Hi Rob

Wow at least 6 trees over 60m! How long are the leaders of these trees Rob? Any noticeable wind damage from last winter?

I saw these trees in the dark with the car headlights and kick myself for running out of time to see them last year, will have to return soon. Looks like the weather will change next week so may hold off holiday there, until another anticyclone arrives to ensure good weather in Wales.

Will be at Europe's largest forestry show on Sat in the Midlands so may look at impulse lasers and the new model out and may or may not be tempted! Trouble is that would I have the time to use it? 10 years ago definitely would.


RedRob, op 2014-09-16 17:30:36, zei:
Hello Stephen, just run out of time with fiddling with the maps.

Six trees of 60 metres, the lot I bet are 60 metres if you could find windows in to measure them, the whole stand of probably nearing a hundred trees.

RedRob, op 2014-09-17 17:00:58, gewijzigd op 2014-09-17 17:26:35, zei:
Stephen, your visit on Saturday, I wouldn't be tempted would be my advice. Look, ascertain what you want but don't buy or else you will be robbed blind. Try sourcing the same instrument in Holland or the continent, you will get the same thing much cheaper, ridiculously cheaper. I got the Forestry Pro that I bought for half the price that they were being advertised over here. I couldn't have justified £500 odd quid for the laser but I am happy now with what I paid, I think that I have measured enough trees to justify it. Don't think that I could have ever have justified the price of one of the Impulse lasers, not for the number of trees that I have found and measured and am now likely to find in the future. I think you would have to be travelling the world measuring or a forestry professional or professional tree measurer to justify the Impulse. Judging by Karlheinz's and Kouta's recent measuring of the 59 metre Norway Spruce, the margin of error is not too bad for the Nikon Forestry Pro. We don't know if Kouta and Karlheinz chose precisely the same spot on the trunk to measure to so this is another error margin also Kouta may actually have had the correct spot and Karlheinz may have just been a tad high, we don't know but some of this probably accounts for the small difference.

Stephen Verge, op 2014-09-19 07:17:38, zei:

Many thanks for your sensible advice. Just a query if you purchase something from abroad, UK dealers are often rather awkward when it comes to service and repair? What do you think?

Will look and not touch and find out prices, with me I can offset against tax which is helpful.

Perhaps now I can return to Scotland as it remains now in UK! To measure big conifers!



RedRob, op 2014-09-20 15:51:42, gewijzigd op 2014-09-20 15:52:27, zei:
Hello Stephen, the Nikon Forestry Pro that I purchased has/had a 1 year manufacturers warranty which expired a year ago last July. A year on it is still going strong and hoping that it will not break. If it does at any point, it will probably cost nearly as much to repair as buying a new one so I wouldn't be getting it repaired and wouldn't be buying a new one. I think it comes down anyway to how you use the laser, I am ultra careful with mine, I don't let it dangle about from my neck letting it swing around as I am walking about, I hold it in my right hand horizontal and cushion it against jolts as I walk. As I have said umpteen times on here before, I roll my finger over the buttons at the top rather than pressing on them, I found early that this cuts down on agreat amount of laser movement at the time you press but it also cuts down on wear and tear on the buttons as well. I think with simple care and use, you can look after the laser and make it last. I always carefully clean the case and lens when I have finished with it before I put it away and so the laser still looks like new even though it is over 2 years old.

Wow amazing!

Rob ever thought of purchasing one of those poles used in surveying so you can measure above the vegetation and add on accurately the remainder?


Stephen Verge, op 2014-09-17 07:04:18, zei:
Hello Owen

A very impressive stand of trees for that part of the country! It may be that the North Sea moderates the climate somewhat here? Although to a lesser degree than say the New Forest on the channel coast? Any Sitka there?

There is a Douglas just north of Henley, Oxon (close to me) which is almost as tall planted 1917 and still growing (on chalk!) Possibly tallest tree in Oxon if not Bucks and Berks.


RedRob, op 2014-09-17 16:48:31, zei:
I agree with Stephen, abit of a surprise but an impressive one. The Grand Fir is very impressive. I do abit of plane spotting and have been to RAF Lakenheath several times and the soil there is like dust-sandy,dry. As said to someone, amazing that the conifers in Thetford Forest can survive in the soil. I imagine it will be very dry at the moment as it has been very dry in Eastern England for the last few weeks.

TheTreeRegisterOwenJohnson, op 2014-09-18 17:53:23, zei:
Yes, I think the North Sea does help conifer growth in Norfolk - the most stressful conditions are often when there's a dry hot easterly wind and this will be cooler (and moister) when blowing off the North Sea.

There aren't any Sitkas at Weasenham Woods but at another of the Coke family's 19th century experiments in continuous-cover forestry, Fulmodeston Severals, there is a (youngish) plantation with trees to 37m. Again rather remarkable, as this tree really doesn't like it hot and dry.

TheTreeRegisterOwenJohnson, op 2014-09-18 17:55:04, zei:

I remember you mentioning the Douglas Fir near Henley before. I think there are a few of your records that have not yet found their way onto the Tree Register, for one reason or the other - this is one. It certainly sounds like the tallest tree in the Home Counties area - perhaps you would be able to add it to this site?


Stephen Verge, op 2014-09-19 07:11:48, zei:
Thanks Owen and Rob

Of interest to tree growth and climate from the Met Office averages 1981-2010, (On climate section on Met Office site can't post hyper link here) shows average rainfall of 700-800mm for North Norfolk, slightly less than The Chilterns where I am, 800-1000mm over higher parts, hence growth of conifers is slightly better than other Home County areas. Also shows why conifer growth/productivity is some of the best in the cool temperate world in Wales and the North West UK.

Owen I am reluctant to submit tangent measurements due to their possible inaccuracies, which may or may not be correct, but would be I hope within + or - 2m. Until I get a laser?


Do you know the giant Sessile Oak near the Mezel Depot in Windsor Great Park next to the park junction? Mentioned in Alans book as 125ft x 20ft (magnificent as any) Probably the oldest oak I have encountered, because adjacent Sessile about 390-400 years based on a solid ring count! Will do report on this for monumental trees soon. It says avenue was planted in 1751!

