Re: Lake Julian Hollies.

Kouta, James, Indeed in the British Tree Register @ in this case means "measured at the height of". Standard height for measuring CBH and DBH is 5 ft (1,52 m) in the UK. In Belgium it is 1,5 m, in most European countries 1,3 m. The American height of 4,5 ft (1,37 m) is nowhere used in Europe. The pa...

Re: The Sunderland Giant

Bob, A very impressive tree indeed, like the Pinchot. You posted more info on both in the past. I like to post photos of two of the largest Plane trees (Platanus x hispanica) of (old) England, the UK. These plane trees are thought to be hybrids of your sycamore (Platanus occidentalis) and the Oriënt...

Re: some old trees in northern Germany

Steve, The tremendous girths of oaks, limes, sweet chestnuts, yew and plane trees in Europe are achieved by open grown trees in more or less cultivated situations. The largest limes (many in Germany, Switserland, Austria and the Chech republic) are often in villages and have got protection from the ...

Re: Kelheim Forest, Germany

Ed, Now I read your reply I better understand the term alleopathic.

Re: Kelheim Forest, Germany

Ed, Kouta, I also don't know anything about alleopathic characteristics of Beech. In the richest forest types in Europe (often riverine or along small streams or on older rich loam, clay, lime- or chalk soils) there are more treespecies like hornbeam, ash, lime, elm, maples, sweet cherry, poplar, et...

Re: Kelheim Forest, Germany

Doug, Lee and Kouta, The discussion is more something for vegetation and soil specialists, but perhaps Lee is that. In Europe the aspect of herbal undergrowth in forests is foremost related to soil qualities and secundary also related to the treelayer; precipitation, groundwater table and inclintion...

Re: Kelheim Forest, Germany

Doug, Thanks for this nice report you were finally able to publish! Funny an American is the first to do laser-hightmeasurements in this perhaps tallest stand of European ash and common oak in Germany. A pity you could not stay longer. I hope Kouta can visit Kelheim this winter or spring to measure ...

Re: Belgium: meeting on trees and tall beeches

Thanks for the compliments, Will, but we are just starting. We (Leo Goudzwaard of the forest research groupe of Wageningen University an myself) had a lot of discussion on mail about the measuring technique with the forest scientists in Belgium (Luc de Keersmaeker, Peter van de Kerckhove and others)...
