US government sued over road project in Mojave tortoise habitat

Construction of a new four-lane highway through Red Cliffs National Conservation Area would violate environmental laws and put the tortoise and several other species at risk, a coalition of conservation groups says.

A coalition of conservation groups has sued the US government over the Trump administration’s decision to allow construction of a new four-lane highway through a national conservation area in southern Utah that includes protected habitat for the Mojave desert tortoise.

The group Conserve Southwest Utah argued the road through part of the “sensitive and scenic” Red Cliffs National Conservation Area would violate environmental laws and put the tortoise and several other species at risk.

Alternative routes

There are alternative routes that would solve vehicle congestion problems in the fast-growing area and the decision to cut through protected land sets a dangerous precedent, said the lawsuit filed against the US Interior Department and the Bureau of Land Management.

The coalition of state and national groups that sued hope that Democratic President Joe Biden’s administration will reverse the decision made in January allowing the road just before Trump left office.

Todd Tucci, senior attorney for the Advocates for the West group, called it “inconceivable” that new Interior Secretary Deb Haaland would support the highway.

The Interior Department did not immediately respond to an emailed request for comment on the lawsuit.

The Bureau of Land Management declined to comment.

Endangered species

Mojave desert tortoises, a threatened species, weigh up to 15 pounds (6.8 kilograms) and grow to about 6 inches (15 centimeters) high. They can live up to 80 years, according to the US Fish and Wildlife Service, and spend up to 95 percent of their lives underground. Their historic range includes parts of California, Nevada, Arizona and Utah.

Roads are problematic for the tortoises because they bring noise, garbage and lights, as well as the possibility of the tortoises being hit by cars as they slowly make their way across pavement, said Tom Butain, board president for Conserve Southwest Utah.

“Roads are one of the biggest problems tortoises have,” he said.

Highway supporters have said the four-lane highway is needed to keeping traffic flowing in the area around the city of St. George, which has a metro area of about 170,000 people and is one of the fastest-growing parts of the US.

Officials in Washington County, which encompasses St. George, praised the Trump administration decision to allow the road, saying it strikes a balance between protecting the tortoise and meeting the community’s transportation needs.

Conservationists have long worried that the project would be detrimental to wildlife and landscapes, some recently scorched by wildfires.
