form the pond through the tidegate at extreme low tides . With <br /> little to no input the remaining water becomes stagnate and <br /> algae laden. <br /> Wildlife : <br /> Winter : <br /> Wildlife use is highest in the winter because of the <br /> proximity to Union Slough and the Everett Sewage Lagoons . The <br /> lagoons and sloughs as well as the tidal flats attract a large <br /> population of migrating and wintering waterfowl . Of these many <br /> are widgeon and Canada geese . Along with the resident mallard <br /> populations and mallard migrants there is a large population of <br /> grazing birds in the area . Early morning feeding forays by a <br /> large number of birds is common. They are drawn to the green <br /> grass which is young and succulent. The birds move about the <br /> valley and feed on any pasture that is grazed or hayed that <br /> produces the same values as the Biringer site. Waterfowl use <br /> the runoff pond in the spring, fall and winter when water <br /> quality is good but have not been reported to be nesting or <br /> summering on the site. The blackberry bramble on the dikes is <br /> used by small birds for nesting, cover and feeding. During my <br /> surveys the only species identified were song sparrow and <br /> robin. Small mammal use is limited to a variety of mice, skunks <br /> and raccoons . Coyote tracks and sign were found along the <br /> periphery of the fields and on the slough dike. <br /> Overall the area receives low use and appears to be a <br /> part of the greater pasture type complex that supports <br /> waterfowl during the fall and spring migrations and is used <br />
