Checkered Gartersnake Predicted Habitat - CWHR R065 [ds2445]

CWHR Predicted Habitat Suitability. This dataset represents areas of suitable habitat within the species ranges based on California Wildlife Habitat Relationships (CWHR 2016) and a statewide best-available vegetation map (FVEG2015, FRAP 2015). Habitat suitability ranks of Low (less than 0.34), Medium (0.34-0.66), and High (greater than 0.66) suitability are based on the mean expert opinion suitability value for each habitat type for breeding, foraging, and cover.

Please note that the data is represented in raster format with a pixel size of 30 meters. In the case of species that rely on habitat types that are difficult to map at this scale, such as riparian or wetland habitat types, the amount of representative habitat may be underestimated or inaccurately mapped due to aggregation into pixels with a majority type not used by the species.

CWHR预测栖息地适宜性数据集。本数据集基于加州野生动物栖息地关系（California Wildlife Habitat Relationships，CWHR 2016）与全州最优可用植被图（FVEG2015、FRAP 2015），刻画了物种分布范围内的适宜栖息地区域。栖息地适宜性等级分为三级：低适宜（得分<0.34）、中适宜（得分0.34~0.66）与高适宜（得分>0.66），其划分依据为各栖息地类型在繁殖、觅食及隐蔽需求上的专家意见适宜性均值。

请注意，本数据集采用栅格格式存储，像素尺寸为30米。对于依赖河岸或湿地等难以在此分辨率下精准制图的栖息地类型的物种而言，由于栅格聚合后多数像素的主导类型并不符合物种的栖息需求，因此该类物种的代表性栖息地面积可能被低估，或出现制图不准确的问题。
