The production and potential of special purpose timber species (Macrocarpa, Paulownia and Regnans), in Southland as an alternative to radiata: A dissertation submitted in partial fulfilment of Diploma in Farm Management in the University of Lincoln

Abstract

A survey was circulated to eighteen mills throughout New Zealand currently involved in milling special purpose timber species. The survey was used to evaluate the quality, efficiency and attitudes of millers towards milling Macrocarpa, Paulownia and Regnans as well as establishing what price mills are prepared to pay on a $/m basis. It was also hoped that general timber properties and potential suitability in a range of commercial uses would be attained. Milling of Macrocarpa, Paulownia and Regnans is carried out in New Zealand in small quantities only, with poor availability being the major limiting factor. Macrocarpa and Regnans are of higher quality than that of Radiata and are generally used for furniture, veneer and joinery. Paulownia is seen to have major potential · as a commercial timber species in New Zealand (with only small coastal areas in Southland suitable for planting in Paulownia) provided a sizeable timber resource is established. The results show that Macrocarpa, Regnans and Paulownia have the potential to replace native species. Significant profits (above those received for Radiata) can be attained from Regnans and Paulownia with Macrocarpa plantations returning profits slightly below that of Radiata.
