Very nice. This tree seems to come right out of a fairy tale.

Keep up the good work, Zeltins!

Hi all,

As this database is developing more and more into a podium where you can find all kinds of answers relating to pictures, growth, size and dispersion of all kinds of trees, in my opnion, there is a moment of realizing what we are doing and what our aims are.

Please don’t take it as an attack or offense. I saw that Karlheinz is very sincerely and thoroughly describing what we can see in the Kleve gardens in Germany. Karlheinz has an attitude inwhich he wants to be scientific and thorough.

I am wondering if that is what we should do here. If I take in account the detailed contributions of the Kleve gardens I soon stop scrollin

g the pictures. Off course that’s not a problem, but it poses the essential question of our focus or aim. What do we want? Scientific registration and documentation or something else?. Nice pics of trees that matter?. And do we want to influence laymen or other potentially interested people?.

I start thinking about a website where we can see the nice pictures or (on another place) view the scientific correct database about trees, what they are and where they are to be seen.

To be honest I would like to see both.

I would appreciate a site where you can see the champions per country, city or region. And in connection with that, I would like to go deeper and learn more about the characteristics of a special tree.

Is this a positive contribution? I hope so. It is intented so. I value the work of Tim. Next to that I think we have to help Tim in finding his way in accordance with the users and contributors of the site.

Crack your minds please and have a nice day.

Simple answer for me, scientific registration and documentation for me, I come on here to view and see champion trees, my priority interest I admit is height but I also appreciate girth. I could upload pictures and register thousands of trees but I only register those of significant height either for species or location. The artistic photo thing does not bother me, I just want to see the trees whatever they look like. In truth the artistic element can be irritating as all it ever does is cause handbags at dawn with people upset at ratings of photographs. I would delete the rating system from this site if it was mine to end this dispute for good.

Wim Brinkerink, op 2014-10-06 17:25:38, zei:
My commitment in this discussion is not the rating. Nevertheless thank you very much for this opnion. We need that.

TheTreeRegisterOwenJohnson, op 2014-10-06 18:24:21, zei:
That's a good point, Wim. If the site were to feature every 'monumental tree' in the world there would be many millions and Tim would have to work even harder to keep the software running smoothly (and pay even more for bandwidth)! But many countries already have extensive, even near-comprehensive, databases of their notable trees. In Britain and Ireland, we have the Tree Register (with 215,000 trees) and the Ancient Tree Hunt (with 150,000 trees), and I've only transferred a very few of our best trees onto Monumental Trees, which I would like to see as a showcase for really special trees which can stimulate interest in a wider public (and act as a cross-borders forum for the initiated).

If anyone wants to find out about the rest of our UK and Irish trees, I hope that they would be sufficiently interested to join the Tree Register and consult its online database. The same applies for the USA, New Zealand and several European countries. Conversely, if anyone has an interest in updating and adding to the data on the Tree Register, I would hope that they would liaise directly with myself as Registrar. (A few trees have gone onto Monumental Trees instead and I have to search this site to find them and transfer them onto the Register. So long as it's only a few, this is a comment, not a complaint!)

Perhaps the links to individual countries' national tree database could be displayed more prominently on the main page of Monumental Trees, so that people with special interests are redirected to these sites. If Monumental Trees is to act as a large-scale database in its own right, I think some redesigning would be needed, so that it's quicker to draw up lists of, for example, particular species in particular provinces or counties, and to order these in different ways.

Tim, op 2014-10-06 19:15:17, zei:
I have stated my opinion on the goal of this website before. It is not my intention to copy or compete with national registries, it is merely about offering anyone the possibility to document loosely defined "trees of interest", so there is room for everybody: those that find pleasure in comprehensively documenting trees in an area, those that like to have a relaxing browse through photographs of interesting trees during some spare time in the evening, those that are merely interested what is to be seen in their neighborhood, those that have a scientific interest in how trees of a specific kind in this or that area compare to anywhere else in the world, to promote tree hunting, to offer statistics for the record hunters, to offer a possibility for photographers to share and persist their photo collection, ... , and yes, because I also like the technical aspect of it and for me it is rewarding to see that what I made as a hobby is actually being used by people and visited by many more. There is still a lot of potential towards the future, e.g. growth curves using historic measurements and - related - automatic age estimations.

