This study addresses the population dynamics, factors influencing goose habitat and population productivity, as well as the maintenance of optimal levels of Canada geese in Jackson Hole, Wyoming durng the period 1965-1989. Mean breeding pairs increased 54% from 17 pairs in 1965-76 to 180 pairs 1977-1989. Mean clutch size in 1979-80 was 5.0 compared to 5.2 for 1962-64 with mean brood sizes being 4.0 and 4.7, respectively. Thus maximum capacity for canada goose production. Analysis of band recoveries indicated that the adjusted average annual mortality rate for geese banded in 1961-1972 decreased by slightly more than 8% in comparison to those banded in 1956-60. Also, 1961-172 survival rates were higher in the 3rd year following bandng and continued to be higher well beyond the 6th or 7th year than the survival rates of the 1956-1960 birds.
