The objective of this research was to study the distribution and social structure of the guanaco in the Calipuy National Reserve (RNC), La Libertad, Peru. 430 guanacos were reported with a slight downward trend (b = - 10.21), distributed in 114 km2. The adults were most numerous with 73.5% ± 9.8 (p<0.01) followed by juveniles and chulengos 16.1% ± 3.93 y 10.4 ± 5.9 respectively. The 72% of the population was found in family groups, 18% in herds and solitary accounted for 10%. The density was 5.7 individuals per km2. The population was mostly concentrated in the north, above 3000 m (p <0. 01), which is also the most heavily fortified, reaching 18.9 ± 8.97 guanacos/km2 and family groups mainly houses. The western zone under 3000 m and closer to the breeding area, was the lowest density 0.24 ± 0.24 guanacos/km2, and maintained primarily solitary and groups of males.