That said, indeed, Owen, the "link" section definately needs some updating (after which I could make it more prominent). I'm not sure who has edit rights there, but that page is editable, so feel free to add links to "official" tree registrers or databases anywhere in the world.

Kind regards,

Hallo Wim,

wir haben unterschiedliche Meinungen, welches Maß an Sorgfalt wir aufbringen sollten bei der Registrierung von Bäumen. Nach meiner Vorstellung soll die Baumdatenbank von MT nicht nur eine Plattform zur Präsentation eigener schöner Baumfotos sein, sondern wir wollen auch der Allgemeinheit eine verläßliche Informationsquelle bieten.

Wenn sich etwas als offensichtlich falsch herausstellt, sollte es erlaubt sein, das Problem anzusprechen und um Korrektur zu bitten. Ein Beispiel aus dem von dir angesprochenen Park in Kleve verdeutlicht, was ich meine:

douglasspar (Pseudotsuga menziesii) '16910'

Die Douglasie auf dem Foto hat nicht die Höhe und den Umfang des hier registrierten Baumes (ich habe gemessen: Umfang 3,04 m und Höhe 30,1 m), es muß also eine Verwechslung vorliegen. Das Baumschild auf dem zweiten Foto hängt nicht an diesem Baum, sondern an einer anderen Douglasie. In der Umgebung stehen mehrere Douglasien, einige auch erheblich höher (bis 38,80 m). Die registrierten Koordinaten sind ungenau und lassen eine Identifizierung des Baumes nicht zu. Bei solchen Ungereimtheiten macht es für nachfolgende User keine Freude, hier weitere Douglasien zu registrieren.

Grüße, Karlheinz

my English translation:

Hello Wim,

we have different opinions, what level of care we should apply for the registration of trees. In my idea the tree database of MT should not only be a platform to showcase our own beautiful tree photos, but we want to offer the public a reliable source of information.

If something obviously is found to be wrong, it should be allowed to address the issue and ask for correction. An example from the Kleve gardens, named by you, illustrates what I mean:

douglasspar (Pseudotsuga menziesii) '16910'

The Douglas fir in the photo does not have the height and the girth of the here registered tree (I measured girth 3.04 m and heigt 30.1 m), so there must be a confusion. The board on the second photo does not hang at this tree, but at another Douglas fir. In the surroundings there are several Douglas firs, some significantly higher (up to 38.80 m). The registered coordinates are inaccurate and do not allow an identification of the tree. With such inconsistencies it makes for following users no joy, to register more Douglas firs here.

Greetings, Karlheinz

Wim Brinkerink, op 2014-10-07 14:26:39, zei:
Hallo Karlheinz,

I don't have any problem if you correct me. Be my guest if necessary, I also would like it if the information, of whatever kind, is correct.

Kind regards


RedRob, op 2014-10-07 16:45:27, zei:
Am I one of the guilty ones Owen, thought that you might be getting sick of emails and that you might pick them up on here but so many trees registered it is hard to keep up if you are away for a few days I admit.

Could the site be split, one part for scientific measurement, precise recording of location, photographing and ranking of significant trees (which also acts as a full record for these trees if they later happen to be lost or are felled) the other half for architectural trees for those who enjoy looking at the photographs and voting on composition. The two groups could then be happy.

Wim Brinkerink, op 2014-10-07 18:07:56, zei:

Tim, op 2014-10-07 18:45:55, zei:
Hi Wim,

I read you apparently register trees with an inaccurate location and assign pictures of other trees to it, likely just to have that particular photo or photos uploaded.

That of course is not what should be done. Instead of expecting others to correct it for you, it would be much better not to enter incorrect data, and to refrain yourself from uploading pictures if you don't remember exactly of which tree it was. I for example have quite a few photos of great trees (e.g. chestnut trees in Corsica, or baobab trees in Zambia) from my travels which I did not upload, because I cannot find back the exact location.

Kind regards,


Wim Brinkerink, op 2014-10-07 18:49:10, zei:
Dear friends,

I'm sorry if my contribution makes people believe that I am starting a controversy or antagonism. Please disregard my remarks. i will refrain from this kind of discussions. Apparently it is not appreciated.


Wim Brinkerink, op 2014-10-07 19:06:00, zei:
Hi Tim, Your conclusion is inaccurate. I uploaded pictures with the correct coördinates. My exif data will prove that. Please don't jump to conclusions on an incorrect comment of Karlheinz.