Het is mij niet duidelijk wie aan de beschrijving een verhaal over meten op verschillende hoogtes heeft opgeschreven. Mijn ervaringen stroken daarmee. Ik heb nadrukkelijk het centrum van de boom opgezocht, maar daar alleen meten is hachelijk. Het is de kunst om het meetlint strak te houden en steeds te letten op 1.30 meter. Mijn eerste meting kwam uit op 6,57 meter en mijn tweede en derde op 6,56 en 6,49. Ik probeerde met alle macht het lint strak te trekken op de middenpositie. Uiteindelijk lukte me dat (denk ik) en ik kwam op 6,38 meter. Ik had van tevoren wel wat gegevens verzameld en in mijn gegevens stond een hoogte van 6,10 meter. Ik kan die hoogte absoluut niet aan mijn praktijkervaring koppelen.

Jeroen Philippona, op 2014-09-17 20:54:54, gewijzigd op 2014-09-17 20:55:47, zei:
Hallo Wim,

Het stukje tekst over het meten is van mij. De laatste keer dat ik er aan het meten ben geweest was dit voorjaar samen met Corine van Dun, hoofdredacteur van Bomennieuws. Bomen op hellingen zijn lastig te meten, als je de methode hanteert van het centrum van de boom, waar de boom ooit ontkiemde of werd geplant, kom je bij heel dikke bomen op steile hellingen soms onder het hoogste punt rond de stam uit. Bij bomen op zo'n locatie is het aardig op verschillende hoogtes te meten. Wat je bedoelt met die hoogte van 6,10 m is me niet duidelijk.


Wim Brinkerink, op 2014-09-18 08:58:31, zei:
Hallo Jeroen,

Lees voor 6,10 svp 6,18. 6,10 zat onterecht in mijn hoofd, dat moest 6,18 zijn. Ik had een overzichtje meegenomen met maten zoals ze op MT staan. Maar als ik jouw verhaal lees dan zou je toch een omtrek van 6,46 m moeten registreren? Of is de eerder door jou beschreven meetrichtlijn niet zo algemeen? Ik hou me er in ieder geval zo goed mogelijk aan, maar aarzel om 6,38 aan te geven. (wat volgens mij een juistere meting dan 6,18 zou zijn). (Overigens verklaart dat nog niet het verschil met jouw meting van 6,46 m.)

A technical point: as these trees are seed-grown (self-sown), they are Fagus sylvatica f. tortuosa, and not the cultivar 'Suenteliensis', which to be true to name can only be propagated clonally by grafting.

Martin Tijdgat, op 2014-07-23 22:03:10, gewijzigd op 2014-07-23 22:04:25, zei:

Thanks for this. You are absolutely right; this is the naturaly occuring forma tortuosa. I had the same type of discussion with Fagus sylvatica 'Asplenifolia'.or 'Laciniata'. This leafform also occurs naturaly and has been grafted under a few different names.

Maarten Windemuller, op 2014-07-23 22:17:54, gewijzigd op 2014-07-24 08:50:18, zei:
Thanks, that's true, it's not a clone. I changed name. New problem: I cannot get a small "f" before tortuosa. The system automatically generates a capital F. Will ask Tim to change it. But what must we think about the oak, MT nr. 18706? :)

Tim, op 2014-09-17 19:58:00, zei:

I changed the cultivar 'Tortuosa' in subsp. tortuosa, and registered this tree as such.

I also made it so that cultivars/varieties always get a capital letter (as was the case), but subspecies don't.

Kind regards,

Hi Tim,

Thanks! A bit of clarification though, re "I also made it so that cultivars/varieties always get a capital letter (as was the case), but subspecies don't".

The ranks of subspecies, variety and forma are botanical, and governed by the International Code of Botanical Nomenclature; they are always in italics and begin with a lower case letter, and must always show an indication of which rank is being used (the rank NOT in italics!):

Pinus nigra subsp. salzmannii

Pinus sylvestris var. hamata

Fagus sylvatica f. tortuosa

Cultivars, and cultivar groups, are governed by the International Code for Nomenclature of Cultivated Plants; they are not in italics, and begin with a capital; individual cultivars are in single quotes, groups of similar cultivars not in quotes:

Acer platanoides 'Crimson King'

Acer palmatum Dissectum Group

Hope this helps!

De Villa dateert uit 1742, maar hoe weet je dat de lindes ook uit 1742 dateren? Zijn het heel zekere winterlindes, ik zag ze tot nu toe aan voor Hollandse lindes maar heb er niet heel goed op gelet. Leo, Maarten en Simen Brunia waren tijdens de Donateursdag van de Bomenstichting vorige week ook present bij deze bomen, misschien hebben zij er ook op gelet.

Apologies, the measurement should be 20 August 2013, forgot to change from 2014.

Ernie certainly loved these trees so much that he was buried amongst them with his dogs but these have been the single most disappointing trees that I have ever measured. Planted in 1860 and 37 metres in 1957 I was hoping that the measurement was abit out and that they had spurted in growth and there would be 60 metre trees in Yorkshire. Even with the growth rate of 37 metres in 1957 they could have been 56/57 metres. What a disappointment when I got there and measured with the laser.

RedRob, op 2014-09-15 17:23:12, zei:
Hello Owen, this is/was the tree at the top of the stand where the path turns to the left, straight in front of you with Ivy on the trunk. I could only get 52 metres for this tree but I couldn't see the top at any point with a view of the base. Assessing from further down where I managed to see the tip, I think I will have missed about twenty feet off, every tree that I have measured in this stand is/was 60 metres so I will assign 60 metres for this one. It certainly was not 14 0r 15 metres taller then 52 metres.

TheTreeRegisterOwenJohnson, op 2014-09-16 19:35:10, zei:
I think the tree in the lower photograph is one I got 60m for - on the left of the footpath after you've gone round the bend and continued climbing. The one I made 61m was about 50m below this, a few metres away from the bend in the path (o the SW side) and with a lot of ivy. Maybe it has been removed since.

RedRob, op 2014-09-17 16:49:41, zei:
Hello Owen, both photographs are the same tree, I couldn't get it in one photograph so took two photos like this.

