News from the Centre of Competence on the Origin of Timber

Participation at conferences and conventions, new developments, exchanges with visitor groups, research trips: things are happening here! Current information about the work of the Centre of Competence can be found here.

++June 10-11, 2021++ Week of the Environment

At this year's Week of the Environment, hosted by the German Federal President and the Deutsche Bundesstiftung Umwelt (DBU), the Thünen Centre of Competence, together with the University of Hamburg, is presenting innovative methods for identifying which woods are used in the production of paper. The background: paper production is a global business, and often the wood used as raw material comes from illegal logging. Aim of the project is to draw conclusions about the wood species used for paper products, by means of light microscopic or chemotaxonomic examinations.

Also the barbecue charcoal sold in Europe is often falsely declared. Within a DBU funded project, carried out at the Thünen Institute, references for the identification of tropical and sub-tropical woods in charcoal are to be established. The current progress of the work is presented.

++June 2, 2021++ Hamburg customs took action

During a routine inspection at the end of March 2021, customs officers from Hamburg's main customs office came across disassembled wooden chests with unclear information about the wood species. Based on the customs declaration, there was a suspicion that the wood could be a protected rosewood species. The suspicion was confirmed in cooperation with the Thünen Centre of Competence on the Origin of Timber. It was Indian rosewood (Dalbergia sissoo), a wood species that is covered by the import regulations of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). As the necessary import permits could not be presented by the importer, the wooden chests were confiscated by the customs authority.

++May 31, 2021++ causes of illegal logging

Which factors promote illegal logging? Matthias Bösch from the Thünen Institute of International Forestry and Forest Economics has analyzed this in a recently published study. In addition to confirming numerous widespread assumptions, it is shown that above all economic development and the institutional constitution of a country (e.g. the extent of the rule of law, the degree of government accountability, the presence of corruption) are of great importance for the existence of illegal logging. Armed conflict and population pressure, on the other hand, are seemingly less important.

The results of the study are also of interest for possible improvements of existing policies to combat illegal logging. For example, the identified factors could be used to better assess the risk of a country of origin in the due diligence practice of operators under the EUTR.

++May 15, 2021++ Cambio exhibition in Prato, Italy

From May 15 to October 24, 2021, the exhibition "Cambio" by the Italian designer duo Formafantasma is on display at Centro Pecci (Prato, Italy). It is about the interaction between the traditional disciplines of design, contemporary art and research.

The Thünen Institute of Wood Research is supporting the exhibition with various exhibits, including samples of protected woods and everyday wooden objects. Last year, "Cambio" was already shown at the renowned Serpentine Sackler Gallery in London (see below).

++Apr. 23, 2021++ explainer videos online

As part of the project "ProAmbiente II", short videos have been produced that clearly illustrate the work steps in the laboratory for the examination of wood species in fibreboard and paper as well as in charcoal. The project, which focused on skills development in the Peruvian forestry and timber sector, was carried out with the Peruvian institutions CITEmadera and CITEforestal and was funded by the German Society for International Cooperation (GIZ).

On the project website, these and other videos can also be found in Spanish.

++Apr. 20, 2021++ Testing orders show corona dip

After six years of uninterrupted growth in demand for anatomical wood species testing, the number of testing orders at the Thünen Centre of Competence has declined for the first time in 2020. This is possibly due to the long lockdowns and the reduced economic activity during the Corona pandemic. The focus of the investigations has shifted further to wood-based materials such as fibreboard, plywood, paper products as well as charcoal. Test requests from other EU countries also increased. In the case of genetic tests, the number of testing orders in 2020 was about the same as in the previous year. By far the largest number of requests came from companies dealing with wood and wood products.

++Jan. 22, 2021++ 3sat: Save the forests!

On 21 January 2021, the German TV channel 3sat broadcasted in its series "Wissen aktuell" the one-and-three-quarter-hour programme "Rettet die Wälder!"(Save the Forests!) about the many threats to forests, not only in Germany but also globally. One aspect: charcoal, sold in Germany, but often originating from countries like Nigeria, Paraguay or even from Eastern European natural forests. Experts at the Thünen Centre of Competence use a special 3D reflected-light microscopy procedure to check which wood species were used to produce charcoal. In this way they can often draw conclusions about its origin. Thünen researcher Volker Haag explains the procedure.

++Nov. 19, 2020++ online workshop in Peru

Due to Corona, numerous workshops and conferences have to be held online worldwide. Against this background, a GIZ (Gesellschaft für Internationale Zusammenarbeit) funded workshop focusing on wood species identification, which was planned for Lima (Peru), was conducted online.

