Recovery of Pilgerodendron uviferum (D. Don) Florin forest after antropogenic disturbance in the Valdivian Costal Range, Chile

The loss and decline of one ecosystem can be triggered by continuous changes in structure made by frequent and/or severe disturbances. Therefore we quantify the structural losses and the posteriori recovery after man-made disturbances of two fragments of P. uviferum in the Reserva Nacional Valdivia...
