| July 2023: New research from my PhD student Felicity Charles has been published in Wildlife Letters. This came from Felicity's honours thesis, in which she found that animals crossed roads via drainage culverts only about 6% of the time, preferring the road surface. |  |
Existing crossing structures aren't, therefore, super popular with wildlife. More would need to be done before they could be effective at mitigating roadkill.
