Bison have returned to Mexico for the first time since the 1800s, with Mexican officials releasing 23 donated U. S. animals in northern Chihuahua State.

While talking to reporters, Environment Secretary Juan Elvira Quesada said, “Parts of northern Mexico once represent the southern range for huge herds of the roaming bison before they were killed off.”

Further, the environment secretary told media persons that the movement and grazing of the bison can help regenerate natural grasses and grassland in Chihuahua’s El Uno nature reserve.

According to him, the basic aim is to have at least 100 bison in Mexico in coming three years. He also urged the United States to stop building border fences that can be harmful for the natural animal’s migration routes of animals.

The donated bison came from the Wind Cave National Park in South Dakota.
