Regeneration of Quercus Forest after Fire Under the Influence of Ecological and Environmental Parameters

Abstract

Fires are one of the major disruptive factors for all forest biomass. The study was carried out at the level of the Algerian Northeast region, where forest sites of Souk-Ahras are remarkably materialized by the species: Quercus suber and Quercus canariensis. The regeneration problem analysed after fire took into account the effects of natural environmental parameters, namely temporality, frequency of individuals and topographical parameters such as exposure, slope and altitude. The results show a very small and relative change. However, the cumulative actions of these latter must be checked by the intensity of the fires, by the energy and the kinetics of combustion in order to be able to pronounce on the possible temporality to the regeneration. Thus, it turns out that the frequency parameter depends closely on the storage and the arrangement of individuals, as this, could give the necessary time for cells to no longer have the ability to function for regeneration. For the topography parameter, regeneration is observed from the altitude 800 m. And, by combining the exposure sub parameter, we concluded that the regenerated parts benefited from better radiation.
