Unofficial or “social” trails form when trail users veer off of official trails while exploring. Unfortunately, social trails can leave lasting impacts on ecosystems. Learn about how these trails affect sensitive habitats at Stulsaft Park.

This spring, our Habitat Restoration Intern Ruby was invited to share her “story of possibilities” with hundreds of people as a closing speaker at the TOGETHER Bay Area annual conference. Read her speech on possibilities in hands-on habitat restoration!

Every spring, Grassroots Ecology staff head off-trail at Pearson-Arastradero Preserve to monitor, map, and remove an invasive annual grass called medusahead (Taeniatherum caput-medusae or Elymus caput-medusae). Grassroots Ecology has been actively managing medusahead here since 2010. Learn why and how we’re managing this invasive species.
