Trump's Wall and Wildlife
In the US-Mexico border region, a number of species need to cross the border to mate with their genetically different cousins, including the endangered North American jaguar. Black bears, would be threatened without being able to mate with Mexican bears. There is already a barrier fence between the US and Mexico. It is permeable, but distressed animals have already been observed, including the mountain lion and bobcat. Even birds, such as the low-flying pygmy owl and land-loving roadrunner, have been affected. Border infrastructure not only blocks the movement of wildlife, but... destroys the habitats, fragments the habitats and the connectivity that these animals use to move from one place to another.
