Habitat Fragmentation & Alteration. In addition to causing direct mortality, roads can have a number of indirect impacts such as habitat fragmentation. This can result from either animals not being able to cross the road without being killed or through avoidance of the road.

What are the direct and indirect effects of roads?

The biotic consequences of the following effects of roads are considered below: direct effects include roads as barriers, enhancement of dispersal, roadkill, and effects on habitats; indirect effects include results of the access that roads provide to previously inaccessible areas, changes in water and air quality,…
