Marteloscope data and marked trees according to systemic and traditional thinning regimes by raters and experts (Appennino Pistoiese, Italy)

Marteloscopes are training areas where forestry students and practitioners mark trees according to silvicultural objectives. This dataset comprises the trees selected for harvesting in a marteloscope according to different alternatives: systemic, traditional, crown and low thinning. Tree records on species, diameter and total height are also provided. Raters were classified according to socio-demographic variables including binary gender (female and male), age class (more or less than 40 years) and educational background (forester vs. non-forester). A total of 24 raters participated in the marking procedure.
