Silvicultural characterization of single-species stands of black pine in Catalonia (Spain)
AbstractThis study presents a silvogenetic typology of single-species stands of Pinus nigra in Catalonia (NE of Spain) based on the information supplied by the Second National Forest Inventory. Results of factor analysis applied to dendrometric variables show nine different stand types, identified mainly from variables related to diameter distribution and stand stocking. The character of uneven-aged stands, present in five of the groups though with different features, was analyzed using a truncated Weibull distribution. The typology, which is managed by computing regeneration levels and diametric classes, encompasses different developmental stages and allows the diagnosis of compromised situations in terms of stand persistence caused by low or high stocking.
