    Forests are one of the most valuable ecosystems in the world. The Native Forest Elementary, is one that maintains its original structure. Yagual forests are vital resources for the conservation of biodiversity and hydrological functions. In the province of Bolivar and exclusively in the canton Guaranda no current statistical records of the amount of native forests still exist. An inventory and characterization allows to know the variation of the forest in different strata or ecosystems. Through this research is to contribute to an information base silvocultural of different species existing native forest and shrub in this forest. The objectives in this research were: Identify tree and shrub species present in the stand of Yagual. To determine the morphological characteristics that present each of the species. Conduct a study of forest species Dasonométrico. This research was conducted in the field of Tundapamba, belonging to the canton Chimborazo, Bolivar Province, formed three layers of a dimension of 20 m x 60 m each. The main findings are: When making an inventory of the trees and shrubs that make up the native forest stands of yagual, identified 5 species of trees, in which stands the Polylepis hirsuta (paper tree), and 22 species of shrubs among which Baccharis latifodia (white ragwort). The average total height of tree species in the stand under study was 5.2 m, with the largest species Polylepis hirsuta height with 5.1 m. The variable average total height of shrubs was 1.8 m, was epitomized by the species Polylepis sp with 3.3 m. The highest average of the variable stem diameter and basal area showed the same tree species Eugenia sp with 18.7 cm and 2.9 cm 2 in their respective order. The largest stem diameter at the shrub species recorded Myrcine sp with 16.2 cm sp. The largest relative density stands shrub species presented him with an index of 2.1, versus only tree species present a value of 1.6. The most representative plant species found in stands that had medicinal properties were Arrayán, pumin, grind, matico, and caglán
