Service Proposes Critical Habitat for Miami Tiger Beetle

Press Release
Service Proposes Critical Habitat for Miami Tiger Beetle

The U.S. Fish and Wildlife Service is proposing to designate critical habitat in Miami-Dade County, Florida for the Miami tiger beetle, a species listed as endangered under the Endangered Species Act (ESA) in October 2016. The Service is also announcing the availability of a draft economic analysis of the proposed critical habitat designation.

“Only two small populations of the rare Miami tiger beetle still survive in its pine rockland habitat,” said Leopoldo Miranda-Castro, Service Regional Director. “Listing the species as endangered in 2016 was the first step to ensure its continued survival and conserve its shrinking habitat. Proposing critical habitat is another crucial step.”

The Miami tiger beetle is one of the smallest tiger beetles in the U.S. and is only found in Miami-Dade County, Florida. It thrives in the imperiled pine rocklands ecosystem that is unique to southern Florida and the Bahamas. As development, encroaching vegetation and impacts of climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

have persisted, this ecosystem has faced major losses. An estimated 98% of the historical pine rockland habitat within Miami-Dade County outside of Everglades National Park has been destroyed and this habitat loss is expected to continue. The small population size of this species and its restricted range adds to the severity of these threats.

When a species is listed under the ESA, the Service is required, where possible, to identify areas essential to the conservation of that species, known as critical habitat. The areas selected for designation are selected using the best available scientific data. In total, approximately 1,977 acres in Miami-Dade County, Florida, fall within the boundaries of the proposed critical habitat designation.

The units being proposed for critical habitat include areas that were occupied by the Miami tiger beetle at the time of listing in 2016. Additionally, some units outside the current occupied areas are being proposed for designation. The unoccupied units being proposed are within the historical range of this species, contain suitable pine rockland habitat and essential physical and biological features, and have been determined to be essential for the conservation of this species.

The two units that were occupied at the time of listing in 2016 account for approximately 1,572 acres or 80% of the proposed critical habitat. The remaining 14 units total 405 acres, with only 16 acres of that not currently designated as critical habitat for other federally listed species. Overall, 57% of Miami tiger beetle proposed critical habitat is found on county lands, 25% on federal lands, 12% on state lands, and 7% on private lands.

Critical habitat designation requires federal agencies to ensure that actions they plan to undertake, fund or authorize do not destroy or adversely modify that habitat. It does not establish a wildlife refuge, allow the government or public to access private lands or require non-federal landowners to restore habitat or recover species.

As required by the ESA, the Service assessed the economic impacts of this proposed critical habitat designation. The draft economic assessment found minimal costs associated with this proposed designation, limited to additional administrative costs for considering adverse modification of the beetle’s habitat during Section 7 Section 7
Section 7 Consultation The Endangered Species Act (ESA) directs all Federal agencies to work to conserve endangered and threatened species and to use their authorities to further the purposes of the Act. Section 7 of the Act, called "Interagency Cooperation," is the mechanism by which Federal agencies ensure the actions they take, including those they fund or authorize, do not jeopardize the existence of any listed species.
