Estudio demográfico de Gaultheria glomerata y Disterigma empetrifolium, en la vegetación análoga de indiviso, en la parroquia Baquerizo Moreno, cantón Pillaro, provincia de Tungurahua.

Abstract

The aim of this research was to carry out a demographic study of Gaultheria glomerata and Disterigma empetrifolium. The study was developed at Indiviso sector, which has an analogous vegetation between montane forest and shrubby moorland, located at 01°18'S; 78°30'W coordinates, altitude 30400 m.a.s.l., where an adaptation to the Braun-Blanquet methodology for vegetation cover was carried out by means of plots, which were established randomly, the minimum distance between plot and plot was considered 100 meters. In the field work, the existing vegetation cover was quantified by percentages within 10 plots of 10x10m, in each of which the subquadrants were evaluated in the form of an L, at each meter. The species were identified in the Herbarium of the ESPOCH, and the calculated data were 35.69% of vegetation cover for Disterigma empetrifolium and 13.19% for Gaultheria glomerata, which are in an abundance index of 2-3 on the Blanquet scale that tells us that it belongs to a moderately abundant and abundant cover. Taking into account the BraunBlanquet abundance index table, it was shown that according to its scale a species can be found by its abundance and dominance respectively, so it was determined that Disterigma empetrifolium, has a coverage that is between 25-50%, thus concluding that it is in an index 3 of Blanquet's scale, and Gaultheria glomerata was found in a percentage of 5-25% concluding that this species is in an index 2 of Blanquet's scale. It is advisable to carry out a long-term monitoring of the populations to obtain accurate data on the growth of the species and increase in vegetation cover and thus have more accurate data on vegetation cover at Indiviso sector.
