There was an interview of David Milarch on NPR Radio this morning. https://www.npr.org/2012/12/08/166784040/saving-ancient-trees-with-clones Comments? I haven't heard that interview, but if it's at all related to previous ideology, Milarch may not want a debate on this. I wouldn't want to debate hi...

The base of a maple in North Portland Oregon. Been some years since I passed this working down the street, but I recall the width being 9 feet at the ground.

I found another youtube video where another man measurers the Carmanah Giant with a drone and claims it is "approx." 321 ft = 97.8 m tall. Reminds me of the guys who did the crude measure of Centurion trying to claim a height without proper gear. I'm not sure how accurate or inaccurate a drone is o...

Forget the brand I have. Will look later. It's in my van. I've been using a carbon fiber camera tripod to put my laser or camera on. I can't vouch for how tough it may be. I've taken it on some long redwood bushwhacks, but am fairly careful not to bang it around. With a laser in my pack, or camera, ...

The rare 260'+ class ponderosa grows on a high perched bench next to a small spring. Site elevation 3,250 feet. The LiDAR from 2013 shows the tree being around 250' so it appears to have grown considerably over the last 5 years. It's a younger old growth tree with an unusual double leader pointy to...

Mario, I appreciate your commitment to proper measurement methods for trees of the highest caliber. We all must be held accountable for our work, and especially for making extraordinary claims. Maybe this tree in question has exceeded 100 meters, maybe it has not. Hopefully these fellows will take ...

Yoav's claim of Centurion is unsubstantiated. I used to have a Trupulse360 for many years and I would say accuracy is more like +,- 40cm, especially at a distance like from the window Yoav used to measure the top. Perhaps my TP360 was a lemon ? He used the bottom 1/4-20 mount on a tripod which indu...

Brett, Is Centurion growing on sloping ground? The small differences like that between the 2014 Sillet measurement and the 2016 Thomas measurement can easily derive from differing definitions of the average ground level. The photos also show piles of debris around the trunk - how to define the aver...

Greeting all With regards to this latest claim for the height of Centurion, I’d love to say it is over 100m, even the 100.5m Yoav claims it is. However, I believe he’s got it wrong. Brett, I'm glad you chimed in. I was chatting about this with a man Aaron Poole on Facebook, and posted back and fort...
