Dalbergia Proposal Guatemala (Rev.2)
CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II A. Proposal Inclusion of the genus Dalbergia in CITES Appendix II with exception to the species included in Appendix I. The UNEP-WCMC assessed the Dalbergia species of Latin America and concluded: “… all populations of Dalbergia spp. from South and Central America appear to meet the criteria for listing in CITES Appendix II” (UNEP-WCMC, 2015). Including the whole genus in Appendix II will be essential for the control of international trade by eliminating the arduous task of enforcement and customs officers of differentiating between the hundreds of Dalbergia species listed and not listed in CITES. The inclusion will help ensure that legal trade does not become a direct cause of the extinction of these highly threatened species and will help curb illegal trade. Considering that CITES Appendix II must include all species, which although not necessarily now threatened with extinction may become so unless trade in specimens of such species is subject to strict regulation in order to avoid utilization incompatible with their survival, it is important to include the genus Dalbergia in CITES Appendix II. a) Resolution Conf. 9.24, Annex 2 a, Criterion A - ”It is known, or can be inferred or projected, that the regulation of trade in the species is necessary to avoid it becoming eligible for inclusion in Appendix I in the near future”. b) Resolution Conf. 9.24, Annex 2 a, Criterion B - ”It is known, or can be inferred or projected, that regulation of trade in the species is required to ensure that the harvest of specimens from the wild is not reducing the wild population to a level at which its survival might be threatened by continued harvesting or other influences”. -
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. -

What can I say, just keep shoveling! So much for a mild win- ter. As most of you are aware, the February meeting was canceled because of weath- er. If you didn't get the email notice, I apologize. It may have gone out on an older mailing list. So that being a situa- tion, if you need to send info out to club members, make sure you have the latest list. You can get it from Randy. If you have bowls yet for "Feed My People " please contact me at [email protected] and I will get them from you. Each of you who are signed up to do a demo at a club meeting, please just move your demo forward one month. If that can't work, let me know. We are always looking for new ideas for demos for club meetings. If you would like a demonstration on a given area of wood turning, let me know and we will try to get in in the schedule. For those of you who like to turn natural edge bowls, now is the time to cut the trees before the sap starts to flow. The bark is less likely to loosen. Obviously because on no meeting this month our letter will be somewhat shorter. I give Tom credit for his creativity in making it informative, Thanks Tom ! Well again as Bugs Bunny sez, "That's all folks" Prez Duane. -

Most are seen 8 to 12 feet tall with a beautiful array of multiple trunks and a rounded canopy much like that of a mature crape-myrtle. The one to two-inch-long, leathery, dark green leaves are joined at many times throughout the year by the production of large clusters of bluish purple flowers, the old flowers fading to a light silvery-blue and creating a shimmering haze over the rounded canopy. These flowers are followed by small, heart-shaped, yellow orange berries, appearing on the tree at the same time as the bluish purple flowers and creating a lovely sight.

While a number of tree species had been brought under CITES regulation over the previous decades1, COP-17 saw a marked expansion of CITES timber species listings. The Parties at COP-17 listed the entire Dalbergia genus (some 250 species, including many of the most prized rosewoods), Pterocarpus erinaceous (kosso, a highly-exploited rosewood species from West Africa) and three Guibourtia species (bubinga, another African rosewood) to CITES Appendix II.2 The new listings entered into force on January 2, 2017. -

Email: [email protected] Abstract Dalbergia melanoxylon is an economically and ecologically important timber yielding tree species. It is propagated through seeds, but is not successful because of poor seed germination that limits its multiplication. Therefore, the objective of this study was to develop efficient micropropagation protocol for this species. Cotyledonary nodes were used as explants. The highest (85.33%) explants initiated shoots on Murashige and Skoog (MS) medium containing 2.0 mg/l 6-benzyl amino purine (BAP) and 1.0 mg/l -Naphthaleneα acetic acid (NAA) of the culture revealed greatest shoot multiplication (6.12 ± 0.13) from nodal segments. The shoots rooted best (92%) on MS medium containing 1.0 mg/l NAA with 5.89 ± 0.47 roots per microshoot. Plantlets were planted in pots containing sterilized forest soil and sand mixture (1:1) and acclimatized in greenhouse. After four weeks of acclimatization in greenhouse, 84.6 % of plants survived. This protocol could be useful for large-scale multiplication and conservation of this ecologically and economically important multipurpose tree.

