- If forests do not support our society, then presumably we could do OK
- without them? Personally, I don't think so. Our society derives much more
- from forests than wood fiber. I never thought I'd be arguing the point with
- someone as environmentally aware as yourself.

- I guess I see a difference between disappearing, and decreasing. You're
- right, though, total forest acreage in the United States has decreased since
- 1952 by about 5%. One projection is that it will decrease by another 4% by
- the year 2040. But during the period of 1952 to 1987, forest acreage
- actually peaked in the early '60s. This suggests that there is an ebb and
- flow of total land area under forest cover at any time. I would like to
- point out that the projection is a net decrease of 4%, and forest acreage
- may well peak again in the future (my source dows not give this
- information). With this in mind, a projection to a different year, say
- 2020, may indicate a net increase (no data for this, I'm just interpreting
- the report that I have cautiously).
-
- A second point about all of this is that of the total forest land in the US
- (as of 1987) about two thirds was timberland, and a third was not in timber
- production. The percent of timber-producing forest is somewhat less today
- since more and more forest land is taken out of timber production by
- congress. So there is a good portion of US forests (Nationl forests,
- specifically) that will never be cut, therefore the forests are not
- disappearing. Forest preserves are good to a point. We need to maintain
- some of our forests in a relatively natural state for a whole host of
- reasons - this is to the credit of some of the more moderate environmental
- groups (e.g. The Nature Conservancy) as well as the USFS, the BLM and the
- SCS, in additon to the numerous state agencies.
-
- The statistics cited above is from a peer reviewed article "Changes in
- Private Timberland" by R. J. Alig and D. N. Wear in the May,1992 Journal
- of Forestry.
-
- If you look this article up, I suggest you also read "The Reforestation
- Challenge" if you have any misconceptions about what timber companies do for
- forests.
