In this investigation, we determined the diversity of archaeology, flora, vertebrates and the water availability of the village of Caray, district and province of Viru, region of La Libertad, Peru. The records were registered between 800 and 1500 m of altitude, during seven visits between January and March 2019. In ten transects of 25 x 10 m, we collected flora species and registered fauna respectively. There were 104 species of plants belonging to 39 families and 88 genera. Fourteen endemic species were registered, among them Browallia mionei [critically endangered (CR)], Lomanthus truxillensis, Lepidium pubescens, Austrocylindropuntia pachypus and Haageocereus pseudoversicolor [endangered (EN)], Heliotropium ferreyrae, Espostoa melanostele, Apodanthera ferreyrana and Dioscorea chancayensis [near threatened (NT)], and the remaining endemic species are located in the least concern (LC) category. Likewise, 54 species of vertebrates were registered: 2 amphibians, 7 reptiles, 44 birds and 1 mammal. Microlophus koepckeorum is endemic to Peru. In reference to the water resource, the samples were collected in the different stations in springs and in the Condornada waterfalls for the determination of water quality, for agricultural use and human consumption. In relation to the water quality, the study area has ideal characteristics for the preservation of natural resources because it presents the water resource available throughout the year, and preliminarily we can say that it has a pH close to neutral, water springs exempt of pollution; the volumes of water and the speed of flow, as well as its strong slope, are ideal conditions for the self-purification of the waters and to conserve the dissolved oxygen within the normal values for human consumption, agriculture, recreation and conservation of flora and fauna
