How does construction of roads affect the environment?
Besides the direct habitat loss due to the road itself, and the roadkill of animal species, roads alter water-flow patterns, increase noise, water, and air pollution, create disturbance that alters the species composition of nearby vegetation thereby reducing habitat for local native animals, and act as barriers to …
What are the impacts of road construction?
Inadequately constructed forest roads can cause severe environmental impacts including road surface erosion and sediment yield [1, 2], pollution of off-site waters [3–5], slope failures and mass movement [6, 7] direct loss of habitat (by the conversion of the original land cover into an artificial surface) [8] and …

How do roads impact wildlife?
In addition to fragmenting habitat, constructing a road alters the habitat. When a road runs through a forest, it creates an edge habitat along the portion of the forest that fringes the road. This can have consequences for birds, as predation rates on bird nests are sometimes higher in edge habitats.