To the great delight of the organising scientists at the Thünen Institute, this form of expert lectures was able to reach a much larger circle of interested parties than initially planned. The information on the workshop was passed on by the Peruvian research institute CITEmadera to research institutions in South America via numerous media channels (websites, Facebook etc.). The webinar "Opportunities and limits of anatomical wood ID, stable isotopes and genetic methods as tool for the regulation of the international timber trade" (authors: V. Haag, K. Paredes, G. Koch) was held on 19.11.2020 and was attended by more than 200 people from five countries (Peru, Brazil, Bolivia, Mexico, Germany).

In addition to the lectures, videos were presented that could be financed with the funds that were actually planned for the organisation of the face-to-face workshop. The positive response to the online workshop was still evident days after the date, with many positive feedbacks by e-mail.

++Nov. 16, 2020++ Charcoal studied throughout Europe

Which woods are used to produce the charcoal we usually use for barbecues? This has been analysed by the Thünen Institute and the WWF in a joint Europe-wide project. Between October 2019 and April 2020 a total of 150 bags of charcoal and charcoal briquettes were purchased in eleven European countries (Germany, Poland, Switzerland, Spain, Italy, Norway, Denmark, the Netherlands, Ukraine, Czech Republic and Belgium). At least 30 samples from each package were examined at the Thünen Institute of Wood Research with a 3D reflected-light microscope (Video) to determine the composition of the wood species contained therein.

The results have now been compiled in a WWF brochure (in German), which can be downloaded at ReseachGate. The corresponding scientific paper was published in the IAWA Journal in 2020.

++Nov. 9, 2020++ DIY STORES TESTED

The German television channel NDR tested in its magazine MARKT (broadcasted on November 9, 2020) how good the advice was when buying FSC-certified decking boards in the DIY stores OBI, Bauhaus and Hornbach. Within the testing team: Ulrich Bick, forestry scientist and certification expert from the Thünen Institute of International Forestry and Forest Economics. The conclusion: both the presentation of the goods and the advice provided by the sales staff varied greatly and was not always at its best.

++Oct. 28, 2020++ New CITES App

The ability to identify CITES-protected wood species is of prime importance in the implementation and enforcement of the CITES controls. A valuable support for computer-aided wood identification is provided by the new CITESwoodID app. Using this app, the most important CITES-protected timber can be identified on the smartphone or tablet by means of macroscopic structural features. The database CITESwoodID was developed by the Thünen Institute, the app was published by the Federal Agency for Nature Conservation (BfN).

The app contains descriptions and an interactive identification system of 46 CITES-protected timber (e.g. ebony, mahogany, rosewood) and 34 similar traded timbers, which can be mistaken for CITES taxa. It has been programmed for Android®, iOS® and UWP® operating systems and is available for free download in German, English, French and Spanish in the respective app stores since October 26.

++Sep. 29, 2020++ Exhibition Cambio reopened

The exhibition "Cambio" by the Italian designer duo Formafantasma in London's Serpentine Sackler Gallery has been opened to the public again. From September 29 onwards it can be visited (until November 4). The exhibition was originally scheduled for March to May (see below), but had to close due to the Corona pandemic. The Thünen Institute of Wood Research supports the exhibition with various exhibits, including samples of protected woods and articles of daily use made of wood. In videos, scientists of the Thünen Centre of Competence provide information about their work.

++Jun. 19, 2020++ New guide for timber tracking methods

Which scientific methods of the determination of wood species and origin are aavailable? Where are their strengths and limitations? A comprehensive overview is provided by the Global Timber Tracking Network's (GTTN) English-language guide, which has now been published at the end of the second project phase. It describes five methods (wood anatomy, genetics, stable isotopes, mass spectroscopy and NIR spectroscopy) that are used worldwide for the testing of wood and wood products. It also provides advice on the creation of reference data (databases). Thus it makes an important contribution to the harmonization of analytical methods within the global network of experts and institutions working on the containment of illegal logging.

39 scientists from 30 international institutions have contributed to the guide, including eight from the Thünen Centre of Competence on the Origin Centre Wood Origins. Financial support was provided by the BMEL in the context of the coordination of the GTTN project.

++Apr. 13, 2020++ Unusual workplace

As the staff of the Thünen Institute has officially been mandated to work in home office due to the Corona pandemic, Volker Haag from the Institute of Wood Research has taken the 3D reflected light microscope and the connected histology home with him. In his living room he is now examining 140 charcoal assortments from 11 European countries as part of the project "The European Charcoal Transition". The question is, which wood was used as resource for the charcoal. The work continues the investigations of the past years.

++Mar. 26, 2020++ Increasing demand for Wood testings

In 2019, the demands for testing the species and origin of wood at the Thünen Centre of Competence have increased significantly again. In the wood anatomy unit, 1,582 test orders were processed, around 14% more than in the previous year. In the genetic laboratory there were 343 tests, an increase of around 35 %. As in previous years, the main clients were trading companies with wood and wood products, including DIY stores, discounters, etc. There was also an increase in test orders for control authorities. Since the start of the Centre of Competence in 2013, a total of more than 8,200 orders have been processed.

