Arnhem is a city that lies partially in the Veluwe, a nature park in the east of the Netherlands.

The zoo is popular with both Dutch and German people, and receives about 1 million visitors annually.

They use an artificial moon to stimulate sexual reproduction of corals in their reef, and also clone some 60 varieties.

The Socorro dove (Zenaida graysoni) for example does not exist outside captivity at present; it was wiped out by introduced mammals on its home island.

The species is being bred in Burgers' Zoo for eventual reintroduction into the wild.
