birds. Artificially created dikes to control salinity are used in
 managing marsh plants for wildlife. Prescribed burning is also a
 technique used in marsh management.

4. Woodland

 These soils are unsuited to commercial wood production.

5. Urbanland

 This community is subject to a high water table and periodic flooding. It
 therefore has very severe limitations for urban development. Very
 elaborate water management systems are required for urban uses. It is
 difficult to establish salt tolerant vegetation on steep channel side
 slopes and infertile spoil. Special techniques such as mulching and
 unusual seeding and management techniques will be required. Without
 vegetation, erosion and sedimentation become a problem. Intensive
 measures may also be required to maintain design capacity.

 Native plants can be used for beautification and require minimum
 establishment and maintenance. Some of the trees and shrubs are black
 mangrove, button mangrove, necklace pod, sea oxeye, southern redcedar, and
 white mangrove. Some of the herbaceous plants are aster and goldenrod.
 Some of the grasses are cordgrasses, seashore dropseed, and seashore
 saltgrass.

 The most important urban related wildlife are waterfowl and water-adapted
 reptiles and mammals. Undisturbed areas provide good escape cover and
 travel routes for many forms of wildlife.
