This Animal is the Cause of Most Wildlife-Related Injuries in Yosemite and It’s Not What You Think

Yosemite National Park has issued an important wildlife advisory that might surprise visitors: deer—not bears—are responsible for the most wildlife-related injuries in the park.
While mule deer may appear calm and harmless as they graze in meadows or wander near trails, they’re still wild animals. Yosemite officials warn that startled deer can lash out with sharp hooves or antlers, often when people try to get too close or offer food.
“While these animals may seem harmless to humans, they are still wild and skittish,” the park wrote. “A deer will lash out and defend itself if startled.”
Feeding or approaching wildlife is illegal in Yosemite, and rangers are urging visitors to respect that law—for their own safety and the animals’ well-being. Getting too close can lead to dangerous encounters and also makes wildlife too accustomed to humans.
The park’s advice? Keep your distance and admire these iconic animals from afar.
This warning is part of a broader effort across U.S. national parks to protect both visitors and wildlife. At Death Valley National Park, officials recently issued a reminder to avoid bringing mylar balloons, which are commonly found littering the landscape and pose a threat to local animals.
Whether it’s deer, bears, or even balloons, the lesson is simple: respect the wild.
