    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

  • Amelanchier Canadensis: Shadblow Serviceberry1 Edward F
    ENH233 Amelanchier canadensis: Shadblow Serviceberry1 Edward F. Gilman and Dennis G. Watson2 Introduction Availability: somewhat available, may have to go out of the region to find the tree Downy serviceberry is an upright, twiggy, multi-stemmed large shrub, eventually reaching 20 to 25 feet in height with a spread of 15 to 20 feet. This North American native is usually the first to be noticed in the forest or garden at springtime, the pure white, glistening flowers some of the earliest to appear among the many other dull brown, leafless, and still-slumbering trees. The small white flowers are produced in dense, erect, two- to three-inch-long racemes, opening up to a delicate display before the attrac- tive reddish-purple buds unfold into small, rounded leaves. These leaves are covered with a fine, soft grey fuzz when young, giving the plant its common name, but will mature into smooth, dark green leaves later. Following the blooms are many small, luscious, dark red/purple, sweet and juicy, apple-shaped fruits, often well hidden by the dark green leaves, and which would be popular with people were they not so quickly consumed by birds and other wildlife who seem to find their flavor irresistible. General Information Figure 1.

  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe.

  • Aquatic Vascular Plant Species Distribution Maps
    Appendix 11.5.1: Aquatic Vascular Plant Species Distribution Maps These distribution maps are for 116 aquatic vascular macrophyte species (Table 1). Aquatic designation follows habitat descriptions in Haines and Vining (1998), and includes submergent, floating and some emergent species. See Appendix 11.4 for list of species. Also included in Appendix 11.4 is the number of HUC-10 watersheds from which each taxon has been recorded, and the county-level distributions. Data are from nine sources, as compiled in the MABP database (plus a few additional records derived from ancilliary information contained in reports from two fisheries surveys in the Upper St. John basin organized by The Nature Conservancy). With the exception of the University of Maine herbarium records, most locations represent point samples (coordinates were provided in data sources or derived by MABP from site descriptions in data sources). The herbarium data are identified only to township. In the species distribution maps, town-level records are indicated by center-points (centroids). Figure 1 on this page shows as polygons the towns where taxon records are identified only at the town level.

  • Oral Allergy Syndrome: a Confuence of Immunology and Phylogeny by Merle K
    NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE Oral Allergy Syndrome: A Confuence of Immunology and Phylogeny by Merle K. Heidemann, Mike S. Taylor, Amanda Storm, Cassie Dresser-Briggs, Alexa Warwick, and Peter J.T. White Objectives Upon completion of this case study, you should be able to: • Explain the symptoms of allergic reactions in terms of cell biology (immune system cells). • Describe the molecular features of cross reactivity. • Build phylogenetic trees using morphological data. • Build phylogenetic trees using molecular data and interpret two kinds of phylogenetic trees. Part I – Immunology Sam had a history of allergic reactions, including reactions to various plant pollens. Birch pollen elicited a particularly strong reaction, causing him annoying sneezing fts and a sore throat. As he grew to adulthood, he discovered that he was also variably allergic to common foods, including some raw fruits and vegetables, as well as most nuts. Sam was puzzled by his recent food allergies. Also puzzling was the variability in his reactions. He reacted strongly to some foods; others resulted in only a mild itchy throat. He wondered, What exactly causes allergic reactions? Sam was determined to fgure out how and why he reacted to birch pollen and later became allergic to other plant- based food. He also hoped this information might help him avoid other foods that might cause him allergies. First, Sam decided he needed to know something about the cellular bases of allergic reactions. He knew it had some- thing to do with the immune system. He did some basic research on the Internet and here’s what he found: Allergens are bits of protein from an innocuous foreign substance, such as pollen or food.
