Black Toad Species Habitat Model (Categorical) - NatureServe [ds3266]

This Species Habitat Model was produced by NatureServe to predict the habitat distribution for Anaxyrus exsul (Black Toad). The data represents predictions of suitable habitat based on relationships of species occurrences with environmental predictors across the model area. NatureServe includes two standard spatial outputs for Species Habitat Models. The continuous predictions map is a spatial layer with values from 0 to 1, indicating relative likelihood that habitat occurs at a given location. The categorical predictions map indicates the likelihood of habitat as distinct classes (e.g., high, medium, low, and not habitat). These outputs should not be interpreted as a direct estimate of species presence or absence. For more information about the methodology and the model metadata, please contact Nature Serve at [e-mail]. Model created by NatureServe on: 04/25/2019. Revisions completed by California Department of Fish and Wildlife on: 09/23/2025.本物种栖息地模型（Species Habitat Model）由自然保护协会（NatureServe）研发，旨在预测黑蟾蜍（Anaxyrus exsul）的栖息地分布。本数据集所呈现的适宜栖息地预测结果，基于研究区域内物种出现记录与环境预测因子之间的关联关系生成。自然保护协会为物种栖息地模型提供两类标准空间输出产物：连续型预测图为取值范围0至1的空间图层，用以表征给定位置存在适宜栖息地的相对可能性；分类预测图则将栖息地适宜性划分为高、中、低及非栖息地等明确等级，以表征对应适宜性水平。上述两类输出均不可被直接解读为物种存在或缺失的直接估算结果。若需了解模型方法学与元数据的更多详情，请致信自然保护协会：[e-mail]。本模型由自然保护协会于2019年4月25日创建，加州鱼类与野生动物局（California Department of Fish and Wildlife）于2025年9月23日完成修订。
