Wild ungulate use of underpasses: tunnel length and availability of crossing opportunity matters
Jan Olof Helldin
Underpasses have a fundamental potential in mitigating infrastructure barriers for wildlife, considering that they are a relatively common feature across traffic networks. Increasing our understanding of the functionality of the different designs and localities of underpasses is therefore crucial within infrastructure planning and management. We analyzed crossing probability, based on movement-triggered automatic cameras, in moose (Alces alces) and roe deer (Capreolus capreolus), common wild ung
