Road traffic threatens wildlife in urban green spaces, where vehicle collisions cause mortality and noise causes disturbance and reduces habitat quality. With generous support from the National Capital Commission and the Friends of Gatineau Park, we are exploring the effects of traffic mitigation and reduced noise disturbance on wildlife in Gatineau Park. We are engaging citizen scientists, using camera traps and acoustic recording technology, and surveying roadkill on roads open or closed to vehicles. In this way we hope to get a picture of how wildlife are responding to traffic mitigation, while engaging local volunteers. We hope to assess the effectiveness of traffic mitigation as a practical solution for biodiversity at urban-wildlife interfaces.
