Tourist Attractions

By Kristy Tolley

Yellowstone National Park is one of the most visited parks in the United States and is home to a diverse range of wildlife, including wolves, grizzly bears, elk and cougars. Cougars, also known as mountain lions or pumas, are one of the top predators in the park. Many visitors and researchers are interested in understanding the number of cougars present in the park, as well as the factors that affect their population size.

Background on Yellowstone National Park

Yellowstone National Park is located in the western United States and covers an area of 2.2 million acres. It was established in 1872 as the first national park in the world and is home to some of the most iconic geothermal features, including the Old Faithful geyser. The park is also home to a diverse range of wildlife and ecosystems, including forests, grasslands and wetlands.

The Cougar Population in North America

Cougars are found throughout North America, from Alaska to the southern tip of Argentina. They are solitary animals and are known for their agility and stealth. Cougars are apex predators, meaning they are at the top of the food chain, and their populations are an important indicator of the health of ecosystems.

Previous Studies on Yellowstone Cougars

Several studies have been conducted on the cougar population in Yellowstone National Park. In the past, researchers used methods such as radio collars and camera traps to track and monitor the animals. These studies revealed important information about the behavior and ecology of cougars in the park, including their hunting patterns and habitat preferences.

New Methods for Tracking Cougars

Recently, researchers have begun using new methods to track cougars in Yellowstone. These methods include genetic analysis of hair and scat samples, as well as GPS collars that allow for more precise tracking of individual animals. These new methods have provided valuable insights into the population size and distribution of cougars in the park.

Results of Recent Cougar Studies in Yellowstone

Recent studies have suggested that the cougar population in Yellowstone is relatively stable, with an estimated 80 to 100 individuals living in the park. However, the population size can vary from year to year, depending on factors such as prey availability and competition with other predators.

Current Population Estimates of Cougars in Yellowstone

The most recent estimate of the cougar population in Yellowstone is around 80 to 100 individuals. While this is a relatively small population size, it is important to note that cougars are highly adaptable animals and can survive in a range of habitats and conditions.

Factors That Affect Cougar Population Size

Several factors can affect the size of the cougar population in Yellowstone, including prey availability, competition with other predators, disease, and human activities such as hunting and development. Understanding these factors is crucial for effective management of the cougar population in the park.

Human and Cougar Interactions in Yellowstone

Human and cougar interactions are relatively rare in Yellowstone, but when they do occur, they can be dangerous for both humans and animals. The park has implemented measures to reduce the risk of these interactions, such as closing trails and campsites when cougar activity is high.

The Future of Cougar Management in Yellowstone

Effective management of the cougar population in Yellowstone is crucial for the health of the park’s ecosystems and the safety of visitors. As new methods for tracking and monitoring cougars become available, it is likely that our understanding of these animals will continue to evolve, leading to more effective management strategies.


The cougar population in Yellowstone National Park is an important indicator of the health of the park’s ecosystems, and researchers have used a range of methods to study these elusive animals. Recent studies suggest that the population size is relatively stable, but a range of factors can affect their numbers. Effective management of the cougar population in Yellowstone is crucial for the safety of visitors and the health of the park’s ecosystems.
