Yellowstone’s Elk Population

Yellowstone National Park is home to a significant elk population, ranging from 10,000 to 20,000 during the summer. These majestic creatures live in six to seven different herds throughout the park. This rich biodiversity makes Yellowstone a haven for wildlife enthusiasts.

The Mating Season: A Time to Be Cautious

As the mating season, also known as the rut, approaches in September and October, Yellowstone National Park has issued a crucial warning for visitors. During this period, bull elk become particularly aggressive and territorial, making it imperative for visitors to maintain a safe distance. The National Park Service (NPS) advises staying at least 75 feet away from any elk, equalling the length of two full-sized buses.

Safety Guidelines for Visitors

To ensure visitor safety, the NPS recommends several measures. Always look around corners before exiting buildings or walking near blind spots to avoid surprising an unsuspecting animal. If you encounter an elk, back away immediately. In the event of a charge, seek shelter in your vehicle or behind a tall, sturdy barrier. If no shelter is available, running is advisable. Capturing wildlife photos is popular in Yellowstone, but it’s crucial never to approach or follow animals for pictures. Instead, use a lens with a focal length of 300 mm or more to maintain a safe distance.

Understanding Elk Behavior and Physiology

Male elk, or bulls, can weigh around 700 pounds and stand 5-feet-tall at the shoulder, while female elk, or cows, weigh about 500 pounds and are shorter. Bulls grow antlers in the spring that drop off by March or April the following year. Elk primarily feed on grass, sedges, herbs, shrubs, and even the bark of aspen trees and aquatic plants.
