Avalia？？o da Produ？？o Primária Líquida em Povoamentos Puros e Mistos de Quercus pyrenaica Willd. e Pinus pinaster L. no Distrito de Vila Real

with this study we quantified net primary production (npp) of pinus pinaster and quercus pyrenaica pure and mixed stands. this evaluation was based on sampling plots from the last national forest inventory and is exclusively located in the district of vila real. results from this study allowed the first npp figures for these kind of forest stands, and thus the quantification of these ecosystems potential for sequestering carbon. pure and mixed stands npp figures were compared. the results pointed to a greater production potential of mixed stands, though not statistically significant.
