“I have never bought any or planted any, but I have pampas grass in my garden!” Nadine Kersaudy, vice-president of the Communauté de communes du Cap-Sizun (Finistère) sees, like many inhabitants of South Finistère, the proliferation of plants classified as “invasive exotic species”.
“They suffocate the local flora”
“These plants, of which there are about a hundred varieties, are proliferating. Among the best known are the butterfly tree, pampas grass, laurel palm, witch’s claws, trichome garlic… These species are stifling the local flora. Their rapid spread contributes to the decline in biodiversity. They can have an impact on human health.”analyses Philippe Burgevin, responsible for natural spaces, hiking and heritage at the Communauté de communes du Cap-Sizun.
“A threat to the ecosystem”
These species are on sale in many specialist stores. They are found in gardens, agricultural land, along the edges of sidewalks and ditches, but also in areas managed by communities. According to the technician: “They threaten the ecosystem, natural habitats and local species.”
The public authorities are becoming aware of the “invasion”. Thus, the communities of Cap-Sizun, Douarnenez community and Haut Pays Bigouden have joined forces to publish a joint booklet, in order to raise awareness among the population and fight against the proliferation of “invasive exotic species”. This small, fun and accessible booklet can be found in all town halls.
