Variable Flatsedge (Cyperus difformis)

Observer

Description

En 2023, j'ai dénombré 8 Cyperus difformis sur ce site, tous regroupés dans une petite zone, les pieds dans l'eau. En 2024, j'ai déraciné 101 plants portant des fruits sur un périmètre élargi, s'étendant non seulement le long de la rive mais aussi en profondeur (vers le centre de l'île). En un an, la population s'est donc multipliée par plus de 10 fois et a gagné du terrain.

En 2023, Cyperus bipartitus était bien présent sur cet emplacement. En 2024, il n'y en a presque plus (mais il y en a ailleurs sur l'île).

Je ne me fais pas d'illusion, il reste encore des têtes. Si je suis en mesure l'an prochain, je ferai un suivi. Au moins, j'aurai fait un effort pour ralentir la propagation.

J'ai fait un signalement sur Sentinelle, mais cet outil est destiné aux espèces exotiques envahissantes. Il semble qu'il n'y a rien de prévu pour la situation présente, i.e. une nouvelle espèce exotique dont on ne connaît pas encore le comportement mais qui ne laisse rien présager de bon...
