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.

Combining silviculture and ecology to benefit our forests – the Irish way

Ireland is one of the few countries in Europe that experienced almost complete deforestation in recent history with just over 1% forest cover remaining at the beginning of the 1900s. Since then, an impressive effort has been made by the State of Ireland and other stakeholders to increase forest cover – but the Irish plan to plant forests has also faced a lot of criticism. I have spoken with three experts on Irish forests: Jonathan Spazzi, Forestry Development Officer working for Teagasc, Aileen O’Sullivan, Environmental Technical Lead for Coillte Forest, as well as Padraig O Tuama, private forestry consultant specialising in clients interested in Continuous Cover Forestry (CCF) and former task leader for researching and promoting Continuous Cover Forestry (CCF) in Coillte Teo.

They have all joined forces to promoting the Continuous Cover Forest management (CCF) approach, to increase species diversity and forest conservation in Irish forests while as well enhancing timber value. As a proper tool to support their efforts both Teagasc and Coillte, in collaboration with ProSilva Ireland, have decided to establish several marteloscope sites in different forest types. Check out this interview to learn what has happened so far in Irish forestry, how the three would like to shape the future of their forests, and what they expect from working with marteloscopes.

Einmal FörsterIn spielen- EFI als Aussteller bei Woche der Umwelt

Artenvielfalt ist das diesjährige Thema der Woche der Umwelt, die auf Einladung des Bundespräsidenten Frank-Walter Steinmeier und der Deutschen Bundesstiftung Umwelt (DBU) stattfindet. Unter dem Motto „So geht Zukunft!“ erwarten die Teilnehmenden am 10. und 11. Juni 2021 spannende Diskussionen und ein attraktives Programm zu wichtigen Zukunftsfragen. Ausstellende aus Wirtschaft und Technik, Forschung und Wissenschaft und aus der Zivilgesellschaft präsentieren online ihre innovativen Lösungen für die Zukunft.

Aus über 600 Bewerbungen wählte eine durch das Bundespräsidialamt berufene Fachjury die besten Projekte aus und wir freuen uns, dass das Europäische Forstinstitut (EFI) als Aussteller dabei ist. Das EFI Bonn stellt das Konzept der Marteloskope, ein innovatives Trainingstool zur Visualisierung waldbaulicher Entscheidungen. Marteleloskope sind ca. 1 Hektar große Flächen, in denen alle Bäume nummeriert, kartiert und vermessen sind.   Übungen in den Martelskop-Flächen erlauben es, in die Rolle von Forstleuten zu schlüpfen und dank einer eigens dafür entwickelten Software, die auf Tablets bereitgestellt wird, virtuell forstliche Entscheidungen zu treffen. Hier ein kurzes Video zu den Marteloskopen (Link youtube).

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.
