The trail to Indian Knob, the tallest of the hills south of San Luis Obispo, starts on the Guidetti Ranch near the airport. Access to this area is restricted to a few hikes a year, sponsored by EcoSLO. As native plant enthusiasts, the goal of these hikes, in addition to enjoying the oak studded property and a 360o view at the top, is your chance to view one of the rarest plants in this county, the Indian Knob Mountain Balm, Eriodictyon altissimum. According to the US Fish and Wildlife Service: when this plant was federally listed as an endangered species in 1994, there were fewer than 600 individuals known to exist. The Pismo clarkia, Clarkia speciose, ssp. immaculate, also occurs along this trail. Both of these species are listed by CNPS as extremely rare 1B.1 plants.
Please RSVP the EcoSLO docent listed below to hold a place for the hiking date that suits you and to receive more information about the hike.
