April Wildflower Report

25 April 1998, Spring Canyon, Otay Mesa—Gladys Baird
A report on the CNPS field trip

Spring Canyon is the City of San Diego's mitigation bank for vernal pools and maritime succulent scrub. The field trip was led by Keith Greer (City planner).

After visiting the mitigation bank, we crossed to the north side of the highway to visit vernal pools Pardee is creating. The project is mitigation for vernal pools that were impacted by their residential development. Scott McMillan, Recon botanist, led us through the steps taken to create the pools.
