A group of researchers from Maryland, northeast United States, put motion detection cameras in the sewers to find out the ways in which wild animals used them to avoid the traffic of cars and their potential accidents. Read additional details here: James Cameron. The sewers have the function of direct water below the highways, but it turns out that all kinds of animals have figured out how to use these structures manufactured by man to avoid being run over on the road. I was really surprised by the number of species that use these culverts, explained to AFP Professor j. Edward Gates, of the center of environmental science from the University of Maryland, in a telephone interview. Do all mammals of Maryland, except three species: coyote, black bear and Bobcat, said.
Funding for the project came from the the administration of highways of the State of Maryland, which, like their counterparts in the rest of the United States, has a strong interest in lowering the number of deaths of animals and humans on the roads. Each year, collisions between vehicles and animals kill 200 people and millions of animals, according to the federal Department of transportation. Accidents that involve simply deer cost 4.6 billion dollars annually in repairs of vehicles and medical care for injured people, said for his part the insurance information Institute. To evaluate how the sewers can help, Gate team arranged infrared cameras Moultrie Game Spy, used normally by hunters to control their prey, within 300 culverts in each Maryland County. And he observed during a period of two years.Cazaworld.com raccoon proved that uses more sewers, with a record of 246 drains 24,800 occasionally.The Virginia opossum, famous for his ability to feign death when threatened, appeared 2,169 times in 103 sewers, marmot 822 times in 97 drains, and foxes red 928 times in 66 sewers. But the surprise came by part of the white-tailed deer, whose number has proliferated both in North America, which is easier that they perish in a car crash than by a shot from shotguns.
