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 -

As a consequence of relying on non-renewable energy sources and reckless encroachment on natural habitats a lot of plant and animal species have become extinct and more and more species are getting endangered. Thus celebrating biodiversity and solidarity for all life forms, from the tiniest one to the most complex eco-systems, has been in the centre of our attention and operational activities. Keywords: durable development, ecology, endangered species. 1. Introduction Within the massive destruction of forests and forest climate, we witness significant changes, Just as the man has passed from the stage of sometimes radical of the environment. For the animal hunter and collector up to animal raiser and farmer, and plants which have survived through a long period the natural vegetation has increasingly been subject of adaptation, a new difficult era starts again. -

Postharvest Storage and Handling of Ranunculus Asiaticus Dried Tuberous Roots
POSTHARVEST STORAGE AND HANDLING OF RANUNCULUS ASIATICUS DRIED TUBEROUS ROOTS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Christopher Brian Cerveny January 2011 © 2011 Christopher Brian Cerveny POSTHARVEST STORAGE AND HANDLING OF RANUNCULUS ASIATICUS DRIED TUBEROUS ROOTS Christopher B. Cerveny, Ph. D. Cornell University 2011 Ranunculus asiaticus is an ornamental flowering plant with potential to be more widely used by the floriculture industry. Unfortunately, growers are faced with many challenges when producing these plants from their dry tuberous roots following storage; including poor sprouting, non-uniform growth, disease issues upon planting, as well as inconsistent cultural recommendations and lack of proper storage and handling protocols. Several experiments were conducted to determine the influence of temperature and relative humidity during storage on growth and quality of R. asiaticus plants. From our experiments it can be concluded that R. asiaticus tubers store best under low relative humidity and cool temperatures (above freezing). Also important from a storage perspective, unlike other flower bulbs, we show that R. asiaticus tuberous roots are not susceptible to ethylene damage while in the dry state. Prior to planting, tubers should be submerged in room-temperature water at around 20 oC, for 24 h, and then provided a fungicide treatment. We have shown that proper hydration temperature for R. asiaticus tuberous roots is critical for optimal growth. By following the protocol generated from our experiments, many of the production challenges associated with R. asiaticus tuberous roots may be avoided. -

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). -

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. In winter, the snake-bark maples (A. davidii and its relatives) and paper-bark maple (A. -

Email: [email protected] ‘Bring On The Anemones’ I would guess that somewhere or other, all of us have at least one form of Anemone tucked away in our garden, whether we know it or not. In all, there are around 120 species and they vary enormously from tiny rock-garden plants to the tall herbaceous perennials and can flower as early as February or as late as October. In the wild they come from a wide range of habitats mainly in the Northern Hemisphere but a few also come from further South. There is some doubt as to where the name “Anemone” originally comes from. Some believe that is derived from the Greek word “Anemos”, meaning Wind – this eludes to the way that the flowers tend to shake in the gentlest of breezes. -
Floerkea Proserpinacoides Willdenow False Mermaid-Weed
New England Plant Conservation Program Floerkea proserpinacoides Willdenow False Mermaid-weed Conservation and Research Plan for New England Prepared by: William H. Moorhead III Consulting Botanist Litchfield, Connecticut and Elizabeth J. Farnsworth Senior Research Ecologist New England Wild Flower Society Framingham, Massachusetts For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, December 2003 1 SUMMARY Floerkea proserpinacoides Willdenow, false mermaid-weed, is an herbaceous annual and the only member of the Limnanthaceae in New England. The species has a disjunct but widespread range throughout North America, with eastern and western segregates separated by the Great Plains. In the east, it ranges from Nova Scotia south to Louisiana and west to Minnesota and Missouri. In the west, it ranges from British Columbia to California, east to Utah and Colorado. Although regarded as Globally Secure (G5), national ranks of N? in Canada and the United States indicate some uncertainly about its true conservation status in North America. It is listed as rare (S1 or S2) in 20% of the states and provinces in which it occurs. Floerkea is known from only 11 sites total in New England: three historic sites in Vermont (where it is ranked SH), one historic population in Massachusetts (where it is ranked SX), and four extant and three historic localities in Connecticut (where it is ranked S1, Endangered). The Flora Conservanda: New England ranks it as a Division 2 (Regionally Rare) taxon. Floerkea inhabits open or forested floodplains, riverside seeps, and limestone cliffs in New England, and more generally moist alluvial soils, mesic forests, springy woods, and streamside meadows throughout its range. -
