There has been much talk about old-growth forests, primal
forests, autopotetic forests etc. Some of these discussions are
presented or summarized on the ENTS website: http://www.nativetreesociety.org/oldgrowth/index_oldgrowth.htm
In practical terms we commonly think of old-growth forests as
forests containing a fair percentage of mature trees that has
been little impacted by human activities. These may be giant
trees of the Redwoods National Park or miniature trees from atop
a wind swept mountain. There are some characterisitics of
typical old-growth. A nice summary of many of these
characterisitics are presented in a 506 kb PDF file from the
Ontario Extension Notes:
"THE OLD-GROWTH FORESTS OF SOUTHERN ONTARIO"
"This Extension Note provides information on the
characteristics of old-growth forests and the many species that
depend on these features for survival."
The article not only deals with the structure of old-growth
forest, but natural disturbances, ecosystems, wildlife,
diversity, succession and includes some excellent illustrations.
I would encourage people to download and read this document.