Is Guaiacum Sanctum Effective Against Arthritis? an Ethnobotany
Is Guaiacum sanctum Effective Against Arthritis? An Ethnobotany Case by Eric Ribbens, Barbra Burdett, and Angela Green Department of Biological Science Western Illinois University Part I—Anecdotal Evidence Dr. Beth Tonoany is a tropical population ecologist who has been studying an unusual tree, Guaiacum sanctum, which once grew throughout the dry tropical forests of Central America as well as on some of the Caribbean islands. Guaiacum sanctum produces a wood called lignum vitae, and is known in Costa Rica and other Spanish-speaking countries as guayacan reál. The wood is extremely heavy because it contains extensive deposits of resin (Howes, 1949) and it will sink if placed in water (Wilson and Eisner, 1968). During World War I and II it was extensively harvested for use in the ship-building industry because the wood, which does not split easily, is self- lubricating due to its high resin content. The wood is very durable, and was in high demand for constructing bearing sleeves to support ship propellor Figure 1: Seeds of shafts (Scurlock, 1987). It has also been used for making railroad ties Guaiacum sanctum (Woods, 1951). Dr. Tonoany has been studying one of the last remaining populations of lignum vitae in the Palo Verde Nature Preserve in northwestern Costa Rica. Probably fewer than 100 trees remain in Costa Rica, most in the Palo Verde Nature Preserve. Her research has included tracking seedlings and saplings, locating and measuring adult trees, and interviewing some of the local Ticos to learn about the tree’s past history in Costa Rica. The tree, while rare now due to the dramatic conversion of tropical deciduous forest in Costa Rica into pasturelands and to selective logging of the tree for its valuable wood, was once more common, and many of the older Ticos remember that the saplings were used to make cattle switches because of the strong flexible wood in the saplings. -

Montserrat Geothermal Drilling 2015 EIA

The assessment includes a baseline for each variable followed by a discussion on impacts on the physical, natural, human and social environments. However, since the drilling is taking place in an elevated area on St. George’s Hill, in Zone V, which was evacuated after the 1995 eruption and has remained a restricted area, there are limited human and environmental impacts expected from the drilling of MON-3. Most of the vegetation is secondary forest and scrub. No sensitive or endangered flora and fauna are at risk. The hillside vegetation was once covered in ash. The Belham Valley forms a low lying area north of St. George’s Hill. This has been heavily inundated with volcano muds left over from lahars. Importantly, the drill site was selected not only for its geothermal potential, but also because it’s elevated provides protection from lava flows which may arise from future eruptions. -

Effective Cutting Type in the Rooting of Dalbergia Melanoxylon in Tanzania
International Journal of AgriScience Vol. 4(4):256-259, April 2014 www.inacj.com ISSN: 2228-6322© International Academic Journals Effective Cutting type in the Rooting of Dalbergia melanoxylon in Tanzania Washa B.* Washa Mkwawa University College of Education, P.O. Box. Private Bag Iringa Tanzania. *Author for corespondence (email: [email protected]). 0752 356 709 Received February 2014; accepted in revised form March 2014 ABSTRACT A study was conducted to assess the effective type of cutting in rooting of Dalbergia melanoxylon, a woody and non-domesticated species but of highly valued wood and wide spread in tropical Africa and overharvested. Softwood, semi-hardwood, hardwood and root cuttings were excised in wet season and dry season 2010. Soil rhizosphere of the sampled plants was used as potting media in a non-mist propagator in a split plot design. Rooting test was monitored for 3 months during the two seasons. Parameters recorded during the experiment included the proportion of cuttings that rooted, callused, sprouted and the number of roots per cutting. The data were analyzed according to objectives and variables of the study using SPSS software. Results from each experiment were analyzed separately using ANOVA in SPSS software, while differences between treatment means were compared using Duncan Multiple Range Test. Results indicated 100% rooting softwood cuttings, 37% in root cuttings and none of the semi-hardwood and hardwood cuttings rooted. Softwood cuttings of less than 15gms outperformed others in rooting of D. melanoxylon followed by root cuttings. Plant propagators are advised to use softwood cuttings.
