Watershed Education and Bio-Fertilization Workshop

Watershed Education and Bio-Fertilization Workshop

June 20th, 10:30-11:30 AM, Lake Park

HumiliTree's Owner & Lead Designer, Tanner Petrilla, will lead a hands-on participatory workshop, introducing the science and practice of homemade biological fertilizers — and demonstrate direct application to trees at Lake Park. This workshop is designed to be accessible to community members and land managers alike, rooted in peer-reviewed science without the jargon. Daniel Moss, from the City of Reno, will discuss the Stormwater Committee's efforts to improve the Truckee Meadow's overall watershed health, future watershed restoration projects, and how citizens can prevent stormwater pollution within their neighborhoods.

To enjoy the workshop comfortably - bring your favorite camping chair or picnic blanket.

Optional: Before the workshop, join One Truckee River and Friends of Lake Park in cleaning up and beautifying Lake Park. Click here to sign up to volunteer from 8:30-10:30 AM.
