Non-Native Invasive Species
Along with climate change and habitat loss, non-native invasive species are one of the biggest threats to biodiversity in the Suffolk & Essex Coast & Heaths National Landscape, the rest of the UK and globally.
The direct costs of non-native invasive species have been estimated to be approximately 5% of global GDP* with an estimated cost of £1.8 billion per year to the UK economy**.
Non-native invasive species are causing problems for wildlife and people in the Suffolk & Essex Coast & Heaths National Landscape in the following ways:
- They out-compete native species
- They directly predate on native species
- They bring disease
- They damage habitats and infrastructure
- They cause huge socio-economic costs
There are a number of non-native invasive species that are a cause for concern in the Suffolk & Essex Coast & Heaths National Landscape.
They have been particularly problematic in freshwater, coastal and estuarine habitats. Find out more about the most problematic species.
