There is a lot of valuable nature at Tata Steel’s site in IJmuiden.
The biotopes at the steel company include wet dune valleys, herb-rich grasslands and forest which is more than 100 years old.
Special species living there include the sand lizard, natterjack toad, nightingale, the grasshopper warbler, the argus butterfly and rare orchids such as dogwort and swamp wasporchis.
There is even a moss species which does not occur anywhere else in the Netherlands: the lime purple stiltskin.
The site, in particular the lagoons, are situated on former intertidal land at the head of the River Dee Estuary.
The lagoons provide habitat for a number of breeding bird species.
A watch-tower and a bird hide allows Tata Steel to work with local schools.
Tata Steel provides ongoing assistance with the maintenance of the islands and reedbeds. This involves suppressing vegetation, as terns prefer to nest on bare, stony ground.
