    Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- ERICACEAE ERICACEAE (Heath Family) A family of about 107 genera and 3400 species, primarily shrubs, small trees, and subshrubs, nearly cosmopolitan. The Ericaceae is very important in our area, with a great diversity of genera and species, many of them rather narrowly endemic. Our area is one of the north temperate centers of diversity for the Ericaceae. Along with Quercus and Pinus, various members of this family are dominant in much of our landscape.

  • CT Coastal Planting Guide
    CONNECTICUT COASTAL PLANTING GUIDE Juliana Barrett Connecticut Sea Grant, University of Connecticut [email protected] CTSG-11-03 Connecticut Sea Grant College Program 2011 Connecticut Coastal Planting Guide This guide will be a useful tool for those interested in native landscaping within Connecticut’s coastal region. It contains a list of plants that will grow well along Long Island Sound and several miles inland. Connecticut’s coastal zone is defined here as the coastal ecoregion of Dowhan and Craig (1976) (Figure 1). An ecoregion is an area of similar landforms, climate, and biota. This region, divided below into eastern and western coastal ecoregions (V-A and V-B), extends 5 to 7 miles inland and has a long frost-free season (average approximately 180 days in the west, and 195 days in the east). Within this region, there are a wide variety of habitats and growing conditions, including tidal marshes and coastal forests, soils ranging from fine silts to sandy or rocky soils, and soil moisture conditions ranging from wet or moist to very dry. Vegetation in a particular area depends on a complex suite of site characteristics including geology and soils, local climate, topography, land use history and biotic factors. So the plants found growing in one location may be very different from those found one or two miles away. Figure 1. Ecoregions of Connecticut (from Dowhan, J. and R. Craig. 1976. Rare and endangered species of Connecticut and their habitats. Hartford, CT: Connecticut Geological and Natural History Survey. p. 135. 2 Connecticut Coastal Planting Guide Plants are categorized in the following list by growth form: tree, shrub, herbaceous perennial, or vine.

  • Report Prepared for the Ecosystem Enhancement Program, North Carolina Department of Environment and Natural Resources in Partial Fulfillments of Contract D07042
    Natural vegetation of the Carolinas: Classification and description of Mesic‐hydric plant communities north of the Albemarle Sound, North Carolina A report prepared for the Ecosystem Enhancement Program, North Carolina Department of Environment and Natural Resources in partial fulfillments of contract D07042. By M. Forbes Boyle, Robert K. Peet, Thomas R. Wentworth, and Michael P. Schafale Carolina Vegetation Survey Curriculum in Ecology, CB#3275 University of North Carolina Chapel Hill, NC 27599‐3275 Version 1. June 20, 2007 1 INTRODUCTION In terms of natural plant community composition, the coastal fringe area north of Albemarle Sound is a particular unusual and little documented region of North Carolina. The marshes here are primarily freshwater and the landscape is one of the embayed drainage basins, in part reflecting the rapid subsidence of land in this region. In spite of a general awareness of these wetland communities, there had not been any previous vigorous assessment of their composition and structure. Knowledge of the vegetation composition and structure of these communities can inform management decisions and direct future restoration projects. In July 2006, the Carolina Vegetation Survey conducted an initial floristic inventory of natural communities within the wetlands north of Albemarle Sound, North Carolina. The objectives of the study were to define and characterize the mesic to hydric vegetation of this poorly described area. Furthermore, the data captured from these plots will enable us to refine the community classification within the broader region. The goal of this report is to determine a classification structure based on the synthesis of vegetation data obtained from the July 2006 plots.

    The Vascular Flora of Sandy Run Savannas State Natural Area, Onslow and Pender Counties, North Carolina --In Press-- John B. Taggart Department of Environmental Studies, University of North Carolina at Wilmington, 601 South College Road, Wilmington, North Carolina 28403 ______________________________________________________________________________ ABSTRACT The vascular plants of Sandy Run Savannas State Natural Area, located in portions of Onslow and Pender counties, North Carolina, are presented as an annotated species list. A total of 590 taxa in 315 genera and 119 families were collected from eight plant communities. Families with the highest numbers of species were the Asteraceae (80), Poaceae (66), and Cyperaceae (65). Two species, Carex lutea (golden sedge) and Thalictrum cooleyi (Cooley’s meadowrue), have federal endangered status. A total of 23 taxa are tracked by the North Carolina Natural Heritage Program, while 29 others are considered rare, but not included on the priority list. Of 44 species considered strict endemic or near-endemic taxa to the North and South Carolina Coastal Plain, 18 (41%) were collected in this study. Selected pine savannas within the site were rated as nationally significant by the North Carolina Natural Heritage Program. Fifty-one (51) non-native species were present and represented 8.7 % of the flora. _________________________________________________________________________ INTRODUCTION Sandy Run Savannas State Natural Area encompasses portions of western Onslow and northeastern Pender counties in North Carolina. State acquisition of this coastal plain site began in 2007 as a cooperative effort between The Nature Conservancy in North Carolina and the North Carolina Division of Parks and Recreation to protect approximately 1,214 ha comprised of seven tracts (Figure 1).

  • Coastal Plain Depression Swamp (Pocosin Subtype)
    COASTAL PLAIN DEPRESSION SWAMP (POCOSIN SUBTYPE) Concept: Coastal Plain Depression Swamps are depressional wetlands with a well-developed, closed or nearly closed tree canopy of Taxodium ascendens or Nyssa biflora but without a dense graminoid-dominated herb layer. The Pocosin Subtype covers examples, generally in Carolina bays, with a dense shrub layer strongly dominated by the characteristic pocosin shrubs, mainly Cyrilla racemiflora, Lyonia lucida, Ilex glabra, and Zenobia pulverulenta, often along with Ilex amelanchier, Vaccinium formosum, and Vaccinium fuscatum. It is thus like a Small Depression Pocosin but with a well-developed swamp canopy. Distinguishing Features: Small Depression Swamp communities are distinguished from other Coastal Plain Depression Communities by the occurrence of a well-developed canopy of Taxodium ascendens or Nyssa biflora in a depressional wetland, without a well-developed herb layer. The Pocosin Subtype is distinguished by the dense pocosin-like shrub layer beneath a swamp canopy. Morella cerifera, Eubotrys racemosa, Itea virginica, and Leucothoe axillaris, and other species not typical of pocosins are absent or scarce, except that Vaccinium spp. or Ilex Amelanchier often are present. Small Depression Pocosins conceptually grade into this subtype; the distinction is based largely on canopy development but the type of basin is usually different as well. Synonyms: Taxodium ascendens / Cyrilla racemiflora - Zenobia pulverulenta Woodland (CEGL003734). Ecological Systems: Atlantic Coastal Plain Clay-Based Carolina Bay Wetland (CES203.245). Southern Atlantic Coastal Plain Depression Pondshore (CES203.262). Sites: The Pocosin Subtype occurs most often in Carolina bays, but is also known in limesink depressions and could potentially occur in dune swales. Soils: Sites usually have wet mineral soils, with or without a shallow organic layer.
