Summary
[edit]DescriptionAche nodiflore (Helosciadium nodiflorum) et algues filamenteuses dans les Baillons aout 2017a 01.jpg |
Français : Ache nodiflore (Helosciadium nodiflorum), l'une des plantes dominantes des herbiers subaquatiques des Baillons à Enquin-sur-Baillons (ici en aout 2017). L'état écologique de ces herbiers est remarquable, mais on observe néanmoins ici et là des touffes d'algues filamenteuses (qui pourraient indiquer une une légère pollution organique). La flore de cette partie du cours d'eau est particulièrement riche et bien développée, et elle abrite de nombreux invertébrés aquatiques. Mais peu de poissons (quelques truites) et escargots étaient visibles lors de mes visites. Rem : L'eau est restée cristalline malgré des pluies récurrentes durant 15 jours.
English: Ache nodiflore (Helosciadium nodiflorum), one of the dominant plants of rich "the Baillons River"'s subaqueous herbariums at Enquin-sur-Baillons (northern France, here in August 2017). Nevertheless, here and there tufts of filamentous algae (which could result from a slight organic pollution) are observed. The flora of this stream part is particularly rich and well developed, and it is home to many aquatic invertebrates. But few fish (a few trout) and snails were visible during my visits. Rem: The water remained crystalline despite recurrent rains for 15 days. |
