Universidad Complutense de Madrid (UCM) in Spain conducted a research project on the negative effects of roads on animal populations with a focus on large mammals in developed countries.
The study included mammal species such as bears and foxes (36 %), along with hoofed animals like deer and antelope (15%), marsupials such as koalas and kangaroos (14%) and tortoises (13%). The study revealed that habitat loss due to extensive land clearing and occupation for roads affects animals greatly.
The causes highlighted in terms of the negative effects of roads on animal abundance included species that are vulnerable to traffic disturbances; noise and lights pollution, traffic motion and those susceptible to road mortality. Land clearing and tree felling for roads causes almost similar kinds of destruction as deforestation.
Species like bats, and invertebrates are also affected by transportation networks. The study lacked consideration of such species. Also the consideration of developing nations would have given more perspective on different species.
