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 -
Red-Breasted Nuthatch and Golden-Crowned Kinglet
Red-breasted Nuthatch and Golden-crowned Kinglet: The First Nests for South Carolina and Other Chattooga Records Frank Renfrow 611 South O’Fallon Avenue, Bellevue, KY 41073 [email protected] Introduction The Chattooga Recreation Area (referred to as CRA for purposes of this article), located adjacent to the Walhalla National Fish Hatchery (780 m) within Sumter National Forest, Oconee Co., South Carolina, has long been noted as a unique natural area within the state. The picnic area in particular, situated along the East Fork of the Chattooga River, contains an old-growth stand of White Pine (Pinus strobus) and Canada Hemlock (Tsuga canadensis) with state records for both species as well as an impressive understory of Mountain Laurel (Kalmia latifolia) and Great Laurel (Rhododendron maximum) (Gaddy 2000). Nesting birds at CRA not found outside of the northwestern corner of the state include Black-throated Blue Warbler (Dendroica caerulescens) and Dark-eyed Junco (Junco hyemalis). Breeding evidence of two other species of northern affinities, Red-breasted Nuthatch (Sitta canadensis) and Golden-crowned Kinglet (Regulus satrapa) has previously been documented at this location (Post and Gauthreaux 1989, Oberle and Forsythe 1995). However, nest records of these two species have not been documented prior to this study. The summer occurrence of two other northern species on the South Carolina side of the Chattooga River, Brown Creeper (Certhia americana) and Winter Wren (Troglodytes troglodytes) has not been previously recorded. Only a few summer records of the Blackburnian Warbler (Dendroica fusca) have been noted for the state. Extensive field observations were made by the author in the Chattooga River area of Georgia and South Carolina during the breeding seasons of 2000, 2002 and 2003 in order to verify breeding of bird species of northern affinities. -
Estimating Numbers of Embryonic Lethals in Conifers
Heredity 69(1992)308—314 Received 26 November 1991 OThe Genetical Society of Great Britain Estimating numbers of embryonic lethals in conifers OUTI SAVOLAINEN, KATRI KARKKAINEN & HELMI KUITTINEN* Department of Genetics, University of Oulu, Oulu, Fin/and and *Department of Genetics, University of Helsinki, He/sink,, Fin/and Conifershave recessive lethal genes that eliminate most selfed embryos during seed development. It has been estimated that Scots pine has, on average, nine recessive lethals which act during seed development. Such high numbers are not consistent with the level of outcrossing, about 0.9—0.95, which has been observed in natural populations. Correcting for environmental mortality or using partial selfings provides significantly lower estimates of lethals. A similar discordance with numbers of lethals and observed outcrossing rates is true for other species. Keywords:embryoniclethals, inbreeding depression, outcrossing, Pinus sylvestris, Picea omorika. Introduction Reproduction system of conifers Conifershave no self-incompatibility mechanisms but Theproportion of self-pollination in conifers is early-acting inbreeding depression eliminates selfed variable. Sarvas (1962) suggested an average of 26 per embryos before seed maturation (Sarvas, 1962; cent for Pinus sylvestris, while Koski (1970) estimated Hagman & Mikkola, 1963). A genetic model for this values of self-fertilization around 10 per cent.

SILVER BIRCH (BETULA PENDULA) at 200-230°C Raimo Alkn Risto Kotilainen
THERMAL BEHAVIOR OF SCOTS PINE (PINUS SYLVESTRIS) AND SILVER BIRCH (BETULA PENDULA) AT 200-230°C Postgraduate Student Raimo Alkn Professor and Risto Kotilainen Postgraduate Student Department of Chemistry, Laboratory of Applied Chemistry University of Jyvaskyla, PO. Box 35, FIN-40351 Jyvaskyla, Finland (Received April 1998) ABSTRACT Scots pine (Pinus sylvestris) and silver birch (Betuln pendula) were heated for 4-8 h in a steam atmosphere at low temperatures (200-230°C). The birch feedstock decomposed slightly more exten- sively (6.4-10.2 and 13515.2% of the initial DS at 200°C and 225"C, respectively) than the pine feedstock (5.7-7.0 and 11.1-15.2% at 205°C and 230°C. respectively). The results indicated that the differences in mass loss between these feedstocks were due to mainly the fact that carbohydrates (cellulose and hemicelluloses) were more amenable to various degradation reactions than lignin in intact wood. The degradation reactions were also monitored in both cases by determining changes in the elemental composition of the heat-treated products. Keywords: Heat treatment, carbohydrates, lignin, extractives, Pinus sylvestris, Betula pendula.

There are some differences between lodgepole pine and Scots pine (Pinus sylvestris) forests which could affect bird assemblages, for example differences in canopy density and ground vegetation. Birds were surveyed in 14 localities in northern Sweden, each characterized by one middle-aged stand of lodgepole pine next to a stand of Scots pine. The two paired stands in each locality were planted by the forestry company SCA at the same time and in similar environment to evaluate the potential of lodgepole pine in Sweden. In those 14 localities, one to three point count stations were established in both the lodgepole pine and the Scots pine stand, depending on the size of the area. -
Ruby-Crowned Kinglet Regulus Calendula the Ruby-Crowned Kinglet Is a Winter Visitor, Com- Monest in Riparian and Oak Woodland
Kinglets — Family Regulidae 427 Ruby-crowned Kinglet Regulus calendula The Ruby-crowned Kinglet is a winter visitor, com- monest in riparian and oak woodland. It uses a wide variety of other habitats too, from urban eucalyptus trees to pines and firs in the mountains to desert oases. The Ruby-crowned Kinglet is San Diego County’s leading practitioner of hover-gleaning: hovering momentarily at a leaf to glean minute insects. A northward contraction of the species’ breeding range is not yet reflected in a decline in its winter numbers.

Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like. Pm-1383 | May 1996 Single needles, flattened with rounded tips Pseudotsuga menziesii Douglas Fir Needles occur on raised pegs; 3/4-11/4 inches in length; cones have 3-pointed bracts between the cone scales.

Ruby-Crowned Kinglet Regulus Calendula
Ruby-crowned Kinglet Regulus calendula Folk Name: Je-dit Status: Winter Resident Abundance: Fairly Common to Common Habitat: Coniferous forests or mixed hardwood forests The Ruby-crowned Kinglet averages half an inch larger than its golden-crowned cousin. It is olive green above and buffy below. It has no eye stripe, rather it has a white eye-ring. It has two white wing bars and one black. The female lacks a colorful crown, but the male has a bright ruby-red crown that is especially visible when the bird is agitated. When the male is calm, the red crown can be quite difficult to see. Rudy-crowned Kinglets are often heard before they are seen. Their call is a sharpje-dit, je-dit. In this region, Ruby-crowned Kinglets are a bit less common than Golden-crowned Kinglets during the winter.

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. -
