Evaluation of the phytomass of the Pistacia lentiscus L. for rational exploitation of natural resources in a Peri-Urban forest of Algiers

In Algeria, the Pistacia lentiscus L. is widely used in different industries. Its uncontrolled exploitation threatens its sustainability. In the peri-urban forest of Bainem, the most important one in the capital Algiers and are witnessing degradation for several years by a strong exploitation for the benefit of small and medium-sized enterprises. This exploitation does not follow any sustainable management strategy. We measured the production of phytomass and essential oil in order to develop a rational management protocol for the exploitation of the lentisk pistachio tree. Ten productive facies are identified based on their floristic compositions, structures, and dynamic states: 4 matorrals and 6 types of reforestations. A significant variability of phytomass and essential oil production is noted between the different facies according to the density of the undergrowth. Exploitation classes are identified according to the facies and their respective productions. This protocol could be applied in the Mediterranean forests of North Africa.
