Invasive Species

Non-Native Invasive Species

There are many non-native plant species in Northern Ireland which don’t cause problems. A few, however, can become invasive and upset the balance of the ecosystem. They are often bigger, faster-growing or more aggressive than native species and may take over the habitat where they grow.

The Northern Ireland Government website provides details of invasive species https://www.nidirect.gov.uk/articles/invasive-plants

Invasive aquatic species

Ponds can create a wonderful feature in your garden and are often a haven for wildlife. However, if not cared for properly, some pond plants can take over your pond. Getting rid of some of the worst invasive species can take some time and a number of growing seasons. www.nidirect.gov.uk/articles/invasive-aquatic-plants