++Mar. 23, 2020++ How is the EUTR implemented?

A survey by the Thünen Centre of Competence for the implementation of the European Timber Regulation (EUTR) among German importers has shown that the knowledge about the EUTR is low, especially among small companies outside the timber industry. However, these companies make up the majority of importing market participants.

Only 42 % of the 540 market participants interviewed knew about the EUTR and were aware that the regulation applies to them as well. However, together they account for 91 % of the total value of imported EUTR products of all respondents. 28 % of operators, which cover 76% of the import value, had installed a due diligence system. This reflects the high level of knowledge and implementation of major market players. The low level of implementation by small companies from outside the sector is mainly due to lacking information and indicates unequal access to information.

++Mar. 4, 2020++ Cambio exhibition in London

From March 4 to May 17, 2020, the Serpentine Sackler Gallery in London will host "Cambio", an exhibition by the Italian designer duo Formafantasma (due to Corona: closed to the public until further notice). Their work deals with the ecological and political responsibility of design. The focus is on natural building and construction elements such as wood. With this exhibition, the gallery creates a space for interaction between the traditional disciplines of design, contemporary art and research.

For the exhibition, the Thünen Institute of Wood Research has identified the wood species of around 40 wood products and papers and has made numerous protected woods available on loan. In videos, scientists of the Thünen Centre of Competence provide information about their work.

++Feb. 20, 2020++ Garden decking seminar

For the seventh time already, the German association GD Holz and the Thünenen Institute of Wood Research jointly organize a garden decking seminar on the Campus Hamburg-Bergedorf. It will deal with wood species for decking constructions, durability classification, NFC materials, legal aspects, but of course also questions of wood supply in the context of sustainable forest management. With around 130 participants from practice, trade and research, the event is again very well attended.

++Jan. 17-26, 2020++ Participation in the Green Week Fair

This year, the Centre of Competence is participating again at the International Green Week in Berlin, the world's largest fair of agriculture and nutrition. In the Hall 23a, the Thünen wood detectives explain to visitors how the import of wood and wood products from illegal logging can be detected by identifying the species of wood and checking its origin. This time the focus is on paper. The attraction is a table where the guests themselves can try to assign vessel elements – ultra-small structures, which are necessary for the determination of wood and which can still be detected in paper.

++Oct. 4, 2019++ Minister visits Centre of Competence

On 4 October 2019, Federal Minister of Agriculture Julia Klöckner visited Hamburg-Bergedorf to find out about the Thünen Centre of Competence on the Origin of Timber and the three Thünen institutes of Wood Research, of Forest Genetics and of International Forestry and Forest Economics. She emphasised the importance of the Centre of Competence for curbing illegal logging and effective consumer protection and acknowledged the importance of research in adapting our forests to climate change.

++Sep. 10, 2019++ Forest economists inform themselves

On the occasion of the 51st Colloquium on Forest Economics, about 25 scientists from Germany, Austria and Switzerland met at the Thünen-Institut in Hamburg-Bergedorf. Besides the scientific exchange, the thematic focus of this year's colloquium was on the implementation of the German Timber Trade Security Act (Holzhandelssicherungs-Gesetz, HolzHSiG). The scientists seized the opportunity to visit the Thünen Centre of Competence as well as a Hamburg timber trade company.

++Sep. 4, 2019++ Filming Firewood

On September 4, a TV team of the German broadcasting corporation NDR visited the wood anatomy laboratory of the Thünen Centre of Competence. They filmed how the experts analyse imported firewood offered for German fireplaces. Firewood is subject to the EU Timber Regulation and must not come from illegal logging when imported into the EU. The investigation of the batches revealed some surprises. The television film will be broadcast within the framework of the NDR documentary series "45 Min" on January 20th, 2020.

++Aug. 17, 2019 W wie Wissen++

In its programme of August 17, the German TV-magazine "W wie Wissen" broadcasted a report on the problem of importing charcoal from countries with a high corruption factor. It presented an alternative from Namibia, in which invasive foreign thorn bushes are used for the production of charcoal. Wood scientist Volker Haag from the Thünen Centre of Competence explained how his Institute can test charcoal samples to determine from which woods the charcoal was produced.

