Mowed and Unmowed Wyoming Big Sagebrush: Foliar Cover by Species, All Transects and Years

Absolute foliar cover data by species from mowed and unmowed Wyoming big sagebrush habitat in Nevada and eastern California. Each row is a unique transect from an individual year. The first two letters in the Transect_ID column represent a unique mowing project. The number following these letters represents a unique replicate within a single project. The fourth character in the Transect_ID column is either a C, indicating unmowed sagebrush (control), or an M, indicating mowed sagebrush. Data were collected at two transects per treatment replicate, with each transect represented by a 1 or a 2 preceding the underscore. The year of data collection is the last four digits of the Transect_ID. For example, cell 2A represents Austin Mow, replicate 2, unmowed transect 1, from 2012. Each column represents the absolute foliar cover of a particular species, genus, or functional group using NRCS plant codes. An _D following a shrub code indicates that that shrub was dead.

本数据集收录美国内华达州与加利福尼亚州东部刈割组与未刈割组怀俄明大艾草（Wyoming big sagebrush）生境中各物种的绝对盖度（absolute foliar cover）数据。每一行对应单个采样年份下的一条独立样带（transect）。样带ID（Transect_ID）列的前两位字母代表唯一的刈割项目，字母后的数字代表该项目内的唯一重复样地（replicate）；样带ID的第四个字符为C或M，其中C代表未刈割艾草对照样地（control），M代表刈割艾草样地。每个处理重复设置两条样带，下划线前的数字1或2用于区分同重复单元内的两条样带；样带ID的最后四位数字即为数据采集年份。例如，单元格2A代表2012年奥斯汀刈割项目、重复样地2、未刈割样带1的采样数据。各列分别对应采用美国自然资源保护局（Natural Resources Conservation Service，NRCS）植物编码的特定物种、属或功能群的绝对盖度；若灌木编码后带有后缀_D，则表明该灌木为枯死亡株。
