Marteloscopes are a French innovation that were developed in the late 1980s as a tool for training professionals in silviculture and for understanding key habitat elements and structures in forests. They were created in response to a need for more effective in-forest training methods and for a way to integrate conservation goals into forest management practices. The first Marteloscope was established in 1988 in the French National Forest of Tronçais and the concept has since spread to other countries in Europe and beyond. Marteloscopes are now used in a variety of settings, including research institutions, universities, and forestry companies, to provide practical training and to facilitate the integration of economic and conservation goals in forest management.
