In order to be able to observe and monitor wild bird populations, “ringing” is used as a tool. This makes it possible to study migration and demographics. Bird Ringing Centers are hosted in scientific institutions and in Belgium, the center goes under the name BeBirds and is embedded in the Royal Belgian Institute of Natural Sciences.
As a citizen you can become a bird ringer and if you find a ringed bird, you are kindly asked to let the BeBirds know.
More information is available on the BeBirds website 
.
FlatwormWatch aims to elucidate which species of non-native terrestrial flatworms are already present in Belgium with the help of citizens. Besides making an inventory of species already observed in Belgium, the project also aims to map the distribution of the species in question, to get an idea of how these species entered our country and to create awareness of the risks of non-native flatworms. These non-native flatworms can have a large impact on biodiversity as they are voracious predators.
As a participant of the project, you will actively look for this hidden species group in different places such as you garden or greenhouse.
More information on the project can be found on the websites of the Royal Belgian Institute of Natural Sciences (in Dutch or French ) and the Belgian National Scientific Secretariat on Invasive Alien Species .