Ik heb de betreffende boom gemeten op 16-9-2014. Wat mij betreft is meten op 1.30 niet reëel of mogelijk. Op circa 1.10 meter loopt een tak uit, waardoor je volgens mij op 1.10 meter moet blijven. Ik heb op die plek 5,27 meter gemeten. Ik vind de sprong naar mijn voorgangers erg groot(die nb op 130 cm hebben gemeten!), maar...ik kan niet anders dan dit maar opvoeren.

Difficult measuring conditions on the slope in the upper part of the Waterloo Grove, difficult on many or most of the trees to see base and apex tip together. I did manage to measure three trees cleanly through gaps and this was the tallest. The others were also 60 metres. I didn't explore enough further up last year on my visit and thought that there may be a taller tree in the higher part of the stand but I think they will be all around this height in the higher and slightly more exposed part of the stand. The tree looks like just a trunk but the sun was shafting through the trees and I was photographing towards it.

RedRob, op 2014-09-04 16:23:53, zei:
Need abit of help with this one, more photos available if required. The trunk pattern didn't seem smooth enough for Abies Grandis, the foliage not flat enough and the shape not quite right for conventional Grandis that I have seen? What is this tree?

Conifers, op 2014-09-04 16:49:00, zei:
The bark looks OK to me for Abies grandis, it gets like this on mature trees. What foliage was it you looked at, if it was windblown upper crown foliage, then that's normal for the needles to be more assurgent.

RedRob, op 2014-09-04 17:14:59, zei:
Hello Conifers, the tree had lower branches sweeping down and I photographed the foliage close up which I have posted if you look at all the photos. Not seen any really big, old Grand Firs as close up as this so not seen the ribbed bark like this before. The terminal foliage on the shoot ends around the buds also seemed abit more rounded than other Grand Firs that I have seen but maybe this is with age as well, I suppose it is what you have seen yourself which you compare to.

Conifers, op 2014-09-04 18:27:52, zei:
Hi Rob,

Thanks! What the foliage does fit in that case is the interior subspecies Abies grandis subsp. idahoensis (from east of the Cascades crest); this has somewhat assurgent foliage throughout the crown, not just at the top of the tree. The only problem with this is that it is a smaller, slower-growing tree than coastal subsp. grandis, a 50 metre specimen would have to be ancient.

Abies grandis subsp. idahoensis grades into Abies concolor in the south of its area, including (in the southwest of its area) into Abies concolor subsp. lowiana, which is also a large, fairly vigorous tree (though not as vigorous as subsp. grandis). But it does perhaps offer a potential source location in the southern Cascades in Oregon.

It might be worth contacting the FC to see if they have planting records for the plot. A lot of the older plantings of Abies grandis in Britain are of the interior subspecies (being smaller, it was much cheaper to collect the seed!), before foresters discovered how much slower and poorer its growth was compared to coastal origins.

RedRob, op 2014-09-05 16:19:48, zei:
Hello Conifers, I had never heard of Idahoensis, learn something new every day. From reading the description it does describe these trees, the foliage just didn't seem flat enough for conventional Grand Fir (quote 'stongly flattened' from one site) and it seemed to taper around the buds and recurve more than the usual Grandis (you can see it in the photos) which I have seen myself albeit I won't have seen as many examples as people like Kouta, yourself, Owen etc. Any comments from anyone else, Owen, Kouta, Jeroen, Karlheinz?

RedRob, op 2014-09-05 16:48:19, zei:
Just uploaded a further foliage photo of this tree taken up tree. As said, still might be wrongs but it just didn't look fully right for Abies Grandis, the rounded tapering recurving needles around the terminal buds.

Stephen Verge, op 2014-09-06 07:48:01, zei:
Hi Red Rob and Conifers and all

I'm back after my busy summer!

Foliage is typical for Grand Fir east of the Cascades. Most seed imports into this country up to the 1960's were of this interior form. I remember seeing this tree last Sept, so 52m, yet another!!

RedRob, op 2014-09-08 16:09:29, zei:
Hello Stephen, welcome back, missed reading your posts. This does look like Idahoensis, this one wasn't even the tallest, that was 53 metres for the other one that I put on here the other day. Vyrnwy, cloud and mist was hanging over the lake and it may be fairly mild comparative here, would this mean that Idahoensis would possibly have more potential for growth here than east of the Cascades which I imagine is certainly colder in winter and drier?

Stephen Verge, op 2014-09-10 07:53:32, zei:

Most of Grand Fir in the UK before the 1960's came from just east of the crest of the Cascades, little came from the actual Pacific Coast so most of the oldest and tallest are probably of inferior growth rate, but likely to grow faster in UK. I was not aware this has been regarded a sub species, is this recent?

I may go on holiday later this month to find some more giants, have you been on holiday there too?


RedRob, op 2014-09-10 16:05:18, zei:
Hello Stephen, are you going on holiday to the Pacific Northwest or to look for trees in this country? I was in North Wales and Powys last week but there are areas in central Wales that could have some tall trees if you want some ideas? The Elan Valley area, Alan Mitchell recorded 50 metre Douglas Firs there way back in 1979 I think it was. I have located some myself which I had hoped to visit but never made it down as far.

Stephen Verge, op 2014-09-10 20:38:46, zei:

Hope to go back to North Wales if the weather holds out later this month. Find some big trees and maybe pan for some gold if there is time!

Perhaps try to look at the Elan Valley on the way but its quite far from North Wales.

How is the tall Douglas in the Conwy Valley doing? I left too late one evening and only saw them in darkness with the headlights on!

Hello Stephen, will be reporting on the Betws trees from this year's visit when I get around to it over the next few days.

Before I visited North Wales this year I spent a considerable time scouring the valleys of North Wales on Google Maps looking for dark shadows and long shadows from the satellite and then looking on Street View. Really don't think that there are any more really tall stands in the Snowdonia area, Coed Y Brenin, Conwy Valley, Vyrnwy, Aber Hirnant seem to be the places. I drove all over last week scanning various valleys in the Berwyns and up around Betws and didn't come across anything taller or anywhere near. I have been to the forests around Corris on a previous visit and the trees there are not exceptional. An area where there could be tall and unknown trees is central Wales, Elan Valley and further down, Twyi Forest and the forests near Llandridod Wells. Owen sent me the records but I cannot find them in my emails so I have just asked him again, Alan Mitchell recorded big Douglas Firs back in 1979 and if they have kept growing at a reasonable rate they could be pretty big now.

