Climate Change - Lower York River - Polyhaline (YRKPH)
CURRENT COASTAL HABITAT COMPOSITION
6.5 km² - Tidal Marsh
4.4 km² - Submerged Aquatic Vegetation
19.9 km² - Shallow Water
22.7 km - Beaches
The Lower York River segment is located in York and Gloucester Counties and extends from the river mouth to slightly upriver of Cheatham Annex. Much of the shoreline is developed (45% developed riparian lands (mostly residential), and 28% hardened shoreline). Both counties have moderate-high average annual rates of permitted shoreline hardening ranging from 0.9-1.3 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
