Summary

Calculate loss and gains of vernal pool habitat between 2005 and 2010 in Merced County, California.

Description

We mapped vernal pool distribution within a 21.4 million acre area surrounding the Great Valley from 2005 National Agricultural Imaging Program (NAIP) county photomosaics using ESRI ArcMap 9.x in a double-blind protocol. Each mapped polygon was scored for classes of habitat cover, habitat density, habitat diversity, disturbance cover, and disturbance intensity. We remapped Placer, Sacramento, and Merced counties using 2010 NAIP imagery to calculate rates of habitat loss and gain in the five years since the Vernal Pool Recovery Plan was released. The source of loss or gain was identified for each polygon.
