  • Introduction to the Southern Blue Ridge Ecoregional Conservation Plan
    SOUTHERN BLUE RIDGE ECOREGIONAL CONSERVATION PLAN Summary and Implementation Document March 2000 THE NATURE CONSERVANCY and the SOUTHERN APPALACHIAN FOREST COALITION Southern Blue Ridge Ecoregional Conservation Plan Summary and Implementation Document Citation: The Nature Conservancy and Southern Appalachian Forest Coalition. 2000. Southern Blue Ridge Ecoregional Conservation Plan: Summary and Implementation Document. The Nature Conservancy: Durham, North Carolina. This document was produced in partnership by the following three conservation organizations: The Nature Conservancy is a nonprofit conservation organization with the mission to preserve plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive. The Southern Appalachian Forest Coalition is a nonprofit organization that works to preserve, protect, and pass on the irreplaceable heritage of the region’s National Forests and mountain landscapes. The Association for Biodiversity Information is an organization dedicated to providing information for protecting the diversity of life on Earth. ABI is an independent nonprofit organization created in collaboration with the Network of Natural Heritage Programs and Conservation Data Centers and The Nature Conservancy, and is a leading source of reliable information on species and ecosystems for use in conservation and land use planning. Photocredits: Robert D. Sutter, The Nature Conservancy EXECUTIVE SUMMARY This first iteration of an ecoregional plan for the Southern Blue Ridge is a compendium of hypotheses on how to conserve species nearest extinction, rare and common natural communities and the rich and diverse biodiversity in the ecoregion. The plan identifies a portfolio of sites that is a vision for conservation action, enabling practitioners to set priorities among sites and develop site-specific and multi-site conservation strategies.

  • Native Plants for Piedmont Rock Gardens by Margo Macintyre
    V OLUME 26, I SSUE 2 F EBRUARY 2016 Piedmont Chapter North American Rock Garden Society The Trillium Chapel Hill, Durham, Raleigh, NC Native Plants for Piedmont Rock Gardens by Margo MacIntyre When Marian called to ask me to write an article about native plants for rock gardens for the Tril- lium, a wave of nostalgia hit me. During my college years and later, my Mom enthusiastically reported on the goings-on in the Piedmont Chapter of NARGS. Many times when I was home visiting from my gardening work at the Mt. Cuba Center in Delaware or Hurley Park in Salisbury, I attended Rock Gar- den Society meetings in Chapel Hill. Mom created what I call a rough draft of a rock garden on a bank filled with rocks she brought in and placed. The bank is perhaps two feet high and it tapers into the woods. It was created with rocks from Chatham County and was home to many small bulbs, low and creeping shrubbery, ferns and small perennials. The shady ends contained choice spring wildflowers, some of which remain today, still nes- tled among moss-covered rocks. Since the garden has not been tended in over a decade, it’s safe to say that these gems stand the test of time. Erythronium americanum, troutlily, Claytonia virginica, spring beauty, Silene virginica, firepink and Mitchella repens, partridgeberry, grace the small hillside. The Erythronium and Claytonia seeded into the lawn with reckless abandon. All of these residents of our local woodlands are available from local and mail order native plant sources and they are easy to grow.

He served as editor of The Farm journal for many years, and wrote several books on American history.
