By taking part in Biodiversity Week, you help scientists, nature organisations, and governments better understand biodiversity in Belgium. Every observation helps build a clearer picture of where species are thriving and where nature needs extra care.
And there is more: participating is not only useful, it is also fun. You discover nature in a different way. Suddenly, you notice butterflies, wildflowers, mushrooms, birds, and insects you may have walked past countless times before.
Together, we can make biodiversity visible — and show how much life still surrounds us when we take the time to look closely.
So: put on your walking shoes, open the app, and become a biodiversity explorer yourself. Every species counts. Every observation matters.