RedRob, op 2014-09-12 16:48:28, zei:
The estate at Llanwrthwl was called Glanrhos SN973641 Owen has informed me again. put Glanrhos estate into search. I have been up and down the lane and there is a group of tall conifers which look like Douglas Firs but they don't look super tall and are in an open, exposed position. Not sure if these will be the trees which Alan Mitchell recorded or not? This group in the Elan Valley is a group that I came across whilst searching, on Google Maps they do look pretty tall but there looks to be abit of distortion in the camera which may be fore-shortening them in height when viewed from the bridge. They are in the bottom of the valley so should be pretty sheltered. Stephen, if you do make it anywhere down this way in passing this group would be worth stopping at. I haver just been riding up and down roads in Tywi Forest and the A44 between Llanwrtyd and Abergwesyn and over towards Aberystwyth and had longer range views and the conifers look ordinary.

Stephen Verge, op 2014-09-13 09:24:31, zei:
Hi Rob

Elan valley looks interesting, it may be a bit far out to travel to North Wales, but I could do a detour.

Dyfi valley was an interesting place for big plantation grown conifers. Sadly as usual The FC felled the best stand of Hemlock about 10 years ago. With good soils and shelter the forest is very productive here.

It will be interesting to see how Dothistroma needle blight is progressing there in North Wales it was partly defoliating conifers and causing them to lose vigour.

Hope to make it back there if the weather remains good.


RedRob, op 2014-09-13 16:49:48, zei:
Hello Stephen, I really don't like to hear the talk about needle drop, especially connected with some more trees that I have yet to post on.

I have been up the Dyfi Valley on Google Maps and there is large scale felling viewable. If you put 'Pantperthog' into Google Maps and travel about a quarter of a mile north on the A487, there is a line of tall trees that I think may be Douglas Fir. Look big but not massive but abit hard to truly judge on Google Maps as I have seen distortion on some views. These are the tallest that I can find in this area, beautiful countryside though, wonderful smooth roads (as they all appear to be down there compared to the potholed lot we have up in Yorkshire) sweeping through deep, wooded valleys. Visited King Arthur's labyrinth at Corris in 2006 and it was great countryside.

If you want a nice little B&B Stephen, I can recommend one near the north end of Lake Bala, a little gem with great food and incredibly reasonable. It provided a great, central base for my visit.

In a spot of bovver and need abit of help. Whilst looking up at the 60 metre Douglas Fir at Vyrnwy (next to ex 64 metre champ) I fired the laser off across the ravine to the group od spruces on the other side and this was the tallest. Came to a decision but just want to double check? Can it be identified from the blowing the photo up to see foliage and bark pattern?

RedRob, op 2014-09-14 16:24:07, zei:
Hello Stephen, the Welsh weather changed in a very short time and it was tippling down by the time that I took this photo but I think the Douglas Firs that you were referring to have been caught in this photo in the background. I stood up the hill on the road and looked back over to assess and the trees down near the road definitely physically looked the tallest when viewed from the horizontal up the road. The land rises up the valley and the trees near the road looked level with the higher trees, I suspect that they will be 51/52 metres, the tallest tree that I measured on the road definitely the tallest of it's line, dfinitely 54 metres but could be 55 metres.

RedRob, op 2014-09-14 16:54:43, zei:
Sorry Stephen, just re-read your post and it was you further up the hill and not the trees. You must have been in the same spot as I was if you were on the road.

Beautiful tree, how come some of the Norways remain narrow in shape and clothed with branches way down and yet others are very open and lose their lower branches? There are both types up in Yorkshire, they look quite different at times? Do they vary according to what area they originated from?

KoutaR, op 2014-09-13 18:33:32, zei:
I believe that the main reason, why this tree has foliage almost along the whole lenght, is that its one side gets plenty of light (the tree is standing at a creek). But branching patterns of Norway spruce also vary genetically, also within a single stand.

Stephen Verge, op 2014-09-14 10:43:15, zei:
Yes nice tree

Just wondering how the age was calculated. Norway spruces are lucky to live 200 years in U.K.. It may be that fungal pathogens may be less aggressive in continental climates with colder winters?


KoutaR, op 2014-09-14 11:24:35, zei:
The www-site of the park says "Ihr Alter schätzt man auf etwa 380 Jahre" = "Its age is estimated as ca. 380 years".

I am not sure but I think I saw boring traces in the trunk. It is definitely much older than 200 y. Spruce cannot attain almost 5 m girth in 200 years in Germany. The UK's climate is apparently not the best for Norways spruce. Possibly too ocean. Fungal pathogens may be one factor, indeed. "Conifers" knows more about this, I once has a short e-mail discussion with him.

Hello Stephen, the tallest tree that I found in Aber Hirnant is the one on the left in the distant photo, 54.2 metres although the base was difficult to see and I had to estimate the location so it could be near 55 metres. Is this the tree that you found, near the group of houses with the Sequoiadendron in the garden?

Stephen Verge, op 2014-09-14 10:51:41, zei:

Glad you found them. Could be my tree but was further up the hill when I recorded 55m. Probably some of the oldest Douglas in Wales, some close to 1.8m in diameter. I reckon planting was around 1860-1870? tried to count the whorls but too difficult. Some of these trees could have in excess of 40m3 each!

Jeroen said that this Larch was just up form the path (is that correct Jeroen, did I remember correctly) I think likely that this is the same tree, measured 43.6 metres but to a point on the trunk above the Bracken, estimate about 0.5 of a metre to the point, this tree is 44 metres or just a fraction over. Didn't look incredibly healthy, quite sparse.

