Roadkill in Tasmania

As we've discussed in class, one of the most vicious predators plaguing Tasmania is none other than the car. However, what exactly are the details surrounding roadkill on this island state?
Varying in size, shape, and origin, the car is an aggressive, metal beast that travels at high speeds along designated, asphalt roads and highways killing anything in it's path. With species ranging from Honda and Toyota to BMW and Audi, cars are diverse in appearance, but just as deadly regardless of their looks. In Tasmania, the estimated number of roadkill per year is just over 290,000 meaning that per day, 794 animals are killed and per hour, 32--all at the hands (or wheels, I guess) of cars. When breaking down the numbers, cars tend to have a special affinity for several species, inclusive of brush tailed possums, pademelons, wallabies, and Tasmanian devils with numbers killed per year at 108,543, 28,854, 15,829, and 3,392 respectively.
The cars prime feeding hours are at dawn and dusk when visibility is relatively low. I hypothesize that during these hours, the cars utilize this dimmed lighting to their advantage, using their unique ability to project headlights onto their prey to stun the animal, and go in for the kill.
Because of this astounding number of kills per year solely by the car, the Tasmanian government is attempting to hinder the cars hunting ability, advising that maximum speeds during their prime hunting hours is only 60 (rather than 80) km/hr. In slowing down these cars, their hopes is that these animals will have time to flea the road before the cars attack.
I am shocked to find that BOSP is allowing us to travel to such a dangerous place, ravaged by these rogue cars. However, because of the low number of attacks on humans, I have high hopes for a safe seminar.

  1. I would be terribly frightened if Tasmania had as many people die as they do animals in their roadkill

  2. I wonder if the general population of Tasmania is aware of the damage they are inflicting...

  3. Animal roadkill is also dangerous for humans because it could cause collisions with sudden halts and vehicles veering off into dangerous directions. I hope the Tasmanian government is looking into improving the safety for animals and humans alike.
