Careful, modest, bark stripping has little effect on the health or longevity of trees. (see pages 24 to 35) photograph © Douglas Justice 24 Tree of the Year : Thuja plicata Donn ex D. Don In this year’s Tree of the Year article DOUGLAS JUSTICE writes an account of the western red-cedar or giant arborvitae (tree of life), a species of conifers that, for centuries has been central to the lives of people of the Northwest Coast of America. “In a small clearing in the forest, a young woman is in labour. Two women companions urge her to pull hard on the cedar bark rope tied to a nearby tree. The baby, born onto a newly made cedar bark mat, cries its arrival into the Northwest Coast world. Its cradle of firmly woven cedar root, with a mattress and covering of soft-shredded cedar bark, is ready. The young woman’s husband and his uncle are on the sea in a canoe carved from a single red-cedar log and are using paddles made from knot-free yellow cedar. When they reach the fishing ground that belongs to their family, the men set out a net of cedar bark twine weighted along one edge by stones lashed to it with strong, flexible cedar withes. Cedar wood floats support the net’s upper edge.

  • The Relation of Soil Characteristics to Growth and Distribution of Chamaecyparis Lawsoniana and Thuja,Plicata in Southwestern Oregon
    AN ABSTRACT OF THE THESIS OF DAVID KIMBERLY IMPER for the degree of MASTER OF SCIENCE in BOTANY AND PLANT PATHOLOGY presented on ty,.1/(980 Title: THE RELATION OF SOIL CHARACTERISTICS TO GROWTH AND DISTRIBUTION OF CHAMAECYPARIS LAWSONIANA AND THUJA PLICATA IN SOUTHWESTERN OREGON Redacted for Privacy Abstract approved: lkoLltcT B. Zobel Twelve plots at six sites in southwestern Oregon were studied to determine the degree to which various soil characteristics are related to the occurrence and growth of Chamaecyparis lawsoniana and Thu,la plicata. Soil profiles and vegetation were described in each plot, and measurements were made of insolation, soil and litter temperature, creek and groundwater characteristics, and litter accumulation. Growth was estimated by measurement of age, height, DBH, 10-year basal area increment, and foliage elongation between July, 1979, and January, 1980. In July and September, 1979, and January, 1980, mineral soils from the 0-10 cm level were analyzed for pH, moisture holding capacity, loss-on-ignition, and concentra- tions of nitrate, ammonium and total N. Nitrate and ammonium concentrations were also determined in stream and groundwater. In July and January, fine litter was analyzed for pH, nitrate and ammonium. On each sample date, soils and litter were incubated aerobically for five weeks at 28°C to determine their potentialfor ammonification and nitrification.Ammonium was added to some samples before incubation. Total N concentration was determined for individ- ual foliage samples (collected in September) in most plots; foliage and mineral soil samples were composited for each plot and analyzed for P, Ca, K and Mg concentrations.The various soil and other measurements were related to basal area increment by multiple regression analysis.

  • Native Trees of Georgia
    1 NATIVE TREES OF GEORGIA By G. Norman Bishop Professor of Forestry George Foster Peabody School of Forestry University of Georgia Currently Named Daniel B. Warnell School of Forest Resources University of Georgia GEORGIA FORESTRY COMMISSION Eleventh Printing - 2001 Revised Edition 2 FOREWARD This manual has been prepared in an effort to give to those interested in the trees of Georgia a means by which they may gain a more intimate knowledge of the tree species. Of about 250 species native to the state, only 92 are described here. These were chosen for their commercial importance, distribution over the state or because of some unusual characteristic. Since the manual is intended primarily for the use of the layman, technical terms have been omitted wherever possible; however, the scientific names of the trees and the families to which they belong, have been included. It might be explained that the species are grouped by families, the name of each occurring at the top of the page over the name of the first member of that family. Also, there is included in the text, a subdivision entitled KEY CHARACTERISTICS, the purpose of which is to give the reader, all in one group, the most outstanding features whereby he may more easily recognize the tree. ACKNOWLEDGEMENTS The author wishes to express his appreciation to the Houghton Mifflin Company, publishers of Sargent’s Manual of the Trees of North America, for permission to use the cuts of all trees appearing in this manual; to B. R. Stogsdill for assistance in arranging the material; to W.

  • Coastal Landscaping in Massachusetts Plant List
    Coastal Landscaping in Massachusetts Plant List This PDF document provides additional information to supplement the Massachusetts Office of Coastal Zone Management (CZM) Coastal Landscaping website. The plants listed below are good choices for the rugged coastal conditions of Massachusetts. The Coastal Beach Plant List, Coastal Dune Plant List, and Coastal Bank Plant List give recommended species for each specified location (some species overlap because they thrive in various conditions). Photos and descriptions of selected species can be found on the following pages: • Grasses and Perennials • Shrubs and Groundcovers • Trees CZM recommends using native plants wherever possible. The vast majority of the plants listed below are native (which, for purposes of this fact sheet, means they occur naturally in eastern Massachusetts). Certain non-native species with specific coastal landscaping advantages that are not known to be invasive have also been listed. These plants are labeled “not native,” and their state or country of origin is provided. (See definitions for native plant species and non-native plant species at the end of this fact sheet.) Coastal Beach Plant List Plant List for Sheltered Intertidal Areas Sheltered intertidal areas (between the low-tide and high-tide line) of beach, marsh, and even rocky environments are home to particular plant species that can tolerate extreme fluctuations in water, salinity, and temperature. The following plants are appropriate for these conditions along the Massachusetts coast. Black Grass (Juncus gerardii) native Marsh Elder (Iva frutescens) native Saltmarsh Cordgrass (Spartina alterniflora) native Saltmeadow Cordgrass (Spartina patens) native Sea Lavender (Limonium carolinianum or nashii) native Spike Grass (Distichlis spicata) native Switchgrass (Panicum virgatum) native Plant List for a Dry Beach Dry beach areas are home to plants that can tolerate wind, wind-blown sand, salt spray, and regular interaction with waves and flood waters.

Cover Image: Snow and pendant cones on spruce tree (reproduced with permission of Photos.com). Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Foreword When it comes to reproduction, gymnosperms are deeply weird. Cycads and coni- fers have drawn out reproduction: at least 13 genera take over a year from pollina- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to won- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations.

    Green Spring Gardens 4603 Green Spring Rd ● Alexandria ● VA 22312 Phone: 703-642-5173 ● TTY: 703-803-3354 www.fairfaxcounty.gov/parks/greenspring NON - NATIVE TREES AND LARGE SHRUBS ­ FOR THE WASHINGTON, D.C. AREA ­ Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily.
