    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

Habitat affected: this disease thrives in cool, wet climates including areas in coastal California within the fog belt or in low- lying forested areas along stream beds and other bodies of water. Oaks associated with understory species that are susceptible to foliar infections are at higher risk of becoming infected. 2. Host plants: Forty-five hosts are regulated for this disease. These hosts have been found naturally infected by P. ramorum and have had Koch’s postulates completed, reviewed and accepted. Approximately fifty-nine species are associated with Phytophthora ramorum. These species are found naturally infected; P. ramorum has been cultured or detected with PCR but Koch’s postulates have not been completed or documented and reviewed. Northern red oak (Quercus rubra) is considered an associated host. See end of document for complete list of plant hosts.

  • Status of Red Panda in Sikkim: a Case Study in East Sikkim
    STATUS OF RED PANDA IN SIKKIM: A CASE STUDY IN EAST SIKKIM Partha S. Ghose, Basant K. Sharma, Rajarshi Chakraborty and Karma Legshey D. ABSTRACT ed panda is the state animal of Sikkim and its population in the wild is highly vulnerable globally. Very little is known about red panda from Sikkim. With this background in mind the present collaborative survey by WWF- RIndia and Forest Environment and Wildlife Management Department, Government of Sikkim was initiated since 2005 to understand red panda's status in the wild and threats they are exposed to. The present work was conducted at three protected areas of East District and the results were subsequently used to assess the extent of red panda habitat in East District. Our results show that bamboo presence and cover emerged as the essential habitat feature to support red panda population. Among forest types mixed conifer was best suited for red pandas, followed by oak forests. However, conifer forest unlike the most beliefs did not emerge as the best possible habitat feature. The threat issues observed during the survey were discussed. KEYWORDS: Red panda, Sikkim, mixed conifer, oak forest, feral dogs, threats Red Panda photographed at Chowkidara Phedi-Pangolakha Wild Life Sanctuary 363 Red panda sighted at Pangolakha Ridge Top INTRODUCTION ed panda is a unique carnivore that has adapted to the herbivore mode of life and is a resident of Himalayan and Hengduan mountain ranges (Roberts and Gittleman, 1984; Glatston, 1994; Wei et al., 1999; Chowdhury, 2001). RLike its phylogenetic position, status of the red panda in wild has also been a matter of great discussion and speculation for over a long period (Glatston, 1994).

About 129 species: widespread in both temperate and tropical regions of N Africa, Asia, Europe, and Central and North America; 99 species (61 endemic, three introduced) in China. Acer lanceolatum Molliard (Bull. Soc. Bot. France 50: 134. 1903), described from Guangxi, is an uncertain species and is therefore not accepted here. The type specimen, in Berlin (B), has been destroyed. Up to now, no additional specimens have been found that could help clarify the application of this name. Worldwide, Japanese maples are famous for their autumn color, and there are over 400 cultivars. Also, many Chinese maple trees have beautiful autumn colors and have been cultivated widely in Chinese gardens, such as Acer buergerianum, A. davidii, A. duplicatoserratum, A. griseum, A. pictum, A. tataricum subsp. ginnala, A. triflorum, A. truncatum, and A. wilsonii.

Department of Horticulture Corvallis, OR 97331-7304 Oregon State University Voice: 541-737-5462 [email protected] Background: Prunus laurocerasus (common cherrylaurel) and P. lusitanica (portugese cherrylaurel), collectively referred to as cherrylaurels, are closely related species that are widely grown in the nursery industry and commonly planted in landscapes of the Pacific Northwest and other regions across the U.S. Using the Oregon Association of Nurseries Directory and Buyers' Guide (OAN-DBG) combined with the Nursery Appraisal Software for the Federal Crop Insurance Corporation for 2011 (http://www.rma.usda.gov/tools/eplpps/) we estimated a range for the number and value of cherrylaurels being grown in Oregon. Cumulatively, the estimated value of cherrylaurels for 2011 in Oregon alone is between $17.1 and $36.4 million. Common cherrylaurel is a handsome evergreen hedge plant native to Southeastern Europe and Asia Minor that is pH adaptable, does well in full sun or deep shade, is salt spray tolerant, and withstands heavy pruning. There are more than 45 cultivars in the trade including the popular 'Otto Luyken'.

  • Abies Concolor (White Fir)
    Compiled here is distribution, characteristics and other information on host species featured as ‘Host of the Month’ in past issues of the COMTF Monthly Report. Abies concolor (white fir) This is an evergreen tree native to the mountains of southern Oregon, California, the southern Rocky Mountains, and Baja California. Large and symmetrical, white fir grows 80 – 120ft tall and 15 – 20ft wide in its native range and in the Pacific Northwest. White fir is one of the top timber species found in the Sierra Nevada Mountains of CA and is a popular Christmas tree, as well as one of the most commonly grown native firs in Western gardens. Young trees are conical in shape, but develop a dome-like crown with age. The flattened needles of white fir are silvery blue-green, blunt at the tip , and grow 2 – 3in long. Often curving upwards, the needles extend at right angles from the twig, and twigs produce a citrus smell when needles are broken. White fir is monoecious, producing yellow- to red-toned, catkin-like male flowers and inconspicuous yellow-brown female flowers. The oblong cones grow 3 – 5 in upright, are yellow-green to purple in color, and are deciduous at maturity, dispersing seed in the fall. New twigs are dark- orange, but become gray-green, then gray with maturity. The bark of saplings is thin, smooth, and gray, turning thick, ash-gray with age, and developing deep irregular furrows. P. ramorum- infected Abies concolor (white fir) was first reported in the October 2005 COMTF newsletter as having been found at a Christmas tree farm in the quarantined county of Santa Clara.

It also references the combined results from three previous seasons (2011, 2012, and 2013) of research on English holly (Ilex aquifolium) at the same site, reported in Stokes (2014), Stokes et al. (2014a & b), and Lopez and Stokes (2016). 1 Address questions and comments to [email protected] 1 Mar. 9, 2017: Stokes, Lopez, and Thiel; Invasive Prunus spp. in St. Edward Park SUMMARY We located and removed all cherry laurel Prunus laurocerasus and Portuguese laurel P. lusitanica from a 9.2 hectare (22.8 acre) area of St. Edward State Park in January – March, 2015. This was the same study area where English holly Ilex aquifolium was located and removed in 2011 - 2013 (Stokes et al. 2014b). A total of 231 P. laurocerasus (25.1/ha) and 22 P. lusitanica (2.4/ha) were located and removed. Age of trees in our sample, determined by annual ring counts of basal cross-sections, ranged from 1 to 35 years for P. laurocerasus, and 1 to 21 years for P.
