“Imagine there’s a forest” – inspirations from Francis Hallé

“Imagine there’s a forest” – inspirations from Francis Hallé

Published December 13, 2022 by Jakob Derks

Humans originate from arboreal primates, so to really understand the forest, you have to experience it from the canopy. This is what the famous French botanist and conservationist Francis Hallé believes. Despite his respectable age, the spry octogenarian had no issues demonstrating his capability to do so on the tree top path next the biosphere centre in the Pfälzerwald.

Located on the French border, in the middle of the largest contiguous forest in Germany, this centre is the location of the Wasgauer Gespräche/les entretiens du Wasgau. Every second year, this bilingual event brings together people from the French and the German sides of the border to talk about various nature-related topics. This year’s question was: how much nature do humans need? Speaking on behalf of EFI and the Integrate network, I was the only presenter to talk about the pragmatic need for wood, and how integrative forest management can be a solution for providing needed draw materials while also conserving biodiversity. This however does not mean that it is the best solution everywhere. In some places a more intensive management style makes sense, while in others the wise option is to leave nature to itself. And this is exactly the case made by Francis Hallé during the opening session of the event.

A week in the life of a marteloscopist

A week in the life of a marteloscopist

Published December 16, 2021 by Jakob Derks

The morning sky is still pitch black when the alarm goes off. I wake up in a hotel room on a grey busy rainy road in a post-industrial town in southern Luxembourg. Hitting the snooze button is not an option; daylight is scarce in late November and we should really reach the forest at dawn. There is still time for a sad corona-proof breakfast though, that is to be consumed in the hotel room. Crackers, instant coffee, jam, all individually packed in plastic of course. What is good for hygiene is not necessarily good for the environment.

Before sunrise, my colleague and I get to the site of our next marteloscope. The morning fog reduces the visibility to almost nothing, but luckily our memory manages to lead us back to the place we had visited with the local forester a month earlier. Despite the dense undergrowth we had managed to survey the perimeter of the square one-hectare stand in October, but not without cutting much of the regeneration along the borders that were obstructing the view and the functioning of our measurement equipment. A tedious effort, but one less task this week. Last time the foliage was still too dense to measure heights or spot tree microhabitats. Now that most of the leaves have fallen, we can continue the inventory. Yesterday we were still in the far north of this little country, to finish precisely those tasks for the previous site. Now we are ready to wrap up the inventory of the final marteloscope in Luxembourg.

Marteloskope – Selbstüberprüfung des forstlichen Götterblickes

Marteloskope – Selbstüberprüfung des forstlichen Götterblickes

Published August 20, 2021 by Jakob Derks

Hans von der Goltz, Jakob Derks

Am 29.-30. Juni diesen Jahres fand die jährliche Vorstandssitzung der ANW (Arbeitsgemeinschaft Naturgemäße Waldwirtschaft) unter dem Vorsitz von Hans von der Goltz und organisiert von Johannes Odrost statt. Zu diesem Anlass trafen sich die hochrangigen Forstexpert*innen in Massow, einem Forstrevier, das der Hatzfeldt-Wildenburg’schen Verwaltung gehört und von ihr verwaltet wird. Der Wald erstreckt sich über rund 7000 Hektar und wird überwiegend von der Waldkiefer dominiert. Die jahrzehntelange nachlässige Bewirtschaftung hatte zu dichten, überalterten Kiefernmonokulturen mit wenig Unterwuchs und Artenvielfalt geführt. Auf den kargen Sandböden Brandenburgs macht das die Bestände anfällig für Trockenheit und Brände. Mit dem Erwerb des Waldes durch die Hatzfeldt-Wildenburg’sche Verwaltung vor etwa zwanzig Jahren wurde eine neue Bewirtschaftungsweise eingeführt. Das Hauptziel besteht darin, die Widerstandsfähigkeit des Waldes zu erhöhen, indem die strukturelle Vielfalt maximiert, die natürliche Verjüngung gefördert und die Beimischung verschiedener Arten, gegebenenfalls durch Anpflanzung, begünstigt wird. Nach Jahren konsequenter selektiver Durchforstung, verbunden mit einer intensiven Bejagung und der gezielten Einbringung verschiedener Baumarten, hat sich der Wald verändert. Er ist deutlich üppiger, grüner und strukturreicher als die meisten benachbarten Bestände.

Uwe Schölmerich: a tribute by EFI Bonn

Uwe Schölmerich: a tribute by EFI Bonn

Published February 5, 2021 by Jakob Derks

In January 2021, our esteemed colleague Uwe Schölmerich, Head of the State Forest Enterprise Rhein-Sieg-Erft from the regional forest service “Wald und Holz NRW” retired. This blogpost is a retrospective on our fruitful collaboration with a forest manager who was rightly described by his colleagues as “deeply dedicated to both the forest and people”. 

When EFI opened a new office in Bonn in 2017, the few employees had little to no affiliation to their new surroundings, let alone to the forests in that region. As the former capital of Western Germany and a bustling hub of international organisations, Bonn was a strategic location more than anything else. 

