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 -

Pure white spruce stands are infrequent in th fire-disturbed, montane boreal landscape. Geographic Range and Ecological Amplitudes Description White spruce is a medium-sized (occasionally >55 m tall), evergreen conifer, with a fairly symmetrical, conical crown, a regular branching pattern that often extends to the ground, and a smooth, dark gray, scaly bark. The wood of white spruce is light, straight grained, and resilient. It is used primarily for lumber and pulp. Geographic Range Geographic element: North American transcontinental-incomplete Distribution in Western North America: (north) in the Pacific region; north and central in the Cordilleran region Ecological Climatic amplitude: Amplitudes subarctic – subalpine boreal – montane boreal – (cool temperate) Orographic amplitude: montane – subalpine Occurrence in biogeoclimatic zones: SWB, (ESSF), MS, BWBS, SBS, SBPS, (IDF), (ICH), (northern CWH) Edaphic Amplitude Range of soil moisture regimes: (very dry) – moderately dry – slightly dry – fresh – moist – very moist – wet Range of soil nutrient regimes: (very poor) – poor – medium – rich – very rich In the BWBS zone, white spruce grows well on medium and rich sites providing a Moder humus formation exists. Wildfires are the major disturbance factor in re-establishing a white spruce stand when acidic Mors begin to develop, a humus form which favors the regeneration and growth of black spruce. Without the fires, the more shade-tolerant black spruce would become a dominant species and form a climatic climax stand. -

The usefulness of random amplified microsatellite polymorphism markers to study the genetic diversity and relationships among cultivars belonging to Prunus salicina and P. domestica and their wild relatives (P. insititia and P. spinosa) was investigated. A total of 226 of 234 bands were polymorphic (96.58%). The 226 random amplified microsatellite polymorphism markers were screened using 15 random amplified polymorphic DNA and inter-simple sequence repeat primers combinations for 54 Tunisian plum accessions. The percentage of polymorphic bands (96.58%), the resolving power of primers values (135.70), and the polymorphic information content demonstrated the efficiency of the primers used in this study. The genetic distances between accessions ranged from 0.18 to 0.79 with a mean of 0.24, suggesting a high level of genetic diversity at the intra- and interspecific levels.

ABSTRACT OF THESIS CHARACTERIZATION OF POLYPHENOL OXIDASE AND ANTIOXIDANTS FROM PAWPAW (ASIMINA TRIBOLA) FRUIT Crude polyphenol oxidase (PPO) was extracted from pawpaw (Asimina triloba) fruit. The enzyme exhibited a maximum activity at pH 6.5–7.0 and 5–20 °C, and had -1 a maximum catalysis rate (Vmax) of 0.1363 s and a reaction constant (Km) of 0.3266 M. It was almost completely inactivated when incubated at 80 °C for 10 min. Two isoforms of PPO (MW 28.2 and 38.3 kDa) were identified by Sephadex gel filtration chromatography and polyacrylamide gel electrophoresis. Both the concentration and the total activity of the two isoforms differed (P < 0.05) between seven genotypes of pawpaw tested. Thermal stability (92 °C, 1–5 min) and colorimetry (L* a* b*) analyses showed significant variations between genotypes. -
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. -
Native Or Suitable Plants City of Mccall
Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring. -
