Corona Heights Description
Corona Heights is one of the oldest of the habitat restoration projects. Randall Museum staff and local neighborhood activists began removing weeds from the summit grasslands back in the early 1990s. Corona Heights became an official GLS activity of the San Francisco Bay Chapter of the Sierra Club shortly thereafter. Since 1999, the project has been led by the Natural Areas Program.
Initially the principal weed targets were large invasives — radish, broom, and fennel. After years of regular removal, these pests are largely under control, and smaller, more difficult-to-handle weeds are our primary concern — plantain, sheep sorrel, oxalis, and ehrharta grass. Here is the management plan.
Over the years, volunteers planted many native grasses and forbs, but the survival rates were feeble at best. The main problem turned out to be trampling and digging by the numerous off-leash dogs that owners allow to roam (illegally by the way) around the summit. These dogs go after the many voles and gophers that live in the grasslands, and there go the new plants. However, during the past four years we’ve begun to place short temporary fences around new plantings, and survival has been well over 50% now.
Corona Heights currently has 64 volunteers who have subscribed to our regular email newsletters and work at this site. They have posted 56 photos and 18 posts to their blog.
