In methodologies such as RAINFOR for permanent plots, one of the most relevant considerations is "location," leading to their installation primarily in protected natural areas. This study characterized the high-terrace Brazil nut forest at the Finca Las Piedras research center, a private conservation area in Madre de Dios, Peru. The permanent plot "FLP-01" was established as part of ForestPlot.net, using RAINFOR. FLP-01 had 549 individuals of 173 species, in 106 genera and 48 families; the most important species were *Bertholletia excelsa*, *Siparuna decipiens*, and *Protium altissimum*. In horizontal structure, 67.2% of individuals were between 10-19.9 cm in diameter, and vertically, 76.5% were found between 10-20 m in height. Floristic diversity was high: Shannon (4.79), Fisher's alpha (87.06), and Chao 1 estimated 313 possible species. It is concluded that FLP-01 has high floristic diversity, but is not taxonomically similar to other more studied areas (Manu and Tambopata); factors such as soil type, geographic location, and phytosociology (sympatry) could influence this.
