newly published article on amazon wood species classification

A new article “Amazon wood species classification: a comparison between deep learning and pre-designed features” authored by André R. de Geus, André R. Backes, Alexandre B. Gontijo, Giovanna H. Q. Albuquerque, Jefferson R. Souza was published on Wood Science and Technology in March 2021.

The authors introduced a new wood dataset by a simplified image acquisition process and developed four deep learning models with transfer learning compared with traditional pre-designed feature method. The results showed that deep learning outperforms pre-design features for wood classification, indicating that it could be applied to assist untrained agents in wood classification.

Identification of mahogany wood veneer using portable NIRS

Tereza Pastore and her team published an article "Identification of mahogany sliced veneer using handheld near-infrared spectroscopy device and multivariate data analysis" on IAWA Journal recently. 

It is a pioneering study that allows identifying two native forest species listed in the CITES and three similar species. The PLS-DA (Partial Least Squares for Discriminant Analysis) models showed 96.5-100% accuracy in the samples’ discrimination among the five species. It is concluded that the portable NIRS (Near-infrared Spectroscopy) and the PLS-DA were suitable for the rapid identification and discrimination of the wood veneers.

Field Identification Manual for Ghanaian Timbers

Field Identification Manual for Ghanaian Timbers edited by R Arévalo, E Ebanyenle, A Ebeheakey, K Bonsu, O Lambog, R Soares and A Wiedenhoeft was published in 2020. It is one outcome of the Improving Sustainable Value Chains for Exports from Ghana program sponsored by the United Nations Industrial Development Organization (UNIDO). 

This manual provides a field reference suitable for timber inspectors to conduct routine field screening of more than 100 common commercial timber species from Ghana, using macroscopic and physical identification features.

New Postdoc Position in Wood Identification

The US Forest Service Wood Identification & Screening Center (WISC) at Oregon State University invites applications for postdoctoral fellowships in stable isotope and botanical provenacing for a two-year, fully funded, position in Corvallis, OR. The main goal of WISC is to support enforcement of the U.S. Lacey Act and Endangered Species Act with respect to the timber trade. Apply for this position by sending all application materials to Kristen Finch (Kristen.finch@oregonstate.edu) by April 1, 2021. Interested applicants should submit: (a) a curriculum vita with a list of publications, (b) the names of at least three professional references, their e-mail addresses, and telephone contact numbers and (c) a cover letter or email describing their interests and experiences in the topic area, goals, and how they meet the required position qualifications outlined below.

CITES Plants Committee (PC) document “PC25 Inf. 11 IDENTIFICATION OF TIMBER AND OTHER WOOD PRODUCTS–SUPPORTING INFORMATION” (PC25 Info Doc 11) is on the progress of updating. This document has been submitted by the Secretariat as an Annex to PC25 Doc.19 on Identification of timber and other wood products. It can be assessed at https://cites.org/sites/default/files/eng/com/pc/25/inf/E-PC25-inf11.pdf.

As communicated through Notification No. 2020/056, the CITES PC has agreed on the establishment of an intersessional working group on identification of timber and other wood products, co-chaired by Rosemarie Gnam (representative of North America), César Augusto Beltetón Chacón (representative of Central South America and the Caribbean) and Yan Zeng (representative of Asia).

For the first step, the CITES Secretariat has suggested inviting input to this document, since it can become the basis for their re-structuring the timber-ID page of the CITES website and get a clear picture of relevant stakeholders, experts and other resources. It is encouraged to contact the Working Members or Secretariat staff (Isabel Camarena: isabel.camarena@un.org) assigned to this CITES working group on communications.
