Volunteer of the Month


Land Steward

Encouraged by a friend to volunteer locally, Ryan discovered Open Space Authority volunteer events through Twitter and has been a dedicated member of the team ever since! 

"Volunteer events have allowed me to take a purposeful break from my laptop, my stay-at-home remote work, and enjoy being productive in the outdoors.” 

His favorite program is Land Stewards Fourth Saturdays at Sierra Vista’s Furtado Barn Restoration Area, which is the first event he ever attended. 

“It's been great to learn more about the site with each new restoration activity... I feel like I'm always learning something new regarding ecological restoration, from invasive plant identification and removal, to native planting, a bit about the history of the area, to various techniques used to restore the land.” 

When not volunteering, Ryan enjoys reading, hiking, and camping.
