The Pinkerton Prize for Outstanding Student Contributions to the UC Davis Arboretum and Public Garden was created in the early 1990s by Bret Hewitt and his late wife Deborah Pinkerton, the first environmental education employee at the Arboretum and Public Garden. The prize honors exceptional Learning by Leading™ students participating in our environmental education programs. The 2021 award winners were Aliciá Ayala, Anita Shahriary and Laura Gomez.
