Biome-wide sagebrush core habitat and growth areas estimated from a threat-based conservation design

These data were compiled as a part of a landscape conservation design effort for the sagebrush biome, and are the result of applying a spatially explicit model that assessed geographic patterns in sagebrush ecological integrity and used these results to identify Core Sagebrush Areas (CSAs), Growth Opportunity Areas (GOAs), and Other Rangeland Areas (ORAs). Our overall objective in this study was to characterize geographic patterns in ecological integrity of sagebrush ecosystems. These data represent the estimated integrity of sagebrush ecosystems, estimated from a spatial model that assigns high integrity is areas with abundant big sagebrush and perennial grass/forb cover and with minimal annual grass/forb cover, minimal conifers, [...]

本数据集为蒿灌生物群系（sagebrush biome）景观保护规划工作的一部分编译所得，源于一项空间显式模型（spatially explicit model）的应用结果：该模型评估了蒿灌生态系统的地理分布格局，并据此识别出核心蒿灌区域（Core Sagebrush Areas, CSAs）、生长机遇区域（Growth Opportunity Areas, GOAs）与其他牧场区域（Other Rangeland Areas, ORAs）。本研究的总体目标为刻画蒿灌生态系统生态完整性的地理分布特征。本数据集表征了蒿灌生态系统的估算生态完整性，该估算基于一项空间模型完成：模型将具备丰富大籽蒿灌丛（big sagebrush）与多年生草本/杂类草覆盖，且一年生草本/杂类草覆盖、针叶林占比极低的区域划定为高完整性区域，[...]
