Data underlying the publication: How grazing management can maximize erosion resistance of salt marshes

This dataset contains the data obtained and utilized for the manuscript: How grazing management can maximize erosion resistance of salt marshes. The aim was to determine how salt marsh management (i.e., grazing by large vs. small grazers vs. artificial mowing), marsh elevation and marsh age affect soil stability (i.e., soil-collapse) and intrinsic lateral erodibility of salt marshes (i.e., particle-by-particle detachment). For this, soil cores were collected in high and low marshes (above and below 0.5 m MHWL respectively) of different ages. At these locations, we compared cores from grazed areas to cores inside grazer exclosures, with and without artificial mowing. The samples were exposed to waves in waves tanks and erosion was measured. The dataset includes i) the files with the erosion calculation, ii) the soil elevation measured inside and outside the exclosures, iii) a table with all the values of the vegetation and sediment variables measured for the samples with sandy subsoil and iv) a table with all the values of the vegetation and sediment variables measured for the fine-grained samples only

本数据集支撑研究论文《放牧管理如何最大化盐沼（salt marshes）抗侵蚀能力》，收录了该研究获取并使用的全部相关数据。本研究旨在明确盐沼管理措施（即大型牧食者、小型牧食者放牧与人工刈割的对比方案）、沼泽高程以及沼泽发育年限，对盐沼土壤稳定性（即土壤崩塌特性）与固有侧向侵蚀性（即逐颗粒剥离过程）的影响机制。为此，研究人员在不同发育年限的高潮位沼泽与低潮位沼泽（分别对应平均高潮位（Mean High Water Level, MHWL）以上0.5米和以下0.5米的区域）采集土芯。在上述采样点位，研究人员对比了放牧区域与牧食者排除区内的土芯，其中牧食者排除区包含人工刈割与未刈割两种处理。随后将采集的样品置于波浪水槽（waves tanks）中施加波浪作用，并对侵蚀过程进行量化测量。本数据集包含以下内容：i）侵蚀计算相关文件；ii）牧食者排除区内外的土壤高程测量数据；iii）含砂质底土样品的植被与沉积物变量全量数据表；iv）仅针对细粒沉积物样品的植被与沉积物变量全量数据表。
