Risk assessments

Update on templates:


Risk assessment is a key tool in the armoury against invasive non-native species. It is a vital part of any comprehensive prevention strategy


It can be used to aid prioritisation, to help enable effective rapid responses and for underpinning decision-making.  The GB Non-native Species Risk Analysis Mechanism was established in December 2006.  Within this mechanism risk assessments on non-native species are carried out by independent experts and these are reviewed by one peer reviewer and the risk analysis panel of experts (NNRAP).  Following this process risk assessments are available for comment before being finalised.  To find out more about the risk analysis mechanism click here.


Common misconceptions about risk assessments:

To address a number of common misconceptions about non-native species risk assessments, the following points should be noted:

  • Risk assessments consider only the risks posed by a species. They do not consider the practicalities, impacts or other issues relating to the management of the species. They therefore cannot on their own be used to determine what, if any, management response should be undertaken.
  • Risk assessments are advisory and therefore are part of the suite of information on which policy decisions are based.
  • Completed risk assessments are not final and absolute. They are an assessment based on the evidence available at that time. Substantive new scientific evidence may prompt a re-evaluation of the risks and/or a change of policy.


For those undertaking risk assessments:

  • The new NAPRA risk assessment template is available, click here to visit the website from which it can be downloaded.  The website also provides a downloadable user manual with instructions on how to use NAPRA. 
  • For instructions on how to install and use the new software, click here.
  • The risk assessments below also help to provide useful examples on how to complete the assessment process.
  • Risk assessments completed as part of other schemes (e.g. EPPO) may help inform the assessment.


Period for comment

The risk assessments that have completed the process are available from these pages.  They are open for stakeholders to provide comment on the scientific evidence which underpins them for three months from the date of posting on this website (to send in your comments contact us here).

If you would like to be informed when new risk assessments are put online, contact us here and ask to be put onto the risk assessment alert e-list.

Other Risk Assessment Schemes

The European and Meditteranean Plant Protection Organisation (EPPO) carries out pest risk analysis at the European and Meditteranean scale for plant pests and a range of invasive plants.
