Watershed Stewards

Evelyn Barajas-Perez

Watershed Steward


Evelyn Barajas –Perez graduated from the University of California, Riverside in 2015, majoring in Biology.

Afterwards, Evelyn began working in a conifer lab with Dr.  Jeff Diaz and grew an appreciation for nature. It was then that she decided to pursue a career in helping people; but, not by diagnosing illnesses but by protecting the home of all humans, Earth. This led to her applying to the Watershed stewards Program to which she was placed at the San Joaquin River Parkway site. Now she is placed at the San Luis Obispo Steelhead initiative continuing on with her second year in the WSP program.
