Ankeny
Natural Wildlife Refuge

The
Willamette Valley was once a rich mix of wildlife habitats. Valley
wetlands were once extensive, with meandering stream channels and vast
seasonal marshes. Today, the valley is a mix of farmland and growing
cities, with fewer areas remaining for wildlife.
Ankeny NWR was created to provide a vital wintering habitat for
over 100,000 Dusky Canada geese. Unlike other Canada geese, Duskies have
limited summer and winter ranges. They nest on Alaska's Copper River Delta
and
winter almost exclusively in the Willamette Valley. Habitat loss,
predation, and hunting have caused a decrease in population. Ankeny NWR
contains about 2,800 acres of flat to gently rolling land near the
confluence of the Willamette and Santiam rivers. The refuge's fertile
farmed fields, hedgerows, forests, and wetlands provide a variety of
wildlife habitats.
Ducks, geese, and swans are commonly seen in refuge fields and
ponds through the fall and winter. Ankeny residents, like the northern
saw-whet owl, attract area bird watchers. The refuge is open to
limited opportunities for wildlife-oriented education and recreation.
The Willamette Valley refuges incorporate an intensive
cooperative farming program in order to provide high protein browse
(annual ryegrass, perennial ryegrass and fescue) for seven subspecies of
wintering Canada geese, with primary emphasis on the Dusky subspecies.
Under cooperative agreements, area farmers plant refuge fields. Some
fields are planted annually and others are mowed or burned to produce the
tender, nutritious grasses preferred by geese.
The geese also need water for resting and foraging habitat. Many
refuge wetlands occur naturally; others are created by dikes and levees.
In some low-lying areas of the refuge, wetlands that were drained or
channelized by previous owners have been restored to increase diversity
and desirability of habitat for wildlife. The majority of wetlands are
being managed as moist soil units, to promote growth of wetland food
plants (millet, smartweed, sedges, etc.) used as food by waterfowl and
other wildlife.
By resting in undisturbed areas on the refuges, wintering geese
regain energy reserves required for migration and nesting. This sanctuary
also reduces depredation problems on neighboring private lands by
encouraging waterfowl to use refuge resources. Because of their need for a
quiet resting area, waterfowl habitat is closed to public entry while the
geese are in residence in order to minimize human disturbance. Recently,
the refuge has increased efforts to restore and expand riparian forest and
wet prairie habitats.