Wim Brinkerink, op 2014-10-07 19:19:03, zei:
Hi Tim,

A replenishment to my earlier reaction. I have spoken to you earlier about the fact that I didn't upload some beautiful trees in Mexico, because I didn't have the right coördinates. Since a few years nobody can accuse me of not posing the right coördinates. I have had about 4 camera's with gps function. So please ferfrain of accusations please. That's pissing me off.


Karlheinz, op 2014-10-08 06:14:03, zei:
The Tree Register or something similar, where large trees are documented, there is not in Germany. Who wants to document large trees with measured values ​​is dependent on Monumental Trees. In Germany there is still the Championtree list, where trees with thick trunks are recorded, but tree heights are rarely measured.


Karlheinz, op 2014-10-08 10:34:01, zei:
Also my camera can store GPS locations in the Exif data area. But more exact coordinates I achieve with both my Garmin GPSMap 60csx and my modern smartphone Galaxy S5 with a suitable app. The accuracy is always dependent on the local situation and the care of my measurement. In special cases, I also measure by rangefinder the distances to striking objects in the terrain. Because a direct coordinate input in MT is not yet possible (hello Tim!), I set this measured position by the method "trial and error" in the map (satellite or map view). Then I check this position in the map for plausibility and correct if necessary.

In my experience the Exif coordinates in the photos of cameras and smart phones are a great help, it avoids rough error of positioning, you always will hit the right park. But for the exact positioning of the tree within the park, it is not enough in most cases. Of course there are differences in quality of the GPS features of cameras and and also your handling is crucial.


TheTreeRegisterOwenJohnson, op 2014-10-08 17:55:34, zei:
A few more thoughts (Tim and Karlheinz). A record of a monumental tree is interesting straightaway, of course, but after 50 years or 100 years it will be even more valuable, because the tree will probably still be there but people might not know about it until the find the old record. (And we won't be there for them to ask.) The change in girth will then help people to estimate the ages of trees in more situations, without having to count the rings.

This means that it is worth thinking how the data on a site like Monumentaltrees might be curated and kept safe and available into the future. A paper record is easily curated, and a robust database can probably be kept up-to-date as technologies change. But I suspect that digital image files might not be decipherable in 50 years time, and a pin on a Google map certainly won't be! I've been able to relocate nearly all the trees recorded in Britain 50 or 100 years ago, even though at that time they didn't have GPS, or camera phones, or even map grid references, so I don't think that putting the icon on exactly the right spot on a map is necessarily essential.

If recorders want to adopt Monumentaltrees as the place to store their records of German trees, you might in the longer term even have to think about creating a charitable Trust to curate the site's information.

Tim, op 2014-10-08 18:46:02, zei:
That's right Owen. I also often think about that. As the data (measurements, locations, coordinates, image files) are all digital, they can in fact be stored and maintained indefinitely. All physical digital data carriers like e.g. dvds or hard disks eventually become unreadable, but as long as the data (which is just of sequence of 0's and 1's) is copied over once in a while, the data can live forever.

As I'm a still a young man (currently 32 years old) I plan to be around for many decades to come. The site's content is kept safe not only by the site's hosting company, but I also often make backups on dvds.

If I would be run over by a truck tomorrow, the site would probably stay alive and be accessible for a long time, as long as my automatic yearly payments are done. The data on the dvds would still available for anyone interested. Anyone with an even limited IT background would be able to get the info back. But indeed, in the long term, I would have to think how to share with others. Maybe even make the entire content downloadable by other registers or something.

Kind regards,


Karlheinz, op 2014-10-08 22:12:00, zei:
Owen, if all other details are contradictory, the coordinates would help you!

Jeroen Philippona, op 2014-10-09 06:32:25, zei:
One reason for Owen to be able to find many of the trees from descriptions of 50 to 100 years old is probably that these are mostly really big trees (often open grown) or very special species and specimens. Karlheinz often looks for very tall (but not especially fat) trees in forests, wich is more difficult.

But Karlheinz has the most exact methods of all members of MT. We cannot expect from all members to work as exact as he does, while MT is not an Academic research institute with professional scientifical goals.


