Paragraph 16
When carrying out a survey of susceptible plants and residual material in a demarcated area, the survey must—
(a)
include the inspection, sampling and testing of those plants and that material for the presence of the plant pest;
(b)
focus in particular on susceptible plants which are dead, in poor health or affected by fire or storm; and
(c)
be carried out at an appropriate rate which ensures that the intensity of the survey in the area lying within a radius of 3000 m of an infested susceptible plant is at least four times higher than in the rest of the buffer zone outside that area.
