ABSTRACT This study evaluates land use and cover (LULC) changes their impacts on the fish community of a neotropical stream in Sorocaba River basin, Brazil, from 2006 to 2023. The watershed experienced landscape over time, categorized into four periods: rural interventions, urban restorative post‐restorative interventions. objective was understand LULC ecological consequences, focusing assemblages. There were significant differences time. Forested areas had most substantial impact community, explaining 32.7% variation, being only variable. reflected considerable human notably increase non‐vegetated 2.3% during interventions 46.9% reflecting environmental degradation caused by urbanization. severely affected after dam collapse 2013, leaving one surviving species, Phalloceros harpagos .

These findings highlight importance for at least partially recovering aquatic biodiversity ecosystems impacted activities.
