This isn't Malus sieversii - that is the direct ancestor of orchard apples, and has much larger fruit (see e.g. here).

Could be a Malus × purpurea cultivar. Maybe a case of labels swapped by vandals?

Without knowledge about cultivars, but I bet it's hard to find larger fruit in june in Sweden... Maybe in august/september?

Hei Kouta,

You mihgt be right. When I search the books and the Internet (f.i. USDA, Wiki sites orhttp://scholar.google.com) I see three variants: P. x petrowskiana, P. petrowskiana and P. "Petrowskiana" No doubt there will come more comments so we find the correct spelling. Then we ask Tim to change it, I cannot do it myself.

Yes, I use the Nikon 550 AS. This tree I measured from south-east side (A) and north side (B). Results A 31.60 + 1.40 =33.00 and B 32,40 + 1,80 = 34.20. Avarage = 33,60. A and B are the results of scanning the top a few times, not point & shoot, and more times pointing the foot of the tree.

Hei Kouta,

About the picture from 1990: I removed it and asked a member of the board of the Dendrologian Seura (DS) to discuss my question to use that foto here. I think you know DS is updating the register of giants for a new publication.

Best wishes, Maarten


KoutaR, am 2014-07-10 14:02:04, hat gesagt:
In my opinion, we could also accept P. x petrowskiana, but P. petrowskiana is clearly wrong as it is not a species. A reason for the name confusion is that Finnish/Russian 'Petrowskiana' and North American petrowskiana seem to be different taxa. Canadian studies have shown that taxa called P. 'Petrowskiana', P. 'Rasumowskiana' and P. x berolinensis have the same genetic composition and thus are synonyms; consequently they are not believed to be clones. However, these taxa in Finland are very distinct; even I can differentiate them. The Canadian studies have used Canadian material. Apparently the material has mixed when transported from Europe, maybe by early colonizers, who know. Finnish specialists have this opinion (Pentti Alanko said something like "when you see these taxa in other countries, you immediately see something is wrong"). In Finnland they are single clones, so 'Petrowskiana' would be the best in this case.

Good that you asked DS about the image. With who are you communicating? They recently visited the Netherlands and Belgium, did you meet them there?

Yes, I know they are updating the list.

Hello Treelovers,

I just found that this tree (no. 8457) has been removed from this site. Does this mean it doesn't exist anymore? Would be a real shame, since it seems to have sprung from seeds collected from the famous Grizzly Giant and belonged to the highest specimen in Europe. At least this is what I read here:http://www.treeblog.co.uk/viewtags.php?tag=Sequoiadendron_giganteum&p=1

Just curious to learn the reason for its removal...;-)

Don't believe anything you read in the Daily Fail - one of Britain's most notoriously inaccurate newspapers ;-)

Certainly an interesting tree, but 5,000 years is fanciful. It fails to take account of the simple point that growth rings become narrower as the tree ages.

Quote from the Daily Fail article: "and its ring count is 120 per inch which makes it [more than] 5,000 years old" - i.e., they've taken the outermost ring count and assumed it continued at that rate for the whole life of the tree. Typical muddle-headed journalists :-(

Sisley,

Was this tree really climbed on 2013-06-20 and is 57,7 m really achieved by tape drop? If I recall correctly, the height was first over 58 m and you corrected it after we said the height must be measured to the average ground level, not to the lowest ground level.


Sisley, am 2014-07-04 19:12:04, hat gesagt:
Yes he was achieved by tape drop by the team of climbers in june 2013.

My first measure was made by laser and she was wrong because the I taked the lowest point of the trunk base.


KoutaR, am 2014-07-04 19:28:08, hat gesagt:
Thanks, Sisley!

I proposed in the case of the Oak of Ivenack (Stieleiche (Quercus robur) '1758') that if a tree has been measured by a reliable method (tape or laser), height measurements made by an unreliable method should not be added.

