A Marteloscope exercise being carried out in Belgium by Silvester Boonen/EFI. P.C- Raghav/EFI
This article presents the Integrate+ marteloscope concept as a practical, field-based training and decision-support tool that helps foresters, conservationists, and other stakeholders better understand trade-offs between biodiversity conservation and forest production through hands-on tree selection exercises.
The article introduces marteloscopes as standardized forest plots where every tree is mapped, measured, and described in detail, including economic value and biodiversity features such as tree-related microhabitats. Developed and expanded within the Integrate+ network, marteloscopes are designed as learning and dialogue tools rather than experimental research plots.
Participants simulate tree-selection decisions directly in the forest, supported by digital tools that instantly calculate impacts on timber value, stand structure, and biodiversity indicators. By making consequences visible, marteloscopes foster shared understanding among different professional groups and encourage discussion about multifunctional forest management.
The paper emphasizes that “seeing” the outcomes of management choices helps bridge gaps between theory and practice, and between stakeholder perspectives. Marteloscopes are therefore positioned as an effective approach for capacity building, knowledge exchange, and improved implementation of integrative forest management across Europe.
