I've been putting together a list of Live Oaks 20' Cir., or
greater here in Ms. While doing so I discovered
a 35 footer in Biloxi,
so I did some research and found 20, 30' or greater Registered
Oaks! Louisiana Live Oak Society has Listings of 5000 registered
I also noticed that some of the Live Oaks I've been measuring
this list from 1934, so I can compare the CBH from then to the
This is quite interesting. One Oak for example, in Ocean
Ruskin Oak, measured 17'6" CBH in 1934. It now measures
27'2" CBH. That's
almost a 10' Cbh growth in 73 years! Neil this gives us a good
estimation of growth rates from this time span! There are some
Long Beach on the list with CBH in 1934, I'm going to go measure
and get some more comparisons. This is way cool stuff!

I had no idea
that there were so many 30-footers out there. Live oaks rule.
the possibility of larger girth bald cypresses, it sounds like
oak and sycamore are going to be the only real competitors in
30 Club and it sounds like the live oak has the advantage.
We Ents will be talking among ourselves about
our Over 30 Club and
others will assume we are referring to human members. Little
know. ENTS is way cool.

One note of caution on the Live Oak Society list, they include
with multiple stems that result from separate sprouts growing
together. Telling individuals with a single pith at ground level
fusions can be difficult with live oaks since they typically
low, but all the ones you've posted photographs of on the web
look like legitimate single stem trees to me.
Having a list of measurements from 1934 to update is great. The
of that Ruskin tree is amazing. Could any other factors like
flairs moving down the trunk as they enlarge have influenced the
measurements, or does the tree just have an enormous crown to
down the carbon with? I'm looking forward to hearing what you
for the growth of other live oaks. Definitely cool stuff.

These seem like reasonable growth numbers for this particular
Comparing the two circumferences you get a radius of 2.803 in
a radius of 4.325 in 2007. That works out to a change in radius
1.525 feet in 73 years or 0.2507 inches per year of radial
This compares well to the sample Neil Perderson dated for Larry
weeks ago. With a 4' 2" diameter tree being 134 years old.
0.187 inches radial growth per year on average throughout the
life of the tree. So a growth rate of 1/4" per year for a
is entirely reasonable.

The Ruskin Oak does have one main limb 5' Dia. near its base,
reviewed our measuring techniques when a low limb is present so
I got a
accurate CBH. The Friendship Oak, in Long Beach also is listed
registry, I'll report on it later as I have also measured it. I
multi trunk trees were in there own class, I've always felt that
shouldn't be included in with the single trunk trees. The Ruskin
located in an ideal growing environment. The tree has massive
a 153' crown. I mentioned this Oak on topica back on Jan 3rd. Ed
some photos on our webpage. The more trees I measure the better
accurate I become. The Live Oak Project I'm doing is challenging
the same time fun.
