Is die Turkse Hazelaar werkelijk 34 m hoog bij een omtrek van 1,18 m? Ten eerste een verbreking van het hoogterecord op MT met 9 meter en vervolgens bijkans de dunste boom van Nederland met deze hoogte! Zou mooi zijn als je er ook foto's van hebt.
oeps, het is 24 m Jeroen, is al een mooi NL record, Leo
Tiepfoutje dus, maar toch een respectabele hoogte voor de soort!
waarom zijn er eigenlijk monumentale oude mooie bomen onlangs gekapt in het park van arenberg?
om er een stomme parking te zetten.
dit alles zonder aankondiging en alles was geklaard in één dag. zéér verdacht. en vooral schandalig!!!
wie is de verantwoordelijke hiervoor?
as you know the colors of the map icons indicate the trees's girth.
I'm planning to add the possibility to choose what tree property is used for the color: not only girth, but also height, exact height, age, ...
Currently this is with a fixed legend (5-6m is orange, 6-9m is red, ...). This is still a relict from my old Belgium based giant sequoia site for which this legend made sense. For many other trees and other places this is not the case: all trees might be green or there might be too many dark red ones.
If I would add tree height, I could also take a fixed legend (e.g. 40-60m is orange, 60-80m red, ...). This might again be appropriate for some tree species and some areas, but not optimal for others.
That's why I could also make the legend dynamic: purple is for the thickest/highest tree within the area you're looking at. This way the colors would clearly indicate height/girth differences. The downside of course is that a "red icon" in one area might be a green one if the tree would be there. Colors wouldn't be fixed: the legend would be different for every area. Both options are the same work for me.
Of course ideally, you could choose between a fixed/dynamic one or define your own thresholds or something even more fancy, but in a first iteration I would like to go for one simple option only. I can always extend from there, but I would like to start with a simple design first.
What is preferred by most? Fixed or dynamic colors?
I prefer a dynamic legend above a fixed one. Better indeed would be to have the choice between a fixed/dynamic legend and better still to have the possibility to choose your own thresholds for every map.
For now the dynamic legend as well as the posibility to choose what tree property (girth, height, exact height, etc.) is used for the color are very nice extra's.
Kind regards and thank you!
the new marker colors now on the site. You can choose between:
- exactly measured tree height
- location elevation
The color are dynamic, as explained above. The legend is not yet visible. There will probably be some hiccups, as I didn't test it thoroughly (still got to do something else this evening).
The new possibilities are very nice! Thanks a lot.
I still have one more wish: could you make two categories for girth? A class for single stem trees only as well a class for all trees including multi-trunk trees?
That would make the system better still. As you know Bob Leverett has been talking for years to American Forest-people to get this the rule for the American champion tree lists.
das ist eine tolle Erneuerung. Leider scheint es noch nicht zu funktionieren. Bei mir erscheint beim Umfang 0 m-8 m und dann immer 8 m-8 m.
I have two very tall silver birch trees in my garden. I estimate they are around 90 feet tall and are worth measuring
please advise how I can take this further
Thought to be the very first introduction of Sequoia in Europe, but it cannot be as the gardens have been redone late eighteenth century. You will have to continue your quest Marc! (=Marc Meyer, Sequoia.eu).
Hi, ECTF. Where did you get the year of planting 1878?
Regards from Spain.
Nice Peter Bourne and you found this tall beech. I already thought it strange the UK did not have more beeches of over 40 m tall, as we have a few in the much smaller Netherlands. I suppose in sheltered valleys there will be some more.
Lovely! Is this also known as a copper beech?
Thank you to mach, these copper-beech stands directly on the large fountain of the famous' Sanssouci Palace.
Do you have a close-up photo of the foliage, please?
Seems a highly unusual location for someone to plant a rare hybrid. Are you certain it isn't just Abies alba?
I don't have photo of the foliage, but i'm not sure that an hybrid.
it's possible that just an abies alba. I do the modification.
thank you for the warning that I should be best.
