The Marteloscope of Arronategi: the new outdoor classroom in the forest of Bermeo

The LIFE URBASO project is demonstrating nature-based solutions to ensure the quantity and quality of water for human consumption. To achieve this, it aims to promote close-to-nature forest management models to optimize the interactions between forests and water. In order to showcase and encourage these forestry models, NEIKER has established a Marteloscope in the Arronategi public forest (MUP 47), owned by the Bermeo City Council. 

A Marteloscope is a “forest classroom” where the outcomes of different forest management models can be analyzed, considering factors such as timber production, biodiversity conservation, carbon sequestration, recreation, or fire protection. In the designated Marteloscope plot, all trees are numbered, georeferenced, and measured (diameter, height, and tree-related microhabitats), allowing for an assessment of their economic and ecological value. 

Based on this information, selective marking simulations can be conducted, allowing the in situ evaluation of their impact on biodiversity and economic value. The goal of these exercises is to enhance understanding of the complexity involved in decision-making for multifunctional forest management, which must balance various objectives, including forest stand sustainability and improvement, timber production, biodiversity conservation, carbon sequestration, regeneration, and fire protection. 

The Arronategi Marteloscope has been incorporated into the Integrate+ network, managed by the European Forest Institute (EFI).
