El Sira Communal Reserve  The El Sira Communal Reserve () is a protected area in Peru created on 23 June 2001 and located in three regions: the Huánuco Region (Puerto Inca Province), the Pasco Region (Oxapampa Province) and the Ucayali Region (Atalaya Province and Coronel Portillo Province). In 2010, UNESCO recognized the El Sira Communal Reserve as a Buffer Zone for the Oxapampa-Asháninka-Yánesha Biosphere Reserve. El Sira Communal Reserve is located in the east-central area of Peru, part of the Eastern Cordillera of the Andes, within the sub-Andean belt; between latitudes 09º 03' and 10º 22' and longitudes 74º 05' and 74º 48'. The SCR presents an altitudinal gradient from 130 to 2250 meters above sea level and is influenced by the basins of the Ucayali, Pachitea and Pichis rivers. The average annual temperature is 25.5 °C. Average monthly temperatures fluctuate between 24.6 °C and 25.8 °C. The lowest temperatures occur in the third quarter of the year and the highest in the last quarter. Extreme temperatures fluctuate between 15 °C (the lowest) and 33 °C (the highest), with 15 °C being the average oscillation between extreme maximum and minimum temperatures. The lower parts at less than 1000 masl are warm and rainy. The highlands that exceed 1000 masl present a climate that varies from semi-dry to very humid. The last and first trimester of each year have the highest rainfall. The dry season corresponds to the second and third trimesters, reaching 107 mm of precipitation in August. On the western flank of the mountain range there are phenomena that favor greater condensation of cloud bodies, unlike the east side (Ucayali basin). The values recorded for Puerto Bermúdez indicate an annual total of 3312.9 mm, unlike the values recorded for Pucallpa and Atalaya, which do not exceed records of 2500 mm per year. In the south of the reserve the landscape known as is less hot and humid, with average temperature values of 18.5 °C. The Reserve is located mainly in the upper or middle sectors of the tributaries of the Ucayali river basins (on the left bank), Pachitea and Pichis (on the right bank).
