| Abstract |
To develop more mainland salt marsh. in 2001 the first summerpolder of 135 ha was de-embarked in Noard- Fryslân Bûtendyks (Wadden Sea, province of Fryslân). The main subject is to monitor and analyse surface-elevation and vegetation development in the new salt marsh. In this contribution the results after two years. Sedimentation on the surface is the highest near the (artificial) creeks in ungrazed parts. Halophytes have rapidly invaded the area at the expense of less salt-tolerant plant species. Based on the vegetation development the projed appears to be successful within two years after de-embankment.The projed area is (temporarily) less used by grazing Barnacle- and Brent geese. Due to the large areas of surrounding salt-marsh and grassland outside the Delta dike, the agriculturalland nearby is not affected by higher geese densities. The suitability for breeding coastal- and meadovvbirds dropped, but already shovvsa slight improvement for a few species. |