Hello Owen, didn't strike me as any form of Canadensis and have seen quite a few types now, leaves really prematurely browning and trunk not fissured but seemed smoother with brown patches on it.
TheTreeRegisterOwenJohnson, op 2014-09-11 17:52:48, zei:
The smooth bark is right for some balsamifera clones ('TT32' is very smooth but has a different habit, I think 'TT37' is similar in bark). The premature autumn colour is due to a fungal infection which the balsam poplars and the wild Black Poplar get, but not the Black Poplar's common hybrids.

Hello Kouta, thank you for the short article, very interesting. A graceful tree in shape, this one with branches down to near the ground. Surprising that the Cragside Nordmann is nearly as tall, 49 metres. Perhaps eventually some specimans in Wales or Western Scotland could be the tallest, there was a 2005 42 metre speciman at Bodnant Gardens where I was last week but I wasn't able to measure as the area had been fenced off with no publice permitted. We need some tree measurers from the Caucasus area on here to find trees to measure.

KoutaR, op 2014-09-10 16:09:58, zei:
Hello Rob,

I think the UK has at least greater potential for tall Nordmann firs than the Borjomi Reserve, because of milder and moister climate. The westernmost part of the Georgian Greater Caucasus may have taller trees than the Borjomi Reserve, but the real giants are likely still further west, in Abkhasia and the Russian part.

I agree that it would be the best to get information from local forest researchers. I tried to contact one but did not get answer (not surprising).

As most members likely know, great heights up to 85 m have been claimed for Nordmann fir (Abies nordmanniana). These super-tall firs have been reported mostly from the Russian western Caucasus and Abkhazia. I discussed Nordmann fir heights with Prof. Peter A. Schmidt, a renowned Caucasus expert. He said giant firs can be found in the western Greater Caucasus, particularly in the Russian part and in Abkhazia and he has not seen any giants in Georgia (excluding Abkhazia, which is not in Georgian control anymore). According to him, the Georgian floras and other sources give the max. height of the species as 50 m. Thus, I did not expect to find any super-tall trees in Borjomi Reserve, and the fact that the tallest tree I found was only 50.2 m is no argument against the possibility that the claimed super-tall trees exist.

While in the park, it became clear to me why there are no super-tall firs: the vegetation clearly shows that the climate is way too continental and dry for optimal tree growth. The southern slopes are covered with low forests of such drought-resistant taxa as Quercus petraea ssp. iberica, oriental hornbeam (Carpinus orientalis) and Scots pine (Pinus sylvestris). The northern slopes are moister but Scots pine is still very common, along with Caucasian spruce (Picea orientalis) and common hornbeam (Carpinus betulus); the forest floor is fairly open. Along the Georgian Black Sea coast there is a mild and moist “rainforest” strip but the fir does not grow there. As a conclusion, it remains a mystery whether Nordmann fir can really reach 70 or even over 80 m.

Looking through your site [rpdp] I discovered interesting thing that 'my' poplar which I desribed in previous post, from Zalesie, may be the largest with crown that grows very highly - more than 10metres, maybe even 15, depending upon estimations.

That is why it should be found in new album of famous Krzysztof Borkowski's book, hopefully He will know about this great tree.. And I really recommend you to visit this place (obviously in future, maybe for a few years) because probably it is worth visiting. And I could feel like an adventurer discovering this poplar, but it is very important to desribe this tree as a natural monument, I will strive for this. Best regards and thanks for your work for dendrology! :)

Przeglądając ogromne topole białe na stronie zauważyłem, że z topoli, które rozgałęziają się ok. lub powyżej 10 metrów to 'moja' topola z Zalesia jest najwieksza. W dodatku mogła rosnąć przez cały czas w otoczeniu 'konkurencji' klonów i dębów, dzięki czemu ma taką rozłozysta koronę i wielki wzrost (wysokość). Pan Krzysztof Borkowksi powinien w kolejnym albumie polskich drzew ją umieścić, bo naprawde warto. Zawsze można poczuć sie jak odkrywca, bo najwyraźniej wszyscy o tym drzewie zapomnieli, skoro nawet nie jest pomnikiem przyrody.. Polecam zobaczyć w przyszłości i dziekuję Panu za te wszystkie informacje o drzewach, odkąd odkyłem te wszystkie strony w I klasie liceum, to od razu chciałem mierzyć i fotografować.

Superb tree, tallest in Europe (is it the tallest in the world measured?) Great to have laser measured trees, a 30 metre Juglans Regia was reported at Glen Lyon about a decade ago but turns out to be 20 metres laser measured, another in Suffolk was 27 metres but is 24.8 metres. This one is the tallest and accurate. Always have a soft spot for Juglans Regia since a holiday in Corfu in 1977 when I was nine and there was this beautiful tree right outside the balcony which I was fascinated with because of the aroma it gave off in the heat.

According Prof. Dr. Hans Pretzsch (in Enzyklopädie der Laubbäume), the species reaches 35 m in forest. Such heights sound extreme to us because walnut is not(?) planted in forest stands in our countries. This is the tallest laser-measured specimen so far I know, but I have no doubt that taller ones exist. Remember that the natural area extends over the Himalayas to Japan!

A 30-metre tree shrank to 20 m after a laser-measurement - quite extreme! I have encountered 40m -> 30m.

Velvet maple (Acer velutinum) has been claimed to reach heights up to 50 m in northern Iran. The tallest maple I found in Lagodekhi Protected Areas, Georgia, was only 39.7 m (fluweelesdoorn (Acer velutinum) '19217').

However, the easiness of finding almost 40-metre maples and the fact that I found all the trees without any local help suggest that the species may reach well over 40 m even in this park. Moreover, the growing conditions are better in northern Iran, the winters being milder and the growing seasons longer. Compared with sycamore maple (A. pseudoplatanus), velvet maple generally seems to develop a beech-like straight trunk, which suggests a greater height potential than that of sycamore maple. Thus, my findings in eastern Georgia are no argument against the possibility that the species could reach 50 m. Ten years ago, I had the opportunity to visit some forests in northern Iran and I saw larger velvet maples there, though I cannot estimate their heights (some of my earlier estimates have proved to be totally wrong since I started to measure with a laser). I believe velvet maple is the tallest maple species of western Eurasia, but whether it really reaches 50 m remains a mystery. 50 m would be taller than the tallest bigleaf maple (A. macrophyllum) in California, which is 48.1 m (

Hello Andrew,

You are doing a great job by posting so many beautiful big and old trees in Poland at this website! To my opinion the girth measurement of this oak was done the best in 2013 at 0,8 m: we recommend with trees with this form to measure it below 1,3 m at the smallest possible point, the 'taille', like advised at the measurement page: . So best would be to measure this also in 2014 and everytime you measure the tree, because this can be compared and gives an indication about the growth of the tree.

