What is a wetland?Generally, a wetland is land that is periodically flooded, by the tide, the rise of river flows, rain, or--in some cases--human action. Among the several types of wetlands are marshes, swamps, rivers, vernal pools, lakes, and ponds. (State of California)
Why are wetlands important?
• Provide a Source of Water
• Flood Control and Groundwater Recharge
• Water Quality Protection and Improvement
• Erosion Control
• Fish and Wildlife Habitat
• Biological Diversity
• Recreation
Project Overview
• The primary objective of this project is to produce a full set of wetland and riparian habitat maps for the south coast region.
Methodological Consistency
Wetland & riparian habitat maps are consistent with statewide and national wetland inventories.
