Abstract
The habitat most likely to be negatively impacted by climate change in coastal Virginia over the next several decades is tidal marsh. Tidal marsh extent is dictated by the location of the intertidal area, which is rapidly changing as a result of climate change and tidal marshes must also rapidly adapt in order to persist on the landscape. Of the two primary mechanisms for tidal wetland adaptation: accretion and migration, migration is most likely for most marshes in Virginia. Migration occurs as the upland edge of the marsh moves further inland in response to rising sea level. As formerly upland areas become regularly inundated by spring tides, these areas convert to high marsh due to increasing salt content and saturation. This data depicts the land use/ land cover classification areas that will occur within the potential areal footprint of tidal wetlands (TW) for each decade from 2030 to 2100 and included 2020 as reference.
