The ecology of the Atlantic white cedar wetlands: a community profile. U.S. Fish Wtldl. Serv. Biol. Rep. 85(7.21). 114 pp. PREFACE This monograph on the ecology of Atlantic white cedar wetlands is one of a series of U.S. Fish and Wildlife Service profiles of important freshwater wetland ecosystems of the United States. The purpose of the profile is to describe the extent, components, functioning, history, and treatment of these wetlands. It is intended to provide a useful reference to relevant scientific information and a synthesis of the available literature. Theworld range of Atlantic white cedar (Chamaecyparis thyoides) is limited to a ribbon of freshwater wetlands within 200 km of the Atlantic and Gulf coasts of the United States, extending from mid-Maine to mid-Florida and Mississippi. Often in inaccessible sites and difficult to traverse, cedar wetlands contain distinctive suites of plant species. Highly valued as commercial timber since the early days of European colonization of the continent, the cedar and its habitat are rapidly disappearing. This profile describes the Atlantic white cedar and the bogs and swamps it dominates or codominates throughout its range, discussing interrelationships with other habitats, putative origins and migration patterns, substrate biogeochemistry, associated plant and animal species (with attention to those that are rare, endangered, or threatened regionally or nationally), and impacts of both natural and anthropogenic distur- bance. Research needs for each area are outlined. Chapters are devoted to the practices and problems of harvest and management, and to an examination of a large preserve recently acquired by the USFWS, the Alligator River National Wildlife Refuge in North Carolina.

    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

  • Chamaecyparis Thyoides)
    Disease Resistance and Aesthetic Evaluation of Atlantic White Cedar (Chamaecyparis thyoides) David R. Sandrock, Michael A. Dirr and Jean Williams-Woodward Horticulture and Plant Pathology - Athens, UGA Since the original cross in 1888, Leyland cypress (xCupressocyparis leylandii) has been planted worldwide. Its rapid upright growth and evergreen foliage make it a popular choice among consumers for windbreaks, hedges, screens, specimens and Christmas trees. However, Leyland cypress is susceptible to at least two fungal pathogens, Seiridium and Botryosphaeria. These pathogens cause canker development which leads to the death of branches and eventually kills the plant. This it is necessary to search for an alternative needle evergreen with similar aesthetic characteristics but greater disease resistance. A possible plant for this role is Atlantic white cedar (Chamaecyparis thyoides). My research consists of two objectives. The first is to screen Atlantic white cedar clones for resistance to Seiridium and Botryosphaeria. The second objective is to select superior taxa of Atlantic white cedar for production based on disease resistance, aesthetic characteristics, growth habits and performance in both field and nursery conditions. The disease screening experiment was initialed in the Fall of 1998. Seiridium, Botryodiplodia and Fusicoccum were isolated from infected branches of Leyland cypress and grown in pure culture. Plants for testing were vegetatively propagated during Fall, 1997. The disease resistance screening experiment consisted of 4 completely randomized blocks of 60 one- gallon plants. Each block contained 10 single-plant replications of 5 clones of Atlantic white cedar and one Leyland cypress. Plants were wounded with a wood rasp at a point on the stem measuring approximately 1 cm in diameter.

  • 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).

  • Dwarf Plants Dwarf Plants Are a Very Diverse and Intriguing Group
    Dwarf Plants Dwarf plants are a very diverse and intriguing group. Prized for their versatility and adaptability, dwarf plants are especially well suited for use in rock gardens, container plantings, and where a small specimen is needed. There are dwarfs that can be used as groundcovers, in full sun to full shade, and for use in formal or informal plantings. The word “dwarf” can mean many things, from having a growth rate of 1” per year or growing to only half the size as what is considered “normal” for that species. The most accepted way to classify a plant as a dwarf is based on its rate of growth. Plants that grow anywhere from 1”-6” per year, or grow to a 1’-6’ size in 10-15 years are considered dwarfs. Dwarfs are great to use in a low maintenance landscape, because they do not require the pruning and care that larger, faster growing shrubs do. Dwarfs make great foundation plants in small areas along a home or driveway, where others shrubs would spread out and cover walkways, block driveway views, etc. There a hundreds of dwarf varieties, many of them being conifers, or needled evergreens. Broadleaf evergreens and deciduous shrubs also have varieties that are considered dwarfs. In addition to a wide range of sizes, dwarfs come in many colors, textures, and shapes. They can be tall and narrow, upright pyramidal, rounded, low- spreading, or weeping. Listed below are many of the most popular dwarf varieties.