Indrukwekkende tulpenboom! Heb je deze bij toeval ontdekt? Het is verreweg de dikste tulpenboom waarvan ik heb gehoord, zelfs in de VS schijnen er niet zulke dikke exemplaren te zijn. Wel wordt de omtrek geflatteerd door de zeer breed uitlopende wortelaanzetten. Je hebt de omtrek gemeten op 1,50 m boven de bodem / het maaiveld. Heb je daarvoor het laagste / het hoogste of het gemiddelde niveau rond de stam gebruikt?
Dat maakt bij deze boom veel uit.
Wat betreft de hoogte: hoe lang is de jongen? Als de overzichtsfoto van forse afstand is genomen, is de boom wellicht 19 x zijn lengte.
Groeten, Jeroen Philippona
Quite a nest in that old tree. What bird would make this nest?
My first guess would be a stork ("ooievaar").
I was thinking that. Not only is there a wonderful old tree, but a lucky old nest as well. Storks are supposed to be good luck I think
Thank you for your response
Sorry, I wrote text in the English version of this site. Will add the same information in Dutch version.
That is quite alright. I do speak English.
I wonder if the poor tree cannot be saved perhaps a nest could be constructed on a tall pole. This is done where I live to encourage and maintain osprey's.
I loved the photo of the stork in the nest.
Kunt u me ook vertellen hoe weet dat dit een Tilia tomentosa is?
Hallo Mich, aan boomvorm, takstand en door 35 jaar ervaring, de cultivar is Tilia tomentosa 'Pendula' om precies te zijn.
Welkom op MT. Kan je deze foto iets bewerken (helderder maken) en in de goede positie opnieuw uploaden?
Veel plezier met vinden, meten, fotograferen en toevoegen monumentale bomen.
Vorig jaar is de grond onder de boom gefreesd om daar Rhodo's te planten. Het lijkt er op dat de Ginkgo daar last van ondervindt.
Dit is zo'n geval waar ik eerder over berichtte. In Windows 8.1. plaatst de verkenner de foto's automatisch verticaal.! Om hem in de juiste positie te krijgen, moet je de foto eerst met een fotobewerkingsprogramma roteren en opnieuw laden. Pas dan wordt die in de juiste stand zichtbaar.
Helaas krijg de foto niet in de juiste positie.
Hi Mich, Je kunt met een goed fotoprogramma te foto's eerst 90graden draaien en ze daarna uploaden. Hier heb je een voorbeeld van een dergelijk programma. http://www.zoner.com/en/download-request
; Het is veilig. Wel even opletten bij het installeren dat je custom installeert en vinkjes uitzet.
Hallo Mich, welkom!
Maak je maar geen zorgen over die gedraaide foto's.
In de toekomst voeg ik een "roteer" knop toe op elke fotopagina zodat je elke reeds geuploade foto gemakkelijk kan draaien. Eens dat er is, kan je deze en andere foto's draaien zonder ze zelf te bewerken en opnieuw te uploaden. Laat deze dus maar gewoon even staan.
Thank you for all pictures you have registered !
György Pósfai makes a very nice work for all datas of the country that he found, but he didn't submit pictures for the trees.
Thank you for your remarks, now I see it has been worth uploading the photos.
Actually, György has his own homepage: http://dendromania.hu/index.php?lang=en
Here you can find the latest versions of the Hungarian lists, and in the list you can click on every specimen. Many photos and in some cases additional data (e.g. height) can be found here. And there is a photo gallery which is updated regularly.
Hi Laszlo and Sisley,
Indeed very nice you have uploaded photos of Hungarian trees. Actually, Tim Bekaert and I asked György if we could place all his data at monumental trees. He allowed us to do this and sent the whole list without photos to Tim, who added it to the website.
