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?

Rayn, en 2014-07-13 06:57:39, ha dicho:
Without knowledge about cultivars, but I bet it's hard to find larger fruit in june in Sweden... Maybe in august/september?
Martin Tijdgat, en 2014-07-13 07:23:40, ha dicho:
Maarten, Conifers and Rayn,

This Malus-cultivar looks to be M. 'Hopa', if I compare the color and shape of the fruits.

Thanks for the comments. The shield at the tree might be a 'student joke' or some mistake which has not yet been noted. I'll contact the management of the garden if they are sure about the name.
Conifers, en 2014-07-23 20:13:31, ha dicho:
Hi Maarten - thanks for the extra info on this! Interestingly (for my comment above) Malus 'Niedzwetzkyana' is one of the parents of Malus × purpurea (so I wasn't so far out, either! ;-)

According to W J Bean, 'Niedzwetzkyana' is not much grown now due to its susceptibility to apple scab disease.

Hei Conifers, Thank you too, pleasure to find out things, LifeLongLearning.

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, en 2014-07-23 22:03:10, modificado en 2014-07-23 22:04:25, ha dicho:
Conifers,

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, en 2014-07-23 22:17:54, ha dicho:
Thanks, that's true, it's not a clone. I changed name. New problem: I cannot get a small "f" before tortuoso. The system automatically generates a capital F. Will ask Tim to change it. But what must we think about the oak, MT nr. 18706? :)

Hallo Maarten,

In eerste instantie dacht ik het zelfde, maar ik ben de rivier op die plek een flink stuk langs gefietst. Er staat geen andere monumentale boom, dus hij moet het wel zijn. (Ik kan het artikel overigens niet meer terugvinden)

Hi allen,

Ik wil jullie graag deelgenoot maken van een leuke ervaring. Een kennis van me, directeur bij de Tu Delft, heeft recent mij met mijn werk voor monumentale bomen, met name voor monumentaltrees en voor de Bomenstichting, voorgedragen als kandidaat voor de monumentenprijs Wassenaar 2014. Inmiddels heb ik een uitslag van de werkgroep die advies uitbrengt aan B&W. Ik ben genomineerd (als één van de drie). Binnenkort ga ik met wat mensen langs plekjes en bomen die ik ihkv monumentale bomen belangrijk vindt. Er zal hier uiteraard in de pers aandacht aan worden besteed. Op monumentendag (2e weekend van september) wordt de winnaar bekend gemaakt. Of ik nou win of niet ,maakt me niet zo veel uit. Wel vind ik het leuk om monumentale bomen onder de aandacht te brengen van een groot publiek. Jullie horen nog van me.

Der Baum 16510 steht teilweise auf meinem Privatgründstück. Ich finde es irgendwie eigenartig, dass dieser Baum am 10. Februar fotogfiert wird und ich wenig später eine Aufforderung von der Straßenmeisterei erhalte, dass der Baum möglicherweise umgeschnitten gehört. Da könnte man fast meinen, es will jemand den Baum kaufen. Schreckt die menschliche Gier vor nichts mehr zurück. In China werden solche Bäume geschützt, da man denkt, es wohnten die Ahnen darin. Das Holz dieses Baumes ist ziemlich viel wert. Ironie: Ich soll das Umschneiden dieses Naturdenkmals bezahlen!!!

Kann man nur hoffen, dass die Geschäftemacher die Seelen der gefällten Bäume bis in ihre Träume verfolgen.Ich bin empört! Danke auf alle Fälle für die tollen Fotos.

elisa45at, en 2014-03-16 13:07:09, ha dicho:
Hallo Alejchem,

leider ist das nicht so. Es wird behauptet, der Baum gehört zu zwei Drittel mir, das restliche Drittel der Straße, also dem Land Niederösterreich.

Ich danke dir jedenfalls recht herzlich für das Foto und hoffe, der Baum ist noch zu retten.

Mir wäre am leibsten, dass der Parkplatz gesperrt wird und der Wanderweg 7, bis Klarheit geschaffen ist, was mit dem Baum weiter passiert. Wenn ihr Zeit habt kommt morgen 17.3. um 11 Uhr zum Baum, da gibt es eine Besprechung mit Straßenmeisterei und Oberförster. Ihr könnt das alles gerne hier mit Fotos dokumentieren. Der Baum soll gestutz werden, da gehören aus meiner Sicht ein Landschaftsplaner und Baumdoktor her, nicht ein Straßenmeister. Da der Baum zwei Drittel mir gehört, verbiete ich einfach ihn umzuschneiden, basta, und vor allem ihn irgendwie zurecht zu stutzen. Danke, dass du dich gleich gemeldet hast.

