Vegetação ripária como indicador da qualidade da água, na bacia Rio Puraquequara em Manaus, Amazonas, Brasil

Abstract

Riparian vegetation or riparian vegetation play an important role when preserved. The degradation of this type of vegetation causes damage to water quality, which is the incentive to supply the survival activities of the population and other species of animals that depend on the basin. The water quality analysis through the Rapid Assessment Protocol (RAP) is able to efficiently show how the disturbance level of the basin is found through riparian vegetation, as the form of monitoring is done with the naked eye and can be performed. by anyone who is properly trained in basin and vegetation characteristics. Thus, PAR was used to evaluate the water quality of the Puraquequara river basin, located in the eastern part of the city of Manaus, Amazonas, Brazil, and adapted to the Amazon region. It was applied by four evaluators at four points distributed throughout the basin every two months and at the end an average of the PAR score of the four evaluators was performed. The results show that the four PAR application points were classified into the 3 states (natural, altered and impacted) and that there were no significant differences between the four evaluators' eyes. Points 1 and 4 were classified natural and points 3 and 4 were classified as altered or impacted. Key Word: RAP, Water, Puraquequara
