Development of an Aerial Breeding Pair Survey of Dusky Canada Geese (Branta canadensis occidentalis) on the Copper River Delta, Alaska

Metadata Updated: May 11, 2018

The dusky Canada goose (Branta canadensis occidentalis) population has declined for several years (Cornely and Jarvis 1984 Cornely et al. 1985; Campbell 1984, 1988; King and Derksen 1986; Conant 1990). The decline has been attributed to many factors including hunting (Jarvis and Cornely 1988), but most notably the detrimental effects of vegetation succession on the Copper River Delta (Delta) following the Good Friday earthquake of 1964 (Bromley 1976, Pacific Flyway Management Plan 1984) which lifted the Delta as much as two meters (Potyondy et. al 1975). Concurrent with the invasion of woody plants there has been an influx of mammalian predators, primarily brown bears (Ursus arctos) and coyotes (Canis latrans), which have had a significant impact on nest success (Campbell 1988, 1990). Habitat used by geese for nesting has changed (Timm and Havens 1974, Campbell 1988, 1990) and it is assumed that those changes are influencing annual production (Campbell 1984, 1988, 1990, Campbell and Rothe 1986).
