# Pumas in Washington cut deer-vehicle collisions by 76% 2026-08-08T05:29:53+00:00 | World & Diplomacy | Indian Opinion Desk Corroboration: 1 independent outlet A study published in Current Biology has found that the presence of pumas on Washington’s Olympic Peninsula reduces deer-vehicle collisions by 76%. Researchers observed that deer in areas with pumas shift activity to daylight hours and are 15% less likely to be near roads, instead staying in remote habitats. This behavioural change leads to a 67% drop in the likelihood of a collision. The study highlights an ecosystem service from large carnivores that is often overlooked. In the US, deer-vehicle collisions cause 200, 400 human deaths and over $10 billion in damages annually, according to a 2025 study. ## Coverage - timesofindia.indiatimes.com Tags: deer-vehicle collisions, ecosystem services, pumas, road safety, Washington, wildlife Canonical: https://indianopinion.org/pumas-in-washington-cut-deer-vehicle-collisions-by-76/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
