The highest amphibian biodiversity across the globe is found in Madre de Dios, Peru, but this biodiversity may be threatened by mercury pollution from artisanal and small-scale gold mining (ASGM). Mercury is a neurotoxin and high levels have been reported in fish and raptors in this region. I created a vulnerability map for amphibians using remotely sensed imagery. This work will test map accuracy by quantifying mercury levels in soil.
