Linking a Cougar Decline, Trophic Cascade, and Catastrophic Regime Shift in Zion National Park

03/26/15 Guest Commentary by William Ripple and Robert Beschta

Ripple and Beschta's work in Zion National Park was one of the first major studies to help demonstrate the importance of top predators in maintaining healthy, diverse landscapes. When the park gained popularity and more people visited, cougars were scared off. Without natural predators, mule deer over-browsed cottonwoods, causing a shift in vegetation, more erosion along stream banks, and ultimately fewer reptiles, amphibians, fish, and insects. These results, replicated in Yellowstone, have broad implications with regard to our understanding of ecosystems where large carnivores have been removed or are being recovered.

Killing Mountain Lions to Grow Mule Deer

10/01/15 Guest Commentary by Marc Bekoff

Animal expert and biology professor Marc Bekoff discusses Colorado's misguided plan to kill mountain lions in the hope it will increase deer populations. Though it may seem like less predators would yield more prey, there is no science to back the state's plan. In fact, killing large numbers of mountain lions causes chaos and increases ecological problems. Please contact the Colorado Parks and Wildlife Commission and urge them to vote against this plan which would cause significant and widespread collateral damage.

Environmental Scorecard

League of Conservation Voters

The League of Conservation Voters' scorecard considers the Utah State Legislature's environmental records since 1971. It quantifies the environmental votes of each individual legislator — an important first step in considering accountability — and provides critical qualitative assessments as well. The scorecard will help you to know your legislator before you write a letter in support of cougars.

Becoming a Mountain Lion Activist

There are lots of opportunities to take action!

Are you new to mountain lion activism? You want to change your local environment to improve it for cougars... but you don't know how to start. You may feel like you are all alone... but it takes just one person to change the attitudes and lifestyles of hundreds of others. You don't need to belong to a group. It doesn't take special skills or superhuman abilities. You just need to care enough about cougars to want to help them survive. You've already done the hard part, now let us help you with the next step.
