22 mei

In en rond het museum zijn er op 22 mei diverse activiteiten. Doe bijvoorbeeld voor onze deur mee aan een 'bioblitz'. Daarbij ga je buiten aan de slag met de vraag: wat leeft er op 100 vierkante meter? Ontdek samen hoeveel soorten er te vinden zijn. Wie weet wat we allemaal tegenkomen, misschien wel een nieuwe soort!

Toren van al het leven

Zonder bloemen geen bijen, zonder plankton geen vis, en zonder bomen geen apen. Al het leven is afhankelijk van ander leven. Biodiversiteit heet dat. Maar als er te veel soorten verdwijnen, staat het evenwicht op het spel… Houd jij de Toren van al het

our manifesto

A liveable world is a matter of choice

The climate and biodiversity crisis rages on, so far however, the youngsters have hardly been heard and that is what we worry about. With the manifesto 'Time for biodiversity' (only in Dutch) we want to draw attention from politicians to the liveability of our world and the future of all the following generations.

Biodiversiteit & wij

We leven in het tijdperk van de mens. Onze populatie is ontploft. Jij en 8 miljard medemensen vragen veel van de aarde en het leven daarop. In de nieuwe museumtour ontdek je hoe kwetsbaar biodiversiteit is en ook hoe veerkrachtig. De interactieve tour is vanaf 22 mei te vinden in de Naturalis museumapp genaamd 'Biodiversiteit & wij'.

wijs in de wijk

Weet jij een ander woord voor biodiversiteit? En waar ben je het liefst: in de stad of in de natuur? Babbel onder het genot van een ijsje over biodiversiteit met de 'twijfel-schappers'. Op Wereldbiodiversiteitsdag rijdt de Wijsco-kar door de Leidse wijken, onder meer langs het Plantsoen voor de actitiveiten van City of Science 2022. Hou je oren dus open voor het geluid van de (w)ijscokar!

There's a lot we can achieve if we all pitch in together. Here are five tips for things to do at home.

Help promote biodiversity

Be amazed: Take a good look at the wonders all around you. The more you know about nature, the more you will learn to appreciate it. So get out there, and discover the different kinds of life that can be found everywhere!
Bring a bag: Take your own bag to the supermarket, and be sure to throw any old, worn-out plastic bags into the recycling bin. Littered bags can end up in the ocean, where tiny animals gobble up tiny pieces of plastic. Eventually they end up inside fish.
Meat-free Mondays: Most animals bred for consumption are fed on soy products. To meet the growing need for soy, many tropical regions are being destroyed – magnificent forests that are essential for biodiversity.
Plant flowers: Plant some lavender or marjoram in your garden or on your balcony, and watch the biodiversity thrive! The flowers on these herbs will attract many different species of butterfly and other insects.
Insect hotels: They are becoming increasingly popular in cities: hotels for insects, where species such as ladybugs or butterflies can safely spend the winter. If you have the space, why not put one in your own garden?

Like you and I, bees differ in the food they eat. It is important that there is sufficient and diverse food in the form of nectar and pollen for different bees. You can help with this by making a flowering arch: a composition of different wild plants, with different flowering periods throughout the year, to provide the different bee species with food. You can use the bloom arches app for this.
