University staff and Osborn Naturalists


No commitment required to join this event! The flexible requirements to become an Osborn Naturalist include joining additional Naturalist Ed Series events and teaming up with experienced naturalists to help co-lead school tours. 

Osborn Naturalists are welcomed into a community of volunteers who work on university research projects, attend special naturalist events and hikes and gain additional access to the Osborn Preserve. Naturalists completing the program receive an “Osborn Naturalist Certificate of Completion.” Join a community working to eradicate Nature Deficit Disorder in the North Bay! Become an Osborn Naturalist and acquire the skills to get “Environmentally Ready.” 

Our program is flexible to fit into your busy schedule. (If you are an SSU Undergraduate student, contact Suzanne DeCoursey at for information about the Student Naturalist Training Program.)

This event is part of the Naturalist Ed Series. The event within this Series allows participants the option to become Osborn Naturalists to address nature-deficit disorder. No experience required. Must be age 18 years or older.


The events within the Naturalist Ed Series are held outdoors at SSU’s Fairfield Osborn Preserve, a 15-minute drive from SSU’s main campus. All events occur rain or shine.

The maximum hike is 2 miles with a 400-foot elevation gain. 

Directions are provided in your registration confirmation email. A sink for handwashing, potable water and restrooms are available on site. Please arrive to park in advance of the registered event start time. The preserve gate will be unlocked 20 minutes before the event start time.
