Two sites, two different faunal objectives and two different issues. The first site located along Heart Lake Road in the City of Brampton had a wildlife tunnel installed (2 m closed foot box culvert) based on community road mortality data and concerns around the impacts to the turtle population. Is the new tunnel moving wildlife? And if so, what? The first attempt to document wildlife using the tunnel employed typical PIR camera technology and yielded only typical urban tolerant species. What would a different technology, the Hobbs Active Light Trigger (HALT-2) tell us? Will the installation of two new ACO tunnels in different habitat locations yield different results, and how can this knowledge be applied to other locations in the jurisdiction? The objective at the second site was to safeguard the annual migration of the endangered Jefferson salamander (Ambystoma jeffersonianum) population across a major regional road in the City of Richmond Hill where traffic volumes are 5000 vehicles per day. Here there are plans to widen and redesign the road, and there needs to be a detailed understanding of where and how the salamanders move before making significant investments in long term mitigation efforts such as the installation of new ACO wildlife tunnels. What are the most important habitats to connect? We are letting the animals tell us. Through the use of road ecology surveys, Holohil BD-2 transmitters, and Northwest Marine Technology VIE tags we are tracking the movement corridors that the animals are using, along with the related landscape conditions, to make more informed decisions.
