SALT LAKE CITY— Author Terry Tempest Williams, local organizations and community members will hold a rally and press conference Wednesday to announce a federal lawsuit to protect Wilson’s phalarope, a migratory bird species whose fate is inextricably linked to the embattled Great Salt Lake.

The groups’ notice of intent to sue the U.S. Fish and Wildlife Service says the agency has failed to meet the legal deadline to determine whether the birds should be protected under the Endangered Species Act.

Wilson’s phalaropes are threatened by the collapse of saline lake ecosystems essential to their survival. Great Salt Lake is the most important of these. More than 60% of the entire population lands on the shores of Utah’s largest lake during their migratory journey and a healthy Great Salt Lake is critical to the species’ survival.

What: Press conference calling for action to protect Wilson’s phalarope and announcing the launch of a lawsuit against the U.S. Fish and Wildlife Service.

When: 11 a.m., Wednesday, Oct. 1, 2025

Where: Great Salt Lake, beach on the north side of Saltair.

Who: Concerned community members, along with the Center for Biological Diversity, Utah Physicians for a Healthy Environment, Utah Youth Environmental Solutions, Utah Sierra Club, Save Our Great Salt Lake, Great Salt Lake Interfaith Action Coalition and Making Waves. The event will also feature the Great Salt Lake vigil phalarope puppets and waves.
