Araucaria angustifolia (Bertol.) O. Kuntze., also known as brazilian-pine, is a forest native species from Brazil. A. angustifolia is more vulnerable to global climate change, considering it is living in cold and humid mountain regions from southern and southeastern Brazil. Among the native Brazilian forest species, it presents one of the greatest growth and genetic gain potential. It shows excellent wood quality and can still be used in human and animal food, presenting great economic, social and environmental value. In order to determine current distribution of the species and better know its habitat, we worked in the regions representing the borders of natural occurrence, identifying populations and getting trees altitude and geographycal position. Field information along with secondary data from the Environmental Information Center (CRIA) were used to map current distribution of brazilian-pine and to project the distribution in the next decades, with the projection of future climate scenarios. Mapping studies of ecological niches in present and future climate scenarios characterizing the environments in which they are living is essential for a better understanding of the risks of species extinction and which mitigating measures could be adequate to reduce the impacts of global climate change on species, thus contributing to the conservation and knowledge of this important species.
