Samenvatting

Salt marsh stability from 10 different salt marshes was studied in the Dutch Wadden Sea region and the Scheldt Estuary during October and November 2018. This report elaborates how salt marsh stability is influenced by bioturbation of Orchestia sp., grazing of large herbivores and different soil and plant properties. The effect of the bioturbating Orchestia sp. was studied by comparing the presence and abundances between determined plots on every salt marsh. Grazed and ungrazed sites were studied whereby differences in grazing type was considered as well.
