Early Succesional and Semi-Natural Habitats
General Wet Grasslands
No image for this habitat.
General Description This habitat includes a variety of wet to mesic, open grasslands, including both natural, successional, and semi-natural examples. Members of the Poaceae are dominant; wetter habitats that have a significant amount of sedges or rushes are included in the General Sedge, Grass, and Rush Mires.

Determining Species of this habitat include species that have a broad range across North Carolina. These include several species of grasses along with one Orthopteran that is found in wet grass-dominated habitats virtually anywhere in the state, from the fen on top of Bluff Mountain to the grassy edges of Patsy Pond in the Croatan National Forest.

Abiotic Factors Geographic Regions: High Mountins to the Lower Coastal Plain. USDA Hardiness Zones: 6-8. Landform: restricted to floodplains and wet flats. Soil Moisture: wet. Soil Texture: loamy, silty, sandy. Soil pH: usually acidic due to the build-up of humic acids. Soil Nutrients: generally poor with nutrient-rich examples found only in a few fens. . Microclimate: warm to cool, humid. Flood Frequency: several times per year. Flood Duration: transient. Presence of Pools: both permanent and ephemeral ponds and pools may imbedded withing this habitat. Fire Frequency: uncommon to frequent. Drought Frequency: rare. Insolation: partial to full sun

Biotic Structure Vegetation Type: grassland. Key Species species of graminoids are the dominant plant species in this habitat; forbs may also be present, but like woody species, occur only as scattered individuals or patches. Strata: some examples occur in wet, open woodlands but usually where there is no significant subcanopy or shrub layer. Woody Debris and Leaf Litter: dead leaves of the graminoids often accumulate to form dense thatch
