Qld Maple was planted at gadgarra state forest(nth qld),in the 1930's,in almost pure stands(some exotics/natives were planted in and around them).Very little thinning/or silvicultural work was done to these plantations,hence growth rates were rather poor.In areas where underplantings were performed,the trees(maple) grew much better.Photo is a good idea of average size attained.:2tsup:
