Comparative Study of NZ Pine & Selected SE Asian Species
(FRONT COVER) A COMPARATIVE STUDY OF NEW ZEALAND PINE AND SELECTED SOUTH EAST ASIAN SPECIES (INSIDE FRONT COVER) NEW ZEALAND PINE - A RENEWABLE RESOURCE NZ pine (Pinus radiata D. Don) was introduced to New Zealand (NZ) from the USA about 150 years ago and has gained a dominant position in the New Zealand forest industry - gradually replacing timber from natural forests and establishing a reputation in international trade. The current log production from New Zealand forests (1998) is 17 million m3, of which a very significant proportion (40%) is exported as wood products of some kind. Estimates of future production indicate that by the year 2015 the total forest harvest could be about 35 million m3. NZ pine is therefore likely to be a major source of wood for Asian wood manufacturers. This brochure has been produced to give prospective wood users an appreciation of the most important woodworking characteristics for high value uses. Sponsored by: Wood New Zealand Ltd. Funded by: New Zealand Ministry of Foreign Affairs and Trade Written by: New Zealand Forest Research Institute Ltd. (Front page - First sheet)) NEW ZEALAND PINE - A VERSATILE TIMBER NZ pine (Pinus radiata D.Don) from New Zealand is one of the world’s most versatile softwoods - an ideal material for a wide range of commercial applications. Not only is the supply from sustainable plantations increasing, but the status of the lumber as a high quality resource has been endorsed by a recent comparison with six selected timber species from South East Asia. These species were chosen because they have similar end uses to NZ pine. -
Comparison of Oak and Sugar Maple Distribution and Regeneration in Central Illinois Upland Oak Forests
COmparisON OF OaK AND Sugar MAPLE DistriBUTION AND REGENEratiON IN CEntral ILLINOIS UPLAND OaK FOREsts Peter J. Frey and Scott J. Meiners1 Abstract.—Changes in disturbance frequencies, habitat fragmentation, and other biotic pressures are allowing sugar maple (Acer saccharum) to displace oak (Quercus spp.) in the upland forest understory. The displacement of oaks by sugar maples represents a major management concern throughout the region. We collected seedling microhabitat data from five upland oak forest sites in central Illinois, each differing in age class or silvicultural treatment to determine whether oaks and maples differed in their microhabitat responses to environmental changes. Maples were overall more prevalent in mesic slope and aspect positions. Oaks were associated with lower stand basal area. Both oaks and maples showed significant habitat partitioning, and environmental relationships were consistent across sites. Results suggest that management intensity for oak in upland forests could be based on landscape position. Maple expansion may be reduced by concentrating mechanical treatments in expected areas of maple colonization, while using prescribed fire throughout stands to promote oak regeneration. INTRODUCTION Historically, white oak (Quercus alba) dominated much of the midwestern and eastern U.S. hardwood forests (Abrams and Nowacki 1992, Franklin et al. 1993). Oak is classified as an early successional forest species, and many researchers agree that oak populations were maintained by Native American or lightning-initiated fires (Abrams 2003, Abrams and Nowacki 1992, Hutchinson et al. 2008, Moser et al. 2006, Nowacki and Abrams 2008, Ruffner and Groninger 2006, Shumway et al. 2001). These periodic low to moderate surface fires favored the ecophysiological attributes of oak over those of fire-sensitive, shade-tolerant tree species, thereby continually resetting succession and allowing oaks and other shade-intolerant species to persist in both the canopy and understory (Abrams 2003, Abrams and Nowacki 1992, Crow 1988, Franklin et al. -

Folivory of Vine Maple in an Old-Growth Douglas-Fir-Western Hemlock Forest
3589 David M. Braun, Bi Runcheng, David C. Shaw, and Mark VanScoy, University of Washington, Wind River Canopy Crane Research Facility, 1262 Hemlock Rd., Carson, Washington 98610 Folivory of Vine Maple in an Old-growth Douglas-fir-Western Hemlock Forest Abstract Folivory of vine maple was documented in an old-growth Douglas-fir-western hemlock forest in southwest Washington. Leaf consumption by lepidopteran larvae was estimated with a sample of 450 tagged leaves visited weekly from 7 May to 11 October, the period from bud break to leaf drop. Lepidopteran taxa were identified by handpicking larvae from additional shrubs and rearing to adult. Weekly folivory peaked in May at 1.2%, after which it was 0.2% to 0.7% through mid October. Cumulative seasonal herbivory was 9.9% of leaf area. The lepidopteran folivore guild consisted of at least 22 taxa. Nearly all individuals were represented by eight taxa in the Geometridae, Tortricidae, and Gelechiidae. Few herbivores from other insect orders were ob- served, suggesting that the folivore guild of vine maple is dominated by these polyphagous lepidopterans. Vine maple folivory was a significant component of stand folivory, comparable to — 66% of the folivory of the three main overstory conifers. Because vine maple is a regionally widespread, often dominant understory shrub, it may be a significant influence on forest lepidopteran communities and leaf-based food webs.

