Abstract Resin is a renewable forest resource that can increase the economic value of some forests in rural areas. production associated with climatic conditions. However, its impact on trees’ growth remains unclear. Here, we studied radial six Portuguese Pinus pinaster had been resin tapped for 5–7 years along latitudinal and gradient to understand whether tapping affects tree growth, how it affected by climate, stand traits. Tree-ring width ( TRW ) untapped trunk sides was compared before during period. decreased three youngest populations (< 30 years), no changes older (> 40 while increased after harvesting began oldest 55 years). Annual resin-tapping RTI ), calculated as ratio between 5-year average tapping, below above 1 younger stands, respectively. Among characteristics across sites, negatively correlated competition positively , cambial age, height. Climatic conditions minor role response tapping. Our main conclusion effect extraction age-dependent. results encourage co-production wood maritime pine stands over old where negligible.
