About this Event

Volunteer with Grassroots Ecology and Peninsula Open Space Trust (POST) to support the expansive oak woodlands and grasslands at Pearson-Arastradero Preserve. These ecosystems are home to an abundance of wildlife, including deer, bobcats, coyotes, many species of birds and insects, and more!

During our time together, volunteers will be digging up invasive harding grass and planting native plants in their place. Prepare to dig with shovels and get muddy!

Visit Grassroots Ecology’s Pearson-Arastradero Preserve webpage to learn more about the ecosystem and accessibility considerations.

-

Peninsula Open Space Trust is a nonprofit land trust working to protect open spaces for the benefit of all and connect people to nature in the Peninsula and South Bay. Since 1977, POST has protected over 90,000 acres in San Mateo, Santa Clara, and Santa Cruz Counties. Visit openspacetrust.org for more information.

Join Us!

Grassroots Ecology encourages people from all identities and backgrounds to participate in our programs. Many of our programs are outdoors and involve moving and working in a variety of landscapes. If you have accessibility concerns (e.g. allergies, limited mobility, learning differences), our projects are flexible and we are happy to work with you. Please contact the workday facilitator so we can prepare for your participation.
