Manage ment objectives have since been expanded to provide for a broader spectrum of wildlife, with special emphasis on water fowl, shorebirds and threatened and endangered species; and to provide the visiting public with opportunities for wild life oriented recreation and environmental education to the extent compatible with resource needs. JB 11/84 Aerial view of the refuge looking southward with the Back Bay on the right. The refuge consists of 4,608 acres located in southeastern Virginia. In addition, about 5,600 acres of open bay water within the refuge boundary were Closed to the taking of migratory birds in 1939 by Presidential Proclamation. The refuge extends 4.2 miles along the Atlantic shoreline. About 800 acres of habitat consist of barrier beach and adjacent dunes with an elevation of about 15 feet. The refuge ocean front beach has been described by the Virginia Institute of Marine Sciences as one of the most dynamic of the Virginia Atlantic Ocear^ beaches. The slope of the beach frequently changes radically within one tide cycle. The beach varies in width from 100 to 250 feet at low tide. Marshland, predominately black needlerush, comprises about 3,617 acres or 78% of the refuge. This wetland acreage includes 586 acres in three impoundments. Scattered woodlands, consisting primarily of loblolly pine with some live oak, red maple and sweetgum, comprise 132 acres. The remaining upland area includes 59 acres in grass managed as goose pasture. The Proclamation waters are shallow with an average depth of about three feet. Salinity ranges between four and ten percent sea strength. Bay waters are not influenced by lunar tides but wind is a major factor. Persistent northerly winds may lower the water level as much as one to two feet; while persistent southerly winds have the opposite effect. This wind action also has a pronounced effect on turbidity. The climate of Back Bay is modified continental with mild winters and hot, humid summers. Annual precipitation averages 48 inches. The normal growing season is 251 days. Hurricanes and "northeasters" occasionally affect Back Bay and the surrounding areas, causing damage from wind and high tides. Prior to the regulation of beach vehicular travel, non-wild life oriented visits, primarily associated with the use of off-road vehicles, exceeded 300,000 annually. In recent years, the refuge normally receives slightly over 100,000 visits annually. Public use demand will remain high because of the 325,000 residents of Virginia Beach within forty-five minutes of the refuge and 1.3 million people live within a two hours drive. The presence of mosquitoes, biting flies, greenbriars, poison ivy and cottonmouth moccasins keep visitors and employees humble and the refuge from being completely trampled underfoot or driven over.

HIGHLIGHTS - Construction of the refuge office/visitor contact station began in June 1984 and was near completion by the end of December. - The beach vehicular access situation was monitored seven days/week, twenty-four hour/day from April 4 until July 31. No significant changes resulted but the refuge staff has a better understanding of permittees, time-of-travel patterns and types of permit abuses/violations. - Guards George Batie and Lester Walizer were notified of impending reassignments to Cape Charles National Wildlife Refuge in September. Mr. Batie transferred to Department of Defense at the Norfolk Naval Operations Base on November 11, 1984. Mr. Walizer accepted the reassignment which was effective on November 25, 1984. - Mackay Island National Wildlife Refuge became an independent field station on October 1, 1984 after being a Back Bay satellite since its establishment in 1960. - Fisherman Island National Wildlife Refuge was transferred to the administration of the Cape Charles National Wildlife Refuge effective October 1, 1984.
