On 26 June 2024, it is exactly 70 years since the founding of the IOO, the predecessor of the Netherlands Institute of Ecology (NIOO-KNAW). Below is a growing overview of activities in the lustrum year.

On 26 June we will celebrate the end of NIOO's Lustrum year of 70 years of ecology. And a new year to come. We will do this together with NIOO staff, students and alumni. More information about the programme will follow soon.

Every year around World Animal Day, we go on safari in our own gardens looking for the important but often overlooked soil animals. This year marks the 11th edition of the Soil Animal Days. The annual event organised by a growing number of partners, is now welcoming observations all year round and including from countries outside the Netherlands!
