Adapting forests to climate change: methods, tools, and projects

What does climate change adaptation look like in Southern France? Is there anything we – in Central Europe – can learn from our colleagues in the South? Is risk management an issue there and do forest risk experts know the European Forest Risk Facility?

These were the questions – among others – that I had before attending the international symposium “Adapting forests to climate change: methods, tools, and projects” on 19-20 November 2019 in Toulouse, France.

The symposium was organized by the FORECCAST project, partially funded through the EU LIFE project,  aiming to provide Haut-Languedoc Regional Nature Park producers and forest managers with means to build a forest management strategy that takes into account the impact of climate change. Goal of the project is to raise awareness of the challenges posed by global change among stakeholders, elected representatives and the general public within that region.

The potential of recovering degraded pine forests

by Alessandra Lagomarsino

Did you know that worldwide forests each year absorb 30% of the CO2 emitted globally by fossil fuels and are huge carbon sinks, thus contributing to climate change mitigation and storing carbon in different pools (i.e., biomass, soil, dead organic matter, or litter)? However, when a forest is degraded with many dead, fallen and damaged trees, it does not remove enough CO2 from the atmosphere to compensate the emissions due to the decomposition of dead trees and soil organic matter.

Integrating nature protection into forest management the Danish way

Did you know that Denmark has a relatively low forest cover of 14 percent, but nonetheless has great ambitions regarding the ecosystem services they wish those forests to provide? All the more reason to understand more about how they integrate different forest functions into forest management.

I had the chance to find out more about Danish sustainable forest management – or Close-to-Nature Silviculture, as the Danes would call their particular brand – when I participated in the most recent meeting of the European Network INTEGRATE , which is currently chaired by the Danish Nature Agency.

Managing forests as functional complex networks

Written by Marco Mina

Although a variety of forest management approaches to cope with climate change have been proposed worldwide, what has been missing so far is a way to integrate them at appropriate scales, particularly at landscape level, and to put a primary focus on enhancing forest resilience in the Anthropocene.

I suppose that readers of the Resilience blog do not need a long introduction on the myriad of threats that the climatic and global changes pose to forest ecosystems. Mutating climate, drought, unexpected extreme disturbances, sudden shifts in socio-economic conditions but also forest fragmentation, pollution and new pest and diseases are making long-term forest planning more and more difficult. Scientists are still debating on the topic, but many are convinced that we entered in a new geological era: the Anthropocene. How can we therefore manage our forests so that they are more resilient to the high level of uncertainties that characterize this new era?

New Fences in Ireland?

No, not the border fence between Ireland and Northern Ireland, no.

In this blog, we are discussing tree species composition, forest adaptation and conversion towards more resilient forests! Deer management in silviculture is one of the crucial factors to consider, just like enough light for the seedlings and site conditions. And here are the fencing news from Ireland, I quote from the Irish newspaper “Independant”.

“New deer fencing grant among measures to support biodiversity of Irish forests: Minister of State at the Department of Agriculture, Andrew Doyle today announced the opening of three new support measures to support biodiversity of Irish forests. A new scheme to support  ‘Continuous Cover Forestry’, (CCF), which allows for the production of commercial timber while retaining forest cover at all times. Continuous Cover Forestry (CCF) is an alternative forest management approach where the forest canopy is maintained at one or more levels without clearfelling. The distinctive element of CCF is the avoidance of clearfelling areas greater than 0.25 ha or more than two tree heights wide without the retention of some mature trees. These systems are generally associated with natural regeneration but natural regeneration can be supplemented by planting if required.

Participation and Integration – Forest Management in Slovenia

Simon Poljanšek, you are the new Slovenian national focal point for the European Network INTEGRATE. Would you please introduce yourself?

