Topography
Tidal salt marsh is some of the most valuable wildlife habitat in Delaware; thus large portions of the refuge have been maintained in a near pristine state. The marsh, with its intersecting tidal streams and rivers, provides excellent natural habitat for birds and mammals and serves as a nursery for marine organisms, and provides sporting or commercial value. The water levels in the refuge's impoundments are manipulated to produce desirable emergent and underwater plants for waterfowl. When the pools are drawn down, large populations of shore and wading birds feed on the mudflats.
Upland agricultural crops are grown on about 1,100 acres (4.5 km²) to provide additional food for waterfowl and other migratory birds.

Famous quotes containing the word topography:
“That the mere matter of a poem, for instance—its subject, its given incidents or situation; that the mere matter of a picture—the actual circumstances of an event, the actual topography of a landscape—should be nothing without the form, the spirit of the handling, that this form, this mode of handling, should become an end in itself, should penetrate every part of the matter;Mthis is what all art constantly strives after, and achieves in different degrees.”
—Walter Pater (1839–1894)
