      I have been experimenting with "seedling forests" to study growth
   yield relationships as they pertain to older stands.  For example, I
   planted scots pine seeds at 3 different spacings in the greenhouse, and
   recorded the collar diameter growth of the seedlings over time.  The
   affect of the spacings was expressed nicely in the diameter data.  I
   eventually thinned in each spacing, and could see the response in the
   diameter data.  I'm approaching this as a possible way to "model" what
   goes on in older stands, and/or as a way to verify mathematical models
   of growth and yield.
      Are there any similar experiences out there?  Are you aware of similar
   studies?
                                       Thanks,
