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 -

Temporal and Spatial Patterns of Mitochondrial Haplotype And
www.nature.com/scientificreports OPEN Temporal and spatial patterns of mitochondrial haplotype and species distributions in Siberian Received: 16 February 2018 Accepted: 1 November 2018 larches inferred from ancient Published: xx xx xxxx environmental DNA and modeling Laura S. Epp 1, Stefan Kruse1, Nadja J. Kath1,2, Kathleen R. Stoof-Leichsenring1, Ralph Tiedemann2, Luidmila A. Pestryakova3 & Ulrike Herzschuh1,2,4 Changes in species’ distributions are classically projected based on their climate envelopes. For Siberian forests, which have a tremendous signifcance for vegetation-climate feedbacks, this implies future shifts of each of the forest-forming larch (Larix) species to the north-east. However, in addition to abiotic factors, reliable projections must assess the role of historical biogeography and biotic interactions. Here, we use sedimentary ancient DNA and individual-based modelling to investigate the distribution of larch species and mitochondrial haplotypes through space and time across the treeline ecotone on the southern Taymyr peninsula, which at the same time presents a boundary area of two larch species. We fnd spatial and temporal patterns, which suggest that forest density is the most infuential driver determining the precise distribution of species and mitochondrial haplotypes. This suggests a strong infuence of competition on the species’ range shifts. These fndings imply possible climate change outcomes that are directly opposed to projections based purely on climate envelopes. Investigations of such fne-scale processes of biodiversity change through time are possible using paleoenvironmental DNA, which is available much more readily than visible fossils and can provide information at a level of resolution that is not reached in classical palaeoecology. -

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. -
Fluorescent Band Pattern of Chromosomes in Pseudolarix Amabilis, Pinaceae
© 2015 The Japan Mendel Society Cytologia 80(2): 151–157 Fluorescent Band Pattern of Chromosomes in Pseudolarix amabilis, Pinaceae Masahiro Hizume* Faculty of Education, Ehime University, 3 Bunkyo-cho, Matsuyama, Ehime 790–8577, Japan Received October 27, 2014; accepted November 18, 2014 Summary Pseudolarix amabilis belongs to one of three monotypic genera in Pinaceae. This species had 2n=44 chromosomes in somatic cells and its karyotype was composed of four long submetacentric chromosomes and 40 short telocentric chromosomes that varied gradually in length, supporting previous reports by conventional staining. The chromosomes were stained sequentially with the fluorochromes, chromomycin A3 (CMA) and 4′,6-diamidino-2-phenylindole (DAPI). CMA- bands appeared on 12 chromosomes at near terminal region and proximal region. DAPI-bands appeared at centromeric terminal regions of all 40 telocentric chromosomes. The fluorescent-banded karyotype of this species was compared with those of other Pinaceae genera considering taxonomical treatment and molecular phylogenetic analyses reported. On the basis of the fluorescent-banded karyotype, the relationship between Pseudolarix amabilis and other Pinaceae genera was discussed. Key words Chromomycin, Chromosome, DAPI, Fluorescent banding, Pinaceae, Pseudolarix amabilis. In Pinaceae, 11 genera with about 220 species are distinguished and grow mostly in the Northern Hemisphere (Farjon 1990). Most genera are evergreen trees, and only Larix and Pseudolarix are deciduous. Pinus is the largest genus in species number, and Cathaya, Nothotsuga and Pseudolarix are monotypic genera. The taxonomy of Pinaceae with 11 genera is complicated, having some problems in species or variety level. Several higher taxonomic treatments were reported on the base of anatomy and morphology such as resin canal in the vascular cylinder, seed scale, position of mature cones, male strobili in clusters from a single bud, and molecular characters in base sequences of several DNA regions. -

The Latitudinal Distribution of Vegetation Cover in Siberia
BIO Web of Conferences 16, 00047 (2019) https://doi.org/10.1051/bioconf/20191600047 Results and Prospects of Geobotanical Research in Siberia The latitudinal distribution of vegetation cover in Siberia Irina Safronova*, Tatiana Yurkovsksya Komarov Botanical Institute of Russian academy of sciences Professor Popov str., 2, Saint- Petersburg, 197346, Russia Abstract. The latitudinal changes of vegetation cover on the plains of Siberia are observed. In Western Siberia there are 4 zones (tundra and taiga, and forest-steppe and steppe only here), in Central and North-Eastern Siberia – only 2 zones (tundra and taiga).Tundra zone is represented by 4 subzones in Central Siberia; in Western and North-Eastern Siberia – by 3 subzones (there are no polar subzone). All 5 subzones of the taiga zone are distinguished both in Western Siberia and in the Central Siberia, but in the Central Siberia, forests are found in very high latitudes. The feature of the taiga zone of Western Siberia is high paludification. As a result, the vegetation of mires dominates over the zonal vegetation. Zonal West Siberian types are dark coniferous forests. Light coniferous forests predominate in the taiga zone of Central and North-Eastern Siberia. In the forest-steppe zone in Western Siberia forests are small-leaved − birch, aspen-birch (Betula pendula, Populus tremula). The abundance of mires is the feature of this zone, as well as in the taiga. Taiga forests predominate in Siberia. There is tundra vegetation on the Islands of the Arctic Ocean and on narrow strip along its coast; the steppes occupy a small area in the South of the West Siberian lowland. -
COMMON NAME: European Larch SCIENTIFIC NAME: Larix Decidua FAMILY: Pinaceae
COMMON NAME: European larch SCIENTIFIC NAME: Larix decidua FAMILY: Pinaceae Mature size: Height: up to 70 feet. Spread: 25 feet wide or wider at maturity. The top three European larches on Colorado’s Champion Tree Registry are all over 70 feet tall and 45 feet wide. This tree in Colorado: The European larch is an under-utilized conversation piece in Colorado. It functions very effectively in larger landscapes as specimens or groupings. Like the majority of trees, it performs best in acidic, established soils. Once established, the larch requires only moderate moisture, making it an easy fit for most manicured landscapes. The European larch should be transplanted when dormant, as planting during the growing season can result in severe shock. There are no significant diseases of larches present in Colorado and few elsewhere. One precautionary note: although the European larch requires a sunny location, it languishes in heat and should not be sited in areas that will receive reflective heat; it is best in established areas with larger trees (a cooler micro-climate). Hardiness: Zones 3A to 6. Quite cold-hardy and needs to be protected from reflective heat. Growth rate, form, and size: Larches grow quickly in comparison to most other conifers and can gain two feet of height in a growing season. This tree will be gracefully pyramidal with drooping branchlets in its youth, and it becomes more rigid and open as it reaches maturity. Foliage: Sprays of single needles cluster along the branches, emerging as a bright green in spring, turning deeper green and finally yellow or orange in fall. -
