The research was conducted by Rafael Mora, Jorge Martínez-Moreno and Miquel Roy from the Centre for the Study of Prehistoric Archaeological Heritage, Universitat Autònoma de Barcelona (CEPAP-UAB), in collaboration with Ethel Allué, from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and the Rovira i Virgili University (URV), and Alfonso Benito-Calvo, from the National Centre for Research on Human Evolution (CENIEH). It was published in the journal Review of Palaecobotany and Palynology.

Researchers analysed a total of more than 1,200 carbon fragments from the hearths of some 15 archaeological units. "The anthracological analysis of such a compound used during so many years as is Cova Gran, together with data from other sites in the region, indicates a hegemonic presence of Scots pine in the northeast of the Iberian Peninsula and demonstrates that despite the occurrence of extreme climate changes, the montane coniferous forests cover was continuous," says IPHES researcher Ethel Allué.
