Ian Brown is a blackwood grower and co-author of Blackwood A handbook for Growers and End Users, the New Zealand bible on all things blackwood.
He has recently written a fine update on blackwood research including some new findings about clonal blackwood. It is available on Ian’s blog on the New Zealand Farm Forestry Association website (link below):
