    In Ecuador there is little information on the forestry knowledge of native species that allow having technical and scientific tools to use them within reforestation and ecological restoration plans. For these reasons, it is important to carry out different technical activities such as phenological studies to design calendars, especially for the collection of seeds. Under this background, the present study was developed whose objective was to evaluate the occurrence of the phenological phases of 10 forest species and their relationship with the environmental variables of temperature precipitation and heliophany. The native arboreal species studied were: Clethra fimbriata (Cletra), Escallonia myrtilloides (Chachaco), Ilex rupícola (Ilex), Myrcianthes rhopaloides (Arrayan), Myrsine dependens (Myrsine), Oreocallis grandiflora (Gañal), Oreopanax andreanus (Pumamaqui rojo), Oreopanax avicenniifolius (Pumamaqui blanco), Vallea estipularis (Sacha capulí), y Weinmannia fagaroides (Sarar). These are found in the forest of Granja Nero, belonging to the University of Cuenca. Methodologically, six individuals were selected for each species, with good phenotypic characteristics. The monitoring of these species was carried out every 15 days for a period of 26 months. In addition, the environmental variables of precipitation, temperature and heliofania were correlated with the phenological stages flowering and fruiting. Of the ten species Clethra fimbriata (Cletra), Escallonia myrtilloides (Chachaco), Oreopanax andreanus (Red Pumamaqui) did not show flowering and fruiting. However, those who did experience these phases did so in different months and with different intensity. The phenological phases of flowering and fructification of most of the species showed a greater correlation with heliophany. It was also observed that, during the study period, the flowering and fruiting of the ten forest species highlight their fertility