Ich versuche jetzt die Republik wegen Verstoß gegen das Naturschutzgesetz § 5 zu klagen. Der Baum war als Naturdenkmal geschützt und er wurde plötzlich von heute auf morgen zum Nicht-Naturdenkmal erklärt. Ich farge mich, wei das bei einem solchen Baum geht.

Damit zeigt die republik, dass sie vom Aussterben bedrohte Arten nicht schützt, da sie sie nicht pflegt, wie es notwendig wäre.

Dafür bekommt sie ja von der Eu Fördergeld.

Ich schätze Mal, daß da die gleichen Brucker Hansln verantwortlich sind, wie beim Aukönig und bei den Leitha-Auen-Abholzungen. Von der Größe her schätz ich Mal, daß er so 120-150 Jahre alt sein wird und eine der letzten gesunden Schwarzpappeln. Wozu also das ganze dienen soll, nur weil ein paar Deppen hinten gezündelt haben, fällt so ein Baum nicht wirklich um.
elisa45at, en 2014-03-18 07:39:44, ha dicho:
Laut Aussagen der Straßenmeisterei stellt der Baum ein Gefahr dar.

Ich bin mir da nicht so sicher. Hast du Erfahrungswerte mit alten Bäumen? Was sagst du zu dem Fall? Du hast den Baum ja gesehen.

Er ist unten am Stamm schon ziemkich düeftig, aber schließlich wird ein Baum ja auch von Wurzeln gehalten und oben ist er ziemlich grün.

Hi Nardo,

Volgens mij heb jij deze bomen gepost. Volgens mijn informatie is het echter geen grondgebied van Schin op Geul maar van Valkenburg. Dat maak ik in ieder geval op uit Wikipedia en het staat ook aangegeven in deel zuid van de "Gids voor de Nederlandse tuin- en landschapsarchitectuur. " Ben je het eens en zoja vind je het goed dat ik het verander of wil dat zelf doen. Het lijkt me ook goed om het gebied van het kasteel wat preciezer te splitsen. De Thuja staat formeel op een deel van het kasteelpark, genoemd Sjloensheim. (Formeel adres; Oud Valkenburg 1)De molen en het heempark vormen één geheel en dat bestaat sinds 1950. Het wordt gerund door vrijwilligers van het IVN


Conifers, en 2014-07-19 21:45:27, ha dicho:
Hi Nardo, Wim - on the subject of the Thuja, I am still pretty sure this is T. plicata, and not T. occidentalis as the sign says. Can either of you get some close-up photos of the foliage and cones for verification?

Wim Brinkerink, en 2014-07-20 08:22:53, ha dicho:

Ich bin ein bisschen dem Ausschlussverfahren gefolgt.

Für eine Waldkiefer hat der Baum eine viel zu dunkle Rinde. Die ist ja bei Pinus sylvestris eher rötlich.

Außerdem sind, meiner Ansicht nach die Triebe von P. sylvestris etwas zierlicher als bei P. nigra.

Ich ich da kein Experte wie Conifers. Es hätte natürlich auch eine andere Kiefer sein können.

Aber Waldkiefer konnte ich definitiv ausschließen und Schwarzkiefer war das naheliegendste.

From the branch structire, it looks intermediate, so it might be Larix × marschlinsii (the hybrid between European and Japanese), but that is not certain.

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, en 2014-07-04 19:12:04, ha dicho:
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, en 2014-07-04 19:28:08, ha dicho:
Thanks, Sisley!

I proposed in the case of the Oak of Ivenack (roble común (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, en 2014-07-04 19:57:20, ha dicho:
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, en 2014-07-04 20:21:16, modificado en 2014-07-04 20:22:06, ha dicho:
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, en 2014-07-04 20:52:39, ha dicho:
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, en 2014-07-04 22:29:30, ha dicho:
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, en 2014-07-05 06:33:59, ha dicho:
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, en 2014-07-05 19:38:55, ha dicho:
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, en 2014-07-05 22:13:50, ha dicho:
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, en 2014-07-06 08:30:53, ha dicho:
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, en 2014-07-06 10:51:02, ha dicho:
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, en 2014-07-06 15:06:54, modificado en 2014-07-06 15:08:41, ha dicho:
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, en 2014-07-07 09:25:34, ha dicho:
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, en 2014-07-07 11:50:59, ha dicho:
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, en 2014-07-08 07:44:11, ha dicho:
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, en 2014-07-08 17:09:19, ha dicho:
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?