Best regards,

One cultivar of Catalpa x erubescens, 'Purpurea', has leaves deep purple for a few days, then green, and its flowers have more purple spots, giving them a pale lilac cast. In England, the common clone is the original one, 'J C Teas', which has less of the purple pigment. This one looks the right colour to me for 'J C Teas'.

Conifers, would you be able to edit the co-ordinates here, I cannot get the map tp shift at all. This tree is just a fraction down to the right of the Coast Redwood. Thanks. Made abit of a cock up with this tree last night but cannot now change, should be around 7 metres girth and exactly 49.2 metres height.

Site slowdown

as you probably all noticed the site got slower to even unreachable the last days.

I found the cause and have a solution in mind that I will try to implement today. This should cause the site (especially the image overview pages) to be faster than before, but in the meantime the overview pages per country/province/municipality will not list any images. The image pages as such (not the overview pages) will remain accessible and you can continue to use the site without restrictions.

Just so you know these empty image overview pages are intentional and temporary.

Kind regards,

everything should now be relatively fast again and working.

Conifers, op 2014-08-14 19:33:13, zei:
Thanks Tim!

One other cause of slowdown - the flickering numbers on the home page (number of registered trees, etc.) slow loading down quite a lot. I have also read that flickering images like this can be dangerous for people with epilepsy (they can trigger an epileptic fit). Maybe make the numbers appear in the final totals from the start, without the 'counting up'?

Tim, op 2014-08-15 16:34:41, zei:
Hi Conifers,

I have to disappoint you but these moving counters don't slow down the site.

The actual numbers they stop on after moving are already known as soon as you see the page, and getting these numbers is much less than a fraction of a millisecond as it doesn't involve any actual counting. The moving numbers that you see then is just a simple animation that is done at the client's side to make that main page appear more dynamic (like see, the database is ever growing).

I made the color of the counters somewhat less black to soften the contrast.

Kind regards,

Hi Tim,

sorry for taking your time, but I added more or less in 10th August a few great trees, generally oaks. Then, 2 weeks later, I went to this place to measure and make photos of the Giants. But it turned out that an image of the localization and respective specimens was very different (than I have read on the Net and in forestry, data was from about 1990) so I DELETED earlier-added trees and I once again added trees from this place, but with completely new localization (it is here - manor house and in vicinity of this place )

The problem is that I can see in statictics-site, for instance the largest in Łódź voivodeship) old records, data before deletion.

I have a lesson for future to firstly measure and then post the trees but can you repair it or nothing is to do with this thing

Best regards,

Hello Mairie,

this is a magnificent tree, but it is no Sequoiadendron giganteum. It's a Sequoia sempervirens. And if the girth measurement is indeed correct, it would even be the largest specimen here in Europe. It sure looks like a heavy trunk. Congratulations...:-0...!

Agree totally with Frank, what a magnificent Coast Redwood, second tallest recorded in Europe at the moment. The photo with the people walking past really gives a context, a perspective of it's size.

Bonjour Mairie,

I hope you don't mind that I have changed the species from Sequoiadendron giganteum to Sequoia sempervirens, wich it very clearly is.

We like to have the right information on this website about species and measurements.

This specimen is extra interesting as indeed being probably the largest and second tallest Sequoia sempervirens tree in Europe we know of.

It seems to be a rival of the largest Seqoiadendron in Europe regarding to total woodvolume and could be one of the largest trees in Europe already.

Best regards,

Jeroen Philippona

Hallo Tim,

Ik heb een verkeerde foto geplaatst bij de boom noordelijke catalpa (Catalpa speciosa) '9010'. Deze zou met het er op geleverde commentaar naar hybride trompetboom (Catalpa × erubescens) '19141' moeten worde verplaatst. Kan dat? Of wil jij het svp doen?



Wim Brinkerink, op 2014-09-01 19:31:56, zei:
I think this is the same tree as already was registered here.

TheTreeRegisterOwenJohnson, op 2014-08-31 19:31:36, zei:
Possibly Alnus x spaethii (japonica x subcordata)? In England, Alnus japonica is an asymmetrical tree, seldom thriving, with notably slender leaves and a square-cracked bark. The hybrid is straight-trunked, very vigorous and leafy, with more ovate leaves, and has a vertically ridged bark, as in the photo.

Conifers, op 2014-08-31 13:57:48, zei:
Too many leaflets for Juglans regia, and the terminal leaflet is not larger than the others. I suspect this is one of the hybrid walnuts, perhaps between Juglans regia and Juglans nigra, or between Juglans regia and Juglans ailantifolia.
TheTreeRegisterOwenJohnson, op 2014-08-31 19:23:26, zei:
From the bark, I think it's J. x intermedia (nigra x regia). It's good to see such interesting rarities appearing on the site!

Wim Brinkerink, op 2014-08-30 11:18:49, zei:

Jij hebt deze boom gedetermineerd als Betula platyphylla. Als ik de schors bekijk ziet hij er meer uit als een ermanii. Dat komt ook overeen met de beschrijving die aan het begin van het gebied Japan is gegeven. Maar..ik ga hem niet zonder meer wijzigen zonder jouw mening.

Conifers, op 2014-08-31 13:53:32, zei:
I would agree with Betula platyphylla - the seed catkins (visible in the foliage photo) are slender and drooping, whereas on Betula ermannii they are stouter and erect.

TheTreeRegisterOwenJohnson, op 2014-08-31 19:20:02, zei:
I think Betula ermanii x pubescens. A lot of big 'Betula ermanii' in Britain are this hybrid - presumably open-pollinated seedlings raised in Europe. In this case, the bark of the trunk is nearly B. pubescens, that of the smaller branches close to B. ermanii. The leaf is close to B. ermanii (but should show hairs on the stalk and under the veins). Fruit will show intermediate features. Betula [pendula subsp.] mandshurica/B. platyphylla in my experience has long-pointed triangular leaves which are a very dark (not yellowish-) green and forms a slender, sometimes slightly weeping tree.

