    Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

  • Rare Native Animals of RI
    RARE NATIVE ANIMALS OF RHODE ISLAND Revised: March, 2006 ABOUT THIS LIST The list is divided by vertebrates and invertebrates and is arranged taxonomically according to the recognized authority cited before each group. Appropriate synonomy is included where names have changed since publication of the cited authority. The Natural Heritage Program's Rare Native Plants of Rhode Island includes an estimate of the number of "extant populations" for each listed plant species, a figure which has been helpful in assessing the health of each species. Because animals are mobile, some exhibiting annual long-distance migrations, it is not possible to derive a population index that can be applied to all animal groups. The status assigned to each species (see definitions below) provides some indication of its range, relative abundance, and vulnerability to decline. More specific and pertinent data is available from the Natural Heritage Program, the Rhode Island Endangered Species Program, and the Rhode Island Natural History Survey. STATUS. The status of each species is designated by letter codes as defined: (FE) Federally Endangered (7 species currently listed) (FT) Federally Threatened (2 species currently listed) (SE) State Endangered Native species in imminent danger of extirpation from Rhode Island. These taxa may meet one or more of the following criteria: 1. Formerly considered by the U.S. Fish and Wildlife Service for Federal listing as endangered or threatened. 2. Known from an estimated 1-2 total populations in the state. 3. Apparently globally rare or threatened; estimated at 100 or fewer populations range-wide. Animals listed as State Endangered are protected under the provisions of the Rhode Island State Endangered Species Act, Title 20 of the General Laws of the State of Rhode Island.

Eight species of Dragonflies, fourteen species of Butterflies, and eighteen species of beetles are identified . No threatened or endangered species were found in this survey during twenty-four hours of field observations . The area is undoubtedly home to many more species than those listed in this report. Of note, the endangered Karner Blue butterfly, Lycaeides melissa samuelis Nabakov was not seen even though it has been reported from Illinois Beach State Park, Lake County . The larval food plant, Lupinus perennis, for the blue was not observed at Waukegan. The limestone seeps habitat of the endangered Hines Emerald dragonfly, Somatochlora hineana, is not part of the ecology here . One surprise is the. breeding population of Buckeye butterflies, Junonia coenid (Hubner) which may be feeding on Purple Loosestrife . The specimens collected in this study are deposited in the insect collection at the Field Museum .

  • This Site Captures Roadside Habitat and Surrounding Second-Growth
    Seldom Seen Corners CA This site captures roadside habitat and surrounding second-growth deciduous forest that supports populations of Indian skipper butterfly ( Hesperia sassacus ) and long dash butterfly ( Polites mystic ), invertebrate species of conservation concern in Pennsylvania. Butterflies undergo four stages in their life cycle: egg, caterpillar, pupa, and adult. Once an adult female has mated, she seeks out the species of host plant appropriate for her species on which to lay her fertilized eggs. Most species lay their eggs on a plant that the newly hatched caterpillar will eat. When an egg hatches, a small caterpillar emerges and spends all its time eating and growing. As a caterpillar grows, it sheds its exoskeleton – usually three or four times – over Indian skipper butterfly. Photo: Will Cook the course of two to three weeks. During the caterpillar stage, the animal is highly vulnerable to predation by wasps and birds, parasitization by wasps or flies, or infection by fungal or viral pathogens; most caterpillars do not survive to the next stage of development. Once a caterpillar has reached full size, it attaches itself to a support and encases itself in a hard outer shell (chrysalis), and becomes a pupa. While in the pupa stage, the butterfly transforms into an adult. When the adult inside the chrysalis is fully formed, the chrysalis splits and the adult butterfly emerges (Glassberg 1999). Habitat for Indian skipper is old fields, pastures, and clearings. The caterpillars live in silken tubes at the base of grass clumps and leave them to feed. The older caterpillars overwinter and in the spring pupate in a loose cocoon.

  • Betula Nigra River Birch
    Betula nigra River Birch Betula nigra is a large, deciduous tree with the potential for growing to 25m tall with a wide, ovoid crown and gracefully arching branches. It is probably best known for the beautiful pink-brown bark which exfoliates to reveal a creamy white underneath and gives a fantastic display all year round. The leaves are ovate, with a serrated margin, typical of the Betula genus. Along with attractive yellow catkins, they emerge a vibrant lime green, heralding the start of spring, and darken as the season progresses. River birch also has a good autumn colour in shades of buttery yellow. Native to the swamps and river banks of NE America, Betula nigra grows well on wet ground. It will grow well in full sun and once established, is one of the few Birches that can tolerate heat extremely well. Betula nigra is available from Deepdale Trees as a standard or as a multistem. The multistem form shows off the brilliant bark to particularly good effect. Beautiful, peeling bark provides year round interest Plant Profile Name: Betula nigra Common Name: River Birch Family: Betulaceae Height: 20-25m Demands: Nutritious soil, moist soil in full sun Foliage: Diamond shaped leaves, bright green in spring, yellow in autumn Flower: Yellow catkins in early spring just before the leaves emerge Bark: The most appealing feature, cinnamon coloured peeling in curly strips to reveal oranges and creams underneath.
