I looked at it. The 'was' and 'is'. Your claim that the is has 17 times as
many trees does not pass the giggle test. In fact, this timber propaganda
site doesn't seem to have any facts at all, just opinions promoting the new
'fire sale' of timber right. I'm disappointed. I would have expected this

And it is low intensity fires that clear the understory and small diameter
trees, as is being pursued in the rest of the forest ( without the virgin
timber). One factor not noted is that local rainfall has a serious role in
detemrining the intensity of fires. Drought condtions can lead to even old

Supporting documentation? I've looked at
Table nine suggests 5.4*7500 = 40,500 trees > 24" dbh, not 120,000. However,
this is the east rim,not the 'virgin' north.
Note: I am not a hardass here. I play the rebutter in posts from Larry
because he is so obviously promoting timber sales, not forest management,
and never supports a word he says.

That was never mentioned. Why? Is it the fact that dwarf mistletoe is
normally kept in check by the periodic low intensity brush fires that are
"Less intense fire can beneficially reduce dwarf mistletoe by scorching
infected areas of the lower crown and is most likely the primary limiting
factor of this parasitic plant in a naturally functioning system."

No logging roads? Pity..

Virgin timber! No wonder they want in..

"The normal fire return interval in ponderosa pine is 2-10 years, but
research indicates optimum fuel loading for a low intensity burn is probably
closer to 4 years.
This has been much more credible than Larry's rants, but you haven't given
much of any facts or references to prove your points. The mistletoe should
be suppressed by fire and I cannot believe that all these large diameter
trees are infected.
The question really revolves around:
Can environmental protection and preservation of natural ecosystems co-exist
with a capitalism ( exploitation ) driven economy? The evidence that the
bias is towards exploitation here is rather strong. The fire suppression
that created the problem was driven by the timber industry and the current
drive to 'reduce fuel loads' is driven by the timber industry and..
You really need to protect the national forests from the pressure to
exploit. It is just too easy to make up a 'rationale' rather than a reason
and use it to justify anything.
