Black Bear Habitat Model for NSNF Connectivity - CDFW [ds1008]

Predicted habitat suitability grid developed using Maxent and reviewed by CDFW staff for use in the northern Sierra Nevada foothills wildlife connectivity project. Scenario9: vegetation, distance to water, elevation, and four bioclimatic variables were used to predict habitat suitability. The vegetation data in this scenario was represented by four continuous vegetation datasets (percent conifer, percent grassland, percent hardwood, and percent shrubs). The four bioclimatic variables were: bio01 (Annual Mean Temperature), bio04 (Temperature Seasonality), bio12 (Annual Precipitation), and bio15 (Precipitation Seasonality).

本数据集为采用Maxent模型开发的栖息地适宜性预测栅格，经加州鱼类与野生动物部（CDFW）工作人员审核，用于内华达山脉北部山麓野生动物连通性项目。情景9以植被、距水源距离、高程及4项生物气候变量为预测因子开展栖息地适宜性预测。该情景下的植被数据由4组连续型植被数据集表征，分别为针叶林占比、草地占比、硬叶林占比与灌丛占比。本次使用的4项生物气候变量依次为：bio01（年平均气温，Annual Mean Temperature）、bio04（气温季节性波动，Temperature Seasonality）、bio12（年降水量，Annual Precipitation）以及bio15（降水季节性波动，Precipitation Seasonality）。
