Re: St. Augustine, the Old Senator, May 2012

Ed, I don't think you are right with your term "garbage". Of course it is well known from dendrochronology and other tree- as well as forestry-science that there is no simple diamter - age relationship. But, when comparing trees of one species wich have grown in similar circumstances there can be fo...

Re: St. Augustine, the Old Senator, May 2012

Michael, Larry and others, Here is the article of John White. Estimating age of trees.pdf I think it is rather good, although you should not use its rules to get an accurate age of a tree. Much depends on growing conditions and species. The big oak with Larry is the biggest of Oak Alley at the Missi...

Re: Ancient trees: Britain's oldest inhabitants

Don, I never visited Andalusia except for a short passing through in 1977, although I was several times somewhat to the north in Extremadura. There are some big trees in this part of Spain, but because of the dry, warm climate and the history of cutting most forests as well as heavy grazing I think ...

Re: Tall oaks in the "Forêt de Bercé near Le Mans

Kouta, About the native distribution of Platanus orientalis in southern Europe I could not find much good information till now, also no good distribution maps. For example Euforgen doesn't publish an online distribution map of this species. Some information gives: http://www.sisef.it/iforest/content...

Re: Tall oaks in the "Forêt de Bercé near Le Mans

Kouta,

Indeed you are right that the hybrid plane tree is not a native tree. The oriëntal plane (Platanus orientalis) is native but only in the southeast of Europe (Greece and Turkey). I changed my text above a bit.

Tall oaks in the "Forêt de Bercé near Le Mans

In last April I visited France. I spent a week in the Morvan, an old, lower Mountain chain in Burgundy, some 150 miles southeast from Paris; for a great part the bedrock is granite with some slate, but especially in the northwestern part also limestone and marl can be found. Forests in the Morvan ar...

Re: Lake Champlain Valley and whopper cottonwoods

Bob, Beautiful and great trees, those cottonwoods! Those specimens seem to be planted. Is Populus deltoides much to be seen as a wild tree or more often planted? In Europe the related wild Populus nigra (we call it black poplar), became rare the last few centuries. Its native habitat are the banks o...

Re: The tallest linden of Europe

Hi Kouta, I suppose the old measurements in the book were by the late Prof. F. He probably only estimated heights or did them with an old stick method. He was more interested in the beauty of old trees and concentrated on big solitarians. His heightmeasurements were more indications. In the U.K. and...

Re: New Tallest Hardwood Species For California

Bob, The huge Platanus orientalis was measured around 2000 by Aubrey Fennell from Ireland. He told me when I met him at the European Champion Tree Forum (ECTF) in Bonn, Germany, at October 8 and 9. He is the principal measurer of the Irish Tree Register. He now knows the Haga Hypsometer / Altimeter ...
