Climate Change - Mobjack Bay - Polyhaline (MOBPH)
CURRENT COASTAL HABITAT COMPOSITION
56.9 km² - Tidal Marsh
50.7 km² - Submerged Aquatic Vegetation
111.6 km² - Shallow Water
39.9 km - Beaches
The Mobjack Bay and surrounds are located in Gloucester, Mathews, York, Poquoson and Hampton Counties. The segment includes East, North, Ware, Severn, Poquoson, and Back rivers, Guinea Marshes, Goodwin Islands, and the mouth of the York River. Much of the surveyed shoreline (913 km) is undeveloped (25% developed riparian lands and 6% hardened shoreline). All counties have moderate-high average annual rates of permitted shoreline hardening ranging from 0.4-1.5 km/yr (0.2-0.3% of the shoreline).
COASTAL HABITATS SHIFTS WITH CLIMATE CHANGE
-
Shallow-Water and Tidal Wetlands - depiction of existing tidal wetland (vegetated & non-vegetated) and shallow-water habitat, with projected shifts due to sea level rise
-
Tidal Marsh Vulnerability - depiction of existing tidal marsh and vulnerability to inundation from projected sea level rise within 50-100 years. Marshes classified at low risk represent potential wetland preservation opportunities
-
Estuarine Beach Vulnerability - depiction of existing estuarine beach and vulnerability to inundation from projected sea level rise within 50-100 years. Beaches classified at low risk represent potential habitat preservation opportunities
- Submerged Aquatic Vegetation - depiction of existing submerged aquatic vegetation (SAV) and projected shifts due to sea level rise and elevated temperatures
