The objective of this study it was to determine the impact of the reforestation program executed by CONAFOR in the Forest Management Unit 2404, to which it was calculated the difference in the quantity of biomass between the year 2000 to 2015 (the year 2010 was analyzed as intermediate) in order to determine the impact of the reforestation program executed. To achieve this purpose, images Landsat 5 TM for years 2000 and 2010 and Landsat 8 OLI for year 2015 were processed. In these images, the traditional NDVI was generated (bands red and infrared of spectrum). Later the quantity of biomass was estimated using allometric equations, in which it was used the information of 44 conglomerates from the National Forest Inventory. With these data, one linear and two nonlinear models (exponential and polinomial of second order) were tested for each year, and in the three cases the polinomial model was selected. To validate the results, the Pearson correlation coefficient was calculated (0.69, 0.65 y 0.64, para 2000, 2010 and 2015, respectively), which indicates a high correlation of the data obtained. With the application of the model in the mosaics for three periods, obtained that from 2000 to 2015 there was a significant increase both in the quantity of biomass and in the area with vegetation. We conclude that the reforestation program has had a positive impact in the study area.
