Data from: Resilience of beach grasses along a biogeomorphic successive gradient: resource availability versus clonal integration. OecologiaHere, we report on the effects of clonal integration and resource availability on the resilience of two common European dune building grasses (Ammophila arenaria & Elytrigia juncea).This dataset contains data from a field experiment we conducted on the west Frysian barrier island of Schiermonnikoog in the spring and summer of 2017. Full methodology on the experimental set-up can be found in the linked paper. Dataset includes measurements on the regrowth potential of patches of both Ammophila arenaria & Elytrigia juncea after clipping all shoots. In addition we report the soil and plant tissue nutrient levels of all experimental plots.
