Coachwhip Predicted Habitat - CWHR R052 [ds2432]

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预测生境适宜性数据集。本数据集基于加州野生动物生境关系（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生境区域。生境适宜性等级分为低适宜（得分低于0.34）、中适宜（得分0.34~0.66）与高适宜（得分高于0.66），其划分依据为各生境类型在繁殖、觅食与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（raster）格式存储，像素分辨率为30米。对于依赖该尺度下难以精准制图的生境类型（如河岸或湿地生境）的物种而言，由于栅格聚合后多数像元的主导生境类型并非物种所需，其代表性生境的面积可能被低估或制图失准。
