The general lower native biodiversity, taxonomic
disharmony and pressure on native ecosystems of islands implies less resilience
to biological invasions. Therefore, it is necessary to consider that species
that are not of major concern in mainland might represent a higher risk on islands.
As a consequence, the collection of data should follow adapted protocols to islands
dimensions and conditions. This would improve the quality and the reliability of
data gathering of invasive species, including citizen science contributions,
complementing research studies.
Some good examples of citizen engagement can
be found in Spain and Portugal. In La
Gomera (Canary Islands), different actions are being taken to remove Pennisetum setaceum involving volunteers
and technicians, and in Menorca (Balearic Islands), more than 25 tons of this species
and Carpobrotus edulis have been removed
from Natura2000 sites this year. In Berlengas Islands (Portugal), native bird
species are nesting after the tackling of invasive species. In Terceira (Azores
Islands), the Azorean Biodiversity Group organize every year citizen science
activities together with students, volunteers and local organizations to
contribute to the Invasoras.pt Citizen Science project.
