NR 120.14(16)(a)(a)
Description. Riparian buffers are areas in which vegetation is enhanced or established to reduce or eliminate the movement of sediment, nutrients and other nonpoint source pollutants to adjacent surface water resources or groundwater recharge areas and to protect the banks of streams and lakes from erosion and to protect fish habitat. This practice shall be implemented using one or more of the standards in
par. (c).
NR 120.14(16)(b)1.1. Cost-sharing may be provided only when the riparian buffers are used consistent with the approved priority watershed plan, priority lake plan or project grant application or approved priority watershed or lake plan.
NR 120.14(16)(b)2.b.

(19) Shoreline habitat restoration for developed areas. NR 120.14(19)(a)(a)
Description. Shoreline habitat restoration is the establishment in developed areas of a shoreline buffer zone of diverse native vegetation that extends inland and waterward from the ordinary high water mark. The shoreline habitat restoration design seeks to restore the functions provided by the original, natural vegetation, and includes a mixture of native trees, shrubs, ground cover or wetland species. This practice includes the following:
NR 120.14(19)(a)1.
1. Natural recovery. Used where native vegetation will recover naturally when a site is protected from disturbance, due to the presence of existing native plants, and adequate seed sources and site conditions. This method may be applied to wet margins of lakes or rivers where turf grasses are not well established and in shallow water areas adjacent to shoreland restoration areas.
NR 120.14(19)(a)2.
2. Accelerated recovery. Used in areas not suited for natural recovery. Native vegetation is established by seeding and planting. This method shall be used in areas where dense turf grasses have been maintained for several years. This may also be used in limited situations where one or more layers of natural vegetative cover have been removed if approved by the department. This practice shall be implemented using one or more of the standards in
par. (c).
NR 120.14(19)(b)1.1. Cost-sharing for shoreline habitat restoration may be approved when existing shoreline vegetation lacks the structure or complexity to support habitat functions for littoral and riparian areas.
NR 120.14(19)(b)2.
2. Cost-sharing may be provided for plants, seed, mulch and erosion control materials.
NR 120.14(19)(b)3.
3. Cost-sharing may be provided for labor and services necessary for installation, not to exceed 70% of total practice costs, or not to exceed a cost containment policy developed by the governmental unit for this practice.
