Re: Biaowieza logging

Indeed there are no firs in Bialowieza, they mean spruces of course.

Re: Biaowieza logging

Kouta, "Europe’s tallest trees" is no bull- or bisonshit when looking for the tallest known specimen of still 4 species (among wich Quercus robur, Populus tremula and Betula pendula) and second to third location for 4 or 5 other species among wich Pinus sylvestris. So for native trees it is still a ...

Re: unknown oak

To me it looks more like a hybrid of Q.robur with another white oak species. The leaf stalks in typical robur are very short, with 2 tiny lobes (auricles) at the base . The leaves are deeper than in typical robur but the long stalks on the acorns are like robur , although I never saw such reddish ac...

Re: Dobroč Primeval Forest – new record for European silver

Hi Kouta, Nice to see your measurements of Dobrocky prales! The heightmeasurements are not that much different from the old ones from 1964, beech is even very near their 46 m. Very nice you found a new European sine-laser record for Abies alba in the end. Would be interesting if you gave a more comp...

Re: Tall trees measured in Spain

To the several questions concerning champion trees in Europe there is not a simple answere. Indeed in most European countries were there are champion tree organisations with databases the concentration is more on circumferenace than on height. This is easy to explain: the interest in big and old tre...

Re: Costa Rica: Corcovado National Park part 2

Bart, You have done a great job by researching for and measuring and documenting tall and big trees in Costa Rica and other Neotropical countries in the last few years and especially this year. I have followed and enjoyed your reports with nice photos. With a group of Dutch treelovers and arborists ...

Re: Tallest Northern California Eucalyptus

This tallest known Eucalyptus of Europe in Portugal was lasermeasured as 72 m (236 ft) in November 2010 by Dean Nicolle, a Eucalyptus specialist from Australia. See http://www.monumentaltrees.com/en/prt/centro/coimbra/4104_valledecanas/8314/ . So the height of 75 m (245 ft) reported in 2003 probably...

Re: The tallest tree of Germany

Kouta, I agree with your overview. Native broadleaves over 150 feet are very rare anywere in Europe, we know only of some grooves with European beech and European ash in Germany and Sessile oak in France of over 150 feet. Rarely Platanus x hispanica and probably Platanus orientalis will grow above 1...

Re: Tree Maximums - Genus of the Week: Abies (fir)

The Dendrological Aociety of Danmark gives a record height for beech in Danmark (about as far north as South Sweden) of 44.5 m, measured in 1995, so very probably with tangent method.

Re: Tree Maximums - Genus of the Week: Abies (fir)

Bob, Kouta, Indeed Norway Spruce is one of the more measured species, although the number on MT is not high. We still don't have important heightmeasurements from France, only some tangent measurements from Switzerland, Austria, etc. Also European beech, Pedunculate oak, perhaps Scots Pine, Small le...