++May 20-23, 2019++ Symposium in Beijing

The Thünen Centre of Competence on the Origin of Timber was prominently represented with five presentations during the IAWA-IUFRO Symposium "Challenges and Opportunities for Updating Wood Identification" and GTTN ASIA Meeting in Beijing. The current research work and services of the Centre of Competence, in particular in the fields of fiber identification, determination of charcoal as well as genetic proof of origin of Asian commercial tree species (Siberian larch and Mongolian oak) were in great demand. Within the framework of the two events with 90 participants from 11 countries, closer cooperation between the Centre of Competence and the Chinese Academy of Forestry (Research Institute of Wood Industry) was agreed.

++Apr. 9, 2019++ New guide for methods and experts

Are the accompanying documents correct when importing wood and wood products? Do the wood species and its origin match the information in the documents? In order to be certain in cases of doubt, the inherent wood characteristics must be examined. There are various methods (e.g. anatomy, genetics, isotopes), and depending on the question, one method will be more suitable than the other. The Global Timber Tracking Network (GTTN), scientifically coordinated by Nele Schmitz from the Thünen Institute of Forest Genetics, has developed a guide that provides an overview of the currently available wood tracking and identification systems (Timber Tracking Tool Infogram). The infogram links to a list of all experts, currently working in this field worldwide, including the scientists of the Thünen Centre of Competence.

++Apr. 5-6, 2019++ Music Fair in Frankfurt

At this year's music fair „Musikmesse“ in Frankfurt, the Thünen Centre of Competence provided information on tropical woods used in instrument making. Gerald Koch and Volker Haag from the Thünen Institute of Wood Research were available to to answer questions about the ownership or trading of musical instruments with components made of CITES-protected woods.

++Apr 3, 2019++ Article in „Nature“

In April, the renowned scientific journal "nature" took up the topic of illegal trade in protected tropical timber. The article presents the international efforts to verify the species and origin of suspect timber. In this context it also reports on the possibilities of the Thünen Centre of Competence to find out which wood was used for the production of charcoal by means of innovative 3D microscopy. The Thünen experts found that a significant proportion of the charcoal used in Europe comes from tropical timber.

++Feb. 4, 2019++ Increasing numbers of test orders

Gratifying results for the past year: In 2018, the Thünen Centre of Competence again processed a rising number of test orders. The division '​​anatomical species determination' recorded an increase of about one third compared to the previous year, mainly due to increased inquiries from the trade, control authorities and NGOs. In the division 'genetic analysis', the number of tests remained at the same level, with increasing demands from timber trading companies.

++Dec. 3, 2018++ Atlas of vessel elements published

Unprinted paper products, which are increasingly being produced in Asia, fall under the EUTR. It is difficult to check which woods were used for papermaking because the high degree of processing means that no wood structures are left. One possibility is the microscopic examination of certain plant cells, the vessels. They can yet be found in the paper and have characteristic shapes. Scientists from the Thünen Institute of Wood Research and the University of Hamburg have now created an “Atlas of Vessel Elements“, which contains references for a variety of Asian woods. With these references, testing laboratories are enabled to prove the use of Asian woods in papers.

The atlas is also available online.

++Oct. 15, 2018++ New guidebook released

Compact information about the European Timber Regulation (EUTR) and the Thünen Centre of Competence on the Origin of Timber can be found in the newly published guide "Trading Wood and Wood Products Legally". What due diligence do market participants have? How does the anatomical determination of wood species work? In which types of wood can the origin be genetically recognized? How does the EUTR affect timber merchants and timber markets? These and other questions are clearly explained in the 32-page brochure (in German). The guidebook in DIN A5 format can be obtained free of charge from the secretariat of the Centre of Competence (holzherkuenfte@  thuenen.de) or as a PDF file on the Thünen website.

++Oct. 8-9, 2018++ Five Year Anniversary Event for EUTR

In March 2013, the EU Timber Regulation was enacted. At the same time, the Thünen Centre of Competence on the Origin of Timber was founded. To celebrate this anniversary, the Centre of Competence held a German/English language event “Wood trade and Forest Conservation – Five years of EUTR” in Hamburg. This symposium illuminated the experiences made to date in order to draw conclusions for the further development. The event was targeted to a German and international professional audience, especially for the affected enterprises.

Further information and the lecture sheets can be found here.

++Aug. 27, 2018++ FSC suspends DANCOAL

The Forest Stewardship Council (FSC) has forbidden the Polish wood charcoal manufacturer Dancoal to use the FSC Certification Label on its products. The enterprise has put wood charcoal briquettes with the sustainability label on the market, but had included some tropical wood from non-FSC certified forestry. Studies by the Thünen Centre of Competence on retail samples led, among other things, to the suspension. The German discounters Aldi South and Lidl both removed the Dancoal wood charcoal briquettes immediately. The suspension remains in effect until Dancoal can prove correct company procedures.