Conifers, op 2014-08-31 13:55:25, zei:
A pear Pyrus sp. Sorry, not sure which species.
TheTreeRegisterOwenJohnson, op 2014-08-31 19:14:21, zei:
I think Malus yunnanensis. The bark is right (peeling in big scales of grey and brown). The fruit should have little raised white dots (not visible in the picture) and the leaf should be densely hairy underneath.

Hallo Leo,

Ik heb geworsteld met de bomen in het Zuiderpark in Den Haag. Jij hebt o.m. er een aantal Japanse elzen geplaatst. Ik weet niet of ik in de aanpassingen er helemaal ben uitgekomen, maar we kunnen van alles verbeteren. Ik zag in jouw boek dat je melding maakte van de originele Japanse els die in het Arboretum zou staan. Misschien, zo meldde je was de boom die jij benoemde wel een hybride.

Intrigerend en leuk. Ik heb je in eerste instantie gevolgd en geprobeerd aan te vullen en van foto's te voorzien. Toen ik klaars was en mijn foto's bekeek, zag ik dat ter plekke een els me in het Japan-deel had geïntrigeerd. Misschien, zo denk ik, is dat wel de echte Japanse els. Ik zal hem posten als niet gedetermineerde boom.

Ter verduidelijking. Ziet er oud uit. Is kronkelig , is onmiskenbaar een els en staat in het Japanse deel.

Wie weet.?

I wonder (from the bark colour and apparent needle length) if it might be Pinus strobus instead? But I'm unfamiliar with the behaviour of either species in Germany and would welcome other opinions. In Britain, P. strobus never carries that many cones.

Hi Tim, I just discovered possibilities for discussion. I strive for registering trees regularly, but probably from September to June I have to focus on studying at the University, hopefully I will find some moments to send photos of great trees. All in all, I would like to say that in Poland about 1/3 of great plants grows on private ownerships, usually old manor houses and it is really hard to talk to the owners and measure the trees, because You discern only tall fence and hear a vicious dog. Apart from difficulties tree chasing is a great, magnificent form of leisure.

However I am fully happy that around the world I can see people who love trees so much, thanks for these facilities.

ich hab ihn ja schon in der wohnung und im sommer auf der terrasse im topf mit so einer mischung sieben jahre lang grossgezogen.....

Ik lees dit verhaal nu pas (geen automatische mail ontvangen helaas). Het zal dan inderdaad wel een Thuja Plicata zijn. Wel jammer dan van het mooie verhaal op de site en het bord in de tuin. Dat klopt dus nu niet meer. Ik denk dat we deze personen op de hoogte moeten brengen.

Overigens de boom oogt wel vrij "geel" voor een Plicata. Kan het misschien een Plicata "Zebrina" zijn? Heb je nog een detailfoto van het loof?

Wim Brinkerink, op 2014-08-14 08:30:15, zei:
Hallo Nardo,

Ik heb de enige detailfoto van het loof die ik heb bij de boom geplaatst. Ik heb helaas een hoop foto's moeten weggooien, omdat een paar flinke instellingsfouten had gemaakt met mijn nieuwe camera. Helaas veel mooie foto's en detailfoto's kwijt geraakt. Ik neem aan dat Conifers en/of Martin indien nodig inhoudelijk op jouw opmerking reageren. Ik heb er niet zo veel verstand van.

Overigens was het bordje wel recent vernieuwd. Wellicht door de gemeente. Ik zal het toevoegen aan de boom.



Martin Tijdgat, op 2014-08-14 09:50:33, zei:
Nardo, Wim, Conifers,

This a bit yellow for Thuja plicata, but it is not cv. Zebrina. That is yellow and green stripped. Have a detailed picture from tree and twig of Th. pl. Zebrina from woodstock Gardens, Instioge, Ireland.


Conifers, op 2014-08-14 19:28:42, zei:
Agree, it is not 'Zebrina', which (like the animal it is named after) has striped variegation. The yellowing could easily be due to the soil conditions it is growing it. Shame about the new board, they will have to change it yet again when Wim tells them about its identity ;-)

Martin Tijdgat, op 2014-07-25 21:47:23, zei:

Kan het zijn dat dit de cv. Serotina de Selys is? Het opgaande karakter lijkt sterk op de Selysen die in Amstelveen staan op de Lindenlaan (Montesorrischoolplein)

Leo Goudzwaard, op 2014-07-26 05:37:00, zei:
Dat zou goed kunnen. Er staat ook een groot exemplaar van op de parkeerplaats van Arboretum Kalmthout, zie foto en beschrijving van deze cv in mijn boek Loofbomen in NL en VL. De bladvorm op de foto van Maarten klopt ook.
Maarten Windemuller, op 2014-07-26 14:40:08, zei:
Leo, Martin; thanks for suggestion. I uploaded another foto with detail of twig and leave. I will change the name if you are sure. What I found on Internet pictures it is the form that is making the clear difference between this subspecies and other subspecies of x canadensis. Are there other differences?
Martin Tijdgat, op 2014-07-26 20:28:13, zei:

Je zegt het; de vorm is zo duidelijk afwijkend en kenmerkend voor Serotina de Selys. Jongere exemplaren kunnen oppervlakkig worden verward met Italiaanse populieren. Maar ronde wortelaanzetten, ronde stammen en takken en de bast zijn zo afwijkend. Zie boek Leo voor detailkenmerken twijg en blad.

Maarten Windemuller, op 2014-07-26 21:49:36, zei:
Martin, ik heb wat oude foto's en ansichtkaarten opgezocht uit die omgeving, stuur ik je strks per mail toe.
Nardo Kaandorp, op 2014-08-14 11:15:05, zei:
Schitterende boom, maar ik ben niet overtuigd dat het een Serotina de Selys is. Deze boom lijkt niet op de boom die ik vorig jaar in Maastricht ontdekte. Zie Canadese populier (Populus × canadensis) '13617' (blijft jammer dat je niet op cultivars kunt zoeken op MT)

De stam van de boom in Maastricht is helemaal rond met diepe schorsplaten. De eerste takken beginnen pas hoog aan de stam. Misschien dat ik nog een foto heb van het blad.

