Does anyone on the OB have experience measuring trees for either a state or national big tree registry?

I have a monstrous pecan tree in my back yard that I am thinking about trying to register, but it forks pretty low to the ground. I am uncertain if it would be counted as independent trees or not in regards to determining the dbh. Anyone with experience want to comment?

No idea for this, but as a standard when selling we measure diameter 6" above the ground. Sorry, thats all I can offer.

i think girth is measured at 4' or 5' from the ground. Also takes into account the crown spread and height.

I think my dad put and oak tree at our family land on the registry. Maybe he was just talking about doing it. This joker is bigger than any tree I've ever seen.

It's a shame so few people do this. The ones who do make the list appear over represented in some regions. Look at how many in the Vernon Parish area. An avid measurer lives there.

I know the dbh is supposed to be measured 4.5' from the ground, but there are conflicting rules when the tree forks below the traditional dbh height of 4.5'. I don't know if I would have to count it as different trees (hope not) or if I can still use the dbh from the smallest circumference below the fork, or the square of the sum of the circumferences of the individual forks.

Have you ever been to Vernon Parish... it's nothing but trees, and a wal-mart.

Right, but it's all medium textured upland and there's really nothing special about it's MTU.

How does one go about putting a tree on the registry? I've got an oak tree on my land in Bienville that looks like it's been growing since the late Jurassic

I am interested as well, there are a few in the swamp near my MIL's house that should be on that list, if they aren't already.

Can someone link the registry?

Some on there that I either never heard of, or was sure we did not have.

Measuring Guidelines


That's what I am thinking they will go by, but I'm not sure. If that is the case, then I blow the current record pecan tree out of the water by almost 100 points if I measured height (stick method) and crown spread (used google earth to conservatively estimate) correctly.

The circumference of my pecan is 21.5', so I have 258 points already, and the current record is 304 points.

Hard to tell size from this picture, but it's huge. The two front forks of it are each over 8' in circumference or around 2.6' diameter.
