Roadkill refers to an animal or animals that have been struck and killed by motor vehicles on highways. It is important because of the wars timothy findley online pdf animal suffering, loss of wild animals, road safety, and the economic impact on both drivers and road management. First World nations, as they adopted the internal combustion engine and the automobile. In Europe and North America, deer are the animal most likely to cause vehicle damage.
The development of roads affects wildlife by altering and isolating habitat and populations, deterring the movement of wildlife, and resulting in extensive wildlife mortality. One writer states that “our insulated industrialized culture keeps us disconnected from life beyond our windshields. A study in Ontario, Canada in 1996 found many reptile killed on portions of the road where vehicle tires don’t usually pass over, which led to the inference that some drivers intentionally run over reptiles. To verify this hypothesis, research in 2007 found that 2. Indeed, several drivers were observed speeding up and positioning their vehicles to hit the reptiles”.
Male drivers hit the reptile decoys more often than female drivers. On a more compassionate note, 3. On roadways where rumble strips are installed to provide a tactile vibration alerting drivers when drifting from their lane, the rumble strips may accumulate road salt in regions where it is used. Roadkilled deer just south of Richmond, Indiana, US. Animals may show little external damage, especially if tossed completely off the roadway.
Very large numbers of mammals, birds, reptiles, amphibians and invertebrates are killed on the world’s roads every day. The number of animals killed in the United States has been estimated at a million per day. About 350,000 to 27 million birds are estimated to be killed on European roads each year. Mortality resulting from roadkill can be very significant for species with small populations. Florida panthers, and is the largest cause of badger deaths in England.
In 1993, 25 schools throughout New England, United States participated in a roadkill study involving 1,923 animal deaths. A recent study showed that insects, too, are prone to a very high risk of roadkill incidence. Research showed interesting patterns in insect roadkills in relation to the vehicle density. In 2003-2004, the Royal Society for the Protection of Birds investigated anecdotal reports of declining insect populations in the UK by asking drivers to affix a postcard-sized PVC rectangle, called a “splatometer”, to the front of their cars.
In 2011, Dutch biologist Arnold van Vliet coordinated a similar study of insect deaths on car license plates. He found two insects killed on the license-plate area for every 6. 6 trillion insect deaths by cars per year in the Netherlands, and about 32. 5 trillion deaths in the United States if the figures are extrapolated there. The study of roadkill has proven highly amenable to the application of citizen science observation methods. Project Splatter’ was started by Cardiff University in 2012, with the aim of estimating the impact of roads and motoring on British wildlife.
