Roads connecting wildlife.

Mexico has 407,958 km of National Highways in its road network. It is planned to build 2,000 km of new roads and improve existing ones by 90%. Environmental consultants, universities and NGOs are analyzing road impacts while citizen science increases day by day in the Country. There are bills for the implementation of wildlife crossings and laws are being draft to maintain the connectivity of biological corridors in front of the highways.

Key facts

The first published study of road ecology in Mexico took place in 1997 in Tuxtlas, Veracruz (Morales-Mavil et al. 1997).

The first jaguar crossing at an underpass in Latin America was detected along the Nuevo Xcan-Playa del Carmen highway. Jaguars were recorded using the underpasses 24 times, consisting of 4 males and 2 females.

Mitigation measures are being planned for Federal Highway 2 in the Sky Island ecosystem (Sonora, Chihuahua, Arizona, New Mexico) that will connect jaguar, black bear, pronghorn and desert bighorn sheep.
