Hello People, I have just spent the last couple of weeks
form and lift (clearwood) pruning about 7000-8000 5 year
old Acacia dealbata (Snug Tasmania provenance) and mearnsii's (Bodalla New South I wondered if anyone had any experiences
with these species or similar in temperate conditions. The next stage is thinning as competition
effects are the next issue to deal with. These remarkable species are interrow planted on a keyline layout with Corymbia
maculata, Eucalyptus cladocalyx and Euc. camaldulensis.
and range in heights from 6-12 metres with diameters at breast height (DOB
= officially 1300mm - unofficially varies between humans!) between 75-250mm.
Higher density stands of 2m spacing between trees generate more early thinnings as competition effects come earlier. >From a 1000
tree stand at this spacing we got about 2 m3 of thinnings
suitable for firewood. The rest of the trees are at 3m spacings
and yielded significantly less. If you are considering growing a woodlot with
firewood as a residual product of silviculture this is
worth taking notice of. All of the trees are planted on Yeomans
plow ripped and mounded ground preparation (on a keyline layout) with no chemical weed control used ever.
In response native species have colonised the site in
abundance, with the planted trees forming only a small proportion of the total
species on site. I devised years ago to only mulch mow every second row leaving
the spare row for the native regrowth and as a site for the deposition of prunings. The yield of this material from the last pruning
session was considerable and is sure to encourage a range of ecological
processes ( Cheers, Yours and Growing, Darren J. Doherty Applied Diploma of
