Colorado Butterfly Monitoring Network

Colorado Butterfly Monitoring Network (CBMN) is a community science project led by Butterfly Pavilion that harnesses the power of volunteers to conserve Colorado butterflies.

Established in 2013, the Colorado Butterfly Monitoring Network (CBMN) is a long-term community science project led by Butterfly Pavilion that harnesses the power of volunteers to conserve Colorado butterflies.

Butterflies are not only beautiful, but they also play a vital role in the ecosystem, serving as both pollinators and as food for other animals. Knowing which butterflies are active in our state gives us important information about the health of our local ecosystems.

CBMN volunteers observe and record butterflies in open spaces and parks multiple times per season, gathering essential data that land managers can use when making conservation decisions. It’s a fantastic chance to get outdoors and learn about butterflies, while having a positive impact on conservation in Colorado.

No experience necessary to participate and all are welcome!

The field season runs from May to September, with trainings held in March and April.
