the lakes inventoried, duck production was significantly higher in 19BS .61 youngacre on 71 lakes than in 1984 .37 youngacre on 9 lakes. However, a direct comparison of the 11 lakes which were surveyed in both years shows that duck production did not increase .44 youngacre in both years, and in view of the more thorough survey method this year, actual production probably decreased. Goose production on lakes also appears to have dropped in 1985; but it should be noted that young geese escape on land more readily than young ducks, so 1984s spot surveys may not have spooked as many goose broods as this years canoe surveys. Both duck and goose production on the Kanuti River were lower this year than last. The survey method was essentially the same in both years. Whitefronted Goose production fell drastically from.05 youngacre in 1984 to.01 youngacre in 1985.
