The planting of three forest species in Andean scrubland in southern Ecuador was experienced in two areas: one carrying out pure planting, planting 20 plants per block species, with three repetitions; and a second area with mixed plantation 20 mixed individuals in each block. Survival, mortality, average growth and annual periodic increase in diameter and height were calculated. Survival at 3 years: Cedrela montana in 37 % pure plantation and mixed 10 %, Jacaranda mimosifolia pure plantation 58 % and mixed 55 % and Lafoensia acuminata pure plantation 93 % and mixed 75 %. Annual mortality: Cedrela montana pure plantation 33 % and mixed 77 %, Jacaranda mimosifolia pure plantation 18 % and mixed 20 % and Lafoensia acuminata pure plantation 2 % and mixed 10 %. Growth in three years: Cedrela montana pure plantation diameter 0,18 cm and height 11,12 cm; mixed plantation diameter 0,36 cm and height 3,08 cm, Jacaranda mimosifolia pure plantation diameter 0,05 cm and height 0,38 cm; mixed plantation diameter - 0,003 cm and height 8,34 cm, Lafoensia acuminata pure plantation diameter 0,08 cm and height 21,95 cm; mixed plantation diameter 0,05 cm and height 4,83 cm. There is decrease in height in Cedrela montana and Jacaranda mimosifolia, this responds to the apical death of some individuals. There are differences in survival and growth between areas, due to the species used and biophysical factors of the sites.