++July 18-22, 2018++ Interforst Munich

The Working Group for Wood Anatomy of the Thünen Centre of Competence provided information on possibilities for the determination of wood type in the context of the EUTR (Import of Wood and Wood Products from Legal Harvesting) and CITES (Protection of Endangered Species) at the BMEL Stand at the Interforst Trade Show in Munich. The public was predominantly interested in the numerous presented samples of tropical wood types. Fruitful conversations were held with interested visitors. Matthias Dieter of the Thünen Institute of International Forestry and Forest Economics held a lecture on the use of wood and climatic effects on the use of wood.

++June 28, 2018++ Workshop in Cameroon

The Global Timber Tracking Network (GTTN) had its Africa regional meeting in Yaoundé, Cameroon on 27-28 June, with 25 participants coming from across the continent and bringing experience from within research institutes (amongst others Thünen Institute of Forest Genetics), authorities, ngo’s as well as private companies. On the first day presentations were given on the current development of wood identification methods in Africa and on the interests and barriers for timber tracking. On the second day the participants identified available and needed capacities for timber tracking and species to be prioritised. Finally, ways forward to strengthen regional cooperation were discussed. The meeting was closed by a visit to a local saw mill.

Further information on the GTTN website.

++June 14, 2018++ New DBU Project

The German Federal Environmental Foundation (DBU) is supporting the cooperative project "Identifying tropical wood in paper – chemo taxonomy and anatomy to identify mixed tropical hardwoods" together with the University of Hamburg and the Thünen Centre of Competence, beginning in August 2018. Background: Large portions of the paper products used in Germany are currently produced in Asia. The project shall help to determine the important Asian wood varieties. Only in this manner can it be proven whether wood types of uncertain origin or even protected tropical woods are processed. For this purpose, chemical methods will be developed and characteristic morphological wood cell structures identified and included in reference databases.

++Apr. 12, 2018++ Music Fair Frankfurt

This year, the Thünen Institute is again joining the Frankfurt Musikmesse (Music Fair) with an exhibition by the Thünen Centre of Competence (April 11-14, 2018). The centre provides information about the problem of protected woods in the building of musical instruments and presents samples of typical woods, including palisander and African Blackwood. Many visitors, including musicians such as Darryl Jones, bassist for the Rolling Stones (photo), have visited the exhibition.

++Mar. 2, 2018++ Five years EUTR

In March 2013, the EU Timber Regulation (EUTR) came into force, which aims to ban imports of illegally logged timber and products made from it. At the same time, the Thünen Centre of Competence on the Origin of Timber was founded at the Thünen Institute. During this time, the Centre has successfully processed more than 3,000 test orders for the anatomical identification of wood species (equivalent to around 35,000 individual samples). In addition, nearly 1,500 wood samples were submitted for the genetic verification of the wood species and / or origin. The expertise now extends to the analyses of fibreboard, paper / products and charcoal. In addition, the Center has expertise in assessing certificates and legality. Based on these interdisciplinary work, the Centre has been established as central contact facility for government agencies, the timber trade, consumers and associations to verify the species of wood and/or wood products and their origin.

++Dec. 20, 2017++ Annual Requests hit the 1000 Mark

In the year 2017, the Centre of Competence received more than 1000 requests to anatomically determine wood types. The 1000th test assignment was completed in mid-December 2017. At its launching in 2013, the Centre of Competence received only one third as many requests. Now, as in the past, the majority of the testing assignments come form private business (wood dealers, dicounter, home repair markets, furniture companies, etc.) But monitoring agencies and NGOs regularly request help from the Centre of erCompetence . Requests from other European countries are also increasing steadily.

++Nov. 27, 2017++ New Project on Wood-DNA-Barcoding

The German Federal Environmental Foundation (DBU) supports a new project on the genetic identification of tree species in processed wood products at the Thünen Institute of Forest Genetics in Großhansdorf Wood composite products such as particle boards are often composed of wood from several tree species. The DNA of the contained wood can be highly degraded, and the DNA quantity from single species can be low. For these reasons, the detection of illegally logged wood using existing methods is very difficult in such products. In the next three years the Thünen Institute of Forest Genetics in collaboration with the German Timber Trade Federation (GD Holz) will develop new genetic markers and robust analytical methods that allow the detection of several genera and related species of deciduous trees and conifers especially in such wood composite products. The focus is on the differentiation of frequently used genera, such as pines, Douglas fir, and bangkirai, among others.

++Sep. 27, 2017++ International Visitors

The significance of the Centre of Competence is increasingly recognized in an international context. On September 27, a delegation of 15 persons of the Malaysian Timber Council (MTC) visited the Centre for an exchance of experience. On September 22, Dr. Mitsuaki Yamagata (Forest Economic Research Institut, Tokyo) and Mr. Yuichi Ikuta (Japan Woody Bioenergy Association) visited the Centre to discuss the implications of the new Japanese law against illegally logged timber. On September 19, scientists of the Centre of Competence informed a delegation of the Chinese State Forestry Administration about their activities within the framework of the China-Germany Working Group for Forestry.

