Habitat conditions, grizzly bear predation of nests, and spring use of the Anderson River delta by Lesser Snow Geese and Brant, 2005-2006 / [by] Joachim Obst, James E. Hines, Jean-François Dufour, Paul F. Woodard and Robert G. Bromley. Ottawa - Ontario : Environment Canada. c2013. x, 59p. : coloured maps, references, tables ; 28 cm. Technical report series 0831-6481 523 Numbers of Lesser Snow Goose and Black Brant nesting at the Anderson River Delta Migratory Bird Sanctuary (ARDMBS), Northwest Territories, have declined substantially over the past decade or longer. Hypothesized causes of the declines include loss of nesting habitat, nest predation by grizzly bears or other predators, and human disturbance. The present investigation was carried out in the spring of 2005 and 2006 to examine possible causes of the population decline, evaluate current use of the sanctuary by geese, and describe current habitat conditions within a 44 km2 study area at ARDMBS.
