Passive acoustic monitoring has been essential to understand vaquita population trends since 2011. Now we know that population was composed out of less than 20 individuals in 2018. In this report we present results of acoustic monitoring during 2021. Sampling effort occurred between June and November under two schemes. One was inside Vaquita Protection Refuge from June to September, and other just inside Zero Tolerance Area (ZTA), during October and November.
