Mortality due to road trauma can have large negative impacts on some populations and often is biased towards age/sex classes that have higher rates of movement: individuals during the breeding season and juveniles while they are dispersing. A bias towards young males has been found in two previous studies of road kill Koalas in southeast Queensland. Such a bias was not found in the present study of Koala skulls from populations across Victoria. This may be due to the different Koala population structures and densities or road types and characteristics.
