Bob Zybach:  Depending on what you mean by "...There are now far more trees spread over many thousands more acres in western Oregon than at any time in history.", e.g.:  1.  The assertion's year certain baseline basis, 2.  The number of trees in that year, 3.  The number of trees now etc., this is, at best, an extraordinarily sketchy statement.  Finally, are there url based data that prove this?
