Which two specific open space preserves are mentioned as actively supporting SFGS populations while also being managed as cattle ranches?

Answer

Russian Ridge Open Space Preserve (RR) and Cloverdale Ranch Open Space Preserve (CR)

The reality of conservation for the San Francisco garter snake often involves managing 'working landscapes' rather than exclusively pristine wilderness areas, meaning human land use must be accommodated. Two specific preserves are cited as examples where extant populations thrive despite or because of managed land use: the Russian Ridge Open Space Preserve (RR) and the Cloverdale Ranch Open Space Preserve (CR). Both of these areas are actively managed as cattle ranches. This grazing, when kept below an overgrazing threshold, has been positively linked to maintaining the open grassland/shrub matrix that the snakes prefer for basking and movement between aquatic and terrestrial zones.
