Environmental Implications - Snow Geese
This species migrate to the 1002 region of ANWR every year for two to
four weeks before continuing on a 1300 mile journey to Northern Alberta.
Their time spent on the north slope is critical to their survival since
they need to store nutrients for their long migration path. As many
as 500,000 species migrate to the region each year (Hupp et al, 2002).
These birds are herbivores, feeding on cotton grass. A major predator
is the arctic snow fox. The North Slope supports over 60% of the
Pacific population (National Research Council, 2003).
