Saturday, April 4, 2015, 09:00 a.m.-12:00 p.m.: Santa Fe dam County Regional park: This trip will explore the last of the unique Riversidean alluvial scrub natural community in the San Gabriel Valley. The walk will wind through over 400 acres of terraces of the San Gabriel River flood plain, full of plants and animals that are declining elsewhere. The leader is Mickey Long. This is a joint field trip with Southern California Botanists.
Mickey plans to discuss the ecosystem as a whole: plants, birds, reptiles and the interesting successional vegetation levels tied to river hydrology. California junipers, valley cholla, huge laurel sumacs, giant Whipple yuccas live here, along with Spring wildflower displays in open flats, and resident cactus wrens and migrant birds. We could walk to the site of Los Angeles County’s only Hesperevax acaulis.
Directions: Take the 210 Fwy to the Irwindale Ave off-ramp. Travel south on Irwindale Ave to Arrow Hwy, then turn west to the Santa Fe Dam entrance drive on the right. After the stop at the entrance kiosk (fee approximately $6 per car) turn right (north) following signs to the Nature Center to meet at 9 a.m. in the Nature Center parking lot at the north end of the basin. Wear good sturdy shoes or boots, hat and bring water.
