Summary

This dataset was originally developed to synthesize important natural resource information in one geospatial layer for natural resource management, land use management and awareness. The Nature Conservancy developed this update to incorporate into a protection prioritization model for climage change adaptation on the Virginia Eastern Shore

Description

This is an update of the Virginia Ecological Value Assessment (VEVA) originally completed in 2011 by the Virginia Coastal Zone Management Program and Virginia Department of Conservation and Recreation. VEVA integrates elements of the Priority Conservation Areas dataset, Healthy Waters data and VIMS Center for Coastal Resource Management Cumulative Resource Inventory. VEVA delineates priority conservation areas ranked by level of importance based on VA Dept. of Game and Inland Fisheries' Priority Wildlife Diversity Conservation Areas, VA Dept of Conservation and Recreation Division of Natural Heritage Conservation Sites Layer (CSL) and Natural Lands Network (NLN), VCU Center for Environmental Studies aquatic resource integrity layer and VIMS College of William and Mary Center for Coastal Resource Management Cumulative Resource Assessment. The Virginia Ecological Value Assessment builds on the definition of the Priority Conservation Areas and are defined as lands, aquatic resources and surface waters indentified as important for conservation of Virginia's wildlife, plants, and aquatic and natural communities. The identified lands, aquatic resources and waters can be used to prioritize areas for preservation, protection or specific management action.

The 2014 update was completed only for the Virginia Eastern Shore and incorporated updates to the Natural Heritage Conservation Sites and VCU aquatic resource integrity layers mentioned above.