It is an equivalent case with this tree. Tape measurement has been universally considered as the most accurate and reliable method. I propose that a laser-measurement should not be added if a former tape measurement proves that the laser-measurement is inaccurate like in this case. Or is the top broken?


Rainer Lippert, am 2014-07-04 19:57:20, hat gesagt:
Hallo Kouta und Sisley,

entscheidend bei Tape-Drop ist aber auch, wie genau der Nullpunkt unten gemessen wurde. Steht der Baum am Hang, kann das schon eine Differenz ausmachen, wenn man unten ohne genauem Messgerät den Nullpunkt bestimmt. Und auch oben können beim Tape-Drop noch Probleme auftreten, den tatsächlich höchsten Trieb zu erwischen. Karlheinz ist hier zweimal hochgeklettert:http://www.monumentaltrees.com/de/bericht/1027/

Beidemal hatten wir da die Probleme bei der Abtastung der Spitze. Also auch da kann es zu Fehlern kommen. Also nicht zwingend muss Tape-Drop die genaueste Messung darstellen. Das Equipment von Karlheinz, also TruPulse 200X auf Stativ zur Spitze und Basis, und Leica Disto D8 vom Stativ aus zur Nullpunktbestimmung, sehe ich schon als sehr genau an. Eventuell genauer als Tape-Drop, wo nicht bekannt ist, wie exakt der Nullpunkt unten bestimmt worden ist und wie sich oben die Spitzenabtastung gestaltete.

Viele Grüße,

Rainer


KoutaR, am 2014-07-04 20:21:16, geändert am 2014-07-04 20:22:06, hat gesagt:
Sisley, could you ask the measurers, how they defined the average ground level? Did they measure or estimate it? If estimated, that can really make an error, though likely not 1.4 m.

I believe it that Karlheinz had problems with measuring the top in tape measurement - one year ago he had no idea how to do that, until Michael Spraggon explained it to him.

The distance measuring of the 200X and Disto is undoubtely top-accurate, but the angle measurement not so. It may result in a ~50 cm error. We have already discussed this and the measurement gurus of NTS (Bob Leverett) have indirectly confirmed it.


Karlheinz, am 2014-07-04 20:52:39, hat gesagt:
The sequoias in Ribeauvillé and Niederbronn I measured about one to two meters less in height than my predecessors. That surprises me a lot. I have no explanation. The measurement conditions especially at the trees '12175 'and '8217' were good. I had a clear view simultaneously to the tree top and to a marker nearby the base. The measurement was performed with TruPulse 200X on tripod.

greetings, Karlheinz


Karlheinz, am 2014-07-04 22:29:30, hat gesagt:
Kouta, your statement about accuracy of angle measurement with TruPulse 200X and Leica Disto D8 I can not confirm. In my earlier tests both clinometers matched very accurate. The measurement accuracy of the TruPulse is rather limited by the width of the laser beam, which does not allow pinpoint accuracy aiming at small targets.

Sisley, where is your home location? Maybe we could once meet somewhere in the middle, and together measure a tall tree.

Karlheinz

KoutaR, am 2014-07-05 06:33:59, hat gesagt:
One possible explanation is that Pierron & Thomas have measured the tree to the lowest ground level like Sisley did at the beginning. Sisley, what do you think about this? Is it a usual way in France to measure trees to the lowest ground level = "low slope point"?

Sisley, am 2014-07-05 19:38:55, hat gesagt:
Hi, all poeple !

I know that the climbers measure from the top to the middle slop point.

L.Pierron said me his method, and my first measure of the sequoia of Ribeauvillé was 58,10 m at the low trunk point.

If I subtract approximately 0,75 m to join the middle slop point we find 57,35 m.

For the mapple tree it maybe possible that the real tope was not targeted ? I know, it was not obvious to found him without the leaves, therefore with the top is more hidden.

