Celebrating #EarthDay2022 with a tribute to microhabitats, the building blocks of biodiverse ecosystems

It is common practice to celebrate Earth Day by highlighting the vast array of habitats on Earth and the ecosystem services they provide – but…

Why should we all learn to think like foresters

Interview with Lisa Hafer, WaldHaus Freiburg, on the role of forest education

Forestry isn’t a topic usually taught in schools, and despite its relevance to climate change mitigation and adaptation, the dilemmas of a forester might sometimes seem too intricate and technical to explain to a general audience. In Germany, however, since Education for Sustainable Development started being officially incorporated into school curricula in 2016, teachers received an incentive to bring forest-related topics into the classroom and take students on excursions to the forest.

To enable deeper discussions on the role of forests in climate protection, the forest education centre Stiftung WaldHaus Freiburg, in Germany’s Black Forest, installed a “junior” marteloscope site in cooperation with the European Forest Institute and the Integrate Network near its building in the city of Freiburg, where teachers and students can now see real-life examples of the economic and ecological values of trees. Almost 60 trees from eight species were mapped on the site, and a tablet app allows the visualisation and comparison of different attributes of each tree, giving visitors a concrete idea of how forestry decisions are made, and priorities established in forest management.

A week in the life of a marteloscopist

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.

Enable the enabler – when kids become knowledge MULTIPLIERS

„Base decision on facts, not on beliefs” – Kick-off Meeting of MULTIPLIERS project

by Gesche Schifferdecker and Rosa Castañeda

In school, science is often presented in an abstract way and without a context – but if we want to get young people interested, topics need to be relevant to their everyday life. This is the idea behind the H2020 project MULTIPLIERS – short for MULTIplayers Partnerships to ensure meaningful engagement wIth ScieEnce and ReSearch. In this project, scientists will bring real-life cases to students (from elementary school to secondary school), to look at specific “dilemma situations” from various perspectives.

These dilemma situations are explored in six different themes. The German theme is very up to date – it will explore the topic of “Pro–Con Vaccination” and is managed by MULTIPLIERS project coordinator University of Bonn. The University of Cyprus will focus on “Anti-microbial Resistance”, while Universitat Autonoma de Barcelona is investigating the theme “Air Pollution”. IREN SpA, an Italian company providing public services like energy, water, and heating, will handle the topic of Energy Efficiency.

You might be curious why European Forest Institute (EFI) is involved in this project? Well, of course MULTIPLIERS also tackles forest-related topics. In close collaboration with EFI colleagues, Umeå University is going to explore the dilemma of “Forest Use versus Forest Protection”. This topic is quite controversially discussed in Sweden – and not only there as we know. The debate is – like the debate around vaccination or air pollution – more emotional than based on evidence and thorough analysis.

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.

Mit Sechstklässlern ab in den Wald

Bäume ausmessen, ihr Alter bestimmen, Frosche und Blätter sammeln… Wie kann man Schüler*innen den Wald näher bringen? Alexander Held und Andreas Schuck haben mit einer sechsten Klasse einen Ausflug in das Mooswald Marteloskop in der Nähe von Freiburg gemacht. Hier kann man den unterhaltsamen Bericht einer Schülerin lesen.

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.
