Summary

Every tree stem was mapped in a area ca.1. Ha wide birch forest in Urkiola Natural Park (Bizkaia-Araba). For alive stems birch was the main species, followed by beech and tree heath and pedunculate oak. Dead stems were dominated by tree heath, pine, birch and oak. Diameter distribution was of normal type for birch and negative exponential in oak and beech. Spatial pattern analysis showed that beech with similar DBH tended to be aggregated, while this pattern was random for birch. Some hypothesis are formulated in order to understand history and proccesses occuring in this plot.
