Aquatic macroinvertebrates are often used as bioindicators of water and ecosystem quality due to their sensitivity to pollution. For these reasons, the Santa Barbara Audubon Society developed a Citizen Science program in collaboration with UCSB to collect long-term data on aquatic macroinvertebrate assemblages and water quality in order to understand the changing health of the slough. THis poster was presented at the UCSB 2023 EEMB Research Symposium.
