Diversidad florística del ecosistema páramo en la zona piloto Atillo ubicada en la subcuenca del río Chambo, cantón Guamote, provincia de Chimborazo.

Abstract

The research project aimed to determine the floristic diversity of the moorland ecosystem in the Atillo Pilot Zone in the Chambo River Sub-basin, town of Guamote, Province of Chimborazo, through the application of the GLORIA methodology. This methodology was applied in three peaks, each one of them, a count and sampling of the species found were carried out, they took place in 16 subplots of one square meter each, distributed in the four cardinal points, with help of a lattice mesh (1 m2, 10x10 lattice). In the study area, a total of 22 vascular species, belonging to 12 families, where the largest amount of species corresponding to the Asteraceae family (9) and the largest number of individuals found belonging to the species Calamagrostis intermedia (872) and the least amount of individuals belonged to the species Gentiana sedifolia (1) and Margyricarpus pinnatus (1). The species Calamagrostis intermedia had a higher percentage of coverage for tops one and two, with 65.94% and 54.06% respectively, while Aetheolaena lingulata showed a higher coverage in the top three with 40.19%. The values of the Shannon index (1.56, 1.97, 1.72, respective to peaks 1, 2 and 3), indicated that the three peaks under study offer a diversity mean, while for the Simpson index (0.79, 0.72, 0.60, respectively), the results expressed that the tops had a high diversity. According to the Sorensen index (0.79,0.72, 0.60), there was a floristic similarity between tops 1 and 2; and between peaks 1 and 3, but the tops 2 and 3 were only moderately different floristically.
