Cataloging observations in and around Sobrante Ridge Regional Preserve in the Hills of Richmond/El Sobrante. The Preserve has a two acre heart that we call the 'Manzanita Grove'. There are also grasslands and coastal scrub and oak woodland habitats. There are also several riparian areas. The preserve has a trail system that mostly follows the service/fire road. A single track trail explores the manzanita areas. There are use-trails that visit the grassland summits. Vicinity, for purposes of this project, I define as the wild lands and human neighborhoods bordering the preserve and the skies above and within eyeshot from the preserve. menos ↑
