Results/Conclusions: Preliminary results indicate significant differences between the vegetation of remnant and restored tidal marshes surveyed, based on restoration history. Outcomes suggest that remnant marshes are more heterogenous in species composition. In restored marshes, species such as Carex lyngbyei tend to dominate the sites with high frequency of occurrence and percent cover. Salt-tolerant species, such as Triglochin maritima and Sarcocornia perennis are associated with higher salinity/conductivity and low elevation conditions, while high marsh species, including Argentina egedii and Agrostis stolonifera are associated with higher elevations and lower salinities. Marsh surface elevation does not differ significantly among sites that were restored at different times in this estuary. The highest soil salinities occur in mid-marsh elevations where evaporation is higher than for high marsh plots which are only occasionally inundated or plots near the water’s edge (which are inundated at similar frequencies but longer time periods than as mid-marsh). Vegetation of restored salt marshes is significantly less diverse and more spatially homogenous than that of reference sites, even 38 years post-restoration. Site hydrology, time since restoration, and prior land-use history influence the vegetation community composition at Salmon River Estuary.
