The last 14 years of survey and research in the area of Aigüestortes i Estany de Sant Maurici National Park, located in southern central Pyrenees, shows an early human presence related to the development of an agro-pastoral economic system. The collected evidences proceed from little cave and rock shelter sites, like Cova del Sardo and Obagues de Ratera, although in the nearby valleys of Andorra where some open-air sites are recorded at Juberri and Madriu valley, mainly. Combined with archaeological research, that integrate surveys, site sampling and diggings, a new approach based on pit sampling research program for ancient landscapes reconstruction have been implemented. It works out soils micromorphology, pedoanthracology, pollen and phytoliths analysis. One of these test pits was 570 m away from Cova del Sardo, with human occupations over quite all the Neolithic period from 5609 to 2495 years cal BC. In this work we present the pit profile study, including the paleosol dated between 5200 and 4940 cal BC. The main results indicates that the first firing of primigenius sub-alpine button valley forest may be associated to early Neolithic occupation of Pyrenean Mountains, around 5000 years cal BC. We present the obtained data from the test pit, that provided information of human impact in the environment at the area beside Cova del Sardo, as well as archeobotanical data from the site. This microscale perspective complements the more general paleoecological data obtained in a nearby lacustrine core sited at 4.5 km, in the same valley: Estany Redó d'Aigüestortes. Finally, we discussed when neolithisation process arrive to mountains areas and how this first agro-pastoral societies impacts on forests and ecosystems, using burning for management, open the landscape and pastures formation or cultivation practices.
