Invasive Species

Invasive plants and animals can have significant, often detrimental impacts on the ecology of our rivers. These plants and animals can outcompete native species which puts our native flora and fauna at risk. Furthermore, the presence or specific behaviours of these plants and animals can have significant impacts on the physical environment, which can influence habitat suitability for native fauna and flora.
