Virginia’s Natural Landscape Assessment

The Virginia Natural Heritage Program (VNHP) in the Department of Conservation and Recreation has developed a network of natural lands for the commonwealth of Virginia. This project, named the Virginia Natural Landscape Assessment (VaNLA), is a landscape-scale geospatial analysis for identifying, prioritizing, and linking natural lands in Virginia. Using land cover data derived from satellite…

Migratory Fish Spawning & Nursery Designated Use

Chesapeake Bay tidal waters support spawning areas and juvenile nurseries for a host of anadromous and semi-anadromous fish, such as striped bass and shad. These fish are important not only to Chesapeake Bay fishery populations, but also to those of the entire East Coast. The eggs, larvae and early juveniles of anadromous and semi-anadromous species…

Priority Living Resource Areas

The Chesapeake Bay Program’s target species listed in Habitat Requirements for Chesapeake Bay Living Resources, Second Edition (1991) which had habitat requirements that could be directly affected by nutrient over enrichment (e.g., dissolved oxygen) or sediments (e.g., light penetration) were arrayed by water column and bottom as their principal habitats. These included all the fish…

Watershed Categories

This map separates small watersheds of the Chesapeake Bay basin into eight classes based on the percentages of forest, agriculture and developed land covers from year 2000 satellite data within those watersheds. A similar map was published in the State of the Chesapeake Forests report.

Resource Lands Assessment – Vulnerability Model

Vulnerability Model – The vulnerability layer evaluates the relative potential risk of future land conversion to urban uses. Vulnerability is defined as a function of suitability for development and proximity to growth “hot spots.” The vulnerability layer is useful as a stand-alone layer to evaluate development trends, but can also be combined with the other…

Resource Lands Assessment – Prime Farmland Model

Prime Farmland Model – Assessing the extent of farming on prime soils in the Bay watershed is a useful measure for determining the lands of highest importance for agricultural productivity and sustainability. Areas of intense agricultural activity on prime soils can be overlaid with maps of development pressure to prioritize agricultural preservation activities.

Resource Lands Assessment – Water Quality Model

Water Quality Protection Model – The Water Quality model aims to identify forests and wetlands important in protecting water quality and sustaining watershed integrity. This “watershed value” is based on physical and biological functions that store precipitation, retain and assimilate nutrients, moderate runoff, protect soils and maintain important critical landscape functions such as those of…

Resource Lands Assessment – Forest Economics Model

Forest Economics Model – The identification of economically important forest lands focuses on the potential for future economic benefits associated with timber management activities. This considers not only the potential economic gain from forest harvest operations, but also the long-term economic sustainability of forest management and the local importance of the timber and wood products…

Resource Lands Assessment – Ecological Network

Ecological Network Model – The Ecological Network Assessment aims to identify the most important remaining habitats in the Virginia, Maryland, Pennsylvania, West Virginia, Delaware and D.C. portions of the Bay watershed. The assessment applies a “hubs and corridors” approach, which is based on principles of landscape ecology and conservation biology, that suggest that size and…

Resource Lands Assessment – Cultural Resources Model

Cultural Assessment Model – Growth and development not only threaten lands of high value for water quality and habitat, but also cultural lands that directly connect many citizens in the Bay watershed to the land. Important in preserving heritage and traditional values, cultural lands often define a sense of place. The objective of the cultural…
