Influence of cyclonic winds on the performance of hardwood plantations in tropical north Queensland.

Abstract

Severe Tropical Cyclone Yasi crossed the far north Queensland coast at Mission Beach on February 3rd, 2011, shattering the regions developing hardwood plantation industry. The cyclone’s path covered the primary areas of hardwood and softwood plantations in this region, causing widespread destruction. The extent of cyclone damage, coupled with the weak international economy has resulted in a severe decline in industry confidence for the future of timber plantations in this region.

This report reviews the impacts of Severe TC Yasi on the performance of key hardwood plantation species in north Queensland. It summarises the influence of species, genetics, plantation design, management and age on plantation resilience. The information will contribute to a “Best Practice Guide for Timber Plantations in Cyclonic Areas” to be produced by Timber Queensland. This will assist companies with future plantation investment decisions in the tropical cyclone zone. 2 200 trees were assessed, including 44 species at 32 localities located from Daintree to Townsville. Data are also presented for a post-cyclone assessment of 5 900 African mahogany trees on four sites in the Ingham region.
