Even though trees can be replanted, the variety is limited. Monocrops = limited variety of plants and animals. Cut off access to portions of habitats. Increased incidence of animals being hit by cars. One way of getting rid of habitat fragmentation. Can expose animals to greater threat of being killed. 44 wildlife crossing structures (overpasses and underpasses) Has the most wildlife crossing structed and most enclosed fencing. The introduction of non-native species to new environments.
