Ketenisse wetland - small scale tidal wetland restoration in the brackish part of the estuary

Impact on ecosystem services

Step 1: Involved habitats
The measure Ketenisse wetland in the oligohaline zone of the Scheldt estuary was about the creation of intertidal habitat by transforming adjacent land into mainly intertidal flat habitat with a high change in the habitat quality.

Ketenisse is a former intertidal brackish marsh located in an industrial area. After restoration an open brackish tidal area of 60ha (of which 35.5 ha restored) was created along 4km of the river. In the more upstream part of the G section a steep cliff, with a height between 0.3 and 1.5m developed over a length of 100m (Figure 3) (Van den Bergh 2005, Van den Neucker et al. 2007). The cliff is under strong pressure of erosion and moves land inwards.

Step 2: Expected impact on ecosystem services, compared with targeted ecosystem services, and expected impact on beneficiaries

More information about the methodology and the correct interpretation of the results could be found in the overall measures report (Saathoff et al. 2013).

(1) Overall expected impact on ES: From the ES assessment it is concluded that this measure generates overall a positive expected impact for many ES, mainly for “biodiversity”, cultural service (Inspiration for culture, art and design), and regulating service (Erosion and sedimentation regulation (by water bodies)).

(2) Expected impact on targeted ES: The expected impact for the development target “biodiversity” is positive.

(3) Expected impact on beneficiaries: The expected impact for the different beneficiary groups is overall slightly positive, with a positive expected impact for future use.
