<p>The UK is in the process of completing its comprehensive pathway analysis. Rather
than basing this simply on the unintentional pathways of introduction and spread of
species listed as being of Union concern (the minimum required by the Regulation),
the UK has undertaken an extensive assessment of introduction pathways of all established
non-native species in Great Britain and their impacts. This will be used, in addition
to data on species of Union concern and horizon scanning, to support prioritisation.</p><p>
</p><p>Boating and angling have been identified as priorities for Pathway Action Plans
(PAPs) given the recent arrivals of several highly invasive aquatic species, including
killer shrimp and quagga mussel, and are almost complete. In addition to this, a PAP
has been completed for zoos and aquaria and the UK has a long running campaign to
reduce the risk of horticultural escapes (although this is not part of a formal PAP).
Further PAPs will be prioritised based on the results of the comprehensive analysis.</p><p>
</p><p>The Non-Native Species Information Portal (NNSIP) has been established to ensure
a rapid flow of non-native species distribution data into a centralised repository
to facilitate surveillance for new species as well as the spread of established species.
The NNSIP is a partnership that relies on the extensive biological recording networks
present in Great Britain as well as citizen recording. In addition, an alert mechanism
has been established for urgent recording of priority species, which received around
8,000 alerts in 2018. Early detection is particularly critical to support the UK’s
response to the Asian hornet, so a surveillance network of sentinel apiaries is being
used to monitor for the arrival of this species.</p>
