Let’s work together against invasive exotic plants!

Ludwigia grandiflora

   

What you shouldn’t do:

- introduce exotic plants into the natural environment, particularly those that are known to be invasive
- propagate these species deliberately (by growing them from garden to garden) or inadvertently (by throwing away the contents of an aquarium or plant debris into the natural environment, carelessly cleaning out and emptying infested ponds etc.)
- damage environments by creating backfill, drainage, destruction of riverbank woodland, excessive fertilization, …, as this favours colonization by these species
- use herbicides that may pollute water and the water table and cause the opposite to the desired effect by encouraging invasive exotic plants, which are often more resistant than indigenous plants.


What you should do:

- take a responsible attitude when choosing plants for your garden, asking for information about their potentially invasive nature at the time of purchase and taking care to contain their development once you have planted them
- put aquarium plants no longer required in the bin and make sure that water poured down the sink doesn’t contain plant debris
- inform local authorities and/or nature protection organizations (associations, public establishments, authority), if you note the presence of these species near your home
- make sure you are well-informed before embarking on your own uprooting initiative.
