Article Review: CIFOR Blog:: New timber tracking tools to bolster global fight against illegal logging

The post iss related to the new tracking method to curb illegal logging through tracing the species DNA that was discussed in the workshop held in Kuala Lumpur, Malaysia.  The studies using DNA market to identify timber species and analyze genetic variation in the forest has been carried out for more than ten years. This system is coherent with the existing  EU FLEGT requirement and Lacey Act that has been debating to minimize the risk of illegal logging timber products to enter EU and US market.

What is it about?
The Global Timber Tracking Network (GTTN) promotes the use of innovative control tools based on the application of DNA and stable isotope research to identify timber species and trace their origins. The Global Timber Tracking Network aims to create a global database featuring genetic and stable isotope markers for commonly traded timber species, a landmark tool designed to reinforce certification standards and legislation and to complement existing paper-based documentation that can be easily falsified. 

How does it work?
Through the DNA and stable isotope markers as the legit information (as indicator in the assessor checklist) enter into the database, where is also accessible to the importers. This  enables to importers to verify the precise species and origin of wood and wood products and provide tangible proof that the products were genuinely derived from a sustainably managed forest or other legally harvested timber.  


How would the wood sample be?
To create the database shall require integrating data generated by different research techniques and that has been collected by scientist working in various location around the world. 


What are the equipment use to test the wood sample, what are the total sample need to quantify and how long does it takes?  
A global standard (i.e.: similar FSC standard) for sampling and lab analysis of genetic and stable isotope data shall be establish in order to ensure the technique used to gather and analyze the data are repeatable and verifiable. 


Any successful pilot project? 
To date, just a handful of projects have created individual databases for certain timber species. 

Malaysia
The Forest Research Institute of Malaysia (FRIM) established an early database of tropical timber species using DNA fingerprinting data. The FRIM database has genetic data for:
  1. chengal (Neobalanocarpus heimii) -IUCN Red List
  2. ramin (Gonystylus bancanus) -IUCN Red List
  3. kempas (Koompassia malaccensis) (Traded Timber Species) (WIP) and 
  4. meranti bukit (Shorea platyclados)  (Traded Timber Species) (WIP)
Currently, the GTTN database shall be test whether the data generated by analyses of wood samples match the stated species and origin on the product label.

Africa
Double Helix will design and implement DNA Chain-of-Custody systems for several supply chains. To achieve this we are actively working with government partners, concession owners/managers and community groups. The project will create DNA barcodes for twenty important African timber species and will generate a map of genetic variation across the different participating countries for three commercial tree species: Ayou (Triplochiton scleroxylon), Iroko (Milicia sp.) and Sapele (Entandrophragma cylindricum). By the end of the project, the trade and Governments will have the ability to verify the species and origin of harvest of these timber species. It will provide a scientific, cost-effective method to verify claims and other supply chain documentation, enforce legislation and exclude illegally harvested timber from being laundered through legitimate supply chains. The genetic reference databases will be held by Bioversity International in Malaysia, the international coordination office for tree identification and origin assignment. Below are the countries covered under this project.
What are the major challenges or obstacle?
In Brazil, a key timber-producing nation believed to have the world’s greatest biodiversity of plant species, correctly identifying timber species is especially challenging, said Milton Kanashiro, a research geneticist at the Brazilian Agricultural Research Corporation (EMBRAPA). “Identifying species is a big problem in Brazil. Different species of trees often end up getting classified under one species because it can be difficult to properly identify so many species in the field,” Kanashiro said. “If species are not identified, we could be losing biodiversity without knowing it. And if you don’t know you are losing a species, you cannot properly protect it.”
My opinion of the major challenges for DNA Timber Tracking:
  1. Reaching agreement on standards may be the most difficult aspect of making the timber tracking system operational.
  2. The research takes time, have not fully define total isotopes needed for isotope marking
  3. At present only covers endanger species, and several tree species have overlaps of isotopes marker.
  4. Questionable about the type of equipment needed for the importer or the require knowledge by the importer to ensure they understand the system and also does not take a very long time to verify the legality of the timber in the port.
