AB Background: How environmental factors affect forest regeneration is relevant forsystems that depend partially or fully on natural regeneration.Objective: P. pinaster post-disturbance regeneration and its relationship toenvironmental factors was studied in five P. pinaster forest populations of centralSpain. We expected that 1) different harvesting methods or wildfire would promotenatural regeneration in all populations, but with local and regional variations; 2)alternatively, different site-dependent stand factors would affect natural regeneration,although generalized climate effects would be seen. Analysis of variance andmultivariate analysis were used to test differences, to classify ecological variations andto search for the most important factors affecting regeneration.Results: The results suggest that the recovery of P. pinaster forest in burnt stands, andstand replacement in harvested stands can be achieved soon after disturbance if climaticconditions and other local-site factors (e.g. soil and overstorey structure in harvestedstands, cone bank in burnt stands) make the stand suitable for natural regeneration.Heterogeneous regeneration can be expected in all cases. The time of precipitationstrongly influenced seedling density and successive regeneration development stages.Edaphic properties combined with water availability from precipitation can seriouslylimit the natural establishment of P. pinaster in xeric systems or during years of intensedrought. Although many factors contribute to high variability natural regeneration wasvery effective (successful) in P. pinaster forests, which contributes to the generalizationthat natural regeneration is a viable forestry option in many forest types.
