The influence of grazing on comparisons between pre-existing and restored saltmarshes

Comparisons between saltmarshes restored through managed realignment (MR) and pre-existing reference sites might be influenced by livestock grazing. This study assessed the vegetation and sediment properties at four sites: two MR sites, a grazed reference site and an un-grazed reference site. Results indicate the grazed reference site had the lowest canopy wheight and biomass, whereas the MR sites had differences in sediment properties in comparison to the pre-existing sites. The role of grazing in MR is discussed, identifying that further research is required to evaluate the temporal influence to inform assessments and the post-breach management of MR sites.
