This activity aims to sensitise students to the multitude of ecosystem services that forests provide to society as well as the challenges of meeting the needs of many different interest groups. The activity uses outdoor learning sites known as “marteloscopes”. Marteloscopes are delineated forest areas where data has been recorded for all standing trees. The data is made available to students via an innovative, easy-to-use, educational software (“I+ Trainer” software) running on mobile devices (tablets/mobile phones).

Given guidance, pupils can experience not only forests hands-on and observe trees closely. They can also gain an understanding of how and why forests are managed, why biodiversity in forest ecosystems is important, and how to come to solutions if forests should meet multiple demands such as providing wood for valuable wood products, be a place for recreation, and serve as a home for plants and animals.
