This chapter focuses on the changes in epibenthos and demersal fish of the soft substrates in and around the C-Power and Belwind wind farm. The time series graphs from Vandendriessche et al. (2015) were extended and scanned for non-parallelisms between reference and wind farm trend lines. Also size distribution graphs were drawn and analysed. The analyses showed differences between wind farm and reference areas for the period 2013-2014. The positive short-term effects from Vandendriessche et al. (2015) seemed to be a reaction of opportunistic species (i.e. common starfish (Asterias rubens), green sea urchin ( Psammechinus miliaris ), brittle star ( Ophiura ophiura )) since the observed effects disappeared shortly after. The positive shortterm effects on plaice ( Pleuronectes platessa ) and sole ( Solea solea ) could be explained by natural variations in the ecosystem. The earlier reported signals of a ‘refugium effect’ are no longer observed. The decreasing trend for dab ( Limanda limanda Ammodytes tobianus ) displayed episodic increases and short-term positive effects on juveniles. No long-term sandeel trends were visible. Long living species were not yet encountered but may get a chance to establish and recover with the expansion of the wind farm area to a large continuous no-trawling area.
