About this Event
Field trip in association with the Southern California Botanists to the south end of Temple Hill, Laguna Beach. The trip will focus on Eslinger Ridge, a rocky ridge rising steeply some 800 feet between Aliso and Woods Canyon Wilderness Park and the Pacific Ocean. Eslinger Ridge hosts one of the higher diversities of rare plants in Orange County. The underlying rock is San Onofre Breccia and the vegetation is more typical of Diegan coastal sage scrub and southern maritime chaparral. Among the plants seen will include species more typically seen in coastal San Diego County, including spiny red berry (Rhamnus crocea), bush rue (Cneoridium dumosum), San Diego chamise (Adenostoma fasciculatum subsp. obtusifolium), and summer holly (Comarostaphylos diversifolia).
