  1. Deposit soil/sediment to form physical structure of freshwater marshes

    A replicated, paired, site comparison study in 2003 around three freshwater lakes in the Netherlands (Sollie et al. 2008) reported that marshes created by depositing sand contained fewer plant community types than natural marshes, but found that they had similar vegetation biomass. After 8–16 years, the created marshes contained three distinct plant community types, compared to four in natural marshes. Unlike natural marshes, created marshes did not contain pure stands of cattails Typha spp. or common reed Phragmites australis. However, the above-ground vegetation biomass in sampled plots did not significantly differ between created marshes (1.5 kg/m2) and natural marshes (1.6 kg/m2). Methods: In August 2003, vegetation was surveyed around the margins of three connected freshwater lakes. One created marsh and one natural (mature) marsh were surveyed in each lake. Created marshes had been formed by depositing sand to a suitable elevation for plants to colonize. Vegetation was cut from three or four 400-cm2 plots/marsh, distributed across the plant community types present, then dried and weighed.
