An interview with Pondweed

caisieWhere do you come from?

pondweedI come from Southern Africa, but I am now invasive to mainland Europe, the UK and Ireland.

caisieHow did you get here?

Who are CAISIE?

As every day passes by Invasive alien species are running, swimming or lingering around under our noses, going undetected, blending into the background and slowly creating chaos for our native species.

CAISIE stands for The Control of Aquatic Invasive Species and Restoration of Natural Communities in Ireland. The CAISIE team is made up of a Senior Scientist, Project Manager, 2 Research Officers and a Research Assistant.

This 4 year EU funded project commenced in September 2009. The broad objective of the project is to contribute to the halting of biodiversity loss in Ireland by preventing further impacts on native biodiversity from high impact aquatic invasive species. The team will develop and demonstrate effective control methods, and also aim raise levels of awareness throughout the country.
