Native and nonnative plants grow alongside one another throughout this site. Some are remnants of the grand gardens that were planted during the estate and college periods. Others, like French broom and Eurasian blackberry, are invasive and must be carefully controlled to prevent damage to native habitats.
Midpen has chosen to keep a few culturally significant ornamental plantings, while restoring native species across much of the site. Healthy native landscapes support native wildlife better than degraded ones. Habitat restoration is especially important in open space preserves, which help create linked habitat corridors where wildlife can roam freely from one part of the Bay Area to another.
Volunteer programs at Midpen vary from one day, hands-on stewardship projects ideal for busy people looking for brief, but meaningful ways to get involved, to long-term commitments for individuals interested in developing a deeper connection to Midpen’s mission of land preservation and ecologically sensitive public enjoyment.
