• Abstract:

  The study area is located in the town of Espinosa, municipality of Arteaga, Mich. The proposed objectives were: Identify impact factors in the populations of Brosimum alicastrum, evaluate the natural regeneration established and the growth of the seedlings, determine the value indices of importance, significance and diversity of the species. With the Google Earth System and GPS, the populations of the species were located, sampling units of 1000 m2 were located, the DN, height, CM were measured for trees greater than 10 cm, the Basal Area and Volume were calculated. in m3/ha; using the Muller-Dombois and Ellemberg method, the density, dominance, frequency and value of importance were derived; and with the Margalef method the diversity index was obtained. A GIS was created, in which 13 populations of Brosimum were located. The main results refer to the average DN of 41.8 cm, height 19.4 m, crown width 4.8 m, AB/ha 14.9 m2, volume/ha 159.9 m3, health and vigor 85%; the fruits are eaten by wild and domestic animals, those that manage to germinate if they are not in a protected environment are also consumed in the seedling state.
