Vehicle collision resulting in animal mortality is a common daily occurrence, although few studies have considered the impact on herpetofauna in urban areas. Over a 7 year period (2003 - 2010), 1.4 km of suburban streets of Falconbridge that interface with the Greater Blue Mountains World Heritage Area, west of Sydney, was surveyed on foot two to four days a week, typically soon after dawn. Over the period a total of 86 reptiles that represented 20 species: 38% of the lizard and 56% of snake species known from the area were collected as road kills due to collision with vehicles. This equated to approximately one individual per month that was collected across the 7 years. Representatives of six frog species were also identified as road kills (33% of the local frog fauna). In Faulconbridge, 20-30 km of 50 km/hr roadways interface with the national park and there are 26 towns within the World Heritage Area. Each of these towns has a network of streets that covers much more than just the perimeter of the town... |
