The exotic plant Crassula helmsii poses a risk, as it might dominate other species. So far, grazers have not been sufficient for removing undesirable vegetation. Trees need to be cut regularly. 26318 In progress De Doorbraak is a newly created stream near Almelo. Its creations has several purposes. In terms of water quantity, the stream helps create more space for inundation, so that there is less of a need to discharge water out of the area. This is supposed to help retain more water in the region in wet periods and prevent drought in dry periods. De Doorbraak is also part of a plan to improve the water quality of the Regge basin. It contributes to a separation of urban and rural waters, so that less polluted water ends up in the Regge. To achieve this goal, an underpass is created in the Twentekanaal, so that its more polluted water does not mix with the cleaner Doorbraak water. Finally, this stream provides and ecological link between Twente in the northeast and the hills of the Sallandse Heuvelrug in the southwest. The topsoil of this stream valley was removed over a length of 13 km and a width of 50 m. This created a large area that the stream can inundate. Abandoned meanders and pools were conncted to the main stream. Vegetation removal is managed by grazers, with additonal mowing, if necessary.
