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 -
Letter from the Desk of David Challinor August 2001 About 1,000
Letter From the Desk of David Challinor August 2001 About 1,000 miles west of the mid-Atlantic Ridge at latitude 32°20' north (roughly Charleston, SC), lies a small, isolated archipelago some 600 miles off the US coast. Bermuda is the only portion of a large, relatively shallow area or bank that reaches the surface. This bank intrudes into the much deeper Northwestern Atlantic Basin, an oceanic depression averaging some 6,000 m deep. A few kilometers off Bermuda's south shore, the depth of the ocean slopes precipitously to several hundred meters. Bermuda's geographic isolation has caused many endemic plants to evolve independently from their close relatives on the US mainland. This month's letter will continue the theme of last month's about Iceland and will illustrate the joys and rewards of longevity that enable us to witness what appears to be the beginnings of landscape changes. In the case of Bermuda, I have watched for more than 40 years a scientist trying to encourage an endemic tree's resistance to an introduced pathogen. My first Bermuda visit was in the spring of 1931. At that time the archipelago was covered with Bermuda cedar ( Juniperus bermudiana ). This endemic species was extraordinarily well adapted to the limestone soil and sank its roots deep into crevices of the atoll's coral rock foundation. The juniper's relatively low height, (it grows only 50' high in sheltered locations), protected it from "blow down," a frequent risk to trees in this hurricane-prone area. Juniper regenerated easily and its wood was used in construction, furniture, and for centuries in local boat building. -

Contributions to the Life-History of Tetraclinis Articu- Lata, Masters, with Some Notes on the Phylogeny of the Cupressoideae and Callitroideae
Contributions to the Life-history of Tetraclinis articu- lata, Masters, with some Notes on the Phylogeny of the Cupressoideae and Callitroideae. BY W. T. SAXTON, M.A., F.L.S., Professor of Botany at the Ahmedabad Institute of Science, India. With Plates XLIV-XLVI and nine Figures in the Text. INTRODUCTION. HE Gum Sandarach tree of Morocco and Algeria has been well known T to botanists from very early times. Some account of it is given by Hooker and Ball (20), who speak of the beauty and durability of the wood, and state that they consider the tree to be probably correctly identified with the Bvlov of the Odyssey (v. 60),1 and with the Ovlov and Ovia of Theo- phrastus (' Hist. PI.' v. 3, 7)/ as well as, undoubtedly, with the Citrus wood of the Romans. The largest trees met with by them, growing in an un- cultivated state, were about 30 feet high. The resin, known as sandarach, is stated to be collected by the Moors and exported to Europe, where it is used as a varnish. They quote Shaw (49 a and b) as having described and figured the tree under the name of Thuja articulata, in his ' Travels in Barbary'; this statement, however, is not accurate. In both editions of the work cited the plant is figured and described as ' Cupressus fructu quadri- valvi, foliis Equiseti instar articulatis '. Some interesting particulars of the use of the timber are given by Hansen (19), who also implies that the embryo has from three to six cotyledons. Both Hooker and Ball, and Hansen, followed by almost all others who have studied the plant, speak of it as Callitris qtiadrivalvis. -

Management of Threatened, High Conservation Value, Forest Hotspots Under Changing Fire Regimes
Chapter 11 Management of Threatened, High Conservation Value, Forest Hotspots Under Changing Fire Regimes Margarita Arianoutsou , Vittorio Leone , Daniel Moya , Raffaella Lovreglio , Pinelopi Delipetrou , and Jorge de las Heras 11.1 The Biodiversity Hotspots of the Earth Biodiversity hotspots are geographic areas that have high levels of species diversity but signifi cant habitat loss. The term was coined by Norman Myers to indicate areas of the globe which should be a conservation priority (Myers 1988 ) . A biodiversity hotspot can therefore be defi ned as a region with a high proportion of endemic species that has already lost a signifi cant part of its geographic original extent. Each hotspot is a biogeographic unit and features specifi c biota or communities. The current tally includes 34 hotspots (Fig. 11.1 ) where over half of the plant species and 42% of terrestrial vertebrate species are endemic. Such hotspots account for more than 60% of the world’s known plant, bird, mammal, reptile, and amphibian M.

Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

Highlights • The employment of ISSR molecular markers has shown moderate genetic diversity and high genetic differentiation in Tetraclinis articulata. • Genetic structure of populations seems to be influenced by the anthropogenic use of this species since historical times, or alternatively, by the complex palaeogeographic history of the Mediterranean basin. • Results could be used to propose management policies for conservation of populations. Abstract Tetraclinis articulata (Vahl) Masters is a tree distributed throughout the western Mediterranean basin. It is included in the IUCN (International Union for Conservation of Nature) red list, and protected by law in several of the countries where it grows. In this study we examined the genetic diversity and genetic structure of 14 populations of T. articulata in its whole geographic range using ISSR (inter simple sequence repeat) markers. T. articulata showed moderate genetic diversity at intrapopulation level and high genetic differentiation. The distribution of genetic diversity among populations did not exhibit a linear pattern related to geographic distances, since all analyses (principal coordinate analysis, Unweighted pair group method with arithmetic mean dendrogram and Bayesian structure analysis) revealed that spanish population grouped with Malta and Tunisia populations. -
IUCN Red List of Threatened Species™ to Identify the Level of Threat to Plants
Ex-Situ Conservation at Scott Arboretum Public gardens and arboreta are more than just pretty places. They serve as an insurance policy for the future through their well managed ex situ collections. Ex situ conservation focuses on safeguarding species by keeping them in places such as seed banks or living collections. In situ means "on site", so in situ conservation is the conservation of species diversity within normal and natural habitats and ecosystems. The Scott Arboretum is a member of Botanical Gardens Conservation International (BGCI), which works with botanic gardens around the world and other conservation partners to secure plant diversity for the benefit of people and the planet. The aim of BGCI is to ensure that threatened species are secure in botanic garden collections as an insurance policy against loss in the wild. Their work encompasses supporting botanic garden development where this is needed and addressing capacity building needs. They support ex situ conservation for priority species, with a focus on linking ex situ conservation with species conservation in natural habitats and they work with botanic gardens on the development and implementation of habitat restoration and education projects. BGCI uses the IUCN Red List of Threatened Species™ to identify the level of threat to plants. In-depth analyses of the data contained in the IUCN, the International Union for Conservation of Nature, Red List are published periodically (usually at least once every four years). The results from the analysis of the data contained in the 2008 update of the IUCN Red List are published in The 2008 Review of the IUCN Red List of Threatened Species; see www.iucn.org/redlist for further details. -
Polyploidy in the Conifer Genus Juniperus: an Unexpectedly High Rate

One notable example is in the conifer genus Juniperus, where there are already a few reports of polyploids although data are still missing for most species. In this study, we evaluated the extent of polyploidy in Juniperus by conducting the first comprehensive screen across nearly all of the genus. Genome size data from fresh material, together with chromosome counts, were used to demonstrate that genome sizes estimated from dried material could be used as reliable proxies to uncover Edited by: the extent of ploidy diversity across the genus. Our analysis revealed that 16 Juniperus Michael R. McKain, University of Alabama, United States taxa were polyploid, with tetraploids and one hexaploid being reported. Furthermore, by Reviewed by: analyzing the genome size and chromosome data within a phylogenetic framework we Dirk Carl Albach, provide the first evidence of possible lineage-specific polyploidizations within the genus. -
