Hoping someone might have a few bits of information on the maximum known height of Acer, worldwide. Information that is near 100% reliable. Last week, I discovered a bigleaf maple in northern California that is about 155 feet / 47.2 meters tall. It's not a huge tree. Although I suspect it could be fairly old. In the past few days, I've received notes, or met face to face, with researchers Van Pelt & Sillett, Will Blozan of the east USA, and Michael Taylor, California's champion tree program coordinator. Combined, they know of no maple in the USA over 148 feet. Van Pelt said that one reference to a 158 footer in Washington, was really more of a 148 footer, incorrectly measured. Blozan is aware of some 140 ft. to 144 ft. specimens in the east USA, and that anything found online said to be taller, would not really exist. I'm curious if anybody reading these forums has factual heights of any maples in other countries or continents, taller than 150 feet. Something that may not be online to find. Thank you.
Thanks Michael. Do you happen to know whether that one grows out in the open by itself, on the edge of a group of trees, or among other trees in a grove or forest? ....

I thought that the British record was a Norway Maple (Acer platanoides) growing in a park in Bath, it was reported in some of the newspapers earlier this year. Only 36.1 as against 37 metres for the A. pseudoplatanus Michael referenced, so only the tallest A. platanoides. According to one article "the tree is in a sheltered part of the park growing among other trees on a bank", see: http://www.independent.co.uk/environment/nature/tallest-tree-in-uk-declared-6661792.html.

Yep, as it says in the TROBI pdf, that's just the tallest Norway Maple, not the tallest maple of all. Just checked up the data on the 37 m tree (the TROBI website was down when I looked earlier today, but it's back up now) - it is among other trees in woodland. DBH 72 cm (2.26 m girth).
There are some pics of a 12m A campestre here: http://krapooarboricole.wordpress.c...e-de-la-bonniniere-saint-pardoux-deux-sevres/ and I think this one is even bigger (although no height given) http://krapooarboricole.wordpress.c...champetre-de-beugin-pas-de-calais/#more-32599 I was looking for a forestry site of champion trees for France but didn't find it. 37 m is one massive sycamore!
Some European champions of over 30 m; all accurate laser or tape drop measurements: Native: Acer pseudoplatanus: 39.0 m, Perucica Nature Reserve, Bosnia (source) Acer platanoides: 37.2 m, Białowieża National Park, Poland (source) Cultivated: Acer macrophyllum: 35.5 m, Arboretum Tervuren, Belgium (source) Acer saccharinum: 33.6 m, Arboretum Tervuren, Belgium (source) Acer rubrum: 32.0 m, Arboretum Groenendaal, Belgium (source) Acer saccharum: 31.6 m, Arboretum Tervuren, Belgium (source)
Appreciate the feedback here and on other arborist forums. Fro what's been shared, it looks like it's worth going back for another complete measurement this autumn. Hopefully by mid-October. ...
