The U.S. Fish and Wildlife Service is the nation's wildlife management and conservation agency. The Florida Ecological Services Office is the primary Service office serving the state of Florida on matters of federal threatened and endangered species conservation, including supporting the conservation of private lands; and working with federal agencies and other partners to address fish, plant, and wildlife impacts resulting from their actions. The Florida Ecological Services Office is headquartered in Gainesville, with offices in Panama city, Jacksonville, and Vero Beach to better serve those areas of the state.

What We Do

Across Florida, we carry out the Service’s mission by:

  • Conserving imperiled species.
  • Helping federal agencies identify and address negative plant, fish, and wildlife impacts from projects they fund or authorize.
  • Conversing with the American public about wildlife conservation via social media, educational programs, public hearings, and other forms of public interaction.