This was a few years ago, after Tim, Leo Goudzwaard and I had proposed to the European Champian Tree Forum (ECTF) to make www.monumentaltrees.com the central database for the ECTF, because it has the possibility to make a common champion tree database of all European countries.
This proposal was not taken over by the ECTF organisation, although we put many Dutch and Belgian champion trees at MT. Also David Alderman and later Owen Johnson decided to put the top trees from the British Tree Register at MT. Aubrey Fennell added many champion trees from Ireland to MT, as did other people for Germany, Poland, the Czech Republic, Latvia and other countries.
So this goal of having a common database for trees of all of Europe (and if possible other parts of the world) is still getting nearer.
A tree database with reliable measurements as well as good photos always was an important aim for MT. Because of this we also gave instructions about tree measurement, beside girth measurement especially of height measurement.
But of course the photos are also very important, so thanks again!
Er staat wel degelijk een Sequoiadendron giganteum voor het kasteel in Perk.
Deze zou één van de overblijvenden zijn van een groep van drie. De boom heeft geen hoogte in verhouding met zijn ouderdom. Vermoedelijk is de top ooit door een storm afgebroken.
bedankt. Ik heb het aangepast op kasteel De Ribaucourt door te klikken op "Wijzig gegevens van de boom". Dit kan je ook zelf doen.
Ben nog niet helemaal vertrouwd met de werking van de site, maar een fantastisch initiatief.
Ik stuitte net op deze foto. Prachtig!!
Bedankt Wim. Ondertussen heb ik wel vernomen dat deze bomen uit Spanje werden ingevoerd om verkocht te worden aan rijke eigenaaars in Provence. Groetjes. Marc
Hallo Hans, dit is een Leylandcipres, Cupressus x leylandii, een zeer groot exemplaar voor zijn soort.
hartstikke bedankt voor je toevoeging. Zoals je zag twijfelde ik ook al. Toevallig vandaag nog een inzet van een kegel toegevoegd aan foto 3. Het heeft wel de achteroverleunende uitstekels die ik ook bij de nootkacypres zie. Waar zit precies het verschil precies in?
Ik verander in ieder geval de tekst bij de boom.
Met vriendelijke groet,
Espectacular rebollo, sin dudas, pero ¿2000 años no son demasiados? Hay un rebollo catalogado en la zona (supongo que es el mismo ejemplar) al que se le atribuyen 300 años http://arbolessingularescyl.blogspot.com.es/2010/07/rebollo-de-los-manaderos.html
Hello Alberto, what a great picture!
About the age, more than 2000 years is indeed too much. This was caused by a recent problem that caused the "year of planting/germination" to be "year 0", causing an age of 2015 years. I will look into it as soon as I have time.
Muchas gracias Monzon,
No se que error hay en el sistema, dice que los árboles fueron plantados en el año 0000, da igual la edad que le pongas.Tambien ha pasado con un roble común reportado recientemente en Dinamarca y con un pino salgareño reportado por mí hace un par de días. Intentaré marcar la edad correcta de nuevo.
Efectivamente es el mismo árbol del blog y de la página de turismo de Avila y debe tener alrededor de 300 años.
Hi tim. thank you for your comment.
I try to put that was planted in 1700 but always goes the year 0000 there is an error in the system because it has gone well lately with other trees.
Hi Alberto, the problem is solved. I have set the planting/germination year to 1700 +- 80 years. Feel free to change it if it is not correct.
Ok Tim, thank you very much.
Looks like a.cissifolium to me, very thin red petioles. This is the foliage from the same tree, photographed last Summer.
also the samara's are really Acer negundo, cheers, Leo
Bonjour, Je vois que vous signalez ce Sequoia comme disparu. J'y suis passé ce samedi et l'arbre est bien vivant entre la ferme castrale et l'église de Hermalle-sous-Huy.
Bien à vous,
Je vois que vous avez barré le Sequoia de Hermalle-sous-huy (entre la ferme castrale et l'église d'Hermalle). J'y suis passé samedi dernier et je peux vous dire que l'arbre est toujours là et bien vivant. ;-)
Bien à vous,
that is an amazing photograph!
