Euterpe edulis is considered a key species in the Atlantic Forest and is currently classified as vulnerable at a Brazilian list of threatened species, due to illegal extraction. In order to provide information for future projects of conservation, the present study characterized E. edulis reproductive phenology in four altitudes (30, 100, 200 and 400 m) in Salto Morato Natural Reserve – Guaraqueçaba/PR. In each altitude, five individuals were monthly monitored from March/2017 to February/2018. The intensity of phenophases was registered following the methodology proposed by Fournier. Flowering started at the lowest altitude (in September) and lasted for four months with a peak in November. At 200 m, flowering was present only in November. Immature fruits were present in the lowest altitude from December until February (with a peak in January) and, at 200 m, it only occurred in March. Green fruits were observed in three altitudes: at 30 m, it started in February and lasted for three months; at 100 m, it started with one month of delay (in March) and lasted for four months; at 200 m, this phenophase initiated with two months of delay (in April) and lasted also for three months. Mature fruits also presented differences as they initiated at different altitudes: it started in February at 30 m; in June at 100 m and in May at 200 m. There are differences in reproductive phenology of E. edulis throughout the gradient, which can be explained by differences in microclimate.
