Mottled duck habitat

Detailed Description

In hydrologically stressed Spartina patens marshes, plants begin to grow in hummocks, or areas of higher elevation. Over time, the hollows, or the low-lying unvegetated areas between the hummocks, continue to expand until the area is dominated by open water and the mottled duck habitat is lost.
