Living close to nature for many people involves some integration
with forests.  Often this is little more than being an informed
voter, but for me it is my backyard.  This partnership results in a
lot of curiosity and that led me to a book which could be
important.

  The Hidden Forest
  by: Jon R. Luoma
  published 1999

I smugly started reading this book expecting to find
a biased viewpoint and little new information.  What
if found was a good history of ecology and enough
new information to change my view of forests.  I highly
recommend this book to anyone interested in forest ecology.

There are too many good quotes, so i'll list some of the
facts presented:

* The Andrews forest in Oregon is probably the most studied
  forest in the world.  The original goals were economic, but
  because of some surprises they now are concentrating on
  pure ecology.  They are trying to understand how a forest works.

* Nitrogen fixing occurs in the canopy by the lichen Lobaria.

* The conifer needles contain a fungi that produce toxins
  when insects attack.

* Thousands of new soil animals were discovered and most
  have not been cataloged yet.

* The ratio of root effectiveness to fungi is about a thousand
  to one.  In other words, the nutriments are gathered by the
  fungi and presented to the roots.

* A thimble full of soil can have a mile of fungi threads.
  and a hundred million bacteria.

* A relationship was found between one rootlet and a single
  leaf.  They work in pairs.  This was measured but no one
  can explain it yet, they exchange nutriments.

* About 40 percent of a leaf's output goes to support the fungi
  needed by the tree.

* Forests in Japan and Europe are in decline and may be dying.
  The Andrews data suggests that old trees use different fungi
  than new trees and if you cut all the old ones the fungi is
  lost.  Also, cutting a block of trees prevents the lichen
  from spreading and it dies.  In other words, we may have killed
  most old growth style forests, and we don't know what we
  are doing with the new forests.
