According to Holdrigde, the life zones were identified into the process for Economic Ecological Zoning (ZEE) of Trujillo Province, La Libertad Region, Peru. The variety of climate conditions, soils and geomorphology have given rise to different life zones, which are characterized by the presence of a typical vegetation in each of them. In this sense, eight life zones were identified, located in the different altitudinal floors, whose qualification, from the point of view of the Holdridge system, is the following: Desiccated desert-Subtropical (dd-S), Perarid desert-Subtropical Lower Montane (dpMBS), Desert scrub-Subtropical Lower Montane (md-MBS), Superarid desert-Premontane Tropical (ds-PT), Desert scrub-Tropical Lower Montane (md-MBT), Perarid desert-Tropical Premontane (dp-PT), Desert scrub-Tropical Premontane (md-PT), Thorn scrub-Tropical Premontane (mte-PT), Thorn steppe-Tropical Lower Montane (ee-MBT). In the coastal area (Desiccated desert-Subtropical (dd-S)) afforestation is mainly carried out with Tamarix gallica L. (Tamaricaceae) "tamarix" and Acacia horrida (L.) Willd. (Fabaceae) "huaranguillo". On the eastern border with the province of Otuzco (Thorn steppe-Tropical Lower Montane (ee-MBT)) begins the afforestation with Eucalyptus globulus Labill "eucalyptus" and other species that allow to conserve areas for reforestation and/ or agricultural use, and finally through the Economic Ecological Zoning, it allows to reach the integration of specific studies in the establishment of the potential of the life zones of the Trujillo Province.
