White-winged Dove Predicted Habitat - CWHR B254 [ds2172]

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。本数据集基于《加州野生动物生境关系（California Wildlife Habitat Relationships，CWHR 2016）》及全州最优可用植被图（FVEG2015、FRAP 2015），表征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（适宜值小于0.34）、中（0.34~0.66）与高（适宜值大于0.66），该等级依据各生境类型在繁殖、觅食及隐蔽方面的专家意见适宜值均值确定。

请注意，本数据采用栅格（raster）格式存储，像素分辨率为30米。对于依赖难以在此空间尺度下精准制图的生境类型（如河岸或湿地生境）的物种而言，由于数据会被聚合至以多数类型为主的像素单元中，而该多数类型并非该物种所利用的生境，因此其代表性生境的面积可能被低估或制图不准确。
