Red Phalarope Predicted Habitat - CWHR B656 [ds2376]

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《加州野生动物栖息地关系（California Wildlife Habitat Relationships, CWHR）2016版》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。生境适宜性等级划分为低（小于0.34）、中（0.34~0.66）和高（大于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，本数据集采用栅格格式存储，像素尺寸为30米。对于依赖此类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，由于栅格像元会聚合为以多数土地类型为主的单元，而该多数类型并非物种所利用的生境，因此代表性生境的数量可能被低估或制图结果存在偏差。
