Franz Lake National Wildlife Refuge is located in southwest Washington State, within the Columbia River Gorge National Scenic Area. The refuge provides a variety of habitats including riparian wetlands, Columbia River riparian corridor blocks, transitional woodlands from lower elevation willows, and cottonwoods to mid-elevation old-growth fir and cedar with associated native understory shrubs, open meadows, and numerous streams and seeps. [4]
A wetland is a distinct ecosystem that is inundated by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of functions, including water purification, water storage, processing of carbon and other nutrients, stabilization of shorelines, and support of plants and animals. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. Whether any individual wetland performs these functions, and the degree to which it performs them, depends on characteristics of that wetland and the lands and waters near it. Methods for rapidly assessing these functions, wetland ecological health, and general wetland condition have been developed in many regions and have contributed to wetland conservation partly by raising public awareness of the functions and the ecosystem services some wetlands provide.
The Columbia River is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the US state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is 1,243 miles (2,000 km) long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific.
A woodland or wood is a low-density forest forming open habitats with plenty of sunlight and limited shade. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are referred to as forests.
Franz and Arthur lakes contain healthy stands of wapato (Sagittaria latifolia), which provide an important wintering habitat for tundra swans and other waterfowl. As many as 1,000 wintering tundra swans have been observed on Franz Lake. Other common waterfowl include western Canada geese, mallards, northern pintails, gadwalls, green-winged teal, northern shovelers, canvasbacks, ring-necked ducks, and American wigeon. The refuge also provides abundant habitat for wading birds such as great blue herons and rails, as well as songbirds that use grass/sedge meadows, cattail ponds, willow thickets, and riparian forests. Other wildlife commonly observed on the refuge include gulls, band-tailed pigeons, red-tailed hawks, crows, killdeer, western painted turtles, Pacific tree frogs, western toads, garter snakes, and California ground squirrels. [4]
Sagittaria latifolia is a plant found in shallow wetlands and is sometimes known as broadleaf arrowhead, duck-potato, Indian potato, or wapato. This plant produces edible tubers that were extensively used by the Indigenous peoples of the Americas.
The tundra swan is a small Holarctic swan. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan of the Palaearctic and the whistling swan proper of the Nearctic. Birds from eastern Russia are sometimes separated as the subspecies C. c. jankowskii, but this is not widely accepted as distinct, with most authors including them in C. c. bewickii. Tundra swans are sometimes separated in the subgenus Olor together with the other Arctic swan species.
The Canada goose is a large wild goose species with a black head and neck, white cheeks, white under its chin, and a brown body. Native to arctic and temperate regions of North America, its migration occasionally reaches northern Europe. It has been introduced to the United Kingdom, New Zealand, Argentina, Chile, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; it tends to be found on or close to fresh water.
Several springs and seeps on the refuge have been identified as critical brood areas for Coho salmon and other juvenile salmonids. The refuge may be viewed from an overlook located off-refuge along State Highway 14. Arranged group tours are also available. [4]
The coho salmon is a species of anadromous fish in the salmon family, one of the several species of Pacific salmon. Coho salmon are also known as silver salmon or "silvers". The scientific species name is based on the Russian common name kizhuch (кижуч).
State Route 14 (SR 14) is a 180.66-mile-long (290.74 km) state highway in the U.S. state of Washington. The highway travels east-west on the north side of the Columbia River, opposite Interstate 84 (I-84) to the south in Oregon. SR 14 forms a section of the Lewis and Clark Trail Scenic Byway and begins at an interchange with I-5 in Vancouver. The highway travels east as a four-lane freeway through Camas and Washougal and intersects I-205. SR 14 continues east as a two-lane highway through Clark, Skamania, Klickitat, and Benton counties before it ends at an interchange with I-82 and U.S. Route 395 (US 395) near Plymouth.
