Latest update from the BTO: Non-Native Species in Britain
BTO data and expertise have contributed to a major new report on the establishment and spread of non-native species in Britain. Many of our most abundant birds and mammals are included among nearly 2,000 non-native species currently established, and the number of new arrivals has increased dramatically over the last 50 years.
A major new report has found that there has been a dramatic increase over time in the number of non-native species arriving in Britain. Of nearly 2,000 non-native species known to be established in Great Britain, over 600 species have arrived in the six decades since 1950, and 125 since 2000. This list is dominated by higher plants (1,377) with insects as the next most numerous group (278 species). Most of the established non-native species originate from continental Europe but the proportion of new species coming from Asia and North America is increasing.
As a highly visible and relatively well-monitored group, bird species comprise a significant proportion of the database but although well over 300 non-native species are regularly observed in the wild, only 15 are considered established (i.e. with self-sustaining breeding populations). Several species are among the recent arrivals (e.g. Ring-necked Parakeet) and work is continuing to eradicate others (e.g. Ruddy Duck).
Although the majority of non-native species are not considered invasive those that are can cause major ecological or socio-economic impacts if they establish themselves in the wider countryside. Invasive non-native species are considered to be one of the five major threats to biodiversity, estimated to cost the UK economy £1.7 billion every year. Overall about 15% of the species established in Britain are considered to have a negative impact.
The research team looked at how to enhance the ability to detect and report non-native species in Great Britain, creating a new database of nearly 4,000 species within the GB Non-Native Species Information Portal (GB-NNSIP). Data on all of the species can be accessed through the portal’s website at: www.nonnativespecies.org . An integral part of the GB-NNSIP is a rapid-reporting system whereby particularly important new arrivals can be immediately notified to the relevant bodies. One such species, the Asian Hornet, is not yet present in Great Britain but scientists believe could arrive soon, potentially having a serious impact on honey bees and other pollinators on which it preys. Anyone that suspects they have seen this species is encouraged to send in a photograph through the GB-NNSIP’s online recording website ‘Recording Invasive Species Counts’ which can also be used to report sightings of 19 other key species including Water Primrose, American Bullfrog, Carpet Sea-squirt, Tree of heaven, and American skunk-cabbage.

The collation of data for the analysis and review was funded by Defra and coordinated by the NERC Centre for Ecology & Hydrology (CEH) in collaboration with the British Trust for Ornithology (BTO) and the Marine Biological Association (MBA). Additional experts, nominated by the Biological Records Centre volunteer schemes and societies, provided further information on many of the species. Of particular note was the involvement of the Botanical Society of the British Isles (BSBI) who provided information for 1,873 species.
Helen Roy of CEH, who led the team, said “The portal is an excellent example of how collaboration amongst different organisations is vital in addressing potential threats to biodiversity. By sharing information the data compiled give us a comprehensive understanding of non-native species, allowing us to respond rapidly to the arrival of new species. The portal also provides us with a great tool to link with wider European and global initiatives to tackle emerging threats from invasive non-native species.”
Niall Moore from Defra's Non-native Species Secretariat said, “The Non-native Species Information Portal is a key outcome of Government's long-term commitment to tackle the serious problems posed by invasive non-native species. It provides us with the basic information we need on which to base objective and sound policy: we need information on trends to see where to put our effort in future years and we need greater public involvement – provided through RISC. We also need to be alert to new species turning up so we can respond rapidly and hopefully keep them out – the Asian hornet is a good example.”
In relation to bird records, John Marchant of BTO said, “Climate change might easily make Britain more suitable for a wide range of non-native species, like Sacred Ibis, currently thriving in southern Europe. Escapes and breeding of such species might be the beginnings of the next burgeoning new populations. To integrate non-native species recording more completely, we have ensured that all non-natives are fully recordable for BTO surveys.”
