The scientific research in the GPNP: Invasive Alien Species (IAS)
Exotic (or alien) species are species alien to the local natural flora that become establish themselves in a new territory, brought in voluntarily or accidentally by humans. Some of them are adapted to different ecological conditions, have a great ability to reproduce and cause significant socio-economic and environmental impacts; they are called Invasive Exotic Species. Invasive species are among the main contributors to global biodiversity erosion, as they can spread widely, replace local vegetation and alter habitats and landscapes.
Valle d'Aosta and Piedmont have drawn up lists of invasive species (blacklists) in their respective regions that can create problems for agriculture (reduction in forage quality), public health (allergies and serious skin damage) and biodiversity (competition and replacement by wild species).
In recent years, invasive species have also been observed within the Gran Paradiso Park (on the borders and in the valley bottom). The monitoring of at-risk areas is also done annually with the use of apps, a specific one supplied to the park rangers that allows them to immediately alert, with a notification via Telegram channel, the PNGP Botanical Office to coordinate a prompt intervention.
Citizens and tourists can also report SEIs using the AlienAlp app available on the stores.
In Paradisia exotic species are subject to strict control and monitoring
scientific monitoring and those that show invasive character are contained or eradicated.
