Privately Protected Areas (PPA) are one of the conservation mechanisms managed by private citizens that have acquired more prominence in local conservation scenarios in recent years. In this study we evaluated the effectiveness of four (PPA) managed by local communities (CC). The Composite Effectiveness Index (CEI) was applied to determine the effectiveness of design, ecological integrity, and management. The results show management systems with medium effectiveness, three of the four PPA evaluated (Copallín, Huaylla Belén-Colcamar and Tilacancha) report effective design. The protected altitudinal ranges are between 2500 and 3500 m.a.s.l., with an average surface representativeness index of 4.55% with respect to the area conserved in the PPA category for the department of Amazonas. The evaluation of ecological integrity indicates that the PPA present lower transformed surface (TS) (0-10%) and higher TS in their surrounding areas, especially in the Tilacancha PPA (13.37% TS in a buffer of 1.5 km). The weighted sum of the individual indices results in composite effectiveness indices from highest to lowest for the Copallín PPA (2.22), Hierba Buena Allpayacku (1.82), Huaylla Belen Colcamar (1.81) and Tilacancha (1.56).
