The 2025 MeadoWatch season is almost here!
Please print/download all resources needed for your hike on the Volunteer Resources page. Visit MeadoWatch Hike Info for more trail information.

At MeadoWatch, our mission is to engage Mt. Rainier National Park visitors in scientific research to understand how climate change will influence the timing of flowering and seed production in the iconic high mountain meadows pictured above.
MeadoWatch uses a Community Science approach, and volunteers are essential to the success of our program. Every summer, participants hit the trails of Mt. Rainier to record wildflower phenology (the timing of flowering, fruiting and seed production) of some of the most beautiful alpine wildflowers in the world. We use this information to understand which climatic factors trigger flowering and seed production, and how climate change may alter the the timing of seed production. Ultimately, this information can be used to aid resource managers at Mt. Rainier National Park in making conservation and management decisions.
If you are interested in becoming part of MeadoWatch, visit our Get Involved and Volunteer Resources pages for details on opportunities. If you have questions, please drop us a line ([email protected]).
MeadoWatch is Community Science project run out of the Hille Ris Lambers Lab and the Brosi Lab at the Department of Biology at the University of Washington and we work collaboratively with Mt. Rainier National Park.
We look forward to seeing you on the trail!
