Plant densities, gaps, and soil cover.

Means ±1 SE for perennial grass densities by species, sagebrush (Artemisia tridentata ssp. wyomingensis) densities by size class, inter-plant gaps by total length in each gap size class, and soil cover types across three herbivore treatments: 1) Total exclosure plots that exclude both cattle and wild ungulates, 2) Cattle exclosure plots that exclude only cattle, and 3) Control plots where no large herbivores are excluded.a #/hab total cmc # pin hits (of 20)Plant densities, gaps, and soil cover.本数据集记录了四项生态学指标的平均值±1倍标准误（Standard Error，SE），具体包括：按物种分类的多年生草本植物密度、怀氏三齿蒿（Artemisia tridentata ssp. wyomingensis，sagebrush）按径级划分的种群密度、各间隙尺寸等级对应的株间间隙总长度，以及三种草食动物处理下的土壤覆盖类型。三种草食动物处理分别为：1）全排除样地：同时排除肉牛与野生有蹄类动物；2）肉牛排除样地：仅排除肉牛；3）对照样地：未排除任何大型草食动物。此外，本数据集还包含以每公顷总量、cmc、针刺采样（Pin hits）的20次采样击中数相关的植物密度、间隙及土壤覆盖类型数据。