Simon Poljansek
Simon Poljansek

Growing up on a small farm, surrounded by forest and animals, it was easy for me to connect with nature and outdoor activities, road cycling, photography, animals, and becoming a family man. An obvious choice was to study at the University of Ljubljana Biotechnical Faculty, Department for Forestry and Renewable Forest Resources. I successfully finished my studies there with a rewarded diploma thesis on the analysis of the amount and structure of deadwood in Slovenian forests. My education continued with a doctoral thesis on dendrochronological investigation of Black pine (Pinus nigra Arnold) in the Balkan Peninsula, which I conducted at the Slovenian Forestry Institute. I used different tree-ring parameters (widths, density and stable isotopes) to investigate the influence of climate (temperature, sunshine, precipitation, river hydrology) or other extreme events (forest fires) on trees, growing in various environments from mountainous sites to urban surroundings.
What are you currently working on in the Slovenian Ministry of Agriculture, Forestry and Food?
The knowledge obtained on this path I described above is now used for monitoring contents and procedures of forest management plans, and assessing forest resources. Furthermore, I use my scientific experience to review targeted research projects, and to collaborate with my team in the development of the “LULUCF” national forestry accounting plan. Finally, a crucial part of my work is to cooperate in different governmental and other institutional associations with the aim of developing system solutions for the sustainable development of forests ecosystems, resilience and biodiversity, alongside with environmental, production and social forests functions.

Veranstaltung "Waldbau und Waldbewirtschaftung im Klimawandel"

Neue Instrumente für den Waldbesitz in Nordrhein-Westfalen

Angesichts der Veränderungen, die sich aus Klimawandel, Digitalisierung und neuen gesellschaftlichen Ansprüchen ergeben, benötigt die Waldbewirtschaftung effektive IT-unterstützte Management-Instrumente. Im Rahmen der Veranstaltung “Waldbau und Waldbewirtschaftung im Klimawandel” stellt das Ministerium für Umwelt, Landwirtschaft, Natur- und Verbraucherschutz des Landes Nordrhein-Westfalen (MULNV) am Freitag, den 7. Dezember 2018 in Düsseldorf neue Hilfestellungen des Landes vor, mit denen der Waldbesitz auf die Herausforderungen reagieren kann: das Waldbaukonzept NRW, die landesweite forstliche Standortkarte und das neue Internetportal Waldinfo.NRW.

Discussions on impacts of silvicultural interventions: the Falkenberg Marteloscope

from Andreas Schuck and Loic Duchamp
In the beautiful autumn forest in Vosges du Nord – Forêt de Bitche, France, we organized a training session with 44 foresters from public and private forests on 18th and 19th of October 2018. The Marteloscope ‘Falkenberg’ was set up in the course of European Forest Institute’s Integrate+ project, and it is located on state forest land in a Nature Reserve, in the heart of the Northern Vosges Regional Nature Park (French part of the Transboundary Biosphere Reserve Vosges du Nord–Pfälzerwald). 60%, or 76.283 ha of the park are covered by forest, composed of 58% broadleaves and 42% conifers.
One main conservation objective in that nature reserve is to increase forest naturalness. This is achieved by designating strictly protected areas and preserving or restoring forest composition and potential habitats in managed forests.

The symmetry of competition: does the battle take place above or below our feet?

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.

Close-To-Nature Forestry across Europe

A short report on the annual Pro Silva Europa meeting in Weimar, Germany

Pro Silva is a European federation of professional foresters across 24 European countries (and more recently in New England, USA) who advocate and promote Pro Silva Close to Nature Forest Management Principles as an alternative to age-class forestry to create and maintain resilient forest ecosystems. Increasing forest resilience was also the motivation to create Pro Silva 29 years ago.
This year, the annual meeting was planned and prepared by ANW Deutschland and Pro Silva Europa. It was operationally hosted by ANW Thuringia and the state forest administration of Thuringia in and around the city of Weimar on 20-23 June 2018. The Pro Silva Program addressed topics such as forest conversion from age-class to continuous-cover forestry, re-introduction of silver fir (and other climate-change-relevant tree species) and the ungulate-silviculture challenge of converting European forests to more biodiverse, stable and resilient forests.
