Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).

FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Features
Medium sized tree up to 25 m high with straight trunk, and spreading or slightly drooping branches. The very thick purplish brown bark is deeply fissured into scaly plates. Needles are held in pairs, and are up to 15 cm long arranged in untidy whorls. Two strains in NZ can be identified from needle colour: the ”blue” strain, with grey-green to blue-green needles: the ”green” strain with yellow-green needles. Male and female cones arise in separate clusters on young shoots. The mature female cones are up to 8 cm long, covered in many stout, sharp spines, and are arranged in whorls around the branches.
Similar taxa
Long needles in pairs and the persistent, large, very prickly cones of Pinus muricata are distinctive.
