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 -
Phytophthora Ramorum Sudden Oak Death Pathogen

Geographic Range: 4. Habitat Invaded: 5. Historical Status and Rate of Spread in Wisconsin: 6. Proportion of potential range occupied: II. Invasive in Similar Climate YES NO X Zones United States: In 14 coastal California Counties and in Curry County, Oregon. In nursery in Washington. Canada: Nursery in British Columbia. Europe: Germany, the Netherlands, the United Kingdom, Poland, Spain, France, Belgium, and Sweden. III. Invasive in Similar Habitat YES X NO Types IV. Habitat Affected 1. 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. National Risk Model and Map shows susceptible forest types in the mid-Atlantic region of the United States. -

Hornbeam Maple Acer Carpinifolium Rating: 0.0 ( 0 Votes)
Hornbeam maple Acer carpinifolium Rating: 0.0 ( 0 votes) This description is for Hornbeam maple (Acer carpinifolium): So named because the wood is tough like a beam made of horns; handy, should you ever need a beam made of horns but you're woefully low on horns. Acer carpinifolium, commonly known as the Hornbeam maple hails from Japan. A fairly small tree, growing no taller than about 10-15m. Unlike most other acers, this tree does not have lobed leaves. Instead it has ridged oval leaves with a serrated edge. They look similar to the leaves of the hornbean, hence the name. In the autumn this tree really shines as the leaves turn a vibrant shade of yellow. It's a very hardy tree that will grow in most soil types as long as it is fertile and well- drained.

Non-Native Trees and Large Shrubs for the Washington, D.C. Area
Green Spring Gardens 4603 Green Spring Rd ● Alexandria ● VA 22312 Phone: 703-642-5173 ● TTY: 703-803-3354 www.fairfaxcounty.gov/parks/greenspring NON - NATIVE TREES AND LARGE SHRUBS FOR THE WASHINGTON, D.C. AREA Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily. -

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). -

The recent wildfires in Oregon came within just a few miles of one of our major suppliers, and that has held things up just a little bit, but we do still expect two massive deliveries of beautiful new trees over the next 6-8 weeks. The perfect planting time is just a few weeks away now. New trees will be here just in time! We will send out an email and update the front page and the 'Inventory' page of our website when the shipments arrive. We have 'Fire Dragons' and 'Baby Dragons' and 'Super Dragons,' along with Shantung Seedlings and Trident Maples, so if you've got a sunny spot that needs a tree, we've got you covered. 'SUPER DRAGON' Acer truncatum 'Super Dragon' is one of several Shantung maples selected and patented by Metro Maples's founder, Keith Johansson. 'Super Dragon' is smaller than an average Shantung, reaching 15-18' tall and wide at maturity. The tree definitely likes to spread out, with strong lateral branching even in its youth. -

Tree Planting and Management
COMMONWEALTH WAR GRAVES COMMISSION Tree Planting and Management Breadth of Opportunity The spread of the Commission's responsibilities over some 148 countries in temperate, mediterranean, tropical and desert climates provides wonderful opportunities to experiment with nature's wealth of tree species. We are particularly fortunate in being able to grow many interesting and beautiful trees and we will explain how we manage them and what splendid specimens they can make. Why Plant Trees? Trees are planted for a variety of reasons: their amenity value, leaf shape and size, flowers, fruit, habit, form, bark, landscape value, shelter or screening, backcloth planting, shade, noise and pollution reduction, soil stabilisation and to encourage wild life. Often we plant trees solely for their amenity value. That is, the beauty of the tree itself. This can be from the leaves such as those in Robinia pseudoacacia 'Frisia', the flowers in the tropical tree Tabebuia or Albizia, the crimson stems of the sealing wax palm (Cyrtostachys renda), or the fruit as in Magnolia grandiflora. above: Sealing wax palms at Taiping War Cemetery, Malaysia with insert of the fruit of Magnolia grandiflora Selection Generally speaking the form of the left: The tropical tree Tabebuia tree is very often a major contributing factor and this, together with a sound knowledge of below: Flowers of the tropical the situation in which the tree is to tree Albizia julibrissin be grown, guides the decision to the best choice of species. Exposure is a major limitation to the free choice of species in northern Europe especially and trees such as Sorbus, Betula, Tilia, Fraxinus, Crataegus and fastigiate yews play an important role in any landscape design where the elements are seriously against a wider selection.
