But highway construction creates larger problems of degraded habitat and “the barrier effect that reduces landscape connectivity,” Forman says. When roads and freeways chop a species’ territory up, they create a host of problems for the animals, who need freedom of movement to find food and mates, escape predators and make seasonal migrations.
