Hi All,                                Jan 11, 2016
    I just remembered that whole tree harvesting can mean roots as well =
as tops so it may not be a good term to refer to Full tree brown or Full =
tree green. There is enough confusion without piling more on.

Hi Donna & All,                                    Jan 11, 2016
    I will address some of your other comments later but first things =
should come first.

    It would be of great help if this whole tree harvesting were =
documented in a factual way and made public. This, to be credible, =
should be done with care to not exaggerate or wrap in emotion. This =
wears thin quickly.=20

   About 1995 (?) I spent a few hours with a man from Newfoudland who =
had taken Silvaculture in NB and moved directly to BC for work. So I =
asked why he had not remained in Atlantic Canada.  His long reply =
reduced to few words was that Forestry in Atlantic Canada was dead =
by1970; nagged to death by environmentalists plus Forestry here has many =
natural disadvantages: as pulp mills became obsolete they would shut and =
the companies would move on.

  About 8 years ago Irving generated flak by refusing to reroute a road, =
at great cost, to avoid possibly disturbing a Heron colony. A paste from =
one of my e-mails is relevant.   =20
PASTE from my post of Mar 27, 2008 \\\\\\\\\\\\\\\\\\\\\
   In any case those who objected to normal Forestry harvesting cycles=20
of about 100 years will soon look back to those times as the good old=20
days, as more forest land is converted back to farming or to 7-year=20
biomass harvesting cycles.
  END OF PASTE\\\\\\\\\\\\\\\\\ =20
    Shortly after the Cod stocks collapsed many years ago I happened to =
hear an Economics Prof. from Memorial on the radio. According to him, =
Nfld. would do just fine without fisheries; there was Teaching, Highways =
work, Health Care, Police work... all activities which consume wealth =
and no primary industry to create wealth.  This is typical of modern =
'thought'.

    I had wanted as time permitted to discuss the future of Forestry on =
Naturens but unfortunately a brush fire, in the form of whole tree =
harvesting, takes priority. First I think it helps to employ the power =
of self-interest.=20

    There have been shortages of firewood, hardwood for high value =
products and wood pellets in recent years and I would guess that =
biomass, not only for local plants but for export, is a major cause of =
this. If the above washes,after careful documentation, then it should be =
made public.=20

    As I think I observed some time ago, the colossal machine trades =
local jobs for remote jobs and exports wealth. That aspect could also be =
documented to effect I suspect; self-interest again.
