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.=20

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 (Fukuoka en masse!) There are three large contour earth banks
in the plantation that act as swales in effect. The resulting growth of
trees immediately above and below these banks is remarkable -
particularly with the Acacia's. Surprisingly the other species of the
planting have not responded as well as the acacia's to this situation.
We will have our first seed harvest this year as well which we will be
using in other plantings on this and other farms next year.=20

Again if anyone else has any silvicultural tales - particularly with
wattles please drop a line or two. I=92ve put photos up on our web site =
of
the this recent sojourn into the triffids =96

Hello People, 
 
Following is a copy of a letter I recently sent to the <a
href=3D"http://www.permaculture.org.au/">http://www.permaculture.org.au</=
a> forum
that may be of interest to permaculture people who grow acacia=92s for
forestry and other purposes =96 especially Acacia mearnsii (late black
wattle =96 the black wattle used by Masanobu Fukuoka) and its close
relative Acacia dealbata (silver wattle). =
<o:p></o:p>

<p class=3DMsoNormal><font size=3D1 color=3Dblack face=3DArial><span =
style=3D'font-size:
9.0pt;font-family:Arial;color:black'><o:p>&nbsp;</o:p></span></font></p>

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 =
<st1:country-region><st1:place>Wales</st1:place></st=
1:country-region> provenance) at a client's =
<st1:place><st1:PlaceName>Otways</st1:PlaceName> =
<st1:PlaceType>Ranges</st1:PlaceType></st1:place> property (South Eastern Australia =96 very poor tertiary
gravels @&lt; 550mm rainfall). I used a Husqvarna
pole saw and associated pruning paraphenalia =
to do
the job =96 it was great for the neck!! <o:p></o:p>

<p class=3DMsoNormal><font size=3D1 color=3Dblack face=3DArial><span =
style=3D'font-size:
9.0pt;font-family:Arial;color:black'><o:p>&nbsp;</o:p></span></font></p>

I wondered if anyone had any =
experiences
with these species or similar in temperate conditions. =
<o:p></o:p>

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&nbsp;at breast =
height (DOB
=3D 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. =
