"Ring wedging occurs when rapid radial growth occurs over several years in certain segments of the tree's circumference, while being extremely slow or absent in others... Examination of complete cross sections can help overcome this problem, and for some species accurate age counts must be based on cross sections rather than increment cores" (3). The species has seen limited use in climate reconstruction (4).EthnobotanyObservationsRemarksSee also Paleobotany of Australia and New Zealand conifers.Citations(1) Farjon 1998.(2) NZ School of Forestry website.