Hello RedRob,

as you certainly noticed by now, we have conflicting readings. From the record sequoias in Benmore and along the Big Trees Walk Uig I miss individual photos. It seems unclear to me whether these trees can be identified on site at all. Under these circumstances, no one will take the long journey to go there and to confirm the measurements. Even from the highest Douglas firs in UK I can not find individual photos.


RedRob, en 2014-07-17 16:27:13, ha dicho:
Hello Karlheinz, the Sequioadendrons at Benmore were visited and re-measured a couple of months ago by David Alderman and Chic Henderson with matching Forestry Pro lasers. The Uig tree was 56.4 metres, 498cm girth, there is a photo of this tree on the TROBI site. The tree in the avenue at Benmore was 56.4 metres to the top, which was dead, 54 metres to the highest live part of the tree, 602 cm girth. The Sequoiadendron at Blair Atholl, Diana's Grove could be the tallest of all as it was 54.50 metres in 2007 with a long wispy spire tip. I believe that Chic Henderson will be visiting this at some point as he is systematically re-measuring the trees across Scotland (about to check a reputed 30 metre Juglans Regia measurement) Chic said that he might join MT so may post some photos.

Which Douglas Firs do you want photos of Karlheinz, the Reelig Glen tree and others are on here already?

Hello RedRob,

a photo from Benmore trees shows the "Avenue of Giant Redwoods." I can not identify the specific tree '1715' with the record size of 56.40 m. How can I find this particular tree? I mean, if a record tree is reported on MT, it should be described so accurately that it clearly can be located in the field without further Internet research.

The highest Douglas-fir in the UK is still the '15298 'in Reelig Glen with 66,40 m. The only photo on MT shows a group of trees. There is no photo, e.g. from the base of the trunk, that uniquely could identify this particular tree. The photo of the second highest Douglas-fir '15299' in Reelig Glen shows the same group of trees and again no individual picture of this tree. From the third highest Douglas-fir '15562' there not any photo is shown. When I am in Reelig Glen, how can I detect which is the respectively measured tree?

Een van de oerbomen die niet gekapt zijn door de kolonisten van Madeira (sinds 1420). Het betreft een stinklaurier. Prachtig gebied met vele oude bomen van het oorspronkelijke laurierwoud (Laurissilva) van Madeira. Vroeger was bijna het gehele eiland bedekt met verschillende laurierbomen met mossen en epifyten begroeid. Ongeveer 15-40 miljoen jaar geleden was bijna heel Zuid-Europa bedekt door laurierbos maar door de ijstijden zijn veel laurierbossen verdwenen. Bijna al het oorspronkelijke woud van Madeira is gekapt maar er staan wonderbaarlijk genoeg nog vele exemplaren op de hoogvlakte Paul da Serra waar vee tussen graast. Sommige bomen zijn gelukkig beschermd door gaas. Het is dus een relict van het vroegere oorspronkelijke oerbos van het eiland maar ook van miljoenen jaren terug!

Dit gebied staat op de UNESCO werelderfgoed lijst. Hierbij de omschrijving van het gebied op de website van UNESCO:

"The Laurisilva of Madeira is an outstanding relict of a previously widespread laurel forest type. It is the largest surviving area of laurel forest and is believed to be 90% primary forest. It contains a unique suite of plants and animals, including many endemic species such as the Madeiran long-toed pigeon."

Floriduscampus,

Bewerk eerst je foto's tot licht, compositie en kleur zo natuurlijk mogelijk zijn. Gelukt? Je kan dan de pagina van deze boom openen en vervolgen met "Upload foto's" zoveel foto's toevoegen die aan de info van deze boom wat toevoegen. Zijn andere bomen van deze groep apart de moeite waard, voeg ze dan als nieuwe boom toe. Enzovoort.

Zelf probeer ik altijd een foto bij te voegen die de boom van top tot teen laat zien, maar ook de kroonopbouw en bast van de boom. Liefst voeg ik een foto toe die twijg, blad en bloem of vrucht laat zien. Beide foto's geven vaak alle info die nodig is om de determinatie van de boom te verbeteren, als er twijfel over is. En wie twijfelt er af en toe niet over de correcte naamgeving van bomen.

Veel plezier op MT!

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, en 2014-07-10 14:02:04, ha dicho:
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.

