  1. Install barrier fencing and underpasses along roads

    A study in 1994–1995 in Florida, USA (Foster & Humphrey 1995) found that four underpasses beneath a highway, in areas with roadside fencing, were used by Florida panthers Felis concolor coryi and a range of other mammal species. Ten crossings were recorded through underpasses by panthers, as were 361 by white-tailed deer Odocoileus virginianus, 133 by bobcats Lynx rufus, 167 by raccoons Procyon lotor and two by black bears Ursus americanus. Panther records were thought to relate to two individuals. Four concrete bridge underpasses (21–26 m wide, 49 m long) were monitored along a 64-km stretch of a four-lane, divided highway. Barrier fencing, 3 m high, ran along the highway. Infrared game counters and cameras were used to monitor underpasses for 2, 10, 14 and 16 months in 1994–1995.
