More Trees Please: A Canopy Webinar Series

While our urban forests are threatened by both climate change and rapid urbanization, they’re also part of the solution. Trees — the backbone of nature in our urban areas — sequester carbon and provide many other environmental and public health benefits. We need to protect and plant more trees in our cities, but which trees, and where, and how? This webinar series, launched in 2020, offers guidance from Bay Area experts on ways to ensure resilient urban forests, providing useful tools to decision-makers, from elected officials to city planners, arborists, tree growers, and landscape architects. View past webinars > >

This program is made possible by a generous grant from the County of Santa Clara Office of Sustainability.

Greening the Outdoor Classroom: Bringing Nature to School Campuses

Thursday, May 20, 2021 | 10:00 – 11:30 AM

Increased use of outdoor learning spaces is top of mind for schools due to limitations posed by Covid-19 on indoor classroom use. In addition to reducing virus risks, outdoor learning benefits students’ social, emotional, and mental well-being. Research shows that trees and gardens create better learning environments for students by alleviating mental fatigue, improving attention, and encouraging hands-on learning outdoors — all of which can bolster academic performance.

In this webinar, learn strategies for bringing trees and nature to school campuses and students of all ages. Find out how to design for success by anticipating roadblocks, identifying feasible opportunities, and engaging with key stakeholders.

You will need to register to view the video.
