Department of Planning and Zoning
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 -

Ohio Trees for Bees Denise Ellsworth, Department of Entomology
OHIO STATE UNIVERSITY EXTENSION AGRICULTURE AND NATURAL RESOURCES FACT SHEET ENT-71-15 Ohio Trees for Bees Denise Ellsworth, Department of Entomology Many people are concerned about the health and survival of bees, including honey bees, native bumble bees and the hundreds of lesser-known native and wild bees that call Ohio home. Bees are threatened by an assortment of factors such as pests, pathogens, pesticides, climate change and a lack of nesting habitat and forage plants. Bees and flowering plants have a critical relationship. Flowering plants provide nectar and pollen for a bee’s diet. Pollen is an essential source of protein for developing bee larvae, and nectar provides a carbohydrate source. Honey bees convert nectar into honey by adding an enzyme which breaks down the complex sugars into simple sugars. Bees, in turn, transport pollen from flower to flower as they forage, allowing for plant fertilization and the production of seeds and fruit. While trees provide many well-known ecological benefits, the importance of trees as a source of food for bees is sometimes overlooked. Ohio trees can provide food for bees from early spring through late summer, with most tree species in Ohio blooming in spring and early summer. This fact sheet describes some of the Ohio trees that provide food for bees. Trees included in this list have been described as important by multiple researchers and bee experts. Other trees not listed here can also provide food for bees. For example, Ohio horticultural experts have noted significant bee foraging activity on trees such as Carolina silverbell (Halesia carolina), seven-son flower (Heptacodium miconioides), goldenrain tree (Koelreuteria paniculata) and Japanese pagoda tree (Styphnolobium japonicum) in landscape settings. -

Tree and Shrub Tolerance to De-Icing Salt Spray
Michigan State University Extension Home Horticulture - 03900109 01/01/96 TREE AND SHRUB TOLERANCE TO DE-ICING SALT SPRAY Over the past 10 to 15 years, trees and shrubs along major highways in Michigan and other northern states have shown dessication injuries. The damage varies with variety - those plants with sticky, pubescent, or sunken buds appear to be somewhat more tolerant than those plants with smooth, exposed buds. Tolerance to dessication can be attributed to a number of things -- for example, the tolerant evergreens may be protected from injury due to a thick coating of wax on their needles. It is much more difficult to characterize the tolerance nature of deciduous species, as Various deciduous species exhibit a malformation of growth like a witch's broom when injured. The cause of this injury is the salt spray that splashes or drifts onto roadside trees following highway de-icing operations. Damage is most prominent in urban areas and seems to be linked to more frequent salt applications and to traffic density. The symptoms are most pronounced on sensitive plants close to the highway, but have been observed some 250 feet down wind of the traffic. Sensitive plants may exhibit injury to a height of 20 to 25 feet, although lower branches protected by snow may escape injury. Depending upon the snow cover, a zone of injury may extend from three to eight feet above the ground to a height of 20 to 25 feet. Following is a summary of the average salt spray tolerances of various plants bordering selected Michigan highways. -

Vascular Flora and Vegetation Classification of the South Atlantic Coastal Plain Limestone Forest Association of Central Georgia
VASCULAR FLORA AND VEGETATION CLASSIFICATION OF THE SOUTH ATLANTIC COASTAL PLAIN LIMESTONE FOREST ASSOCIATION OF CENTRAL GEORGIA by PATRICK SUMNER LYNCH (Under the Direction of J.L. Hamrick) ABSTRACT The South Atlantic Coastal Plain Limestone forest is a globally imperiled (G2) forest association known only from the upper Coastal Plain of central Georgia. These calcareous forest communities support diverse floristic assemblages unique among the Georgia Coastal Plain, but have not been subject to detailed floristic study. I conducted a comprehensive floristic inventory, multivariate community analyses and floristic quality assessments to document composition, elucidate community structure and underlying physiographic regimes, and assess habitat integrity for seven sites in Houston, Bleckley and Twiggs counties. Community analyses revealed twelve community types within two floristically defined domains corresponding to uplands and slopes, and bottomlands, respectively, and governed largely by moisture content and degree of inclination. Floristic quality assessments revealed varying degrees of floristic quality and habitat integrity corresponding primarily to local physiography and disturbance history. Floristic inventory recovered 339 vascular plant taxa representing 218 genera in 98 families, including 17 rare Georgia species.

Abstract Goldenseal (Hydrastis canadensis L.) is a well-known perennial herb indigenous to forested areas in eastern North America. Owing to conservation concerns including wild harvesting for medicinal markets, habitat loss and degradation, and an overall patchy and often inexplicable absence in many regions, there is a need to better understand habitat factors that help determine the presence and distribution of goldenseal populations. In this study, flora and edaphic factors associated with goldenseal populations throughout Pennsylvania—a state near the northern edge of its range—were documented and analyzed to identify habitat indicators and provide possible in situ stewardship and farming (especially forest-based farming) guidance. -
The Phytochemistry of Cherokee Aromatic Medicinal Plants
medicines Review The Phytochemistry of Cherokee Aromatic Medicinal Plants William N. Setzer 1,2 1 Department of Chemistry, University of Alabama in Huntsville, Huntsville, AL 35899, USA; [email protected]; Tel.: +1-256-824-6519 2 Aromatic Plant Research Center, 230 N 1200 E, Suite 102, Lehi, UT 84043, USA Received: 25 October 2018; Accepted: 8 November 2018; Published: 12 November 2018 Abstract: Background: Native Americans have had a rich ethnobotanical heritage for treating diseases, ailments, and injuries. Cherokee traditional medicine has provided numerous aromatic and medicinal plants that not only were used by the Cherokee people, but were also adopted for use by European settlers in North America. Methods: The aim of this review was to examine the Cherokee ethnobotanical literature and the published phytochemical investigations on Cherokee medicinal plants and to correlate phytochemical constituents with traditional uses and biological activities. Results: Several Cherokee medicinal plants are still in use today as herbal medicines, including, for example, yarrow (Achillea millefolium), black cohosh (Cimicifuga racemosa), American ginseng (Panax quinquefolius), and blue skullcap (Scutellaria lateriflora). This review presents a summary of the traditional uses, phytochemical constituents, and biological activities of Cherokee aromatic and medicinal plants. Conclusions: The list is not complete, however, as there is still much work needed in phytochemical investigation and pharmacological evaluation of many traditional herbal medicines. Keywords: Cherokee; Native American; traditional herbal medicine; chemical constituents; pharmacology 1. Introduction Natural products have been an important source of medicinal agents throughout history and modern medicine continues to rely on traditional knowledge for treatment of human maladies [1]. Traditional medicines such as Traditional Chinese Medicine [2], Ayurvedic [3], and medicinal plants from Latin America [4] have proven to be rich resources of biologically active compounds and potential new drugs.
