Layer: Wildlife Species Richness normalized (ID: 108)

Parent Layer: Species Diversity

Name: Wildlife Species Richness normalized

Display Field:

Type: Raster Layer

Geometry Type: null

Description: Native species richness is estimated based on high suitability reproductive habitat for a given species. Reproductive habitat is used to represent suitability because it is critical for species persistence and for most native species it has the most limited requirements. If a habitat is identified as high for a given species, it is considered suitable (1), and habitat identified as moderate, low or not suitable, it is considered unsuitable (0). Species richness values are used as a relative measure of biodiversity value; as such, areas with lower species richness based on these criteria may still have high biodiversity value, but not as high as areas with higher richness values. The number of native species per spatial unit (30m pixel) presented as simply the total number; this can be useful for assessing change in number/composition over space.----------------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 concern for declines in species diversity as a function of richness, with richness values considered more favorable.----------------- Unit Of Measure: Number of species
