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 -

Seiridium Canker of Cypress Trees in Arizona Jeff Schalau
ARIZONA COOPERATIVE E TENSION AZ1557 January 2012 Seiridium Canker of Cypress Trees in Arizona Jeff Schalau Introduction Leyland cypress (x Cupressocyparis leylandii) is a fast- growing evergreen that has been widely planted as a landscape specimen and along boundaries to create windbreaks or privacy screening in Arizona. The presence of Seiridium canker was confirmed in Prescott, Arizona in July 2011 and it is suspected that the disease occurs in other areas of the state. Seiridium canker was first identified in California’s San Joaquin Valley in 1928. Today, it can be found in Europe, Asia, New Zealand, Australia, South America and Africa on plants in the cypress family (Cupressaceae). Leyland cypress, Monterey cypress, (Cupressus macrocarpa) and Italian cypress (C. sempervirens) are highly susceptible and can be severely impacted by this disease. Since Leyland and Italian cypress have been widely planted in Arizona, it is imperative that Seiridium canker management strategies be applied and suitable resistant tree species be recommended for planting in the future. The Pathogen Seiridium canker is known to be caused by three different fungal species: Seiridium cardinale, S. cupressi and S. unicorne. S. cardinale is the most damaging of the three species and is SCHALAU found in California. S. unicorne and S. cupressi are found in the southeastern United States where the primary host is JEFF Leyland cypress. All three species produce asexual fruiting Figure 1. Leyland cypress tree with dead branch (upper left) and main leader bodies (acervuli) in cankers. The acervuli produce spores caused by Seiridium canker. (conidia) which spread by water, human activity (pruning and transport of infected plant material), and potentially insects, birds and animals to neighboring trees where new Symptoms and Signs infections can occur. -

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). -
Tennessee Christmas Tree Production Manual
PB 1854 Tennessee Christmas Tree Production Manual 1 Tennessee Christmas Tree Production Manual Contributing Authors Alan B. Galloway Area Farm Management Specialist [email protected] Megan Bruch Leffew Marketing Specialist [email protected] Dr. David Mercker Extension Forestry Specialist [email protected] Foreword The authors are indebted to the author of the original Production of Christmas Trees in Tennessee (Bulletin 641, 1984) manual by Dr. Eyvind Thor. His efforts in promoting and educating growers about Christmas tree production in Tennessee led to the success of many farms and helped the industry expand. This publication builds on the base of information from the original manual. The authors appreciate the encouragement, input and guidance from the members of the Tennessee Christmas Tree Growers Association with a special thank you to Joe Steiner who provided his farm schedule as a guide for Chapter 6. The development and printing of this manual were made possible in part by a USDA specialty crop block grant administered through the Tennessee Department of Agriculture. The authors thank the peer review team of Dr. Margarita Velandia, Dr. Wayne Clatterbuck and Kevin Ferguson for their keen eyes and great suggestions. While this manual is directed more toward new or potential choose-and-cut growers, it should provide useful information for growers of all experience levels and farm sizes. Parts of the information presented will become outdated. It is recommended that prospective growers seek additional information from their local University of Tennessee Extension office and from other Christmas tree growers. 2 Tennessee Christmas Tree Production Manual Contents Chapter 1: Beginning the Planning ............................................................................................... -
Chamaecyparis Lawsoniana in Europe: Distribution, Habitat, Usage and Threats
Chamaecyparis lawsoniana Chamaecyparis lawsoniana in Europe: distribution, habitat, usage and threats T. Houston Durrant, G. Caudullo The conifer Lawson cypress (Chamaecyparis lawsoniana (A. Murray) Parl.) is native to a small area in North America. Variable in form, there are over 200 cultivars selected for horticultural purposes. It has been planted in many countries in Europe, usually as an ornamental, although the timber is also of good quality. It has been severely affected in its native range by root rot disease, and this has now spread to the European population. Chamaecyparis lawsoniana (A. Murray) Parl., known as Lawson cypress, or Port Orford cedar in the United States, is a Frequency large conifer native to North America. It belongs to the family < 25% 25% - 50% Cupressaceae, and is sometimes referred to as a “false-cypress” 50% - 75% to distinguish it from other cypresses in the family. It is long- > 75% lived (more than 600 years) and can reach heights of up to 50 m (exceptionally up to 70 m in its native range) and a diameter exceeding 2 m1, 2. The tree is narrowly columnar with slender, down-curving branches; frequently with forked stems. The bark is silvery-brown, becoming furrowed and very thick with age giving mature trees good fire resistance2, 3. The wood is highly aromatic with a distinctive ginger-like odour, as is the foliage which has a parsley-like scent when crushed3, 4. The evergreen scale-like leaves are around 2-3 mm long5. Abundant, round pea-sized cones ripen in autumn with seed dispersal occurring immediately after and continuing until the following spring6. -
