Marshes, Mires, and Shoreline Habitats
General Shoreline Forblands
No image for this habitat.
General Description This habitat includes open to partially shaded shorelines of creeks, rivers, ponds, and lakes that support lush growths of herbaceous plants.

Determining Species include forbs that require constantly saturated, alluvial soils and that are tolerant of frequent inundation. Animal species include herbivores that are closely associated with the plant species of these habitats. In some cases, the plant hosts have not been documented but the records for the species are primarily from shoreline habitats.

Abiotic Factors Geographic Regions: Low Mountains to the Lower Coastal Plain. USDA Hardiness Zones: 6-8. Landform: occurring along perennial streams on slopes and along the edges of pools, ponds, and stream shorelines in floodplains and wet flats Soil Moisture: wet to hydric. Soil Texture: alluvial/loamy, silty, or sandy. Soil pH: acidic to circumneutral. Soil Nutrients: relatively poor to rich. Microclimate: warm to cool, humid. Flood Frequency: intermittent; this habitat occurs only where water is constantly present but usually not inundating. Flood Duration: permanently wet but only transiently flooded. Presence of Pools: both permanent and ephemeral ponds and pools may be used. Fire Frequency: rare to frequent on adjoining areas. Drought Frequency: rare. Insolation: partial to full sun

Biotic Structure Vegetation Type: forblands. Strata: often located at the edge of closed canopy forests but not growing directly beneath theme. Woody Debris and Leaf Litter: flood debris is common but leaf litter is typically washed away in floods

Expected Number of Extirpations with a PE value (Sum of PE) = 0.0033
N = Number of Extant Species with a PE value = 5
Average PE = ENE/N = 0.0007
Number of S5 species = 2
Proportion of Secure Species = Number of S5 Species/N = 0.4000
Habitat Risk Index = ENE x (1 – PSS) = 0.0020
