× Likelihood For "Pest is Introduced" the lowest value of Entry or Establishment, as both are required for a successful introduction. For "Pest Spreads to Maximum Extent" this is an expert judgement on the likelihood of this occurrence. See Guidance Document for more Information Close Likelihood [1 - 5]			3
× Spread The rate at which a pest can expand, by natural dispersal only, within an area. See Guidance Document for more Information Close Spread [1 - 5]				4
× Impact The highest value from economic, environmental or social impacts. See Guidance Document for more Information Close Impact [1 - 5]		2
× Value at Risk The value of the hosts or industries at risk from this pest in the UK. See Guidance Document for more Information Close Value at Risk [1 - 5]					5
× Likelihood x Impact The likelihood multiplied by the impact, which shows the risk to the sector. See Guidance Document for more Information Close Likelihood x Impact [1 - 25]	6

Action

Statutory action against interceptions and outbreaks

General Comments

Fungal pathogen of spruce and certain rhododendron (Labrador tea) species. Limited risk of introduction, but a PRA could help resolve whether future inclusion in legislation would be appropriate.
