An incurable illness

The 42 000 plane trees bordering the canal du Midi face extinction in the near future … The canker stain of the plane tree is a microscopic fungus which settles and develops inside the tree
and blocks its sap channels. Tt can kill a plane tree in only 6 months to 5 years.

The disease spreads by contact: either via water and roots (very intertwined), or because of the friction of boats and bikes against the network of plane tree roots when they are moored outside the authorized sites or directly alongside the trees.

It spreads rapidly and, even worse, cannot be stopped. After extensive research, INRA (National Institute of Agronomic Research) concluded that the disease could not be fought chemically or biologically. If the test protocols for preserving healthy trees continue as they are, there is currently only one solution : to cut down and burn the affected trees.

Despite these preventive efforts, around 20 500 trees were felled since 2006.

This situation is now so urgent that we must all mobilise!


By donating today, you can also do your bit to help this rescue plan get off the ground.  

Thanks to you, 8 100 trees have already been replanted since the launch of the program !
