Data were collected from sixteen river sites within and around the Iracambi
NGO (non governmental organisation) land in Rosario da Limeira, Minas Gerais,
Brazil, during the wet season from September 28th to December 18th, 2022. The
sites included eight rivers in unprotected areas and eight in protected
riparian zones. The dataset includes measurements of abiotic parameters: air
and water temperature, salinity, flow rate, pH, dissolved oxygen, nitrate, and
rainfall. Freshwater invertebrate biodiversity was surveyed using modified
kick sampling, and Biotic Index scores were calculated for identified
invertebrate groups.
