In Dave's defense, there is a major point here.  NSR lands (Not sufficiently
restocked) are a growing problem.  In B.C., it is particularly true because
of stiff public resistance to herbicide use.  Although NSR lands may
eventually regenerate to their former state, the delay forces us to expand
operations.  Clearcuts and fires are vastly different in terms of the
types of weeds they encourage- regeneration is not the same.  I cite as an
example the system I am working with in the Boreal.  Fires encourage the
development of fireweed, which does not really outcompete spruce in NE B.C. 
However, Calamagrostis is the plant that comes in after clearcutting- this
grass can delay spruce development for up to a decade, allowing poplar to
get there first.  Where fires are few, I personally question the sanity of
clearcutting at all.  I don't have recent data, but in 1989 NSR land in B.C.
included 1.1 million ha in high priority forest lands, despite planting
200,000,000 seedlings per year.  This mandates 87,000 ha of treatment per
year just to sustain things, at costs which are now up to ca. $700/ha. on
difficult sites. (Most of these figures are from the B.C. Ministry of 
forests).  -RSW
