OTOH I've also read about ozone and acid rain slowing production

Subject: [ENTS] Re-Tree Heights- Growth Rates
ENTS, After reading this most lenghtly post . Its hard to follow
when we jump from topic to topic and my memory isn't what it once was.
We talked about this in the past. Did anyone mention the higher C02
levels in the last 100 or so years plays a large factor in these
speedy growth rates along with other factors that have already been
mentioned. I'm finding live oak growth rates to 1/2" radial to 3/4"
thats tremendous. These are live oak stumps 45-50 years old. The mid
growth seems to be the fastest. In older trees the rates are much
slower avg. .125-.25. These rates in live oak have made me re-think
that thousands of years ago the trees would have been even taller.
