Golden Gate has currently targeted the 22 most invasive non-native species for control. These species include: Monterey pine, blue gum eucalyptus, Monterey cypress, black acacia, thoroughwort, cotoneaster, helichrysum, Himalayan blackberry, tall fescue, European harding grass, French and Scotch broom, Cape ivy, Ox-eye daisy, pampas grass, yellow star thistle, periwinkle, gorse, capeweed, English ivy, and calla lilies. These invasive plant populations are considered under control due to a decade of volunteer, staff and grant expenditures. And despite the extensive urban perimeter around the park, only two new invasive species have established small populations within the park within the last decade.

Serpentine soils are home to many rare and endangered plants because they lack nutrients and contain metals toxic to plants--conditions that have led to special adaptations in the plants that can survive on them.
