Weekly Volunteer Drop-In Program

Volunteers working in a meadow
Help Keep Yosemite Beautiful by Volunteering!
Wednesday Mornings at 9 am

Join our weekly volunteer drop-in program and make a point to give back! The projects include invasive species removal, seed collection, restoration work, and maintaining native plant species. By volunteering, you will help the Division of Resources Management and Science support Yosemite’s biodiversity. Plan to spend your morning outside getting dirty. Here is a great opportunity to spend a few hours with a park ranger while having a hands-on experience in the park.

Volunteers make a difference by helping to protect, preserve, and restore valuable plant and wildlife habitats in Yosemite National Park. Get involved and meet new people, learn from a park ranger, and take an active role in becoming a steward in the park. Whether it’s your first time to the park or you are a returning visitor, come out and make new memories. Volunteering provides a great opportunity to build a more intimate connection with the park.
