The Endangered Species Coalition is a group that appears in the Sonic Boom television series. It is an animal welfare alliance dedicated to preserving Seaside Island's endangered animal species within the perimeters of government regulations.
At some point, the Endangered Species Coalition made Fastidious Beaver their chairman so they could hold meetings in Hedgehog Village's library. Amy would also become the vice-chairman of this group.
When a widabit chose Sonic's Shack for its courting ritual, the Endangered Species Coalition followed regulations and vacated Sonic, although Amy tried helping Sonic advance the ritual. Meanwhile, Fastidious Beaver would use decrees by ESC to protect a widabit that invaded a fight between Eggman and Sonic. As fifty widabits were later gathered at Sonic's Shack, Fastidous and Amy permitted Sonic to relocate them to a nature preserve (after two widabits had finished their courting ritual).
