	\|~~Name~~ of ~~parent multi-site project~~=~~Building with nature measures~~ in ~~streams~~		\|Project summary=The Grote Aa was part of an experiment on the effect of vegetation removal on flow velocity variation and the abundance of fish and macroinvertebrates. For this experiment, different stretches of the stream were given a different treatment: the vegetation was either only mowed in blocks on one bank or only mowed in the middle of the stream. Both experiments were performed for a one year period in one stretch and a two year period in another stretch, so it could be determined how the vegetation, fish and macroinvertebrates would respond over various periods of time.
			\|Monitoring surveys and results=Immediately after mowing, variation in flow velocity was observed and the fish population increased. However, the effect on water quality was very small. The water has remained eutrophic and the existing domination of floating vegetation was not broken. Instead, the species that were already abundantly present covered a larger area two years after mowing. The composition of the macroinvertebrate population differed between mowing regimes in the first year of the experiment, but showed a return to normal conditions in the second year.
