Vegetation - Napa County and Blue Ridge Berryessa [ds201]

Physical and biotic conditions, along with site history, drive the composition of plants found at any site. Therefore, vegetation represents a unique biotic response to local environmental conditions at a site. Vegetation composition is in turn a major factor in determining what animals may be present. Because of the interactions between environment, plants, vegetation and community structure, vegetation distribution has long interested ecologists and natural resource managers. Documenting regional vegetation is useful for many purposes, including biodiversity assessment, conservation planning, resource management, and species distribution modeling.
