Justification | EOO 25 km², AOO 1 km², this species occurs on cliffs amidst extensive pine plantations. Although the habitat is unsuitable for the establishment of pine plantations and therefore it is unlikely to have lost much habitat, cliffs are prone to invasion by escaping pine seedlings from surrounding plantations which may potentially threaten the two known existing locations. |
