I'm currently working on a highway project in Quebec (Canada) and we are at the stage of designing wildlife passageways for small and large wildlife.

We are looking for, idealy, a study on comparative tests between different types of wildlife passages. If not available, report on monitoring programms and summary reports on what passage work best or not.

We are interested in case study from all around the world (Europe, America, Australia, etc), if you know someone or have good reference, please contact me at [email protected].

Thanks you so much for your help!
