Dec 13, 2010 (Last modified May 12, 2011)
This layer contains polygon features of Ecological Units for the state of California as described by ECOMAP (1993),.. "Ecological types are classified and ecological units are mapped based on associations of those biotic and environmental factors that directly affect or indirectly express energy, moisture, and nutrient gradients which regulate the structure and function of ecosystems. These factors include climate, physiography, water, soils, air, hydrology, and potential natural communities."