    S. Horn Volume 26, no. 4 Southeastern Conifer Quarterly December 2019 American Conifer Society Southeast Region Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, West Virginia From the Southeast Region President We have just finished a successful SER meeting in Gloucester VA. It was a great weekend to meet up with old friends and meet new ones. The weather could not have been any better. A big thank you to Brent Heath and Wayne Galloway for their work to make it great: Brent for offering to host the 2019 meeting in Gloucester and for suggesting venues; Wayne for lining up the vendors and tour gardens. Friday night’s dinner at Brent and Becky’s house was one of the best dinners and locations we have ever had for a meeting! Special thanks, also, to all of our plant donors who made it possible for everyone to bring a special plant home from the meeting, and a big shout out to Valerie and Bill from Piccadilly farm and Nursery for bringing a conifer for everyone who attended the meeting. Currently, we are experiencing our first “Polar Vortex” of the year - about 20 degrees below normal! As soon as it warms up, I plan to head back out to clean up the gardens and do some pruning. I also like to mulch and plant in November and December, since it gives the plants a few extra months to set roots. If you don’t get everything planted before the real winter weather hits, hold potted plants in a protected area since potted plants are affected much more by colder temps than those in the ground.

  • CONIFERS OFTEN USED for BONSAI in NORTH AMERICA We Have Consulted the Plant List and Some Regional Floras to Verify Correct Scientific Names
    CONIFERS OFTEN USED FOR BONSAI IN NORTH AMERICA We have consulted The Plant List and some regional floras to verify correct scientific names. For detailed information on individual conifer species, including photographs, we recommend that you go to conifers.org. Trees are evergreen unless otherwise noted. Species that are native in North America are green. COMMON NAME(s) LATIN NAME (Genus) COMMENTS Firs Abies Firs have flattened needles arranged in more or less flattened rows along opposite sides of twigs. Mature seed cones are upright, appearing somewhat like fat candles on the uppermost tree branches. When the cones are mature, they disintegrate. Firs are widespread inhabitants of cooler areas of the North Temperate Zone. They prefer cool to cold, acid, continually moist soil and high light intensity. These requirements mean that they rarely are successful long-term bonsai subjects. True Cedars Cedrus Depending on which source you consult, there are three to five species in this genus. Atlas Cedar, Cedrus atlantica, is the only species usually used for bonsai, and plants with silvery-bluish needles (‘Glauca’ or “Blue Atlas”) are favored. This species is native in the Atlas Mountains of Morocco and Algeria. False Cypresses Chamaecyparis Chamaecyparis obtusa ‘Nana’, Dwarf Hinoki Cypress, is a selection of Hinoki Cypress which is native to Japan and Taiwan. It is a common bonsai subject. Chamaecyparis thyoides, Atlantic White Cedar, is sometimes used for bonsai. In nature, it grows in acid Southeastern acidic coastal plain bogs. Sawara Cypress, C. pisifera, is a Japanese species occasionally used for bonsai. Members of this genus have flattened, scale-leaves.

  • Palustrine Communities Descriptions
    Classification of the Natural Communities of Massachusetts Palustrine Communities Descriptions Palustrine Communities Descriptions These are wetland natural communities in which the species composition is affected by flooding or saturated soil conditions, and the water table is at or near the surface most of the year. Note: The term “wetland” is not used in the sense of a “jurisdictional wetland,” which has a legal definition. Pitcher Plant, photo by Patricia Swain, NHESP Classification of the Natural Communities of Massachusetts Palustrine Communities Descriptions Acidic Graminoid Fen Community Code: CP2B0B1000 State Rank: S3 Concept: Mixed graminoid/herbaceous acidic peatlands with some groundwater and/or surface water flow but no calcareous seepage. Shrubs occur in clumps but are not dominant throughout. Environmental Setting: Peatlands, commonly called bogs or fens, are wetland communities on peat, which is an accumulation of incompletely decomposed organic material. Bogs and acidic fens are northern communities; Massachusetts is at the southern limit of the geographic range of acidic peatlands, meaning that climatic conditions are marginal and occurrences are patchy. Acidic Graminoid Fens are sedge- and sphagnum-dominated peatlands that are weakly minerotrophic (mineral-rich). Acidic Graminoid Fens typically have some surface water inflow and some groundwater connectivity. Inlets and outlets are usually present, and standing water is present throughout much of the growing season. Peat mats are quaking and often unstable. Vegetation Description: Species of sphagnum moss (Sphagnum spp.) are the most common plants in all acidic peatlands. As with vascular plants, the particular sphagnum species present vary depending on acidity and nutrient availability. Acidic Graminoid Fens have the most diversity of vascular plants of the acidic peatland communities.

Ranney4 Department of Horticultural Science North Carolina State University, Raleigh, NC 27695-7609 Abstract Chamaecyparis are ornamental plants that are used extensively in temperate-zone landscapes worldwide. However, due to their low tolerance to environmental stresses Chamaecyparis often perform poorly in urban landscapes. The objective of this research was to evaluate rootstocks of selected Cupressaceae taxa to determine their adaptability to poor drainage and high temperatures found commonly in urban landscapes. To accomplish this objective, 10 taxa (Chamaecyparis, Platycladus, Thuga spp., and x Cupressocyparis leylandii) were grown in 2.8 liter (#1) black plastic containers with a pinebark:sand (8:1 by vol) medium for 19 weeks in two greenhouses with 9/ 15 hr day/night temperatures of either 22/18C (72/64F) or 30/26C (86/79F).
