COMMON FOREST TREES OF NORTH CAROLINA ( R E V I S E D ) A POCKET MANUAL Produced by the North Carolina Department of Agriculture and Consum er Services North Carolina Forest Service Wib L. Owen, State Forester TWENTIETH EDITION 2012 Foreword Trees may be the oldest and largest living things in nature. They are closely associated with our daily lives, yet most of us know little about them and barely can tell one type of tree from another. Sixteen editions of this handy pocket guide have been printed since John Simcox Holmes, North Carolina's first State Forester, put together the first edition in 1922. Holmes' idea was to provide an easy-to-use reference guide to help people of all ages recognize many of our common forest trees on sight. That goal has not changed. Although the book has changed little, some uses of wood and general information about the trees have. Carriages and wagons, for example, aren't often made from Shagbark hickory (or anything else) anymore, and Loblolly pine now is used for making tremendous amounts of pine plywood, something unheard of in the 1920's. Keeping these changes in mind, we revised Common Forest Trees of North Carolina in 1977 and 1995. -

CITES Appendix II
PC20 Inf. 7 Annex 9 INTRODUCTION TO CITES AND AGARWOOD OVERVIEW Asian Regional Workshop on Agarwood; 22-24 November 2011 By Milena Sosa Schmidt, CITES Secretariat: [email protected] A bit of history Several genera from the family Thymeleaceae are agarwood producing taxa. These are: Aquilaria, Enkleia, Aetoxylon, Gonystylus, Wikstroemia, Gyrinops. They produce different qualities of agarwood from which Aquilaria seems to be the best (see Indonesia report of 2003). From these six genera we have currently three listed on CITES Appendix II. The history of these listings is as follows: THYMELAEACEAE (AQUILARIACEAE) (E) Agarwood, ramin; (S) Madera de Agar, ramin; (F) Bois d'Agar, ramin Aquilaria spp. II 12/01/05 #1CoP13 II/r AE 12/01/05 Excludes Aquilaria malaccensis.

African Mahogany Anegre Birdseye Maple Black Walnut
African Mahogany African Mahogany (Khaya) is a genus of seven species of trees in the mahogany family Meliaceae, native to tropical Africa and Madagascar. All species become big trees 30-35 m tall, rarely 45 m, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet absent; each leaflet is 10-15 cm long abruptly rounded toward the apex but often with an acuminate tip. The leaves can be either deciduous or evergreen depending on the species. The flowers are produced in loose inflorescences, each flower small, with four or five yellowish petals and ten stamens. The timber of Khaya is called African mahogany, the only timber widely accepted as mahogany besides that of the true mahogany, of the genus Swietenia. Khaya senegalensis, also known as the African dry zone mahogany is also used for its non timber parts. In West Africa, Fulani herdsmen prune the tree during the dry season to feed cattle. Anegre Anegre is milled from the Tawa tree (Beilschmiedia tawa) is a New Zealand broadleaf tree common in the central parts of the country. Tawa is often the dominant canopy species in lowland forests in the North Island and north east of the South Island, Individual specimens may grow up to 30 meters or more in height with trunks up to 1.2 meters in diameter, and they have smooth dark bark. The word "tawa" is the Maori name for the tree. One of the few hardwood trees in the country with good timber, the wood of this tree can be used for attractive and resilient floor boarding. -
Seasoning and Handling of Ramin1
U. S. DEPARTMENT OF AGRICULTURE FOREST SERVICE FOREST PRODUCTS LABORATORY MADISON,WIS. In Cooperation with the University of Wisconsin U. S. FOREST SERVICE RESEARCH NOTE FPL- 0172 SEPTEMBER 1967 SEASONING AND HANDLING OF RAMIN1 By JOHN M. McMILLEN, Technologist Forest Products Laboratory, Forest Service U.S. Department of Agriculture Abstract One of the imported woods that is finding increasing use for specific purposes is ramin (Gonystylus spp.). It originates in the Southwest Pacific and has seasoning properties somewhat like oak. Many importers, custom dryers, and users are not aware of the special seasoning and handling requirements of this wood. As a result, some firms have experienced heavy losses. This note brings together suggestions that should greatly reduce or eliminate these losses. Ramin--Production and Properties Ramin (pronounced ray-min) is the common name used in the United States for wood from Gonystylus spp., principally G. bancanus growing in Sarawak, Malaysia. Another common name used in Malaya is melawis. The trees grow 1 Partly based on information from experienced importers, custom dryers, and users of ramin. in fresh water swamp forests and have straight, clean boles averaging 60 feet long and 2 feet in diameter near the base. Principal sources are the river valleys of Sarawak and the west coast of Malaya. In the Philippines, G. macrophyllus is common in the primary forests. An undetermined species is fairly comon in the Solomon Islands, Ramin is an attractive, high-class utility hardwood having about the same weight as sycamore or paper birch. Both the sapwood and the heartwood are white to pale straw in color. -
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607)
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607) by Nancy Ross Preface Since it was published in 1984, Tropical Timbers of the World has proven to be an extremely valuable reference to the properties and uses of tropical woods. It has been particularly valuable for the selection of species for specific products and as a reference for properties information that is important to effective pro- cessing and utilization of several hundred of the most commercially important tropical wood timbers. If a user of the book has only a common or trade name for a species and wishes to know its properties, the user must use the index of common names beginning on page 451. However, most tropical timbers have numerous common or trade names, depending upon the major region or local area of growth; furthermore, different species may be know by the same common name. Herein lies a minor weakness in Tropical Timbers of the World. The index generally contains only the one or two most frequently used common or trade names. If the common name known to the user is not one of those listed in the index, finding the species in the text is impossible other than by searching the book page by page. This process is too laborious to be practical because some species have 20 or more common names. This supplement provides a complete index of common or trade names. This index will prevent a user from erroneously concluding that the book does not contain a specific species because the common name known to the user does not happen to be in the existing index. -

