Partly on the occasion of the 20th anniversary of NLadviseurs, on 11 September 2025, all people and organisations who work every day for our precious nature will be put in the spotlight. Our world desperately needs nature heroes. Do you work in the green sector, do you have a heart that beats for a healthy and green world? Then secure a spot at this knowledge event.

This is a chance to further develop your green knowledge and be inspired by the best stories and projects about our nature, valuable and in-depth keynotes, excursions and interactive workshops.

The ticket gives access to the Open Air Museum for the whole day, so you can spend the morning in the park beforehand. The day will end with drinks and the Nature Heroes Award ceremony.
