Solanum elaeagnifolium in Portugal
Solanum elaeagnifolium (Solanaceae: EPPO A2 List) is a herbaceous perennial or a small
shrub, native to the Americas and an alien invasive plant in parts of Asia, Africa and the
EPPO region. Field surveys conducted in December 2021 in two regions in Portugal revealed
the occurrence of this invasive plant species. The first population of S. elaeagnifolium was
found at Costa da Caparica, municipality of Almada (Lisbon region), in an abandoned area
located in an urban environment and next to the ocean and consisted of approximately 200
stems. The second population was found in an abandoned field located in an agricultural area
at Cano, municipality of Sousel (Northern Alentejo region). This infestation was large (>0.5 ha)
and may serve as a reservoir for future invasions in nearby arable fields and olive groves.
Each plant can produce 40-60 fruits with each fruit containing 60-120 seeds which are spread
both naturally (via wind and through water movement) and through human assisted spread
(dispersal via agricultural machinery). Negative impacts include outcompeting native species,
reducing crop yields in agricultural systems and impacts on ecosystem services (for example
pollinators). For both populations, eradication attempts should be applied to eliminate the
invasive alien plant before further spread. Monitoring actions and control of the population
are the measures to prevent further dispersal of the plant in agricultural land in the Cano
site.