Welcome at the site. If there is anything I can help you with, don't hesitate to ask.
thanks for the welcome, if it is an amazing photo, is a true witness to history, when i was in front of him was incredible I felt so small, it is way too beautiful !!
The Monumental Tree along the path. You've to arrive in the village, to follow the road up to the parking lot in Pian della Regina, to walk around 1,5 / 2 hours following indications to Rifugio Zanotti in Vallone del Piz.
That is a magnificent photo, Tiziano!
Thank you Tim. I'm working on a new book all dedicated to big trees and old forest at the top of the montains...
Leider mußte ich heute feststellen, daß alle großen Bäume im Kurpark, der Geldgier des Besitzers zum Opfer fielen. Irgendwie war ich der Tränen nahe, da es sich um einen der ersten Plätze handelt, den ich in MT reinstellte.
Möge den Besitzer der Blitz beim Scheissen treffen!
PS: Die großen (7-8 m) von Petronell sind angeblich auch weg, muß ich aber erst überprüfen
In what way the owner makes money with the felling of these trees?
some new functionality: it is now possible to see elevation profiles for any species. An elevation profile shows how many trees are registered for each elevation or altitude interval.
It also works for varieties/subspecies/cultivars/... There is a link to these pages on each species page.
It has also been possible to see a location's elevation or altitude on the image pages as you might have noticed.
This info might not be useful for trees in flat countries like e.g. the Netherlands but it might be interesting to see how well some species do elsewhere and at what altitudes.
prachtige knothaagbeuk in het Meerdaelwoud, dit is geen meerstammige boom, dus kun je wijzigen, altijd leuk om in het vervolg omtrek te meten, Leo
The variety 'Versicolor hs golden spots on the leaves. But as this foto shows, the spots are not located at the outside of the branches, but a little lower, so the averall look of this tree is not 'versicolor' but rather green.
Thanks, the foliage of the photo I uploaded doesn't really match the photo you uploaded, it has the golden down the middle of the ends of the branches.
I have been checking the images in Van gelderen D.M., Van Hoey Smith J.R.P., Conifers, Timber Press 1996, page 154.
I must admit the description you give fits better to what the images in this book show.
Or, our plant is wrong labeled, or the plant is too much shaded and shows very bad colour.
This is probably the yew that was reported as 364cm girth for Loudon's Arboretum et Fruticetum Britannicum in 1835-7. 'Rediscovring' a tree after a 180 years' gap doesn't happen every day - well done!
This is very interesting, I will upload a picture of the tree if this would help. Would you have any idea whereabouts in this book that it mentions this yew tree? I have been looking through the book online for the past hour and a half and I couldn't find anything mentioning Gosford... Although I could be looking at the wrong volume perhaps?
There are four volumes of text in Arboretum et Fruticetum Britannicum (and four of illustrations). A few years ago when I added the trees in them to the Tree Register, all were available online through Google Books, but last time I looked I was only able to find later editions of one or two of the volumes. I think the species are arranged family by family but I can't remember which volume Taxus is in. Under Taxus baccata there should be a long list of specimens measured by Loudon's corespondents, arranged in approximate geographical order. Having said that, the records for Taxus had already been imput onto the Tree Register by Alan Mitchell many years ago and I didn't check through them all, so it's just possible that an error has crept in somewhere. Let's hope not, as the match seems such a good one!
I found the long list of recorded trees, there is a mention of Gosford but it is Gosford House in Edinburgh, however, I don't think the measurements for this tree in Edinburgh match the 364cm that you mentioned.
It must have been the Scottish Gosford. We had problems when we were transferring Alan's card-index register onto computer when different sites shared the same name. There may in this case have been a mix-up between girth and diameter as well. A pity as it would have been good to find a previous record for your big yew.
