Description: Aquatic native species richness is a measure of species biodiversity, and is one measurement used to describe the distribution of overall species biodiversity in California for the California Department of Fish and Wildlife (CDFW) Areas of Conservation Emphasis Project (ACE). Native species richness represents a count of the total number of native aquatic species potentially present in each watershed based on species range and distribution information. The data can be used to view patterns of species diversity, and to identify areas of highest native richness across the state. The species counts consist of four taxonomic groups - fish, aquatic invertebrates, aquatic amphibians, and aquatic reptiles.----------------This raster has been modified from the base 30m version in the following ways:-------- - It has been aggregated from a 30m to a 300m scale by averaging across the 30m values-------- - The normalized values are rescaled based on nearly the full range of actual values, with the most extreme upper values at the 1st and 99th percentile to reduce the influence of outliers on the expressed range of normalized values, with -1 representing zero, and 1 representing high values. This interpretation reflects concerns for conserving aquatic species diversity, with greater richness considered more favorable.----------------- Unit Of Measure: Count
