Safeguarding Malta’s Ecosystems: Understanding And Combating Invasive Alien Species
In a world where environmental concerns are increasingly prominent, it’s crucial to understand the impact of Invasive Alien Species (IAS) on our ecosystems. As the national regulator on the environment, ERA (Environmental & Resources Authority) is committed to promoting sound environmental management practices and safeguarding Malta’s delicate ecosystem.

1. Understanding Invasive Alien Species (IAS)
IAS refer to animals, plants, fungi, and organisms introduced into an environment outside their natural range. Whether intentional or accidental, these species can pose significant threats to native wildlife and human health.
They become invasive when they thrive outside their natural range, posing risks to local biodiversity, human health, and the economy. This includes environmental harm such as predation, competition for resources with native species, spread of diseases, hybridisation with native species, alteration of landscapes and habitats, and reduction of ecosystem services.
2. How do they spread?
Globalisation and improved transport have boosted the spread of invasive alien species. Introductions can happen accidentally or on purpose. For example, shipping vessels unintentionally carry organisms in their ballast water, which is discharged at ports, introducing these species to new environments.
3. IAS in Malta: Identifying the Threats
In Malta, several invasive species have established themselves, including Golden Wreath Wattle, Tree-of-heaven, Balloon Vine, Crimson Fountaingrass, and Crayfish. Despite their innocuous appearance, these species can outcompete native flora and fauna, leading to ecosystem imbalance.
4. Taking Action: Reporting and Prevention
Recognising and reporting sightings of invasive species are crucial steps in combating their spread. ERA encourages proactive engagement from the public through ERA reporting. Additionally, promoting awareness and understanding of IAS helps prevent their unintentional introduction.
5. Promoting Indigenous Alternatives
As part of their commitment to environmental sustainability, ERA advocates for the use of indigenous plant species in landscaping and gardening. By choosing native flora, individuals contribute to preserving Malta’s unique biodiversity and ecosystem integrity.
Combating Invasive Alien Species requires collective effort and proactive engagement from all sectors of society. By working together and choosing sustainable practices, we can ensure a vibrant and healthy ecosystem for generations to come.