++Aug. 22, 2017++ Wood charcoal in focus

Just in time for the summer barbecue season, two German television stations took a look at wood charcoal. The Thünen Competence Center for Wood Origin studied various barbecue charcoal a brands available in Germany on behalf of the WWF, various consumer protection organizations and commercial enterprises The background: the wood charcoal available for purchase in Germany is to a large extent imported. The main export countries are Poland, Nigeria and Paraguay. Deviant from the declaration, the Thünen experts found tropical woods in various samples. The results of the study were reported almost simultaneously by NDR aktuell, the NDR magazine Panorama3 and the ZDF magazine frontal 21 on August 22, 2017.

++June 7-9, 2017++ New CITES listing in focus

Three days of intensive information on the consequences of the new CITES listings were provided at the Thünen Centre of Competence in Hamburg. The protections, linked to inclusion the CITES list for all varieties of palisander and of Bubinga, present challenges for dealers and manufacturers of musical instruments and high value furniture, but also for the entire wood trade. On June 7, more than 120 dealers, manufacturers and representatives from agencies, associations and NGOs came to an information event and an intensive exchange of information and opinions. Subsequently scientists and agency representatives from 26 countries took part in an international workshop during which the emphasis was on the determination and differentiation possibilities for CITES protected wood. Please find more information here (in German).

++Apr. 10, 2017++ Music museum of Barcelona

In an effort to understand how different types of wood were used in the production of historical musical instruments, Volker Haag of the Thünen Institute of Wood Research and Valentina Zemke of the University of Hamburg visited the famous Barcelona Music Museum (Museu de la Música de Barcelona) as part of a COST Action. Background: The early instrument builders knew the different tone effects of various woods, based on their structural characteristics. That is why there is great interest today on which types of wood the old masters like Stradivari or Torres used. Since for obvious reasons, the examinations had to be done non-destructive. Thus, the scientists used a new 3D-reflected-light microscopy method. In 11 guitars, built between 1650 and 1953, they were able to successfully identify the wood species of 120 individual parts. The results will be presented at a conference in Brussels in October 2017.

++ Apr. 5, 2017++ Control at the Frankfurt Music Fair

Since January 2017, all species of rosewood (more than 250), which are frequently used as components for musical instruments, are listed in Annex B of the Washington Convention on International Trade in Endangered Species (CITES). The trade of items with rosewood requires now the presentation of CITES export and import documents as well as the legal obligation to keep records. Now, the compliance with these CITES regulations has been checked on request of the main customs office at the Frankfurt Music Fair.

Before beginning of the fair, Dr. Gerald Koch checked about 700 instruments with support of Dr. H. G. Richter. According to the main customs office, no CITES documents were available for 130 instruments with components of rosewood so that their presentation on the fair was not allowed. In order to inform traders and visitors of the fair about the new important regulations, Gerald Koch gave a lecture at a meeting of the Society of Music Merchants and participated in a panel discussion on the topic ‘Trade of CITES-protected woods in musical instruments’.

++Mar. 1, 2017++ DBU Expert Workshop on Timber Control

In order to find methods to uncover and fight the illegal logging of timber, an expert workshop of the Deutsche Bundesstiftung Umwelt DBU (German Federal Environmental Foundation) was held on March 1, 2017 in Osnabrück with numerous specialists from the Thünen Centre of Competence.

Cajus Ceasar, member of the German Federal Parliament and DBU curatorium member, stressed the need for practically viable and legally sound methods available to identify illegally imported timber and paper products. This does not only affect tropical forests but also forests in moderate climate zones. For genetic procedures for the monitoring of origin, reference samples are needed from the countries of origin. These are not always easy to obtain, according to the Thünen expert Bernd Degen. Among other things, the DBU has funded a project on the setting of a reference data bank for white oak. Other methods concerning the identification of wood in paper and fiber boards were also presented at the workshop.

++Feb. 15-16, 2017++ Kick-off meeting GTTN Phase 2

The Federal Ministry of Food and Agriculture (BMEL) in Bonn hosted the kick-off meeting of the Global Timber Tracking Network (GTTN) starting its second phase. The GTTN project was initiated in 2012, financed by the BMEL and coordinated by Bioversity International. The following three years will be further supported by the BMEL while the coordination is taken over by the European Forest Institute (EFI). The Thünen-Institute is part of the GTTN secretary and is responsible for the scientific support of the project co-ordination.

