Here we report the local extinction of Scinax caldarum, an endemic tree frog species of the Brazilian Atlantic Forest. We also report a reduction of the geographic range of this species to less than 15 % of the area in which it occurred 27 years earlier. We consider the excessive use of agrochemicals to be the main factor explaining the decline, including in farms with environmental certification. The local extinction of S. caldarum is a bioindicator of the severe impact of crops such as coffee and sugar cane, which heavily rely on agrochemicals. Stricter regulation of pesticides is needed to avoid damage to ecosystems and loss of biodiversity.
