Essential even. Gump fires and prairie (savannah) fires too. Clears up
the dead stuff, makes way for new growth.

There are many different types of forest in the world. Some have
species of plants that have evolved to survive, and even depend on,
periodic fires.
For other forest types fire is very destructive and they can take
centuries to recover. If the destruction covers a large enough area
some will never recover.

I suspect you are personaly familiar with the former. Don't make the
mistake of therefore assuming that fire is essential everywhere.

Of the dozen or so types that i have looked at that are common in the US and
Canada all require semi-periodic fires; usually in the 10 to 20 years
range. High chapparal requires fires about every 3 to 5 years to prosper.
I do not claim to know the properties of all forests, and specifically rain
forests i expect to be different.

I don't think "rain forests" have fires. Anyone ever remember a fire
along the Amazon?

There are rain forests in far different climates than the Amazon basin, some
quite cool/cold (includes snow). I'll bet that some of those prosper best
with semi-periodic burns also.

Hmmm. The hint is in the name. One of the defining characteristics of
a rain forest (tropical and temperate) is the occurence of copious and
frequent rain.
You may care to elaborate on how natural selection would favour an
ecosystem of plants that need fire to prosper, in an environment that
is very very wet?
Alternatively, if you believe in intelligent design, you could explain
why god would waste so many matches trying to start a fire there!

Richard, Didn't you say you are in Poway? Do you know a fellow named
