| High-intensity anthropogenic disturbances are usual and frequent in European forests. Different studies have shown that, after anthropogenic disturbances, species restitution along succession is variable and hence not easily predictable. Therefore, long-term demographic studies are needed to better understand this process. To survey the regeneration dynamic of a birch-beech temperate forest, a permanent fenced plot of 2.5 Ha was established in a secondary young forest stand, located in Urkiola Natural Park (Basque Country), and dominated by birch (Betula celtiberica), interspersed with beech (Fagus sylvatica), pedunculate oak (Quercus robur) and Pyrenean oak (Q. pyrenaica). The aim of this study was to determine the shift in dominance of the tree species present in the experimental plot. In 1999, every individual trees higher than 1,4 m (or with stem diameter larger than 2 cm) was mapped by its XY coordinates in the plot, and diameter at breast height (DBH) recorded. This sampling was repeated twice, in 2005 and 2010. Annual mortality rate was catastrophic (>5% yr-1) for pedunculate oak between 1999 and 2005, while declined slightly between 2005 and 2010 (>3% yr-1). Furthermore, birch, Pyrenean oak and beech showed similar trends in mortality through the whole study period, moderate for birch and Pyrenean oak and low for beech. Adult spatial pattern changed for birch and beech but not for pedunculate oak. | |
