註釋

"Recently, in both the scientific and the popular press, wildlife managers and administrators have proclaimed that there are too many Lesser Snow Geese Anser caerulescens caerulescens (hereafter referred to as Snow Geese) in North America. The experts have recommended that goose numbers be reduced in order to prevent the geese from destroying Arctic coastal habitats on which they and other wildlife depend as feeding grounds. It is important to realize that this reduction program is aimed at the Midcontinent Snow Goose Population, which nests in the Eastern and Central Canadian Arctic. So far, that program does not apply to the much smaller and more western populations of Snow Geese, which nest in the Western Canadian Arctic and on Wrangel Island, Russia. Those populations, which are the subject of this report, have shown quite different histories and have presented different management problems"--Background.
