Data presented in the paper: Salt marsh establishment in poorly consolidated muddy systems: effects of surface drainage, elevation and plant age

This data set contains the survival of <i>Spartina anglica</i> seedlings (with different ages), the survival, shoot numbers, plant height and biomass of <i>S. anglica</i> tussocks of a field mega-marsh organ marsh experiment that been carried out in Perkpolder, the Netherlands in 2016 and 2018. This study investigated the impact of surface drainage and elevation relative to mean sea-level on <i>i)</i> the survival of <i>S. anglica</i> seedlings from three different age classes: 1-year, 3-month and 1-week; and <i>ii)</i> the growth performance of mature <i>S. anglica</i> marsh tussocks.

本数据集包含2016年至2018年在荷兰佩尔普尔德（Perkpolder）开展的野外大型盐沼试验的相关数据，涵盖不同株龄的互花米草（*Spartina anglica*）实生苗存活率，以及该物种丛生植株的存活率、分蘖数、株高与生物量。本研究探讨了地表排水与相对海平面高程对两类对象的影响：i）三个不同龄级（1年生、3个月生、1周生）的互花米草实生苗存活率；ii）成熟互花米草丛生植株的生长表现。
