Known for the eponymous reptiles that inhabit the nearby swamps, the migrant detention center dubbed “Alligator Alcatraz” faces the possibility of being shut down over concerns about some of the area’s lesser-known inhabitants – the Everglades’ bats, panthers, and storks.

A federal judge on Wednesday is set to hold an evidentiary hearing over whether to block operations at the controversial facility because construction of the site allegedly bypassed federally required environmental impact studies.

The hearing – at which federal, state, and tribal officials are expected to testify – comes amid heightened scrutiny of the facility, which was once touted as a “one-stop shop to carry out President Trump’s mass deportation agenda.”
