4 F9 - Maintain of Native Plant Community General form of the model is: FCI = [(V SPPCOMP * V REGEN * 0.33) + V EXOTIC ]/2, where; V SPPCOMP : Floristic Quality Assessment Index (FQAI) V REGEN : regeneration of native tree species V EXOTIC : percent exotic species

8 Penn State Cooperative Wetlands Center F12 - Maintenance of Landscape Scale Diversity General form of the model is (within 1-km radius): FCI = (V AQCON + V UNDEVEL + V SDI + V MPS )/4 V AQCON : degree of aquatic connectivity (100-yr floodplain, stream density, nearest NWI wetland) V UNDEVEL : average of two sub-variables: V RDDEN - density of roads in 1-km radius circle V URB - % of 1-km radius circle in urban development V SDI : natural log of the Shannon diversity index of 8 landscape categories V MPS : mean forested patch size within a 1-km radius circle

10 Inventory ConditionRestoration Map landuse in watershed; calculate preliminary landscape measures Synoptic map of restoration potential (existing wetlands, landuse, roads & streams) Level 1 Level 2 Level 3 Utilize existing resources (NWI) Map of abundance zones with verified inventory Apply HGM functional assessment models to probability based sampling locations Map depicting abundance zones,verified inventory, and probable condition Performance criteria matrices provide restoration standards Develop and apply landscape-based approach to obtain abundance map Apply stressor checklist Map depicting overlay of wetland abundance zones, levels of potential threat, and landuse, roads & streams