On the left is the foliage of a neighbouring common yew, showing the difference in foliage between that of the common yew and this tree.
Looks like just a long-leaved cultivar of Common Yew ;-)
Thanks for this, didn't know there was a long leaved cultivar of the common Yew, bark is still different to other Yew trees though.
WW and Conifers,
Longer leafs, more pointed leafs. I don't know the species, but is Taxus chinensis possible?
Greetings, Martin Tijdgat
If the fruit suggests a Podocarpaceae, then perhaps a Prumnopitys sp (sometimes called yew pines, along with Podocarpus macrophyllus). I'm not familiar with old world candidates.
Matt and Martin,
I will have a closer look at the tree tomorrow, it is very yew like in appearance but the leaves are nearly twice as long as the common yew and the bark is definitely softer than that of the common yew, you can peel tufts of it off.
I've seen one or more (un-named) Taxus baccata cultivar(s) with leaves this long. But the soft bark is odd; that doesn't fit any Taxus well. Cones ('berries') would help, if there are any, but January isn't a good time (and even in autumn, there's still a 50% chance it might be male!).
It isn't Prumnopitys andinus, and I doubt any other species in this genus either.
Prumnopitys and Cephalotaxus can be easily recognised when bending te leaves. When you bend them, and they break when bended completely, it will be most probably Prumnopitys or Cephalotaxus. If not, yu can exclude both genera.
Prumnopitys also has pale stomata where those of Taxus are green.
Conifers, I will have a look for any signs of fruit or cones, but as you say it might be the wrong type of year for it.
WiPe, I will bend the leaves then to see and I'll have a look at the stomata, thanks for this.
Conifers, the bark is softish and as I mentioned before you can also peel bits of it off in tufts, definitely not smooth or Flaky as common Yew is, especially for a tree this age.
Keep a look out for pollen cones too - they should be in bud or just starting to open at this time of year. Taxus scattered or in rows on the underside of the shoot, Cephalotaxus in dense rows on the underside of the shoot, Prumnopitys in stalked clusters.
I have added a foto of the stem of Prumnopitys andina. This stem is only 17 cm circumference, thus rather small.
In my opninion this tree is far to young to call it a monumental tree. i have just added fot your help on this one. I will not keep it on the side but for a few days.
I have also added an image of the backside of the needles. The needles are hardly bigger as those of Taxus baccata.
Prumnopitys andina again (at RBG Edinburgh), a male plant with pollen cone panicles developing bottom centre and right:
Underside of P. Andina leaves look similar but the picture of the foliage from RBG Edinburgh shows no similarities, I will check the pollen cones this afternoon.
Hello all, I've uploaded 2 images of what I found under the shoots on one of the branches.
Thanks! Those are dried-out / undeveloped Taxus seed 'cones'; so definitely a yew; most likely a cultivar of Taxus baccata, given the rarity of other yews in cultivation.
Thanks! This would make sense as the tree is definitely very yew like in appearance and I actually thought it was a Yew until the other day when I decided to have a walk underneath it and found it to be slightly different.
WW and Conifers,
So it is no longer an undetermined species, but "a" Taxus. Taxus baccata, Taxus x media, or another Taxus? Is there a picture of the whole tree?
Not Taxus sumatrana
(syn. T. celebica
); that has different, very distinctive foliage. I'd stick with a T. baccata
As an aside, that www.worldbotanical.com website is highly unreliable, splits Taxus up into a multitude of "species" on the flimsiest of evidence; it is not accepted by any other taxonomists.
I can't add to this thread, other than to remark that Taxus cuspidata seems to be the only other Taxus that wants to reach tree-size in Britain/Ireland, and that the bark of the big old one at Borde Hill is a bit sponger and browner than common Yew, but the leaves are no bigger.
Wouldn't be sure with the foliage of T. Cuspidata but the spongier bark sounds familiar. I wouldn't feel confident in distinguishing between the pair, are there any known cultivars of T. Baccata with spongier bark?
