In this article, I talk about the “mode of competition”, in other words whether trees of different species compete more of aboveground or belowground resources when growing in mixed stands. Additionally, I highlight the advantage of mixed forests in the context of climate change.
If you have read some of my articles like What factors determine whether tree species compete or complement each other?, you know how much I like mixed forests. Forests rich in tree species not only are known for providing higher levels of ecosystem services but also be prompter to cope with unexpected disturbances and climatic changes. However, the mechanisms of competitions in multi-species forests are all but clear. Scientists are still studying which combinations of tree species grow better in a particular environment or what factor promote or reduce a positive growth complementarity in secondary forests and/or plantations. In one of my latest posts on the blog Forest Monitor I have tried to explain in simple terms the concept of how complementarity for a give species can be positive or negative when growing in association with other species depending on resource availability.
The European Forest Institute is seeking two Junior Researchers to join its Resilience Programme, to conduct a global research and capacity-building project related to the future of employment and green jobs in the forest sector, in close collaboration with the International Forestry Students’ Association (IFSA) and the International Union of Forest Research Organizations (IUFRO).
EFI’s Resilience Programme focuses on the resilience of forests and livelihoods connected to them. We conduct research, policy support and networking on four strategic themes:
- The impact of global change and related risks on forest socio-ecological systems
- Policies and forest management practices to enhance forest biodiversity
- The rural/urban forest: policies and management practices to enhance the resilience of rural/urban areas – from green infrastructure to wood construction
- Resilience stewardship
The details of the job responsibilities and qualifications can be found here. Interested candidates are requested to send a CV (in English) including copies of academic degree certificates/diplomas with a motivation letter by Monday 15th October 2018, using our online application form. For more information about the positions, please contact Andrew Male, Head of HR & Administration:

A group of researchers from all over Europe worked together to release a unique database to the scientific community. Assembling data collected under the auspices of an EU Cost Action, the database BeechCOSTe52 gathers over 860,000 measurements of phenotypic traits. These data, from more than 500,000 beech trees growing in plantations located in 38 European countries, cover the entire range of beech’s distribution. Over 15 years of work have gone into producing the database; a vital resource for analyzing and understanding the beech’s adaptive capacity to climate change and the potential effects of climate on its distribution range.
Der Sommer 2018 war und ist immer noch ein ausgesprochener Feuer-Sommer für unsere Wälder in Deutschland und Zentraleuropa. Eine ungewohnt hohe Zahl von Vegetationsbränden zwingt zur Diskussion der Ursachen einerseits, regt aber auch zum Nachdenken an, was zukünftig getan werden kann und muss.
Erste schnelle Reaktionen befassen sich wie üblich sofort mit der Feuerwehr und der Frage, wie die Einsatzkräfte in Zukunft noch besser und effizienter vorgehen können – also der reaktive Ansatz und die Bekämpfung des Symptoms, aber nicht der Ursache. Selbstverständlich brauchen wir Feuerwehren, die bestmöglichst ausgebildet und ausgerüstet sind. Der Blick über unsere Ländergrenzen hinweg bietet zahlreiche Möglichkeiten, hier nachzubessern. Die European Forest Risk Facility und das weitere Netzwerk sind seit langem in diesem Bereich des länderübergreifenden “Exchange of Experts” tätig. Allerdings nicht nur auf reaktiver Seite sondern auch und vorallem in den Bereichen Prävention und Erhöhung der Resilienz.
Since 1995, the Bonn-based German expert for green impact investing ForestFinance has been planting forests in the project countries Panama, Peru, Colombia and Vietnam. Now, the reforestation company has just planted its ten millionth tree.
“In 2009, we planted and celebrated our millionth tree in Panama City in the presence of the Panamanian Minister of Environmental Affairs. Today – nine years later – we have increased this number tenfold. We have achieved this together with over 19,000 customers and environmentally conscious investors,” explains Harry Assenmacher, founder of the ForestFinance Group.
Programms of afforestation to create forests increase carbon capture and carbon sequestration, and help to anthropogenically improve biodiversity.

“We must act to halt and reverse the unsustainable use of nature – or risk not only the future we want, but even the lives we currently lead”, says Sir Robert Watson – chair of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). This is but one somber, yet realistic conclusion drawn from the most recent reports on biodiversity and ecosystem services.
By the end of March, IPBES approved four landmark science reports on biodiversity and ecosystem services for different regions of the world and published a report on land degradation and restoration worldwide. These reports, comparable to the IPCC reports on climate change, result from three years of work, involving more than 550 leading scientists from over 100 countries to assess the state of worldwide biodiversity and ecosystem services. The main findings draw a gloomy future, however not without mentioning the one or the other ray of hope.
The website for the project “SUstaining and Enhancing REsilience of European Forests” – or briefly SURE – is launched. It provides all the important information on the project, upcoming events, as well as material on the RISKplatform, a virtual communication tool for the European Forest Risk community.
If you are interested in experiences from both practice and science on how to best cope with risk and respond to disturbances, if you want to learn about developing and improving response strategies in policymaking and practical management be sure to check out the new website!
Coordinated by European Forest Institute’s Bonn Office and funded by the German Federal Ministry for Food and Agriculture, SURE is aiming at enhancing forest resilience and addressing disturbance related risks as an integral part of sustainable forest management through facilitating networking, learning and capacity building.
EFI Bonn’s fire risks senior expert Alexander Held was selected as a mentor for the Climate Change Immersive Story Accelerator Lookout360°, a new 6-month media support programme for journalists and producers who are eager to get started with immersive stories on climate change. The programme is a pilot project of the recently launched science-media initiative The Lookout Station initiated by European Forest Institute and the Global Editors Network.
Together with Alan Rusbridger, former editor-in-chief of Guardian News & Media
and Dr. John M. Reilly, Co-Director of MIT Joint Program on the Science and Policy of Global Change, and other mentors, Alexander Held will support a group of 10 journalists by providing his expertise in forest fires, silviculture and deer management.

Utilising our forests with care and understanding will ensure that they continue to deliver everything we value now and for generations to come. Wood is a much needed resource and will continue to be in future. The film wise use of our forests: the integrative approach aims at presenting Europe’s forest in this context.
In this short video, the European Forest Institute (EFI) looks at the key factors of increased forest fire risk in the Mediterranean region and advocates for a new vision based on shifting the focus from reactive fire suppression to long-term proactive fire prevention and forest management at the landscape scale.
