Evaluación del estado de conservación de tres sitios de visita del atractivo turístico Laguna de Colta mediante macroinvertebrados acuáticos

Abstract

This research evaluated the conservation status of three Colta Lagoon tourist attraction visitor sites using aquatic macroinvertebrates. The methodology used consisted of characterizing the tourist attraction using the hierarchy card proposed by the Ministry of Tourism (MINTUR), in addition to monitoring the tourist condition, where parameters such as organic and inorganic waste, floating material of anthropogenic origin, and effects tht alter the landscape and flora were measured. For the monitoring of the environmental condition, information was collected on physical, chemical, and microbiological parameters, which one collected were compared with the quality standard of the Unified Text of Secondary Legislation for aesthetic and recreational use and use for the conservation of aquatic life. The Shannon-Weaver, Simpson, Margalef, Sorensen, and Jaccard indexes were used to analyze the biodiversity of the macroinvertebrate communities. Within the biological indexes, the BMWP/COL, ASPT and ABI indexes were applied; the results obtained showed that the water quality in polluted due to non-compliance with the parameters established within the standard, as well as the presence of low diversity of macroinvertebrates, with a doubtful water quality due to the biological indexes applied, also the relationship eith physical, chemical, and microbiological parameters and the presence of families of macroinvertebrates tolerant to pollution.