The meeting invited internationally renowned experts in the different timber tracking methods (based on genetic, chemical or structural wood properties) to give an update on recent scientific developments. But especially diverse user organisations were present to inform us about the actual and potential applications of the tools. These introductions led to fruitful brainstorming during workshops on the second day about the future tasks of the GTTN in standardising the methods, building a global reference database and promoting the use of the tools to curb illegal logging and related timber trade.

++Jan. 20-29, 2017++ International Green Week Fair

Die Fahnen der Grünen Wochen sind grün mit gelben Schriftzug

On this year's International Green Week (food and agriculture fair) in Berlin the Thünen-Institut exhibited several topics in the scope of forests and timber. Experts of the Centre of Competence presented various exotic wood samples, and informed about their research and their activities on identification of wood species and geographic origin. The Green Week attracts several tens of thousands of visitors every year.

++Dec. 15, 2016++ Radio Report on Environmental Crimes

On December 15, 2016 the Bavarian Radio Network broadcasted a half-hour feature on environmental crimes: "Billion dollar trade in poaching and illegal hunting". An important topic in addition to the trade in reptiles and other animals as well as illegal fishing was the illegal trade of wood, one of the most financially profitable sectors of environmental criminality. Thünen scientist Matthias Dieter described the environmental consequences, particularly  for tropical forests, and spoke about the difficulties in monitoring local logging areas and introduced the activities of the Thünen Centre of Competence. In the mean time, many German wood trading enterprises use the expertise available there to remain in accordance with their legal obligations and to protect themselves against fraud.

++Dec. 6, 2016++ Politician Steffi Lemke visits Centre

Prominent visitors on St. Nicholas’ Day: On Dec. 6, Steffi Lemke, the Parliamentary Secretary of the German Parliament's BÜNDNIS 90/DIE GRÜNEN fraction, Katrin Blaufuss, specialist for nature conservation and David Hoffmann were guests of the Centre of Competence in Hamburg. In addition to insights into the practical work of the centre (the microscopic determination of wood products, wood charcoal and paper) the visitors were informed extensively about the significance of global market analysis and certification systems for wood. In the discussion with the Thünen scientists, Gerald Koch, Matthias Dieter and Ulrich Bick, criticism was also voiced with regard to the implementation of the EUTR – above all the exceptions of certain product groups and the slow implementation of the EUTR in other EU States. Steffi Lemke praised the "excellent work" of the Centre of Competence on Twitter.

++Dec. 2, 2016++ Soon DNA-tests on timber in Ghana

In the period 28.11.16 to 02.12.2016 scientists from the Thünen-Institute of Forest genetics attended a meeting of the LargeScale project at the Forest Research Institute of Ghana (FORIG) in Kumasi. During the stay the scientists of the Thünen-Institute further supported FORIG with the setup of a genetic laboratory. The support includes equipment, lab consumables and training of technical and scientific staff.

From 2017 the lab at FORIG should work as a regional reference lab for West Africa and should be able to apply DNA-tests on species and origin for important African timber species such as Khaya, Sapelli, Iroko or Sipo.During the meeting the Thünen-scientists discussed with representatives of five West African countries concrete steps of sampling and genetic testing in order to ensure the trade of timber from legal harvests.

++Nov. 14-15, 2016++ Focus on Wood Charcoal

At an international wood charcoal forum of the BIAG (Barbecue Industry Association Grill e.V.) on November 14-15 in Berlin, Ulrich Bick, Gerald Koch and Sergej Kasuro of the Thünen Centre of Competence informed about the certification of wood charcoal and about possibilities to anatomically determine wood charcoal components. The topic has been of high interest to the public and media since the summer months. Even though wood charcoal and briquettes are not yet covered under the European Timber Regulation (EUTR), leading manufacturers and trade organizations at the symposium spoke out for a certification system (chain of custody) for wood charcoal which would also make information on the wood origin available.

++Oct. 7, 2016++ New gene markers for white oaks

At the Thünen Institute of Forest Genetics scientists developed together with colleagues from the USA and Russia a new set of gene markers for determining species and origin of white oaks. With these gene markers a proof of the continental origin (Asia, Europe or America) of wood from white oaks is possible using the differences in the DNA fragment patterns. Recently, in the international wood trading market an increase of false declarations of the origin of white oak timber has been observed. The most spectacular case is the conviction of the company "Lumber Liquidators" in the USA carrying a penalty of more than 13 million US$.  

