Celebrate the species you love during CO Endangered Species Week

Banner featuring Colorado endangered, threatened, and imperiled species

On May 11-17, 2025, Rocky Mountain Wild and our partners will host the 9th annual Colorado Endangered Species Week! This week is dedicated to providing educational events and advocacy opportunities to protect the planet and species at risk here in Colorado.

During this week, Rocky Mountain Wild and our partners organize speakers, fundraisers, direct actions, and other activities along the Front Range, with major events occurring in Boulder and Denver, as well as activities you can take part in from the comfort of your own home.

Join us for the events and for The Most Awesome Environmental Online Auction in the Front Range! All items in this auction have been donated by members of a green coalition (1% for the Planet, Certifiably Green Denver, Certified Green Lafayette, Climate Neutral Certified, The Conservation Alliance, Good Food 100, Green America, etc) or the item itself may replace a less environmental one.

Events for your favorite Colorado endangered species:

During Colorado Endangered Species Week, we’ll be focusing on a few of our important species or wild places, or a solution that protects our important species or wildly places here in Colorado. We will feature a suite of activities, including things to read, direct actions to take, and things to watch to help us learn about and advocate for our Colorado imperiled, threatened, and endangered species!

Events coming soon.

The Most Awesome Environmental Online Auction in the Front Range:

Colorado Endangered Species Week includes The Most Awesome Environmental Online Auction in the Front Range, with auction items that are either donated by a business with a green coalition membership or items that are environmental in nature.
