Study of the resilience parameters of cork oak after fire in north-western Algeria

Abstract

ABSTRACT The periodic exploitation of the cork coinciding with the wildfire reinforces the vulnerability of the trees by affecting their vigour and their productive potential. Results showed that trees lightly affected by fire (recoverable) manage to overcome the disturbance without major impact on regeneration and growth variables (IR = 3.80, growth = 2.04mm/year; thickness = 14.81mm; volumetric density = 283,59 kg/m3; IQ = 8,56). Paradoxically, standing dead trees record a very low resilience (IR = 1.23; growth = 0.26mm/year; thickness = 1.99mm; volumetric density = 347.02 kg/m3 and IQ = 1.50).
