This community is not recommended for commercial woodland unless water control measures are provided. 5. Urbanland This community is subject to high water tables, especially during the rainy seasons. This causes limitations for urban development and water management systems are required. It is often difficult to establish vegetation on steep channel side slopes and infertile soils. Special planting and management techniques may be required. Without adequate vegetation, erosion and sedimentation is usually a problem. Severe wind erosion can also occur, especially in the spring. Native plants can be used for beautification and require minimum establishment and maintenance. Some of the shrubs are sawplametto and waxmyrtle. Some of the herbaceous plants are aster, cone flower, iris, marsh pink, and meadowbeauty. The most important urban wildlife are songbirds and wading birds. Undisturbed areas are important as refuge areas for many forms of wildlife.
