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.
Waders wane while geese gain
A major new study led by BTO, working with the Wetland Bird Survey (WeBS) partners, JNCC, RSPB and in association with WWT, provides detailed information on the importance of Great Britain for waterbirds each winter.
How birdwatchers can tell us about declining mammals
The UK’s mammals present particular challenges for monitoring; they live in a wide variety of habitats, vary enormously in size and can be very difficult to see, but as this paper shows, Britain’s army of volunteer bird surveyors could come to the rescue.

The Breeding Bird Survey is the main scheme for monitoring the population changes of the UK’s common and widespread breeding birds.
