Wolves and lynx could be used to reduce the number of deer in the dune area west of Amsterdam, says the city’s water board Waternet, according to news agency ANP.

Waternet, which uses the dune area to filter the city’s drinking water, says lack of natural predators is boosting the deer population by around 30% a year.
There are now some 1,500 deer in the area. Last year there were 13 road accidents involving the animals.
Other suggestions the water board has put forward to the city council involve putting contraceptive drugs into food. The council imposed a five-year ban on hunting deer in 2004.
