This 190-acre tidal marsh (estuary) on Fir Island, is predominantly vegetated by cattail and sedge and used extensively by waterfowl. Each year, from fall to spring, with February being the prime viewing time, the area is a bird paradise, with snow geese and trumpeter and tundra swans over wintering in huge numbers. (Do note that from October through January is hunting season. (Staying on the dike trails will greatly decrease your exposure.) To enhance the site for both hunting and viewing opportunities, the area is planted annually with cereal grains by local farmers. Originally, the primary focus was pheasant hunting and growing waterfowl forage grains. Management has since shifted to also restoring estuary habitat for Chinook salmon. Part of the perimeter levee has recently been removed to allow tidal and river flows to recreate channels and to provide additional natural estuary habitat. (As seen at the cache location.)
Muck boots are highly recommended for some of the Wildlife area trails. (Fortunately, for you the trail the cache is located on is not one of them!) A Washington Fish and Wildlife permit is required in order to park in the parking lot.
