Extent of U.S. Rangelands

This raster dataset depicts rangelands in the coterminous U.S., including transitional rangelands and small patch-size rangelands. Each 30 meter pixel is assigned a land cover category, including Rangeland, Afforested Rangeland (experiencing encroachment by trees [> 25% tree cover]) and Transitional Rangeland (currently dominated by herbs or shrubs that will likely become forested without management intervention). The dataset can be downloaded from the following website: https://data.fs.usda.gov/geodata/rastergateway/rangelands/index.php Note: To download this raster dataset, go to ArcGIS Open Data Set and click the download button, and under additional resources select raster download option. An image service that depicts rangelands in the coterminous U.S., including transitional rangelands and small patch-size rangelands.本栅格数据集（raster dataset）展示了美国本土48州（coterminous U.S.）的牧地（rangeland）分布，涵盖过渡型牧地与小斑块牧地。每个30米分辨率的像素均被赋予一类土地覆盖类型，包括牧地（Rangeland）、造林牧地（Afforested Rangeland，即正遭受树木入侵、树木覆盖率＞25%的区域）以及过渡型牧地（Transitional Rangeland，当前以草本或灌木为优势植被，若无管理干预，未来将自然演替为森林）。本数据集可通过以下网址下载：https://data.fs.usda.gov/geodata/rastergateway/rangelands/index.php。注意：下载该栅格数据集时，请进入ArcGIS开放数据集页面，点击下载按钮，并在附加资源中选择栅格下载选项。另有一款影像服务可展示美国本土48州的牧地分布，涵盖过渡型牧地与小斑块牧地。
