Editing Roadkill (section)

==Causes==

The development of roads affects wildlife by altering and isolating habitat and populations, deterring the movement of wildlife, and resulting in extensive wildlife mortality.<ref>{{cite journal |last1=Ashley |first1=E.

===Intentional collisions===
A study in [[Ontario]], Canada in 1996 found many reptiles killed on portions of the road where vehicle tires do not usually pass over, which led to the inference that some drivers intentionally run over reptiles.<ref name="Ashley 2007"/>{{rp|138}} To verify this hypothesis, research in 2007 found that 2.7% of drivers intentionally hit reptile decoys masquerading as snakes and turtles.<ref name="Ashley 2007"/> Several drivers were seen to speed up when aiming for the decoys.<ref name="Ashley 2007"/>{{rp|142}} Male drivers hit the reptile decoys more often than female drivers.<ref name="Ashley 2007"/>{{rp|140–141}} However, 3.4% of male drivers and 3% of female drivers stopped to rescue the reptile decoys.<ref name="Ashley 2007"/>{{rp|140}}

===Road salt accumulations===
{{main|Rumble strip#Wildlife attraction}}
On roadways where [[rumble strip]]s are installed to provide a tactile vibration alerting drivers when drifting from their lane, the rumble strips may accumulate road salt in regions where it is used. The excess salt can accumulate and attract both small and large wildlife in search of [[salt lick]]s; these animals are at great risk of becoming roadkill or causing accidents.<ref>{{cite report |first1=M.
