Hydrocharis laevigata in Europe

Area of Science:

• Botany
• Ecology
• Invasive Species Biology

Background:

• Hydrocharis laevigata is a South American floating-leaf aquatic plant.
• It is recognized as an invasive species globally.
• Recent findings indicate its naturalization in European water bodies.

Purpose of the Study:

• To document the current distribution of Hydrocharis laevigata in Europe.
• To provide insights into the taxonomy, biology, and habitat of the invasive species.
• To highlight the negative impacts of Hydrocharis laevigata on European ecosystems.

Main Methods:

• Literature review of published records and observations.
• Geographical distribution mapping within Europe.
• Synthesis of biological and ecological data.

Main Results:

• Naturalized populations of Hydrocharis laevigata are confirmed in the Iberian Peninsula, Hungary, Poland, Sweden, Belgium, and the Netherlands.
• The species demonstrates high adaptability to various European aquatic environments.
• Factors contributing to its spread include ornamental use, eutrophication, and climate change.

Conclusions:

• Hydrocharis laevigata poses a significant threat to European aquatic ecosystems and biodiversity.
• Early detection and management are crucial to mitigate its invasive impacts.
• Further research on control strategies and long-term ecological effects is recommended.
