Mexico's environmental authorities say they have declared the northern shore of the Caribbean island of Cozumel a protected nature area, with strict limits on human activity there.
The Environment Department says about 146 square miles (378 square kilometers) of the island and coastal waters will be protected under the measure.
The area designated Wednesday constitutes the shores and offshore shelf on the northern half of the island. The area is mostly unpopulated and well away from Cozumel's town, marinas and cruise ship dock.
Two species have native ranges only on the island: the Cozumel spiny lizard and the Cozumel racoon, which is a dwarf raccoon.
