This report presents new data on growth of high value tropical timber species in southeastern and north Queensland, and discusses best-bet configurations for mixed-species plantations. The project measured key trial sites in southeastern and north Queensland, and used this and previous data to analyse species by site productivity, and mixed-species designs. The project presented these results and recommendations via a range of extension activities – the report summarises a series of workshops attended by growers, extension staff and researchers in north, central and southeastern Queensland and northern New South Wales.
