ResumoPuya raimondiiHarms is an endemic plant with a distribution in the Peruvian and bolivian andes between the 3500 and 4800 msnm in the populations known as stands; among its known distribution, this covers the department of Lima; however little is known about its geographical and population distribution in the surroundings of the Huarochiri district, Lima, Peru.The population study was performed at the stage of flowering and fruiting of P. raimondii from 2016 to 2017.It determined the distribution, size and population density, in addition to the age of the individuals surveyed.In total there are 11600 individuals distributed in five stands between 3900 and 4550 msnm.The population density was between 20 and 50 -1 ind•ha .The Huajlasana stands 47% of the total, followed by Huaquinanchi (Sector I and II) with 34%, Pacchapuquio with 15% and Cerro piño with 4%.The largest population consisted of adult plants in flowering and/or fruiting stage (46%), young plants (39%) and tender plants smaller than 50 cm (12%).Finally, we observed that the main threat of Huarochiri stands is close grazing, which causes the plant to be cut to avoid gaining grass trapped between thorny leaves.
