For the purposes of this chapter, the following words and phrases shall have the following meanings:
“Ecosystem”
means a system made up of a community of organisms and its interrelated physical and chemical environment.
“Enhancement”
means actions performed to improve the condition of existing wetlands or riparian area so that the functions they provide are additional and are of a higher value.
“Functions”
means the beneficial roles served by wetlands or riparian habitat including but not limited to, water quality protection and enhancement, fish and wildlife habitat, food chain support, flood storage, conveyance and attenuation, groundwater recharge and discharge, erosion control, aesthetic value protection, and recreation. These beneficial roles are not listed in order of priority.
“Riparian habitat”
means an ecosystem associated with the banks and other land adjacent to freshwater bodies, rivers, streams, creeks and surface-emergent aquifers (such as springs and seeps). Riparian habitat is characterized by plant and animal communities which require high soil moisture conditions maintained by transported freshwater in excess of that otherwise available through local precipitation.
“Wetland buffer areas”
means land surrounding wetlands which provides area of an appropriate size to protect the environmental and functional habitat values of the wetland, or which are integrally important in supporting the full range of the wetland and adjacent upland biological community.
“Wetlands”
means lands transitional between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is covered by permanent or seasonal shallow water. For the purposes of this definition, wetlands are those lands that have all of the following attributes:
1.
At least periodically, the land supports predominantly hydrophytes;
2.
The substrate is predominantly undrained hydric soil; and
3.
The substrate is nonsoil and is saturated with water or covered by shallow water at some time during the growing season of each year.
