Thuja Plicata Has Many Traditional Uses, from the Manufacture of Rope to Waterproof Hats, Nappies and Other Kinds of Clothing
photograph © Daniel Mosquin Culturally modified tree. The bark of Thuja plicata has many traditional uses, from the manufacture of rope to waterproof hats, nappies and other kinds of clothing. 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. -

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. -

Moreover, there is a lot of contradictory information in the literature about oriental arborvitae, especially in terms of microscopic structure. Therefore, the sapwood (S) and heartwood (H) of Platycladus orientalis (L.) Franco from Central Europe were subjected to examinations. The presence of helical thickenings was found in earlywood tracheids (E). Latewood tracheids (L) were characterized by a similar thickness of radial and tangential walls and a similar diameter in the tangential direction in the sapwood and heartwood zones. In the case of earlywood tracheids, such a similarity was found only in the thickness of the tangential walls. The volume swelling (VS) of sapwood and heartwood after reaching maximum moisture content (MMC) was 12.8% (±0.5%) and 11.2% (±0.5%), respectively. The average velocity of ultrasonic Citation: Laskowska, A.; Majewska, waves along the fibers (υ) for a frequency of 40 kHz was about 6% lower in the heartwood zone K.; Kozakiewicz, P.; Mami´nski,M.; than in the sapwood zone.

(May 2007) Geoffrey Carlile Denny, B.S., Texas A&M University; M.A., The University of Texas Chair of Advisory Committee: Dr. Michael A. Arnold Taxodium distichum (L.) Rich. is a widely adaptable, long-lived tree species for landscape use. It is tolerant of substantial soil salt levels, but tends to defoliate in periods of extended or severe drought, when leaves come into contact with salty irrigation water, and tends to develop chlorosis on high pH soils. The purpose of this research was to identify provenances which may yield genotypes tolerant of these stresses. The appropriate name for baldcypress is Taxodium distichum (L.) Rich. var. distichum, for pondcypress is T. distichum var. imbricarium (Nutt.) Croom, and for Montezuma cypress is T. distichum var. -

Used extensively in ornamental plantings, there are numerous cultivars available for a range of size, form and foliage color. Many can be recognized by their distinctive scale-like foliage and flattened branchlets. Two popular species, T. occidentalis and T. plicata, are native to North America. Insect pests include leafminers, spider mites and bagworms. Leaf and tip blights may affect arbor- vitae in forest, landscape and nursery settings. INSECTS Arborvitae Leafminer, Argyresthia thuiella, is a native insect pest of Thuja spp. While there are several species of leafminers that attack arborvitae in the United States, A. thuiella is the most common. Its range includes New England and eastern Canada, south to the Mid-Atlantic and west to Missouri (5). Arborvitae is the only known host (6). Heavy feeding in fall and early spring causes yellow foliage that later turns brown. Premature leaf drop may follow. Plants can survive heavy defoliation, but their aesthetic appeal is greatly diminished. Re searchers at The Morton Arboretum report significant differences in relative susceptibility to feeding by arborvitae leafminer for several Thuja species and cultivars.

Long-Term Peat Accumulation in Temperate Forested Peatlands (Thuja Occidentalis Swamps) in the Great Lakes Region of North America
Long-term peat accumulation in temperate forested peatlands (Thuja occidentalis swamps) in the Great Lakes region of North America C.A. Ott and R.A. Chimner School of Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI, USA _______________________________________________________________________________________ SUMMARY Peatlands are being mapped globally because they are one of the largest pools of terrestrial carbon (C). Most inventories of C have been conducted in northern Sphagnum dominated peatlands or tropical peatlands. Northern white-cedar (cedar, Thuja occidentalis L.) peatlands are amongst the most common peatland types in the Great Lakes Region of North America, yet there is no information on their C pool sizes or rates of C accumulation. Therefore, the main objectives of this study were to determine: 1) the ages of cedar peatlands; 2) the amount of C stored in the peat profile; and 3) the apparent long-term rate of C accumulation. We sampled 14 cedar peatland sites across northern Minnesota and the Upper Peninsula of Michigan, USA. Cedar peat was found to be derived mostly from wood and to have an average thickness of 1.12 m (range 0.3–3.25 m). Basal dates indicated that cedar peatlands were initiated between 1,970 and 8,590 years ago, and they appear to have been continuously occupied by cedar. Long-term apparent rates of C accumulation (LARCA) ranged from a low of 6.4 g C m-2 yr-1 to a high of 39.7 g C m-2 yr-1, averaging 17.5 g C m-2 yr-1. Cedar peatlands tend to be shallower than Sphagnum peatlands in the region but, due to their higher bulk density (average 0.16 g cm-3), they contain high amounts of C with our sites averaging ~80 kg C m-2.
