Gulls on film: roadkill scavenging by wildlife in urban areas
The impact of roads on wildlife (both directly through wildlife-vehicle collisions, and indirectly due to factors such as habitat fragmentation) has likely increased over time due to expansion of the road network and increased use and number of vehicles. In the UK, for example, there were only 4.2 million vehicles on the roads in 1951, compared to 37.3 million by the end of 2016.
