A road in London was shut down for nearly a month in order to help the wildlife in the area.

It comes as the U.S. Fish and Wildlife Service has issued emergency protection for a toad threatened by extinction.

Dixie Valley toads live in a remote area near Reno, Nevada, in a 760-acre wetland complex, but the Fish and Wildlife Service says Dixie Valley toads are in danger.

The agency says protecting small population species like these small toads is crucial.

Nevada is one of the driest states in the country, and the agency says the toads help maintain the area's ability to adapt to the climate.

A geothermal project is planned for this area, and the agency is concerned it could destroy the entire population of Dixie Valley toads.

It issued an emergency protection for the toads, which will last for 240 days, or about 8 months.

In the UK, Froglife helps with conservation and education projects.

One of its major projects is Toads on Roads.

Toads are particular about where they breed, and often migrate back to the same ponds each year, so the project registers sites as migratory crossings, and helps coordinate local toad patrols.

Patrols can apply for road warning signs and help the toads cross the street safely.

One road in London was completely shut down for more than three weeks to allow toads to cross safely.

Toads typically emerge from hibernation any time from January through April.

The Toads on Roads project has been running for more than 20 years.
