There is an invasive water plant here called jussie. It establishes itself in the still, quiet sections of the rivers and fills up the étangs. In order to control it, it is necessary to carefully pull it out. Strimming it simply causes it to spread, when fragments take root after floating downstream. One of the local river technician's major tasks is co-ordinating the war on jussie. Recently he has put an information board up by the bridge in Preuilly.
