Marteloskope – Selbstüberprüfung des forstlichen Götterblickes

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.

Forests as critical infrastructure? Integrated Forest Management and recreation for forests and people – Virtual Excursion during the Urban Forestry Days 23-24 March

How to bring more than 600 policy planners, decision-makers, practitioners, researchers and urban forestry enthusiasts into the forest in times of social distancing? The first day of the Urban Forestry Days (23 – 24 March 2021) held a special highlight for the participants, who joined from over 68 countries all around the globe. The two-day collaborative event of integrated Urban Forestry activities was hosted by the European Forest Institute (EFI), the European Forum on Urban Forestry (EFUF) and the Horizon 2020 CLEARING HOUSE project.

“Public involvement and engagement bring valuable information to decision-making processes”,

Renate Späth

After a day packed with the latest urban forestry developments, insights on integrated forest management and lively discussions about the role of urban forests for co-creating more sustainable cities, a virtual excursion brought the participants right into Kottenforst. Located in the southwest of Bonn in North Rhine-Westphalia, the 4.000 hectares peri-urban forest area serves as a stage to enjoy nature, recreate, meet people and engage in discussions. A group of urban forestry experts accompanied the visual experience. While live-commenting the virtual excursion, they shed light on environmental education, microhabitats, marteloscopes and the importance of enabling and enhancing dialogue about forests and forest policy. As part of a Q&A session, facilitator Maria Schloßmacher (EFI) encouraged participants to share their thoughts and ask questions directly to the experts.

Marteloscopes and Carbon – a missing piece of the puzzle?

Witten by Huntley Brownell and Andrew Stratton

Many readers of this blog are likely familiar with marteloscopes (if not, click here to read more). We think our story demonstrates the remarkable educational potential of this tool, and we would like to share it with you.

Our story begins deep in the Black Forest, outside of Freiburg in Germany. It was long, long ago, before corona times: the autumn of 2018. We were part of a group of MSc students studying Forest and Nature Management on a study tour from the University of Copenhagen, and we were brought to visit the Rosskopf marteloscope.

By now we all understand the limitations of virtual meetings; back then the forty of us, carefree and not at all socially distanced, took for granted the vibrant educational environment of in-person learning. With tablets in hand, groups of students and professors explored the marteloscope, observing, discussing, debating – sometimes passionately – the harvesting trade-offs we were considering in the exercise. Questions arose: how will our decisions affect stand biodiversity? How will the stand develop in the future if we harvest certain trees now? Are some microhabitats more important than others? What is biodiversity anyway? How much is that tree worth?

“Dialogue with interest groups in the forest needs to be intensified” – an interview with Thomas Haußmann

Thomas Hausmann, who has a background in forestry and is working with the the German Federal Ministry of Food and Agriculture since many years, was one of the initiators of the European Network Integrate, which is connecting people from forest management, and nature conservation, science and
policy-making to overcome political polarization and limited dialogue between sectoral silos. With almost 20 member countries and more than 100 demonstration sites, the network promotes the integration of nature conservation into sustainable forest management. We have spoken with Thomas about the history of the network, challenges faced and future perspectives.

Uwe Schölmerich: a tribute by EFI Bonn

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.

Once upon a time… there was a marteloscope.

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.

Ein zukunftsfähiges Waldkonzept entwickeln – das Projekt “Dauerwald”

Interview mit Hans von der Goltz

Hans von der Goltz ist Bundesvorsitzender der Arbeitsgemeinschaft Naturnahe Waldwirtschaft (ANW). Wir haben mit ihm über das neue ANW-Projekt “Dauerwald” gesprochen, über Chancen und Herausforderungen – und das Ziel, einen sowohl ökonomisch als auch ökologisch nachhaltigen Wald zu fördern.

Was ist eigentlich ein Dauerwald?

Ein Dauerwald ist ein Wald, in dem nicht nur verschiedene standortgerecht Baumarten, sondern auch Bäume unterschiedlichen Alters stehen. Er wird ohne Kahlschlag einzelbaumweise nach dem Prinzip der größtmöglichen Stetigkeit bewirtschaftet – Stetigkeit von Vorrat, Struktur, Zuwachs und ökologischen Grundlagen.

Warum brauchen wir Dauerwald?

Im Dauerwald führt relativ einheitliche Ausstattung aller „Waldetagen“ mit jungen, mittelalten und alten Bäumen zu Windruhe und zu einer deutlich höheren Luft- und Bodenfeuchte. Hierdurch werden Maximaltemperaturen gesenkt. Einzelne, besonders trocken- oder hitzeempfindliche Baumarten leiden natürlich auch, aber andere überdauern. Im Gegensatz zu wenig strukturierten Reinbeständen verschwindet bei den aktuellen Herausforderungen des Klimawandels nicht der ganze Wald, sondern eben nur einzelne Bäume. Der Wald bleibt erhalten – und das muss aktuell unser wichtigstes Ziel sein.