The tallest Douglas of Ribeauvillé was measured by tape of drop, 60,5 m, I found 62 m(measure not changed in page)and I see, Karlheinz found 61,5 m. The difference is not very important.

And for the trees near Niederbronn, my results were not so good, it was the first measures with laser and I did'nt have take the middle slop point.

The more important point that I see for the mistakes, is that I don't have pattern surveyor to set against the trunk.

In many situations this object would have helped me.


Karlheinz, am 2014-07-05 22:13:50, hat gesagt:
Last year I was in Ribeauvillé just on the go with Nikon. I had no other measurement equipment here. I did not think the readings for accurate enough to be entered into the data field for measurement. Only at the tallest Douglas of Ribeauvillé I brought a height value in the caption of the photo.

This year, I've come back, have brought my entire equipment and have done my best in the measurement. For base-determination on the slope ground I used the Leica Disto D8. As difference between low and high slope point at the sequoia of Ribeauvillé I determined 1.40 m, not much different from Sisley.


KoutaR, am 2014-07-06 08:30:53, hat gesagt:
Without seeing the tree, I guess the difference is partly a consequence of different interpretations of the highest and lowest ground levels. On a steep slope it can make a big difference. And it is largely not up to used device but just interpretation.

In addition, the clinometer error of the 200X (max. +/-0.2° according to the user manual) may explain a part of the difference. Note that even if the device gives repeated the same angle, it does not mean the angle is correct. If my "one metre long" tape measure is too long, it gives repeated the same result but it is not correct.


Karlheinz, am 2014-07-06 10:51:02, hat gesagt:
Kouta, I know that you think your Nikon 550 for the best instrument in the world! And I guess, Sisley also measures with Nikon, is that right? In the manual of my Nikon 550 I find no specification for clinometer error. Do you really think a manufacturer that conceals the error tolerance of his unit, has the higher quality sensor? The readings with Nikon have a greater range of variation compared to Leica and TruPulse and they are more dependent on interpretation by the measurer.

The Nikon is for our purposes certainly a recommendable device. But we should not expect any accuracy that can not give the unit. The competition between European record trees which are only a few decimeters apart is hardly to decide with Nikon.


KoutaR, am 2014-07-06 15:06:54, geändert am 2014-07-06 15:08:41, hat gesagt:
It is very clear that all the TruPulses are more accurate than Nikon. I have never denied it. But here we were comparing 200X vs. tape. Everybody can do a bit trigonometry and calculate how big height error can -0.2° error at the base and a +0.2° error at the top (the worst case) make. One could think that if the distance measurement is centimetre precise, height measuring is centimetre precise, too. I also believed so at first - for example, I wrote "Disto gives accurate distances to the nearest centimetre, so using a reference point did not decrease the accuracy" in my report about the tallest beech (http://www.monumentaltrees.com/en/report/772/). But the clinometers of these devices are simply not accurate enough for that accuracy. Karlheinz, could it be time to accept that. In Finland much cited is a statement of a former president: "the beginning of all the wisdom is the confession of the facts". And I am not speaking for Nikon, which is, of course, less accurate and less reliable. I would buy 200X, too, if it was much less than 1000€. I am ready to give 2000€ for a good camera but measuring is simply not important enough for me and has recently become still less important due to this like disputes.

Karlheinz, am 2014-07-07 09:25:34, hat gesagt:
Tape drop as well as instrument measurements, both can be accurate or inaccurate. That depends very much on the care is measured by, how favorable are the measuring conditions in the individual case, and how accurate are the measuring devices. I can not say from the outset that a particular measurement method always results in the most accurate value. If all conditions are optimal, I would prefer the tape-drop measurement result to a Trupulse 200X measurement, presumed when tape drop it is possible to determine the residual height to treetop safely.

