The Spanish and Moroccan Pinsapo-fir forests have been recognized as areas of high biodiversity and endemism. Global Change, mainly throughout Land-use and Climate Changes can endanger this flora. It is necessary to know stand structure and biodiversity of these relict forests in order to apply conservation strategies. Several structural features, biodiversity and environmental variables were assessed in the wider Pinsapofir forests. Biodiversity values were higher on Moroccan stands while maximum treesize class variability and stand structure diversity was yielded in an old-growth Spanish stand. Mean tree-ring width showed a steady pattern on Moroccan sands, while Spanish forests yielded a higher variance and sudden growth decline over the last third of the XX century. Our results suggest that the preservation of minor perturbation regimen by local populations would also help to preserve the whole biodiversity of this relict habitat.