This document has been submitted by Canada, on behalf of Namibia and Canada as joint leads for the Standing Committee on the issue of Annotations.* Background 2. At the 17th meeting, (CoP17; Johannesburg, 2016) the Conference of the Parties adopted Decision 16.162 (Rev. CoP17) which directs the Standing Committee to re-establish the working group on annotations, in close collaboration with the Animals and Plants Committees. At its 68th meeting (Johannesburg, 2016), the Standing Committee agreed that Canada and Namibia would lead on the issue of annotations. 4. After discussion with the Chair of the Standing Committee in February 2017 and consultation between Canada and Namibia, it was agreed to engage members of the previous Standing Committee Annotations Working Group in advance of the 69th meeting of the Standing Committee (November 2017; SC69), to continue discussions relating to the work included in the working group terms of reference contained in Decision 16.162 (Rev. CoP17). In April 2017, in response to concerns raised by the Secretariat in advance of CoP17 regarding a lack of regional diversity in the working group in its discussions during the CoP16/CoP17 intersessional period, the Chair of the CITES Plants Committee confirmed that ten members or alternate members of the Plants Committee had expressed interest in participating in the Standing Committee’s work on annotations. -
Development of Nuclear SNP Markers for Mahogany (Swietenia Spp.)

The three species are listed as either vulnerable or endangered by IUCN and are included on Appendix II of CITES, yet illegal exploitation continues. Here, we used restriction associated DNA sequencing to develop a new set of 120 SNP markers for Swietenia sp., suitable for MassARRAY®iPLEX™ genotyping. These markers can be used for population genetic studies and timber tracking purposes.

TREE RING CHARACTERISTICS OF 30-YEAR-OLD SWIETENIA MACROPHYLLA PLANTATION TREES Cheng-Jung Lin* Associate Researcher Department of Forest Utilization Taiwan Forestry Research Institute Taipei, Taiwan E-mail: [email protected] Chih-Hsin Chung Assistant Researcher Department of Forest Management Taiwan Forestry Research Institute Taipei, Taiwan E-mail: [email protected] Chih-Lung Cho Professor Department of Natural Resources National I-Lan University Ilan, Taiwan E-mail: [email protected] Te-Hsin Yang Assistant Professor Department of Forestry College of Nature Resource and Agriculture National Chung Hsing University Taichung, Taiwan E-mail: [email protected] (Received October 2011) Abstract. Ring characteristics of mahogany (Swietenia macrophylla K.) plantation trees grown in Taiwan were explored. Significant differences in average ring width (RW) and ring density (RD) occurred among three tree-diameter classes and three radial stages of ring numbers. RW in the radial direction decreased from the pith outward to the bark and followed a distinctive three-stage variation pattern (juvenile, transition, and mature zones). RD in the radial direction increased slowly from the pith outward to the bark. Wider tree rings and lower density are associated with juvenile wood close to the pith, whereas narrower tree rings and higher density are typical for mature wood outward toward the bark. RD in overtopped trees was higher than that in dominant trees. However, RW in dominant trees was wider than that in intermediate and overtopped trees. Earlywood density, latewood density, maximum density, and minimum density were the most important factors determining overall RD. There was a weak relationship between RW and RD, indicating that it is unlikely for growth rates of mahogany plantation trees to have a significant impact on wood density. -
