Biologists around the world track tremendous increase in wildlife death on highways

The New York Times – In Brazil, Animals Cross a Road of No Return – “Highway BR-262 is among the deadliest in the world for wildlife. Biologist Wagner Fischer has been monitoring its grim toll for more than two decades…In 2014, a team led by Julio Cesar de Souza, of the Federal University of Mato Grosso do Sul, took another look at roadkill on the BR-262. Over 15 months, they found 518 carcasses from 40 species, and noticed a roadkill site every four miles — a tenfold increase since 2002, when Dr. Fischer presented some of his findings at a transportation conference. That study, as well as a study in 2017 that counted more than 1,000 large mammals killed in one year on the BR-262, prompted Mr. Fischer to finally publish his data. By contrast, on California’s Interstate 280 in the Bay Area, the state’s deadliest road for animals, 386 creatures died in collisions between 2015 and 2016. In Britain, more than 1,200 animals died in road collisions across all major highways in 2017, according to a recent report…”
