The two San Francisco populations are on land which is protected from development but is affected by many other factors including invasive plant species, trampling, and landscaping of vegetation. The three Oakland populations are probably the remnants of one population that was fragmented by development in the heavily altered urban habitat.[1] The largest of the three occurrences is partially protected at Redwood Regional Park, but the other two are on privately owned property which is proposed to undergo some development. Construction of housing is proposed on the site, with less than an acre being left undeveloped as a compromise between developers and environmental advocates