Martin Tijdgat, op 2014-08-14 12:00:06, zei:
Nardo en andere MT-ers,

Zal de foto's van de Selysen van de Montesorri-school aan de Lindenlaan in Amstelveen nog in MT zetten. Dan zie je duidelijk meer overeenkomsten met deze Zweedse boom.. Daar langs de Lindenlaan staan meer bijzondere populierenklonen uit ongeveer 1960, waaronder ook de cv Serotina. Verschillen in schorspatronen willen in andere klimaten of op andere grondsoorten nog wel eens variëren.

Maarten Windemuller, op 2014-08-14 12:12:53, zei:
Information of the community Stängnäs: The tree was planted in 1938. There is not registered any subspecies of P.x canadensis.
Nardo Kaandorp, op 2014-08-14 18:54:01, zei:
Ik heb nog een paar (onscherpe) foto's van het blad gevonden van de boom in Maastricht. Toch wel een paar verschillen te zien. De onderkant van het blad is rechter en het blad loopt niet uit in een puntje. Ik ben benieuwd naar die bomen in Amstelveen.

Wim Brinkerink, op 2014-08-14 15:32:03, zei:
Hallo Small65 Ik was deze week in 's Graveland. Ik heb ook dit rijtje moerascipressen gezien en gemeten. Mijn bevindingen kloppen niet met de jouwe. Ik meen ongeveer 10 bomen gezien te hebben en ik heb één boom gemeten. Deze mat 341 cm op 1,30. Ik weet het niet meer zeker, maar ik geloof dat het de derde in de rij was. Ik heb hem wel afzonderlijk gefotografeerd. Ik heb ook het rijtje gefotografeerd. Ik zal de foto's even voorlopig aan jouw boom toevoegen zodat je ze kunt zien.Ik kan slecht uit de voeten met jouw meting van 303 cm. Kan dat fout zijn? Of kun je de dikste gemist hebben? Voorlopig voer ik de foto's even op en we spreken elkaar later.

Hallo Leute

Falls es einen Oberösterreicher, Salzburger oder reiselustigen Bayern hier gibt, wäre ein Ausflug an den Mondsee zu empfehlen, wo auf exakt 47.814988, 13.400745 ein großer Alter BMB der Entdeckung harrt. Ich habe Photos davon gesehen aber es ist mir ein bisserl zu weit heuer.

liebe Grüße

Hello Tim,

I wanted to upload this picture for Boughton Park (the site) rather than for this individual tree, but that function does not seem to be working at the moment?


Tim, op 2014-08-11 05:57:04, zei:
Hi Owen,

thanks for letting me know. I'll have a look soon when I have some time for this. In the meantime I have relinked this photo for you to Boughton Park (general location).

Wim Brinkerink, op 2014-08-02 13:29:16, zei:
Als je deze foto uit 2014 vergelijkt met die uit 2012 van Jeroen Philiponna en 2010 van Leo Goudzwaard, zie je dat er een flinke tak uit de kruin is gebroken. Volgens de pachter van de boerderij ernaast is dat in het voorjaar van 2014 gebeurd. Een deel ligt naast de boom. Het lijkt me dat dat niet het gehele uitgebroken deel is.
WiPe, op 2014-08-04 18:24:23, zei:
Dat takken uitbreken is op zich geen probleem. Integendeel zelfs, het hoort bij de normale groei van de boom. Doordat takken uitbreken kan de boom zich verjongen, geraakt hij van het overgewicht in de kruin af en kan hij hol worden, waardoor hij minder zwaar en sterker wordt.

Look at the big horizontal limbs of this oak tree. We have several of these trees with such limb growth orientations.

ssnjoff, op 2014-08-04 06:50:33, zei:
I do not know much about the trees in general but this one I adore. It is isolated and only visited by tourists in summer.

So I come to visit it more often when not the season.

The limb on the left is even longer but my lens were not wide enough btw...

Frank, op 2014-08-01 12:36:53, zei:
Hallo Wim,

ik denk dat is geen Sequoiadendron maar een Sequoia. En bij deze dikte zou de boom uit de jaren 185x kunnen zijn.

Groeten uit Duitsland,


Conifers, op 2014-08-01 16:54:59, zei:
Agree, it is Sequoia sempervirens
Wim Brinkerink, op 2014-08-01 18:52:50, zei:
Thank you both, I've changed the species.
Jeroen Philippona, op 2014-08-02 08:33:34, zei:
Hi Wim,

About the girth-measurement: indeed we propose to measure at 1.30 m above the centre of the tree, for some countries (the UK and Belgium at least) at 1.50 m above the centre / the medium level of the gound around the trunk. This method is also advised by the Native Tree Society of the USA, wich is among the most experienced groups in measurement of big trees. You measured this tree at 1.00 m above the high point around the tree. That could be a good alternative when it it is difficult to decide what is the medium level.

Measuring from the low point around the trunk is not advisable, in big trees the vertical difference between low and high point can be more than 2 meters, in that case 1.3 m above the low point is not possible to measure.

Several groups (for example the Tree Register of the British Isles) measure (at 1.3 or 1.5 m) above the high point, but for trees on a slope this often does not do justice to a heavy trunk below the high point, so that they have a disadvantage compared to trees on level ground.

beste Ive,

deze boom hoort nog niet thuis op MT. Er zijn vast wel oudere en mooiere bomen in je omgeving te vinden.

start58now, op 2014-07-29 20:59:58, zei:
Look at much growth is at the one side of the tree - or so it seems.

G Huber

Wim Brinkerink, op 2014-07-30 12:20:34, zei:
Yes the tree has bended sidewards. There are some big Holm Oaks next to it, so the tree bended to the direction where there is more room.
start58now, op 2014-07-30 12:25:38, zei:
But the extreme growth to the one side is very unusual - I wonder if the tree did lose some significant branches at its right.

No matter - it is a great tree.
