Abstract
Abstract. The introduction of alien plant species can lead to biological
invasions, which have major impacts on people and the environment.
Trachycarpus fortunei (Hook.) H. Wendl. (Arecaceae) is an alien plant (palm tree) that has been
introduced as an ornamental into urban areas across the world, but in many
regions, it has started invading forests and other natural environments
leading to negative impacts. To improve understanding and guide management,
this study sought to assess people's knowledge and perceptions of T. fortunei in
Ticino, the region in Switzerland where invasions of the species are most
common. To achieve this goal, an online survey was conducted, and a total of
487 responses were received. The formal name(s) (scientific or common names)
of T. fortunei were unknown to almost all participants (89 %), and people mostly
just called them “palm”. Most respondents were familiar with the term
invasive alien species (IAS) (88 %) and were aware of the invasiveness
(spread) of T. fortunei (73 %). The study showed that although people like to see the
palm in the region (51 %) and enjoyed the related sense of place it
provides, respondents have become aware of the challenges associated with
invasions and the majority (65 %) would like to see more done to control
the spread of T. fortunei invasions within natural areas, particularly forests. To
improve management, a large number of respondents (63 %) mentioned that
education and awareness programmes should be implemented to provide people
with knowledge on how to deal with invasive alien plants and thus prevent
further spread. Almost a third of respondents supported (32 %) the
regulated sale of T. fortunei in an effort to reduce invasions. Educational level,
gender, and age affected response patterns, and this needs to be accounted
for within strategic management planning, in particular, within education and
awareness-raising initiatives. Tailored and targeted educational campaigns
and management plans need to be established to prioritise and improve
control of this invasive palm in Switzerland in the long term.
