Vernal pools in five counties along the California central coast (Monterey, San Benito, Santa Barbara, San Luis Obispo, and Ventura counties) were mapped from one-meter resolution digital orthophoto quadrangles from USGS.
Presents findings from comprehensive mapping of vernal pool habitats in the five county region.
Pools were mapped from doqqs, mostly base on 1994 air photos. Mapping from doqqs subsequently was checked against 10-meter resolution SPOT cover taken during summer, 2000. Twenty five percent subsample visited in the field during September.
