Fostering river continuity on the Danube and tributaries to

Continuitiy of the rivers is disrupted on many ways. Sometimes this is invisible for humankind such as in the case of bridges or light pollution which are huge barriers in breeding of Danube mayflies. These animals came back to the Upper Hungarian Danube stretch only for ten years since before water quality of the Danube was not approppriate for them. Thereafter they had new challenges in survival.
First planned action is to make an ivestigation where exactly the problem emerges, on which river sections, which countries. Then it is a need to take a stock on new bridge plans and existing bridges or those light sources which can be an obstacle for the mayfly.
Thereafter all responsible authorities should be involved to find solutions which can be putting new specific light sources on the existing bridges and planning of new ones with this specific light. Also a shutting down of the street lighting next to the river would be a solution where relevant. Involvment of the inhabitants of the cities can be realized with saving of Danube mayfly actions. Also, it has an excellent communication potential, through which value of the river and floodplain ecosystem can be recognized.

Goal is to save this protected and indicator species and its habitat, healthy, natural river conditions, to involve people into saving actions and to show inhabitants value of rivers.
