What is an invasive alien species?
Also called “invasive”, invasive alien species (IAS) are non-indigenous species, introduced by humans (voluntarily or fortuitously), and whose spontaneous spread can have negative consequences on health, ecosystems (environments natural and native species), agriculture or forestry.
Having a very high capacity for dissemination, these species compete strongly with local species, thus disturbing ecological balances and threatening native flora and fauna. They are recognized as the third cause of the erosion of global biodiversity. In addition, some of these so-called “invasive” species can create real health problems in humans.
As part of the implementation of its 2020-2029 Management Plan, the National Nature Reserve of the Haute Chaîne du Jura is taking action to combat these invasive alien species and invites you to participate on July 22, 2023 from 8:45 a.m. to 12:00 p.m. in the town of Crozet at a participatory site whose objective will be to uproot American solidago stations in order to promote local biodiversity.
Help us promote local biodiversity by pulling out American goldenrods!
Native to North America, these species settle easily in all open environments. Appreciated for the yellow color of their flowers, they were originally introduced as ornamental plants but have since colonized many natural environments to the detriment of the local flora.
