# The Plant Health (EU Exit) Regulations 2019, Paragraph 15


The appropriate UK plant health authority need not demarcate an area in relation to a finding of the plant pest in a relevant UK territory—
(a) where there is evidence that—
(i) the infestation has been caused by the movement of susceptible plants or susceptible wood to the area in which the plant pest was found and that the susceptible plants or susceptible wood were infested with the plant pest before that movement; or
(ii) it is an isolated finding which is not expected to lead to the establishment of the plant pest; and
(b) where it has ascertained from a specific investigation that the plant pest is not established in the area and that it will not successfully breed or spread due to its biology if appropriate eradication measures are taken.
