Citizen Scientists needed for monitoring butterflies!

The Cascade Butterfly Project (CBP) is a long-term citizen science project monitoring butterfly abundances and plant flowering times in subalpine meadows of the Washington Cascades. North Cascades National Park initiated the project in 2011 to document the effects of warming climates on subalpine ecosystems. 

2020 will be the 10th year of the project and we will focus our efforts on 8 of the original 10 surveys sites: 

  • Skyline Divide and Sauk Mountain in Mount Baker Snoqualmie National Forest
  • Cascade Pass in North Cascades National Park
  • Maple Pass in Okanogan-Wenatchee National Forest
  • Mazama Ridge, Sunrise Rim, Skyscraper Mountain, and Naches Loop in Mount Rainier National Park

Each survey site is monitored at least one time per week throughout July and August. Survey routes are 1-kilometer in length and are located along designated trails. All butterflies observed along the trail are identified to species and counted during the survey. Also, flowering patterns of about 10 plant species are recorded on each route.

We are looking for volunteer citizen scientists to surveys sites throughout the summer. Volunteers work in small groups (2 – 4 are best).

If you are interested in the program, please contact:

Regina Rochefort at or She will put you on the CBP e-mail list for announcements and training.

Volunteers specifically interested in the Naches Loop route can contact Melanie Weiss directly at

Field trainings are tentatively scheduled for:

July 8, 10-2 at Sauk Mountain, Mount Baker-Snoqualmie National Forest

July 15, 10-2 at Sunrise in Mount Rainier National Park