For Koutas presumption of an influential inaccuracy of the 200X tilt sensor there is no confirmation, not even in the forums of the NTS (ent-bbs.org). In my estimation, the fault tolerance of the TruPulse 200X is not based on the tilt sensor, but on the wide laser beam when it impinges on inclined or uneven surfaces. Who wants to know more about how I judge the accuracy of my instruments, can read about it in my article in the Bulletin of ENTS, Volume 9, 2014 "Testing Three Different Range Finder With Built in inclinometer": http://www.nativetreesociety.org/bulletin/b9_1-2/B_ENTS_v09_01&02.pdf


KoutaR, am 2014-07-07 11:50:59, hat gesagt:
The source or "confirmation" for the tilt sensor accuracy/inaccuracy was the user manual. You once gave me this info yourself. Why I referred to the NTS forum was that you first claimed the tilt sensor error is always the same, thus the error at the treetop would counteract the error at the base. Then Bob said it implies to the mechanical clinometers only, and after that you stopped to claim that. Disto's tilt sensor accuracy is actually lower than that of 200X: -0.2°/+0.3° outside the room temperature, according to the user manual. You have not tested the tilt sensors yourself.

A wide beam is a further error source, indeed. (Yes, applies to Nikon, too.)

200X and Disto are great instruments without doubt, but they also have their limits. You once said the other measurers will hate you because you have better instruments. I don't think that is true. It is great that you have them and make accurate measurements. But it is strange that you sometimes make statements that are based on nothing being essentially "religious".


KoutaR, am 2014-07-08 07:44:11, hat gesagt:
I found the old email of Karlheinz. The tilt sensor error of 200X is +/- 0.1 degrees "typical". Only Leica's user manual tolds how much adds low or high temperature. So this was my mistake.

RedRob, am 2014-07-08 17:09:19, hat gesagt:
I thought that a 58 metre Sequoiadendron had been reported on here, a Scottish tree measurer called Chic Henderson recently measured the Sequoiadendron at Benmore as 56.4 metres which looked like the second tallest in Europe which I just couldn't re-find on here?

Hallo Rainer,

Thanks for the query! Unfortunately, leaf shape is not a reliable distinction between the two; both species are variable, with extensive overlap in shape. The only reliable difference is in the flowers, green with an orange spot on each tepal in L. tulipifera and all-green in L. chinense.

However, there is one other important point with this tree that gives us a safe conclusion: the planting date of 1779. L. chinense was only introduced to the West in 1901, so therefore this tree has to be L. tulipifera.


Rainer Lippert, am 2014-07-08 16:46:38, hat gesagt:
Hallo Conifers,

danke für die Antwort. Das mit dem Alter ist ein gutes Argument. Demnach handelt es sich zweifelsfrei um Liriodendron tulipifera.

Ik heb zelf een drietal giganteums opgekweekt uit zaad vorig jaar. In augustus zijn ze opgekomen.

Ze moeten alle drie een plek krijgen in mijn tuin dus wil er alles aan doen om ze te laten overleven. Ik was al heel erg blij dat de miniscule plantjes de winter zijn doorgekomen. De grootste is nu 21 cm. Hij groeit erg hard. Ik heb ze ook alle in volle zon staan. De zon heeft de afgelopen maanden relatief veel geschenen, ze kunnen er dus prima tegen lijkt het.

Ik zit met de vraag wanneer deze nu het beste definitief de grond in kan. Zou dat eind van deze zomer al kunnen of moet ik nog 1 of meerdere zomers wachten? Kan een winter nu funest zijn voor een 1 jaar oude boom?

Ik had ook al begrepen dat slakken er niert vies van zijn. Klopt dat, zijn deze een gevaar als de boompjes jong zijn. Vraag is dus wanneer ze definitief en veilig naar buiten kunnen. Wat is je advies?

