Estudio de los servicios escosistémicos ligados al agua y diversidad florística en el Páramo del Igualata, regional Hualcanga, cantón Quero, provincia de Tungurahua.

Abstract

The present research proposes: to study the ecosystem services linked to water and floristic diversity in the Hualcanga regional Igualata páramo; five plots of sampling of 25m2 were installed with 4 subplots of 1m2, 30 samples of terrestrial vascular plants were obtained, identifying 17 botanical families, 26 genera and 27 species, plus 1 lichen and 1 moss of family, genus and species were collected. identified. It was determined that the species that stands out with the highest value index was Lachemilia orgiculata with 44.06%, this is because the species was found in 4 of the 5 study plots, in second place we have Calamagrostis intermediate species with 8.21% while the species Vicea was the one with the lowest important value index presented with 0.50%, this is because it was the species with the lowest number of individuals. The Rosaceae family presented the highest index conn39.61% Poaceae and Asteraceae families have dominance in this ecosystem with values of 9.63% 5.79% respectively. According to the Shannon index, plots 2 and 4 are those with high diversity e corroborates with what was obtained in the Simpson index; in the Sorensen index it shows us that plots P4 vs P5 are very similar plots P1 and P3 are fairly similar and the remaining plots are dissimilar which indicates that vegetation can be found in certain areas of the investigation. The flow that possesses the Regional is of 8,12 L / s, supplying to the families and his ecological flow is of 0,83 L / s having a discharge that satisfies the needs of the settlers.
