In May Mow Down

For the third edition of "En mai, tonte à l'arrêt" ("In May Mow Down"), let a little part of your garden to biodiversity.

During the month of May, Le Vif, in partnership with the non-profit organization Adalia 2.0 and the Biodiversity and Landscape research axis of Gembloux Agro-Bio Tech invite you to leave a plot of your garden alone and observe the life that depends on it.

To participate, nothing could be easier. Just follow these 4 steps:

Step 1: Register

If you don't already have a BioPlanner profile, you can create one starting April 20 by filling out a form at


Step 2 : Grow and observe

From May 1st to 25th

Mark off a no-mow area on your lawn in early May - ideally as large as possible - and let it grow. Log into your BioPlanner profile to record its characteristics and encode the species (flora and fauna) you observe.


Step 3 : Count the flowers on 1 m²

From May 26 to June 2

Randomly mark off one square meter in your no-mowing zone. Go to the "My Control Plot" section in your Bioplanner profile and record the number of flowers for each species present. Record this data by June 3rd.


Step 4 : Results

June 8th

On June 8, you will find the personalized nectar index of your contribution to the operation on your Bioplanner profile, as well as all the results in Le Vif of June 8 and on


By letting this m2 grow, you will have helped pollinators by providing them with more food but you will also have protected your garden because ladybugs, small mammals and other allies will help you get rid of aphids, caterpillars or slugs.
