Paragraph 2 Isolation:

F1The appropriate authority shall be satisfied that stands are situated at a reasonable distance from poor stands of the same species, or from stands of a related species or variety which can form hybrids with the species in respect of which application is made, so as to reduce the chances of the stand’s quality and characteristics being detrimentally affected by such poor stands. The appropriate authority shall pay particular attention to this requirement when the stands surrounding autochthonous or indigenous stands are not autochthonous or indigenous or if they are of unknown origin.
