Taxonomy

Franciscan manzanita was formerly considered as a subspecies of Hooker's manzanita until elevated to full species rank following modern genetic analysis and comparisons.[3]

Conservation

When the Laurel Hill Cemetery in San Francisco was bulldozed in 1947, it was thought that the Arctostaphylos franciscana went extinct.[4][5] In 2009, one wild specimen of the shrub was discovered in the Presidio by a local conservationist.[6][7] The land the plant was found on was part of the Caltrans Doyle Drive Replacement Project and was not protected, which prompted litigation.[8] The single shrub found was moved and was used to try to reproduce the species.[8]

The U.S. Fish and Wildlife Service designated the Franciscan manzanita as an endangered species on October 5, 2012.[9][10][11] The National Park Service and Golden Gate National Parks Conservancy are attempting to cross-pollinate and propagate the preserved specimen in order to reintroduce the subspecies in the wild.[12][13]
