Non-native species are regarded as one of the largest threats to biodiversity worldwide. There are more than 3,000 non-native species in the UK. To assess the potential threats of these species, we need the following -
- Reliable information on their presence and numbers
- Knowledge of potential new species to colonise
- A good understanding of the impacts of each species
BTO makes a major contribution to tracking the colonisation of non-natives through its monitoring schemes, and in partnership through the GB Non-Native Species Information Portal (NNSIP). We also undertake research investigating the impacts of non-natives and providing conservation solutions.
