Estudio demográfico de miconia bracteolata (Bonpl.) Dc. y Tibouchina lepidota (Bonpl) Baill. en el bosque Montano Alto, de la parroquia Baquerizo Moreno, cantón Píllaro, provincia de Tungurahua.

Abstract

In this research study, a demographic revision of Miconia bracteolata and Tibouchina lepidota in the Montano Alto forest, Baquerizo Moreno parish, province of Tungurahua was carried out. The methodology used consisted of a sampling, starting with a tour of the buffer zone of Montano Alto forest to determine the best points to establish 10 plots of 10x10 m, which made up a sample area of 1000 square meters; plots where the geographic coordinates were taken and with the help of pegs and stakes were delimited trying to represent most of the population of the area, we started to take data on the number of individuals of each species, their height in centimeters, diameter at breast height (DBH) and the phenological stage in which they were found being these: seedlings, juvenile seedlings or adult seedlings; with the recorded data, the importance value index (IVI) and the Simpson and Shannon diversity indices were calculated; demographic maps were also made in which the presence and spatial distribution of the individuals of Miconia bracteolata and Tibouchina lepidota in the 10 plots that represented the population of the species in the area could be visualized. It was determined that, due to the number of juvenile species of each one, both have a high probability of survival in the study area and through the demographic maps it was known that Miconia bracteolata is a sceophyte species, tolerant to shade, while Tibouchina lepidota is a heliophyte specie, which requires a greater amount of light. It is concluded that the presence of individuals is higher in Tibouchina lepidota and this species is recommended for reforestation plans in the country.
