Based on information, it is expected that the ecological connection zone in the Goorloop will affect water values in such a way that the biodiversity will increase. An increase in biodiversity is expected to be seen in the ecological connection zone, but not in the other two regions outside the connection zone.
The results show that the water values and organisms found in Sang & Goorkens, the ECZ and ‘t Groot Goor do in fact differ from each other.

The ecological connection zone has a slightly lower pH than Sang & Goorkens, 6.93. The pH is still fairly neutral. This is ideal for fish, amphibians and water plants. The dKH, NO3-, NO2-, NH4+ and turbidity all suggest that the water in the ecological connection zone is very clean. More species were found in the ECZ than in Sang & Goorkens. The animals living in the ECZ usually live in freshwater, which suits with the water values. The plants that were found do not live in typical environments, so no conclusion can be drawn from that.

The most species were found in the ECZ, this confirms the hypothesis that the ecological connection zone would have a positive impact on the biodiversity in the Goorloop.
