The objective of this work was to determine the diversity of palm trees in three regions of the lower Amazon (Loreto, Ucayali and Madre de Dios). The study was carried out during the Project developed in the years 2004-2013, within the framework of the Palms project. A total of 354 5 × 100 m transects were inventoried, totaling 88.50 hectares of evaluated area in the three regions. In the Loreto region, 239 transects were carried out, in Ucayali 38 transects and Madre de Dios 77 transects. A total of 97 species and 6 morphotypes were recorded. In Loreto, Oenocarpus bataua “hungurahui” was the most abundant with 28,898 ind. (10 % total of the ind.), in Ucayali Lepidocaryum tenue “irapay” with 14.379 ind. (20% of the total ind.) and in Madre de Dios Geonoma deversa “palmiche” with 5,743 individuals with the (20% of the total individuals). Loreto was the region with the greatest diversity of species with 3.601, Ucayali with 3.061 and Madre de Dios with 2.839. Between Loreto and Ucayali there was a similarity of 73% and between Ucayali and Madre de Dios 47% and between Loreto and Madre de Dios 35%. Our results show that the greatest abundance and diversity of palm species in the lower part of the Peruvian Amazon is found in the Loreto region, followed by Madre de Dios and Ucayali.
