Frogs well-off due to nature friendly bank control
In the ditches, the amphibians were counted. The effect of the control in relation to the distance of the nature resort was also studied.
The researchers discovered more kinds of amphibians in the ditches that were controlled nature friendly than in the other ditches. Frogs spread from nature areas in the western peat moor area much easier via ditches with a nature friendly bank control than via ditches without this control. Nature areas can thus be a source of bio diversity for the surrounding agricultural lands.