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.

Auf Seite 2 die Nummer 1: https://www.uni-hohenheim.de/fileadmin/uni_hohenheim/Intranet_MA/Zentrales_Marketing/Broschueren/Hohenheimer_Gaerten/Baumveteranen_Schmuckgehoelze_2013.pdf

Die Blätter sind tatsächlich sehr tief gelappt, was eher für Liriodendron chinense sprechen würde. Ich Frage mal Conifers, was er dazu meint.

Viele Grüße,

Rainer


Conifers, en 2014-07-07 20:22:00, ha dicho:
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, en 2014-07-08 16:46:38, ha dicho:
Hallo Conifers,

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

Danke und viele Grüße,

Rainer

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?

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.

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'.

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.

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.

Hello Owen, definitely worth visiting Loch Ken to measure these trees, they looked quite impressive in the Geograph photos but are more impressive in reality. The line with the 56 metre are along the road on the Loch side which makes them look even more impressive. Quite a tight angle to measure up as little room to get back so I may not have it that top and some of the trees could be abit taller still but I don't think any will be 60 metres yet.

I'd doubt it is 'Laciniatum Wieri' - the leaves are within the normal range of variation in the species, and this is not a grafted specimen (no graft line visible in the trunk photo), so it is unlikely to be a named cultivar.

Additionally, according to W J Bean, 'Wieri' (so named there, not 'Laciniatum Wieri') has pendulous branches (I'm not certain if this could be a different cultivar to 'Laciniatum Wieri' though).


Martin Tijdgat, en 2014-06-25 09:46:32, ha dicho:
Conifers,

Wieri is a synonym of Laciniatum Wieri. Acer sacch. and the cultivar form both big trees with wide spreading branches. The leafs of the cultivar are more stretched out and finer lobbed, that is why I came to this determination. I have both trees in my care as local tree officer.

Thanks! I checked a couple of other books (Rushforth Trees of Britain and Europe, and the New RHS Dictionary of Gardening), and both give 'Wieri' as the cultivar name; Rushforth cites it as a cultivar within the botanical forma laciniatum. Both again emphasized the pendulous branches as a key character of 'Wieri', which this tree does not show.

Conifers, en 2014-06-27 21:02:44, ha dicho:
Hallo Rainer,

As I mentioned above, this isn't 'Wieri'; it is just a normal Acer saccharinum, with no cultivar name to be applied. It is not a grafted tree, as there is no graft line; maple cultivars are always grafted as they can't be rooted from cuttings.

Er is een hele groep Liriodendrons aanwezig. Enkelen zijn, wellicht door bliksem getroffen of door stormen beschadigd, gereduceerd tot levende stompen van een meter of 4 hoog. In de directe omgeving vormt zich een heel bosje met zaailingen van diverse leeftijden. Deze zijn de natuurlijke verjonging voor de oude verdwijnende exemplaren.

A break from Glenlee. Couldn't get near enough to 100% identify this group but could clearly see the base of the tallest with the laser. This is group is the tallest group that I saw driving all around Kielder, a forestry worker I met earlier said that trees are only left to grow to this size in public areas like this so these are almost certainly the tallest in Kielder I would say and he thought. The massive majority of trees in Kielder are Sitka, measured many as I went around. I took these as older, rounder headed Sitka Spruce, the base that I could see did look Sitkaish but I am not sure enough. An ident is needed?

Conifers, en 2014-06-27 21:04:54, ha dicho:
Hi Rob,

Which tree do you mean? I'm seeing Picea sitchensis, Picea abies, and Pseudotsuga menziesii, all mixed in these photos.

Hello Conifers, absolutely spot on with the location marker, exact tree, excellent judgement. They are Douglas Fir, wasn't 100% sure as everything was Sitka and didn't see another Douglas stand anywhere in the forest. Thought that they might be mature flatter topped Sitka but Douglas they are. The 41 metre Sitka looks like the County Champion for Northumberland, didn't see or measure any taller from a huge choice.

There are - or maybe were - some taller Sitka Spruce in Kyloe, 45-50+ metres tall, but I fear the tallest were cut a couple of years ago.

Hello all

Yes it is growing in absolutely darkness, by a constantly high humidity and temperatur of 10° C (365 days the Year). Only when groups of people come this way, the electriic light goes on for that time, til the last one is 20 meter away. There are no insects inside the cave only bats who brought the seeds inside.

I think, in that way it need thousends of years to become a real big tree, but it is now also a rare monument of a different kind.

