Lagoons are considered protected areas because these systems play a key ecological role. However, the extraction of macrophyte Schoenoplectus californicus is held for manufacture of handcrafts, being an alternative income for riverbank communities. This study evaluated the impact of S. californicus experimental cutting on benthic macroinvertebrates trough a field experiment. Macroinvertebrates were sampled at 1, 12, 26 and 60 days after the macrophyte cutting in demarked plots (1 m²), as well at control plots. The families number was not statistically different (ANOVA, p &gt; 0.05), but the total density of invertebrates, and the density of Ceratopogonidae were significant (ANOVA, p &lt; 0.05) for interaction between sampling date and treatment.