Self-Guided Neighborhood Tree Tour Created by Bhopesh Bassi
BELLEVUE NEIGHBORHOOD TREE AMBASSADOR PROGRAM Self-Guided Neighborhood Tree Tour Created by Bhopesh Bassi Neighborhood: Kelsey Creek Park and Farm Starting point: Kelsey Creek Park and Farm parking lot at 410 130th Place SE Summary/Theme: Introduction to plant and animal ecosystem in and around Kelsey Creek Park and Farm. Kelsey Creek Farm Park in Bellevue is a largely overlooked gem. While the park is tucked in the heart of neighborhoods, it feels like an isolated country woods experience. You may have the impression of having traveled back in time as you move from the modern parking lot to a more rural feel as you hike into the forest. Kelsey Creek is Seattle's largest watershed. It runs right down the middle of the park, providing habitat for spawning Salmon, Peamouth and for an abundant population of migratory and resident birds. All lifeform here depends on and contributes to each other and the park is a rich ecosystem. Bring your binoculars along if you also want to watch birds on this tour. BELLEVUE NEIGHBORHOOD TREE AMBASSADOR PROGRAM This tree tour was developed by one of Bellevue’s Neighborhood Tree Ambassador volunteers. The goal of the Neighborhood Tree Ambassador program is to help build community support for trees in Bellevue. Trees are an important part of our community because they provide significant health and environmental benefits. Trees: • Remove pollutants from the air and water • Reduce stress and improve focus • Lower air temperature • Pull greenhouse gases from the atmosphere • Reduce flooding and erosion caused by rain Bellevue has a goal to achieve a 40% tree canopy across the entire city. -
Veneer Guidelines 1
V T INDUSTRIES VENEER GUIDELINES 1 VTWO O D VENEERS PLAN I SLICED NATURAL MAPLE N ATURAL VARIATIONS The word natural brings to mind certain connotations like “beauty”, “warmth” and “purity”. Merriam-Webster defines natural as “occurring in conformity with the ordinary course of nature (the genetically controlled qualities of an organism): not marvelous or supernatural”. Wood is a product of nature, and in some cases, will accentuate and enhance a project design when used in its purest, or natural, state. However, as a product of nature, each wood species has certain intrinsic and industry-acceptable characteristics, which can vary from tree to tree and flitch (half log) to flitch. It is precisely these naturally occurring variations that provide such richness and uniqueness to each project design. Certain wood species such as natural maple and birch can vary widely in color range, which is why in many cases select white is specified so that the sapwood can be accumulated and spliced together to create a consistent color. The photos and information in this brochure are designed to assist you in specifying and receiving the product you envision. When specifying "natural" maple and birch, the veneer will contain unlimited amounts of Sapwood (the light portion of the log) and/or Heartwood (the dark portion of the log) unselected for color. If a light colored veneer is preferred, specify Select White (all Sapwood) maple or birch. If a dark colored veneer is preferred, specify Select Red/Brown (all Heartwood) Note, availability may be limited. 2 VTWO O D VENEERS PLAN I SLICED SELECT WHITE MAPLE HO W TO SPECIFY Natural veneers, such as maple and birch, may contain sapwood/ heartwood combinations, color streaks, spots and color variation from almost white to very dark. -

C, 1951 For sale by the Superintendent of Documents, Washington, D. C. Price 75 cents Preface THOSE who want to be successful in any line of work or business must learn the tricks of the trade one way or another. For most occupations there is a wealth of published information that explains how the job can best be done without taking too many knocks in the hard school of experience. For logging, however, there has been no ade- quate source of information that could be understood and used by the man who actually does the work in the woods. This NORTHEASTERN LOGGERS' HANDBOOK brings to- gether what the young or inexperienced woodsman needs to know about the care and use of logging tools and about the best of the old and new devices and techniques for logging under the conditions existing in the northeastern part of the United States. Emphasis has been given to the matter of workers' safety because the accident rate in logging is much higher than it should be. Sections of the handbook have previously been circulated in a pre- liminary edition. Scores of suggestions have been made to the author by logging operators, equipment manufacturers, and professional forest- ers. -
