Invasive species

Invasive species of plants are plants that migrated outside their natural habitat and they can cause major disruption to ecosystems by interfering with local species. They are one of the major causes of worldwide biodiversity decline, particularly due to their high ability to spread and invade environments (proliferation via seeds or roots). Japanese knotweed, butterfly bush, mugwort, etc. are invasive species that do not thrive in wetlands. The main invasive species in the wetlands is the Giant Goldenrod. Asters-CEN74 has been carrying out advisory work, maintenance and a management plan for the commune of Praz-sur-Arly and the SMBVA (Syndicat mixte du bassin versant de l'Arly) since 2016.
