Annual precipitation and photo-derived vegetation and litter cover (2013-2021) used for analysis in the manuscript “Growing grasses in the desert: Multi-scale Interactions and State Change Reversal in Drylands”

This dataset contains water year precipitation collected from meteorological stations, litter and vegetation cover values derived from overhead photos, and litter and soil accumulation in lateral photos in a long-term experiment (2013-2021) of cross-scale interactions (CSIs) at the Jornada Basin LTER site in southern New Mexico, U.S.A. Manipulations were initiated in 2013 at 15 experimental blocks, each with 4 treatment plots: plant-scale herbicide of mesquite shrubs, patch-scale connectivity modifiers (ConMods), herbicide + ConMods, control without manipulations. Litter, soil, and vegetation cover were estimated using repeat overhead photographs of microplots within treatment and control plots. Litter and soil accumulation were estimated from lateral photos of ConMods. This dataset utilized QuickBird imagery from 2011 to assess ground cover classes within the Jornada Basin, focusing on bare ground, herbaceous, and shrub cover. Daily precipitation data collected from 13 meteorological stations were used to calculate water year (1 October-30 September) precipitation from 2013 through 2021. This dataset provides supporting data for the manuscript "Growing grasses in the desert: Multi-scale Interactions and State Change Reversal in Drylands" by Peters et al.

本数据集涵盖美国新墨西哥州南部霍拉迪盆地长期生态研究（Long-Term Ecological Research, LTER）站点2013-2021年跨尺度交互（Cross-scale Interactions, CSIs）长期试验的多类数据：气象站采集的水年降水量、正射影像衍生的枯落物与植被覆盖值，以及侧拍照片中的枯落物与土壤堆积量。
该试验于2013年在15个试验区组中启动，每个区组包含4个处理样方：牧豆树灌丛的植物尺度除草剂处理、斑块尺度连通性调节剂（Connectivity Modifiers, ConMods）处理、除草剂与连通性调节剂联合处理，以及无任何干预的对照样方。
枯落物、土壤与植被覆盖通过处理样方与对照样方内微型样地的重复正射影像进行估算；枯落物与土壤堆积量则通过连通性调节剂的侧拍照片完成评估。
本数据集还利用2011年的QuickBird影像对霍拉迪盆地内的地表覆盖类别进行分类，重点覆盖裸地、草本植被与灌丛覆盖三类地表类型。
研究团队通过13个气象站采集的日降水量数据，计算得到2013年至2021年的水年（10月1日至次年9月30日）降水量。
本数据集为Peters等人发表的论文"Growing grasses in the desert: Multi-scale Interactions and State Change Reversal in Drylands"（中文译名为《荒漠种草：旱地多尺度交互与状态逆转》）提供支撑数据。
