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.

Regarding monitoring of wildlife farms and related trade 6. Public awareness and outreach campaigns 3. The Standing Committee also recommended that Lao PDR submit an adequate implementation plan with timelines and indicators for complete implementation of recommendations 2-6 by 31 December 2017 and provide a report to the Secretariat on implementation of recommendations 2-6 by 30 June 2018. Finally, the Standing Committee decided that the Secretariat should publish a Notification to the Parties recommending a suspension of trade with Lao PDR if it determined that the adequate implementation plan with timelines and indicators had not been provided by 31 December 2017 or if implementation of recommendations 2-6 had not been substantially achieved by 30 June 2018.

Botanically it has been identified as Dalbergia volubilis Roxb. This research article overcomes the lacuna and explores the anatomical, Deoxyribonucleic acid (DNA) barcoding and preliminary phytochemical analysis including High Performance Thin Layer Chromatography (HPTLC). Methods: After proper authentication, leaves were exposed to macroscopy, microscopy and micrometric analysis and physicochemical, qualitative, quantitative and HPTLC study as per of Ayurvedic Pharmacopoeia of India (API). DNA barcoding of the fresh tender leaves samples were carried out following standard methods. Results: Macroscopically leaves are compound, unipinnate, imparipinnate, rachis base pulvinus, leaflets 11-13. Microscopy of T. S. of rachis resembles anatomical structure of stem. Schematic outline of T. S. of petiolule is circular in shape with single layer epidermis is followed by ground tissue and centrally located vascular bundle. Schematic outline of T. S. of leaflet is bulged in the center and the extending arms of lamina are linear. Surface study reveals stomatal index to be 33.33. The genetic barcoding confirms the species D.

  • SITE INDEX of SIAMESE ROSEWOOD (Dalbergia Cochinchinensis Pierre) in PLANTATIONS of THAILAND
    SITE INDEX OF SIAMESE ROSEWOOD (Dalbergia cochinchinensis Pierre) IN PLANTATIONS OF THAILAND TAENGMOO PHUNCHAISRI1, CHONGRAK WACHRINRAT1*, PONTHEP MEUNPONG1, SUWAN TANGMITCHAROEN2 AND NAWAPHONG KUASAKUN1 1 Department of Silviculture Faculty of Forestry Kasetsart University, Bangkok 10900, Thailand 2 Forest Research and Development Bureau, Royal Forest Department, Bangkok 10900, Thailand *Corresponding author, e-mail: [email protected] ABSTRACT Currently, decreased productivity of Siamese rosewood (Dalbergia cochinchinensis Pierre) is a problem due to illegal logging and the guidelines to manage this prevention being may be insufficient. Forest plantations should be promoted to achieve sustainable wood production for this species. Site index (SI) is a measure that can be used to predict forest productivity to identify appropriate sites for planting Siamese rosewood. The objective of the current study was to predict the SI for Siamese rosewood in Thailand. A sample of 78 temporary plots at 26 sites in 16 provinces of Thailand was selected to construct a site index curve with a base age of 30 yr. The results showed that the mean age of Siamese rosewood was 28 yr (between 13 and 55 yr), the mean diameter at breast height (DBH) was 20.03 cm (between 7.99 and 33.80 cm), and the mean dominant height was 20.79 m (between 7.32 and 24.82 m). The -1 -1 2 SI equation was: SI = e(lnHdo-12.476(A -Ab )) with an R value of 0.406 at p < 0.0001 (chosen as 30 yr in the present study). The equation indicated that 14, 18, 22, 26, and 30 m trees belonged to site classes Ι, ΙΙ, ΙΙΙ, ΙV, and V, respectively.

Boshier 1 & John J. MacKay 1* Dalbergia is a pantropical genus with more than 250 species, many of which are highly threatened due to overexploitation for their rosewood timber, along with general deforestation. Many Dalbergia species have received international attention for conservation, but the lack of genomic resources for Dalbergia hinders evolutionary studies and conservation applications, which are important for adaptive management. This study produced the frst reference transcriptomes for 6 Dalbergia species with diferent geographical origins and predicted ~ 32 to 49 K unique genes. We showed the utility of these transcriptomes by phylogenomic analyses with other Fabaceae species, estimating the divergence time of extant Dalbergia species to ~ 14.78 MYA. We detected over-representation in 13 Pfam terms including HSP, ALDH and ubiquitin families in Dalbergia. We also compared the gene families of geographically co-occurring D. cochinchinensis and D. oliveri and observed that more genes underwent positive selection and there were more diverged disease resistance proteins in the more widely distributed D. oliveri, consistent with reports that it occupies a wider ecological niche and has higher genetic diversity. We anticipate that the reference transcriptomes will facilitate future population genomics and gene-environment association studies on Dalbergia, as well as contributing to the genomic database where plants, particularly threatened ones, are currently underrepresented. Te genus Dalbergia Linn. f. (Fabaceae: Faboideae) contains around 250 species, many of which are globally recognized for their economic value.