After spending the first few months in a temporary location, EFI Bonn moved to its final premises on the Platz der Vereinten Nationen in 2018. From the first floor hallway of this building, many new employees caught their first glimpse of the forest embracing the city’s Western boundaries. What initially was no more than a background scenery, quickly turned into an impactful presence in our everyday work, as EFI Bonn slowly started to spread its roots into the fertile soils of the Lower Rhine Bay and its adjacent hills. 

The forest that they saw on the western horizon, the Kottenforst, turned out to be managed by a wise, dedicated and friendly man and forester named Uwe Schölmerich.

Stories of integrated forest management in Luxembourg

During times when polarisation seems to be on the rise on many levels, a growing number of forest managers is choosing to do the opposite and to bridge differences instead. The Integrate Network has since 2016 been exchanging information on forest management ideas that combine wood production with nature conservation, a feat which may sound contradictory to some but in many cases offers plenty of advantages compared to a segregated approach. The members, governmental organizations from 18 different European countries, reflect a diverse view on forestry, characterised by a variety of factors that differ from one region to another. The common theme is the belief that production and protection do not have to exclude each other, quite the opposite.

The open exchange of experiences in the Integrate Network is increasingly attracting interest, not only from policy makers but also from practitioners. The network of marteloscopes serves to demonstrate and visualise potential trade-offs between economy and ecology on a stand level, allowing on-field training for everyone with a professional or non-professional interest in forest management.

It is always exciting when new marteloscope sites are added to the steadily expanding list, but even more so when a new country decides to join the network. This was the case for the Grand Duchy of Luxembourg in 2019. ProSilva and the Nature and Forest Administration of Luxembourg contacted EFI to set up its first marteloscopes. As a Belgian I had been in Luxembourg several times before but still the beauty and the diversity of the landscapes of this small country never seize to amaze me.

Wald im Wandel: mein Interview mit dem Wandermagazin

Wald im Wandel: mein Interview mit dem Wandermagazin

Published March 24, 2020 by Jakob Derks

Der Wald bietet Antworten auf eine Vielzahl von sozialen und ökologischen Fragen. Forschungsprojekte des European Forest Institute haben jedoch festgestellt, dass die breite Öffentlichkeit über forstbezogene Themen häufig nicht umfassend informiert ist. Dazu gehört zum Beispiel, dass Menschen gerne Holzmöbel kaufen, aber gleichzeitig eine Bewirtschaftung der Wälder oft kritisch gesehen wird. Wir brauchen eine engagierte Kommunikation zwischen dem Forstsektor und der breiten Gesellschaft, um diese Verständnislücke zu schließen. Als internationale Wissenschaftsorganisation arbeitet EFI auf unterschiedlichen Ebenen (von lokal zu global) und mit vielfältigen Akteuren und Interessengruppen. Dazu zählt natürlich die Wissenschaft, aber auch Forstpraktiker*innen sowie Vertreter*innen von Politik, Gesellschaft und den Medien. Über die Veröffentlichung von wissenschaftlicher Literatur hinaus sind wir auch offen für den Austausch von Erfahrungen und Informationen über nicht-akademische Plattformen. Ein Beispiel dafür ist das Wandermagazin, eine etablierte deutsche Zeitschrift, die über Wandern und Erholung in der Natur berichtet. Sein Publikum ist typischerweise sehr an der Natur interessiert, aber nicht unbedingt fachkundig. Die Redakteurin Svenja Walter hat sich deshalb entschlossen, eine Sonderausgabe mit dem Schwerpunkt Wald in Deutschland herauszugeben. Neben einem Förster und einem Naturschützer wurde ich interviewt, um eine Einführung zum Zustand der Wälder in Europa und speziell in Deutschland zu geben.

Den Artikel können Sie hier lesen (auf Deutsch). Ich wünsche Ihnen eine anregende Lektüre!

EU forests after Brexit – future scenarios from four years ago

EU forests after Brexit – future scenarios from four years ago

Published February 10, 2020 by Jakob Derks

Before the Brexit referendum four years ago, when much of the media buzz revolved around the uncertain future of trade, immigration and stock markets, at the European Forest Institute we discussed its potential impact on forests and forest-related policy.

Even though there is no EU forest policy, there are a number of other policy instruments that directly or indirectly affect forests and their management. These range from the EU Timber Regulation or the EU Birds and Habitats Directives over the FLEGT and REDD programmes to the Common Agriculture Policy, all of which could be impacted by a possible Brexit.

Douglas-fir – firing up foresters since 1827

Douglas-fir – firing up foresters since 1827

Published January 17, 2019 by Jakob Derks

Douglas-fir (Pseudotsuga menziesii) is not just any tree. It is arguably one of the most controversial tree species in Europe. This controversy is mostly due to its success on this side of the Atlantic; it is the second most common non-native tree species in Europe and thus creates a lot of conflict potential. The debate has become somewhat polarised around the presumed invasiveness in sensitive natural areas on the one hand and the production of high-quality wood on the other hand. This book tries to provide the debaters with scientific data.
