Resumen: Phenology is one of the main ecological aspects when it comes to silvicultural and agroforestry management. However, phenological knowledge of forest species is still scarce and fragmented, mainly in the tropics. Cinchona pubescens Vahl. presents limited phenological information, so the objective was to evaluate the phenology of the species C. pubescens Vahl. in two forest ecosystems (silvopastoral system and secondary forest) located in Pucará Alto, Intag area, Imbabura, for the period April 2018 - May 2020. Individuals of C. pubescens were characterized and selected according to phenotypic characteristics. Phenological monitoring was carried out with Fournier’s semiqualitative method. The average index (PI) and weighted percentage of phenophases were calculated. The foliation was present throughout the year in an intense massiveness in both ecosystems. Flowering occurred once a year, in the period January-May in both ecosystems with an intense massiveness. Fructifcation for silvopastoral system occurred intensely in the period August-November with its maximum in October and for secondary forest with medium massivity in the period September-December with its maximum in November.

Palabras clave: foliation, fowering, fruiting, phenophases.
