Data Wanted

Hello NTS-ers,

I'm currently working on a databasing project (a small project compared to my main one). So, please, if you have any data as to the most volumnous, tallest, girthiest, and most point-laden trees in the west, the east, Alaska or the Rockies/Great Plains, then please reply. I hope to share the end result here upon completion.

Cheers,

- Duncan

Hi Duncan,
Attached is last year's Atlanta Champion Tree list which Eli Dickerson sent me. He may have it in a different format and updated (there is a new city champion tulip tree, for example).
May the Forest Be With You!

Duncan,
Are you looking per species or just the tallest, widest, most point trees as a whole? Are you looking for US numbers only? Almost all the tallest, widest, and highest pointed trees are either Coast Redwood or Giant Sequoia. Below are a couple great links showing you the largest per species. Off the top of my head Hyperion (coast redwood) is the tallest, a shade over 380'. The Boole Tree (Giant Sequoia) is the widest at 113' at ground, and The General Sherman (Giant Sequoia) has the most points at 1321.

John,

I'm looking for the largest trees in each species, the ones with the greatest circumference, volume, height or AFA Points associated with them. This also spans four different regions, the west (which I'm currently working on, based on data from conifers.org, landmark trees and the AFA Website), the east, Alaska and the Rockies/Great Plains. The listing is, at the moment, only for the top 5 by volume in the west (General Sherman, Grogan's Fault, Quinault Lake Redcedar, Red Creek Fir and Queets Spruce). I'm currently defining the west as CA, NV, UT, OR, WA, ID, AZ and southern BC. I'm calculating AFA Points for the ones that aren't champions, but are taller or wider than said champion, and also listing height, circumference and volume (the last one if any calculations are available).

I'll try to convert the .numbers file to a format that this BBS will allow me to upload. Thank you for the data on the Boole Tree, as I was moving on to circumference after height.

There is a MAXLIST buried on this site with lots of eastern trees.

Beware of inaccurate sources of height and girth; AF register, state lists, etc. Basically, only numbers coming from or through the NTS are credible.

Here is the western Top 5 Superlatives list. Converted after completion into a version 1.0 PDF:

Duncan,
That's a nice list you have put together and it would be cool to expand on it with other species. What you will notice if you expand the list is that the info out west is more cut and dry and except for a few trees who's volumes are in question, the information is pretty straightforward. Once you start dealing with the species out east it gets more hazy. Determining the white oak with the greatest circumference can be hard, or the willow oak, or the tulip tree. You can find info on the "largest" by points but there isn't a lot of info, especially outside of this group, on numbers like that. You will find pretty extensive work here on max heights however.

Duncan,

It appears the conversions between meters and feet are not fully correct in your table. The foot is 0.3048 meters (https://en.wikipedia.org/wiki/Foot_%28unit%29) but you have used about 0.3043. For example, Brummitt Fir should be 99.76 m = 327,3, not 327.88.

Otherwise, a great work to put together these numbers!

Attached is a spreadsheet export of the Florida Dept. of Forestry Champion Tree database as of 11-7-2016. It doesn't contain the entries on non-public land. And the state DOF has implemented a rule that only trees with at least 80% of the current champion's points will be considered. They have since removed said less than 80% trees from their web interface, and I am not sure if they have removed these entries from their data set. If so then this spreadsheet contains data that likely no longer exists anywhere else.

Duncan-
An interesting idea!
It occurs to me for your Eastern portion, Bob Leverett has spearheaded a Superlative Native Tree database that might serve you well...you might approach him with the specifics of your study?
No charge for the data, if you complete your Cadre apprenticeship...; ~ }
