Sufficient water levels and calmness at the breeding sites are the best protection for breeding and rearing. Low water levels allow wild pigs and foxes to reach the nests and feed the eggs. In some cases, breeding cranes were even killed by foxes while sleeping. This shows the importance of wet areas for the survival of cranes. If the water level is too low, better conditions can be achieved by retaining water and other regulating actions.
The activities of human beings (forestry, agriculture, hunting, tourism) pose a potential threat: Cranes are highly sensitive during the breeding period and can give up their nest when they are disturbed. Therefore the interference by human beings is often regulated by law, for example the nest protection zones in Mecklenburg-Western Pomerania and Brandenburg. In addition, the committed people from Crane Conservation Germany who take care of the breeding sites as well as programs for the protection of wet areas by NABU and WWF help to implement different protection measures on local level.
The most important premise for an efficient protection is the trustful teamwork between land owners, foresters, farmers and hunters as well as the officials and volunteers for nature conservation.
