Christopher Ludwig Nancy E. Van Alstine Virginia Department of Conservation and Recreation Division of Natural Heritage 203 Governor Street Richmond, Virginia 23219 for Northeast Region U.S. Fish and Wildlife Service One Gateway Center Newton Corner, Massachusetts 02158 Approved: ~ ~ ~4CsRegiona Director, ortheast Region U.S. Fish and Wil life Service Date: EXECUTIVE SUMMARY SHALE BARREN ROCK CRESS RECOVERY PLAN Current Status: Thirty-four extant populations and one historical population are known for this species, which was listed as endangered in August 1989. The extant populations are located in six Virginia and three West Virginia counties; the historical population was located in an additional Virginia county. Nineteen populations occur within the Monongahela and George Washington National Forests; of these, 13 have been proposed for further administrative protection. One Virginia population is owned and protected by the Commonwealth, and the protection needs of a West Virginia population on U.S. Navy land are being studied under a 5-year cooperative agreement. No protection has been initiated for the populations on private land. In addition to its Federal listing, the species is listed as endangered in Virginia. Limiting Factors: Arabis serotina is jeopardized by drought, habitat degradation, stochastic events, herbivory, and other biotic factors. Since most of the extant populations have under 100 plants and many have fewer than ten individuals, the species may be vulnerable to local extirpation. Recovery Obiective: To remove Arabis serotina from the list of endangered and threatened species.

  • Procedures for Conducting Surveys for Federally Threatened Or Endangered Plants in West Virginia
    Procedures for Conducting Surveys for Federally Threatened or Endangered Plants in West Virginia To assist in the review process for proposed actions that may affect federally listed threatened and endangered plants, the U.S. Fish and Wildlife Service (Service), West Virginia Field Office (WVFO) and the West Virginia Division of Natural Resources (WVDNR) have developed the following recommendations for conducting surveys for federally listed threatened and endangered plants, and for reporting of results. Field botanists or biologists experienced in conducting surveys for rare or federally listed plant species, and who have had training or experience in locating and identifying the specific federally listed species that may be present within a project area, should conduct surveys. A qualified surveyor should be present in the field at all times during the investigation. The WVFO and WVDNR maintain a list of qualified surveyors. Surveyors not on this list may be qualified, but should provide a resume and supporting information sufficient to document their qualifications to the WVFO and WVDNR prior to conducting the survey. The required documentation and process for this is described in How to Apply to Be Added to the List of Qualified Surveyors of Federally Listed Threatened and Endangered Plant Species in West Virginia. The qualified surveyor should coordinate with the WVDNR and WVFO to discuss survey plans prior to conducting the survey. Surveys should cover the entire area affected by the proposed project including areas outside the immediate area of direct impact that may be affected by project activities (changes in water levels, shading, or moisture; increased erosion or sedimentation, etc.).

Unpublished report. April 2009. 62 pages plus appendices. INTRODUCTION The Virginia Department of Conservation and Recreation's Division of Natural Heritage (DCR-DNH) was established to protect Virginia's Natural Heritage Resources. These Resources are defined in the Virginia Natural Area Preserves Act of 1989 (Section 10.1-209 through 217, Code of Virginia), as the habitat of rare, threatened, and endangered plant and animal species; exemplary natural communities, habitats, and ecosystems; and other natural features of the Commonwealth. DCR-DNH is the state's only comprehensive program for conservation of our natural heritage and includes an intensive statewide biological inventory, field surveys, electronic and manual database management, environmental review capabilities, and natural area protection and stewardship. Through such a comprehensive operation, the Division identifies Natural Heritage Resources which are in need of conservation attention while creating an efficient means of evaluating the impacts of economic growth. To achieve this protection, DCR-DNH maintains lists of the most significant elements of our natural diversity.

  • Survey Periods for Federally Listed Plants and Procedures for Positive Federally Listed Plant Surveys
    Survey Periods for Federally Listed Plants and Procedures for Positive Federally Listed Plant Surveys The U.S. Fish and Wildlife Service (Service), West Virginia Field Office (WVFO), has established the following acceptable survey periods for identifying threatened and endangered plants that occur in West Virginia. Surveys conducted during these time frames by approved surveyors should produce reliable results that will be accepted during environmental review. Surveys conducted outside of these periods may allow for identification of suitable habitat, but are not sufficient to confirm that these species are absent within suitable habitat. Negative surveys will be considered valid for two full survey periods from the year of the survey. For example, a survey conducted on July 31, 2012, would be valid through September 30, 2014. If work was to be conducted in a surveyed area after that date, additional surveys may be required.

  • Arabis Serotina) Is a Member of the Mustard Family
    TREES AND PLANTS SHALE-BARREN ROCKCRESS ABOUT The Shale-barren Rockcress (Arabis Serotina) is a member of the Mustard family. It is an erect flowering biennial (flowering every two years) adapted to dry conditions and most frequently found on eroding southern facing slopes. Because it is a biennial, it has two age stages: non- reproductive and reproductive. As a young plant, it has leaves in the shape of a rosette around its base. In its reproductive stage, the leaves at the bottom of the plant shrivel and the flowering stem produces 3 to 41 branches with small flowers of white or creamy petals that are produced from June to September. They die at the first killing frost. Mature plants reach a height of 16 to 40 inches. This plant needs to be pollinated, thereby reproducing sexually, and the primary pollinators include bees and syrphid (wasp-like) flies. Groupings of the Shale-barren Rockcress are small and generally number less than 20 individuals – although their number has been noticed to fluctuate considerably. DID YOU KNOW? The Shale-barren Rockcress is an endangered species and can only be found in West Virginia and Virginia on mid-Appalachian shale barrens of the Ridge and Valley Province of the Appalachian Mountains. These shale barrens are characterized by an open, scrubby growth of pine, oak, red cedar, and other woody species that like dry conditions. This plant is highly restricted in its habitat and cannot tolerate disturbance of its environment. Threats to this species include destruction of its habitat by construction of roads, railroads, hiking paths, and the damming of a stream totally destroyed one population site.

Description of the Virginia Department of Conservation and Recreation’s Division of Natural Heritage (with information on its mission, and the primary focus of collaborative activities to be supported through the CESU.) In July of 1988, the Virginia Division of Natural Heritage came under the direction of the Department of Conservation and Recreation (VaDCR) and in 1989 the General Assembly passed the Virginia Natural Area Preserves Act, formally naming VaDCR the agency responsible for the division. The act charges VaDCR with the responsibilities of conserving the biological diversity of Virginia, through biological inventory, maintaining a data bank of the information gathered through this inventory, and establishing a system of preserves dedicated to protecting biodiversity.
