Washington pumas linked to 76% drop in vehicle collisions
A study published in 'Current Biology' reveals that the presence of pumas in Washington's Olympic Peninsula has reduced deer-vehicle collisions by 76%. The predators influence deer behavior, causing them to avoid roads and shift their activity to daylight hours.
Why it matters
This research highlights how apex predators provide essential ecosystem services, including human safety, by naturally regulating prey movement.
Whoever thought animals would be able to prevent accidents? According to a recent study published in 'Current Biology' the presence of pumas in Washington has decreased the risk of road collisions immensely. Researchers found that the presence of pumas in the Olympic Peninsula area of Washington has changed the behaviour of the local deer population, thus decreasing the animal-vehicle collisions and improving overall safety.In areas where pumas are present, there is a 76% reduction in the number of deer-vehicle collisions because deer shift activity toward daylight hours.