Hei Martin,

Dank je. Fototechnisch gezien zijn dit lastige bomen. Weinig licht en ruimte, daarbij regende het ook. Met een FL van 24 mm en cropfactor 1.6 had ik hier 8 foto's nodig. Er staat nog een andere 'trollenbeuk' op dit terrein. Daar kan ik nog geen bruikbare foto van selecteren. Ten oosten van Lund is een Trollenbos, waar dit soort trollenbeuken van nature voorkomen. Die in dat bos zijn hoger en bij zonnig weer zijn de lichtomstandigheden beter. Zie ook http://de.wikipedia.org/wiki/S%C3%BCntel-Buche

Dear friends,

I've looked at different images of Quercus petreae 'Mespilifolia' and Q. rosacae, but I still think this is a 'Mespilifolia' due to the forms of leaf at the base; drooping along the leafstalk.

Hallo,

Das ist nicht die 'Mespilifolia'. Die echte 'Mespilifolia' hat fast alle Blätter ungelappt, aber viele Blätter dieses Baumes haben völlig normale Traubeneichenähnliche Form. NB: im Foto '32927' sind einige gelappte Blätter gefressen oder sonst in schlechtem Zustand und sehen deswegen ungelappt aus. Ich weiss nicht, ob es die Zurückkreuzung zwischen der 'Mespilifolia' und der normalen Traubeneiche gibt - ein Bisschen sowas sieht dieser Baum aus.

Dear friends,

Can it be that this is in fact a Quercus petraea cv. 'Mespilifolia', but with a lot of backlash to the original Q. petraea. I can't make out the distribution of mespilifolia-type leafs in comparison with the other leafs. We see this in more trees like Ulmus x hollandica 'Wredei' to 'Dampieri'.

Hallo Kouta und Martin,

heute habe ich zufällig in einem Park eine Quercus petraea 'Mespilifolia' mit 3 m Umfang gesehen. Zumindest laut Schild. Also die Blätter haben schon starke Ähnlichkeiten zu diesem Baum hier gezeigt.

Quercus pyrenaica is not native in the Netherlands and Belgium, but perhaps there are a few trees of this species in special arboreta.

Quercus pyrenaica no es nativo de los Países Bajos y Bélgica, pero tal vez hay algunos árboles de esta especie en arboretos especial.

Hi Jeroen,

Thank you very much for translating to the Spanish.

Yes, I think what the difference with Quercus robur is that pyrenaica needs dry season to develop correctly. In my house, in Galicia (Atlantic climate) I planted, Quercus ilex, faginea and pyrenaica, and i do not know if will grow well. (Although also influence soil) such faginea prefers calcareous soils. And in Galicia predominate siliceous soils.

Thanks and sorry for my english.

Alberto.

Hallo RedRob,

ja, speziell was es Douglasien angeht, ist der Ort für Deutschland außergewöhnlich. Karlheinz und ich waren schon in Emmendingen und Ebersbach, wo bis vor zehn Jahren noch der jeweils höchste Baum Deutschlands hergekommen ist, bevor es die Waldtraut in Freiburg wurde. Dort stehen nur einzelne Douglasien, und die kommen nur knapp über die 60 m. Und in Freiburg hat der komplette Bestand mehr als 60 m. Im März und auch dieses mal haben wir wohl noch so zehn Douglasien mit 62 oder 63 m gemessen gehabt. Aber die haben uns nicht weiter interessiert.

Ob Kouta derzeit unterwegs ist weiß ich nicht.

The largest of any Ulmus x hollandica 'Vegeta' is in Prospect Park, Brooklyn, New York, USA. It is bigger than any I have seen on the net, in the field or any historical text. I do believe the NY Parks have measured it, but as yet I still haven't got the statistics. It can be seen on Streetview along with some very fine Ulmus hybrids from east Anglia and possible Ulmus plotii too.

Ulmus americana also appears in Traralogan, Victoria, Australia and a huge tree can be found in Harrietville, NSW which may be Australia's largest. Generally however Ulmus americana is rare in Australia. There are several small trees in Canterbury County in New Zealand and in Canada some big trees can still be found in Winnipeg.