It looks indeed like a Quercus robur, but Quercus petraea = "oak of the rocks" could also be translated as "Steineiche". The leaves indeed look like those of a Pedunculate Oak = Stieleiche and do not look at all as a Sessile Oak - Traubeneiche, but perhaps you have made a photo of them, Rainer?

If you look at the other pictures of this oak tree you will see that it is the tree in the back. But the lines and colors of this picture took me in as a beautiful photograph

Alberto Cuervo Flores, en 2014-06-25 09:38:19, ha dicho:
The oak is at the bottom of the photograph, sorry if poorly done, as I do in this case? upload the picture as a group of trees? I liked the photo and oak leaves as they carried her to the bottom. The pine is pinus pinaster think.
Conifers, en 2014-06-25 10:32:41, ha dicho:
Thanks! One option would be to register the pine as a MT specimen as well, and transfer this photo to that.

I wondered about P. pinaster, as the foliage looks OK for it, but the bark (fairly smooth, not deeply fissured and plated) is more like P. halepensis. Can you get a close-up of the foliage and cones?

Alberto Cuervo Flores, en 2014-06-25 11:10:21, ha dicho:
Thanks Conifers, another day that passes there will try to take pictures of the foreground. But I think that pine is not very big.

Here are many naturalized pinaster pine centuries. Radiata there are also many more recent afforestation for its fast growth and good wood for paper and chipboard. The Aleppo pine I think he likes more heat and dry weather. In the UK there halepensis naturalized?

Dag Tim,

Ik las dat je de leeftijd van de plataan po het Prudens Van Duyseplein in Gent, wist te determineren op 314 jaar. Mag ik vragen wat jouw bron is voor die info ?

Ik ken die boom al sinds lang, en ben daar, omwille van een verhaal, wat research naar aan het doen.

Het zou handig zijn mocht je zin hebben daar wat feedback rond te geven ?

Alvast mijn beste dank,

Hallo Paul,

ik heb het plantjaar eens gelezen in een artikel over deze boom in "Het Civielke", het regelmatig verschijnend ledenboekje van VTK, de studentenvereniging van de burgerlijk ingenieurs te Gent, alwaar ik zelf ook gestudeerd heb.

Geen idee wat hun bron was. Het boekje moet zo'n jaar of 5 à 6 geleden verschenen zijn.

Groeten,

silentoak, en 2014-06-25 05:00:26, ha dicho:
Dag Tim,

Ik ben gisteren de boom nog eens gaan opmeten ( plataan Prudens van Duyseplein ).

Een diameter van 130 ( W/O) en 150 (N/Z). Omtrek 417cm.

Indien we de minder betrouwbare methode nemen van de regel in diktegroei, denk ik dat voor deze plataan 1cm per jaar

( zanderige ondergrond, op een heuvel en in de stad ) niet zo fout is.

Dit is wat ik vond op onroerend erfgoed:

"Het vroegere zogenaamde gebied "Eekhout" dat sedert de 19e eeuw een concentratie van arbeiderswoningen kende, werd gesaneerd in de jaren 1880, na de afbraak van de Bataviawijk.

In 1883 wordt het Prudens Van Duyseplein aangelegd in een interessant stedenbouwkundig geheel op radiaalstructuur: de talrijke gelijktijdig getrokken straten convergeren in het licht glooiende pleintje, ingeplant op een helling, met in het midden een rond grasperk met een plataan. Interessante oplossing voor de omzomende huizen met cirkelvormige inplanting.

Variërende huizentypes uit het laatste kwart van de 19de eeuw met verschillende materialen en verhoudingen. Tot onlangs ten zuiden homogene huizenrij, voornamelijk hoekhuizen, met bepleisterde en beschilderde lijstgevels van drie bouwlagen. Verder vrij gewone baksteenarchitectuur uit eind 19de eeuw, afgewisseld met eenvoudige lijstgeveltjes van het doorsneetype."

Ik zocht ook nog op oude kaarten, uit 1700 en vond er wel bomen op die plek op terug. maar vermoed dat dat fruitbomen zullen geweest zijn.

Ik hoop u hiermee geholpen te hebben.

Mvg

Thanks Frank, my pictures are always pure, no photoshopping. It is the hard light in summer at 16pm, I like it when you can see the natural circumstances in a photo. The light would have been much more colourful at 18pm but not enough time to stay and wait. I also need someone at the stairs behind the tree, now it is too empty. I would encourage everyone to photograph people next to the trees.
