RESPROUTING OF QUERCUS-SUBER IN NE SPAIN AFTER FIRE

Many Mediterranean species have evolved strategies that allow them to survive periodic wildfires. Quercus suber trees resprout after fire, s ome from stem buds and others from basal buds only. In the former case the canopy recovers quickly. In the latter case the stem dies but the tree survives and regrows from basal sprouts. The probability of stem death and the degree of height recovery were studied after a fire in a Q. suber forest in NE Spain using logistic regression analysis. The results suggest that most trees survive after fire; the probability of stem death is negatively related to tree diameter; and recovery is po sitively related to tree diameter and to bark thickness. Implication f or management and conservation of cork-oak forests are discussed.
