While population reductions methods, such as capture and removal <br />and increased hunting kill, have been used, none have be adequately <br />tested or documented in the literature. This project will test further <br />removal and translocation. <br />Objectives: <br />1. To assist with development of population objectives, i. e., the <br />acceptable number of geese at specific sites within the city. <br />2. To model populations and estimate removal levels needed to <br />attain and maintain desired population levels. <br />3. Provide technical expertise and participate in public hearings and <br />assist with public relations. <br />4. To coordinate and do goose removal in 1997, 1998, 1999, and <br />2000 as population control procedures. <br />5. To monitor population levels from 1997 to 2000 to ascertain <br />population reduction effectiveness. <br />Methods: <br />Model- -Much of the data necessary to construct a model have been <br />gathered from 1973 to 1987 for the Metropolitan Twin Cities Canada <br />Goose populations (Sayler 1977, Cooper unpubl. data). Parameters <br />that have been measured include participation in breeding by sex <br />and age class, age related productivity, effect of re- pairing, <br />emigration and immigration, gosling, subadult, and adult survival. <br />Additional data are needed on the effect of density reduction o n <br />breeding participation, dispersal, and survival. These data are being <br />obtained by capturing and neckbanding (Sherwood 1966) flightless, <br />immature geese, and subsequently capturing and removing the <br />breeding segment of the population the next summer. Because <br />Canada geese do not breed until 2 years of age, or older, b y <br />monitoring the breeding participation rate of the marked geese in <br />the following 2 years and comparing the rate of participation with <br />Page 20 <br />
