The natural diversity of the Cerro Andaraga Archaeological Site, Huaso district, Julcan province, La Libertad region, Peru is presented in a preliminary way. This region is the southern border of the AmotapeHuancabamba Andean zone, characterized by its endemisms, both flora and fauna species. There is archaeological evidence of early occupations in the rocky outcrops of the highlands, evidence of a holistic knowledge of the environment, its conservation and reasonable use. For the flora and fauna evaluations, transect tours were carried out through intensive search. In situ data were collected for exomorphological characteristics, life forms, common names and habitat. In the evaluation area, a deterioration was evidenced by the practice of agriculture without a zoning model. Archaeological constructions were found in a state of destruction and seven life forms were identified: 1) Plants with a bunch appearance, tillers and threadlike leaves, 2) Brevicaule plants with rosette leaves applied to the ground; 3) Plants on rocky outcrops; 4) Herbaceous and suffrutic plants; 5) Herbaceous, suffrutic and woody plants prostrateascending; 6) Upright shrubs and 7) Puya raimondii “cahua” stands. 15 families, 26 genera, 31 species of flora were preliminarily registered; eight of them are endemic: Jaltomata andagarae (CR), Coreopsis senaria (LC), Mniodes pulvinata (LC), Senecio collinus (LC), Calceolaria cajabambae (LC), Nasa ranunculifolia subsp. cymbopetala (LC), Dasyphyllum hystrix var. peruvianum (DD) and Senecio chiquianensis (NE). Stenocercus melanopygus (LC), an endemic lizard from Peru, was observed among the rocky area and shrubby plants. Nine resident bird species of this type of ecosystem were recorded, such as Metriopelia melanoptera (LC), Vanellus resplendes (LC), Phalcoboenus megalopterus (LC), Porphyrospiza alaudina (LC), Rhopospina fruticeti (LC), Zonotrichia capensis (LC), Asthenes pudibunda (LC), Ochthoeca leucophrys (LC) and Spinus magellanica (LC). This evidence implies the need to deepen research in this area and promote conservation activities and sustainable use of resources; as well as highlighting the archaeological site.