The new gene markers have been recently published in the journal PLoS One: Schroeder H, Cronn R, Yanbaev YA, Jennings T, Mader M, Degen B, Kersten B (2016) Development of molecular markers for determining continental origin of wood from White Oaks (Quercus L. sect. Quercus). PLoS One 11 (6): e0158221, DOI:10.1371/journal.pone.0158221

++Oct. 6, 2016++ GD Holz visits Centre of Competence

On October 6, about 40 members of the northern state group of the GD Holz (Greater Association of German Wood Dealers) visited the Thünen Centre of Competence for information on current questions about the application of the Wood Trade Regulation EUTR and about the public acquisition of wood products in Germany. Among other things, Gerald Koch presented an update on methodical progress in the identification of woods in wood materials, paper and wood charcoal. A subsequent lecture by Ulrich Bick provided insight to the currently controversial public acquisition guidelines for wood products and requirements for certification.

++ Sep. 28, 2016 ++ New App for Timber Identification

The knowledge about identification and utilization of commercial timbers is of prime importance not only for wood experts and control authorities, but also for the timber trade and wood processing companies. The database macroHOLZdata has been established as an important instrument for computer-assisted wood identification which is now available as App version for iPads. The database offers:

  • an interactive identification of 100 important trade timbers based on macroscopic features which can be observed with the unaided eye or with a hand lens,
  • numerous high quality illustrations of wood characters and timbers alike featuring transverse and longitudinal surfaces,
  • a database with pertinent information on wood properties, processing, and utilization.

The database is also well suited for education and advanced training in the timber industry as well as self-study for all wood-interested persons. Further details about the App are available at https://appsto.re/de/xS-Zcb.i

++ Sep. 26, 2016++ John Lennon’s Guitar

The September edition of the magazine forschungsfelder deals exclusively with forests. One contribution is dedicated to the Thünen Centre of Competence on the Origin of Timber. The article narrates how the centre exposed the illegal import of a container load of of Wengé, a rare tropical wood, in the port of Antwerp with the help of Thünen experts. It describes the characteristic smell of Brazilian Rosewood, a strongly endangered wood that was previously used for the neck of electric guitars. In this context, the article reports that the experts even were given a guitar from Ex-Beatle John Lennon to examine. The article for downloading: The secret of the plywood (in German)

++ Sep. 23, 2016++ Handbook for UN Organization

An international group of experts on wood identification has prepared a guidebook with standards for forensic timber identification for the UN Organization “United Nations Office on Drugs and Crime” (UNDOOC). The handbook is planned to help control agencies find suitable methods to deal with illegal timber trading and to document reliable data for the courts. Here the entire process is considered, starting with the inspection of timber imports through to the taking of samples and on-site examinations as well as laboratory analysis. The Thünen Centre of Competence participated in the drafting of the handbook with the participation of Dr. Gerald Koch und Dr. Bernd Degen.

++Sep. 10-11, 2016++ Festival of the Future

Together with colleagues from the German Federal Agency for Nature Conservation (BfN) the Thünen Centre of Competence on the Origin of Timber took part in the large environmental festival hosted in Berlin by the German Federal Ministry for the Environment from September 10-11, 2016 to celebrate the ministry’s thirtieth anniversary (Festival of the Future: Environmental Policy 3.0). The presentation of BfN and Centre of Competence drew particular interest on the topic CITES woods – endangered and protected woods, mostly from the tropics and subtropics. The trade of these woods is controlled by the Washington Convention on International Trade in Endangered Species. The colleagues brought wood samples to the event and explained how they can determine wood species and even genetically test the origin of some species.

++July 7, 2016++ Assessing Wood Charcoal

On behalf of an Austrian consumer agency (Konsumentenschutz der Arbeiterkammer Oberösterreich) the Centre of Competence evaluated various wood charcoal samples to identify the woods used. In the anatomical study, a new microscopy technique was used for the first time (reflected-light microscopy with a polarized light, digital composition of images of various deep levels with a special software), made possible through a comparison of structures of the wood charcoal with the microscopic reference images. In some samples it could be proven that the wood did not comply with the declaration on the packaging. More information: Press release from July 18,2016 (in German).

++June 30, 2016++ FSC visits the Großhansdorf Instititue

On the occasion of the full meeting of the German Section of the FSC (Forest Stewardship Council) in Hamburg, a group of FSC representatives visited the Thünen Institute of Forest Genetics in Großhansdorf in order to gain insight into the work of the Centre of Competence on the Origin of Timber. After a short introduction on current topics, visitors could personally view the practical work in the laboratories. One of the excursion participants expressed her impression: “You have managed to bring light into the ‘black box’ of the possibilities of genetic analysis for me.”

++June 28-19, 2016++ EUTR Workshop in Sopron

Dr. Gerald Koch of the Thünen Institute of Wood Research was the German representative at a EUTR Workshop in Sopron, Hungary and presented the work of the Centre of Competence. In discussions he found that some EU member states were not adequately familiar with the requirements for the implementation of the EUTR, particularly the wide variety of timber products, which are regulated by the EUTR. Workshop participants also estimated the significance of illegal wood harvesting and the resulting problems quite differently.
