There are few if any marine areas left in the world that are not affected by human pressure. Human activities affecting flads are for example ditching and cutting forests as well as dredging and construction in the flads. All these activities affect the water quality in the flads and further the whole ecosystem. Dredging especially in the mouth area of the flad can have large effects on the water exchange in the flad and therefore the temperatures. This kind of changes can have tragic effects on the flads functioning as a reproduction area for perch and pike as the temperatures plays a huge role for their reproduction.

One of the main goals in the project is to test restoration methods in flads and restorate four flads. These restauration activities should result in local improvement of the reproduction area for the fish.
