This 5,305-foot steel cantilever truss bridge, designed by master bridge engineer Conde B. McCullough, was the longest structure on Oregon’s highway system when constructed in 1936. It spans the entrance to Coos Bay, carrying U.S. Hwy. 101.
Scotch broom is a pioneer species known to displace native plant species and increase the costs of timber production. It readily invades disturbed sites, natural areas, dunes and public and private forest lands. Maintenance of rights-of-way, facilities, parkland and private property costs millions of dollars each year because of rapid growth of young plants and the plant's persistent nature. Seeds of Scotch broom are long-lived (50 years plus) and mature plants are prolific seed producers, establishing persistent seed banks requiring long-term management objectives. The largest costs attributed to scotch broom come from additional inputs needed to establish trees in commercial and public timberlands. It is estimated that Scotch broom costs Oregon $47 million dollars annually in lost timber production.
Buffleheads have evolved their small size in order to fit the nesting cavity of their "metabiotic" host, a woodpecker, the Northern Flicker. Due to their small size, they are highly active, undertaking dives almost continuously sustained by their high metabolism. They do not tend to collect in large flocks; groups are usually limited to small numbers. One duck will serve as a sentry, watching for predators as the others in the group dive in search of food. Buffleheads are amongst the last waterfowl to leave their breeding grounds and one of the world's most punctual migrants, arriving on their wintering grounds within a narrow margin of time.
The Reserve was designated in 1974 as the first unit of the National Estuarine Research Reserve System , a network of estuarine habitats protected and managed for the purposes of long-term research, education, and coastal stewardship. Established by Congress in 1972 as part of the Coastal Zone Management Act and is administered as a partnership between the National Oceanic and Atmospheric Administration (NOAA) and the coastal states.
