Skilled volunteers are needed to inventory the plant life in the Tuolumne Wild and Scenic River corridor. Help is needed to identify the vascular plants, collect voucher samples and take high quality representative photographs of the species found. Skills needed include the ability to identify plants using standard plant keys, ability to hike the trails along the river, and/or digital photographic skills and equipment. Experts in bryophytes, lichens or fungi are also desired. The time commitment and work schedule are completely flexible and up to the wishes of each volunteer.