Karlheinz, op 2014-10-09 12:59:12, zei:

I do not claim for myself, to work using scientific methods and I do not expect that from other members. I will not make MT to an Academic research institute or something similar, I do not know who has put such thoughts into circulation. I am not saying that my measurements and records are error-free or that it would be the most accurate of all. I know and take into account the tolerances and limits of my own and by others commonly used measuring instruments and methods.

The point here is that a certain level of accuracy should be aimed and that there is the willingness to correct obvious errors. The stored data here must be traceable and verifiable for others. It must be allowed in MT, to report errors and to call for corrections, without one immediately be treated with subliminal hostility. A preservation of the status quo for the first registrator, or something as the right to sole ownership must not exist. An attitude "this is my tree, I have registered, keep out there!", I will not support. I have in mind that not only new trees are added, but also the database of the already registered trees will be maintained and updated (example: Wikipedia). If so I make unpopular myself with some members, I must live with. Should I have to recognize that MT developes in another direction, I see no future for me in MT.

Oh, nice one. I apparently forgot to register "Georgia" as a country. No tree there would have appeared in the location lists, that is now solved (it was also the case for Denmark).

Thanks for letting me know.

The Hirnant valley is actually just into Gwynnedd, with the watershed to the south-east forming the boundary with Powys. But I don't think there's an easy way to change the county.

Tim, op 2014-09-30 10:14:37, zei:
This would work (for those having the rights to change a tree's location):

  • On the "Add tree" page, add a location in Gwynnedd

    This is filling up the page until you can select "Add new location" and click 'Save' there.

    Don't proceed as this would add a tree there, which you don't want to do.

    After this, you have an empty location in Gwynnedd

  • Go the page of tree on the old location and move it.

    This is: going to "edit data of tree" and selecting your freshly created empty location.

    It should appear in that list of choices.

Everything will be updated and the old location (now empty) will be removed from the lists.

Kind regards,


TheTreeRegisterOwenJohnson, op 2014-10-01 17:09:35, zei:
Thanks Tim. I'll consider correcting all the errors of this kind which I can find for the UK, when I have more time! You may remember that 'City of London' and 'Greater London' appear as two counties, and that some sites such as Kew Gardens are duplicated under both 'counties' - this could do with rationalising.

Something we could never imagine has been written down in an article in the newspaper Ouest France of septembre 24th

A beautiful yewtree that is part of the remarkable repertoire of the Conseil General (C.A.U.E.), will disappear very soon. Before winter, from this yewtree, aged above a millennium, growing in the cemetery,there will nothing left but the memory and photos. The venerable tree has become dangerous.

A great disaster for the community. This yew, placed close to the tombstones, near to the church has seen many parishioners, year after year, strolling under its branches. What did happen to the tree? On august 19th, explains Pierre Pitrey, the mayor of Mongardon, a survey has been carried out by a company, specialized in arboriculture and city forestry. This yew tree shows very bad machanical defects on its stem and its rootcollar.

In simplified language: this yew tree is hollow and multiple cracks at and around the trunk threaten the direct environment of the tree. Verdict: He should be killed, for the security of people and property. The paperwork is being prepared for slaughter by professional pruners, as it will not be easy to cut this tree down. The veteran tree is located very close to the to the church and cemetery. This will be costly for the municipality, approximately € 3,500, between diagnosis and slaughter: and its beautiful foliage and trunk will end for disposal.

This is a tree with a circumference of more as 9 metres.

The yew , with and estimated age, between 1000 and 1200 he was honored in 2005 as a remarkable tree of Le Manche department, and listed as such by the C.A.U.E. Its circumference is 9 to 10 m, it has a height of 9 m and a crown of 11 m circumference. Its powerful trunk is leaning heavily, but seems stopped from falling by a tombstone, slipped under the bulge of the trunk, which seems to help keep the tree in balance.

The reaction of Les Tétars arboricols:

This millenium old yew tree would become dangerous?! And the only solution would be to cut it down ?! I am totally appalled at how we condemn this ancestor which, I quote, " its beautiful foliage and trunk will end for disposal " ...

Call the city hall to try to influence this absurd and expeditious decision: 02 33 46 04 65

Tim, op 2014-09-27 17:22:19, zei:
It is indeed sad that during the course of many centuries, only one action of single human is necessary to end a tree's life.
WiPe, op 2014-09-27 17:56:12, zei:
we are really not that far yet. I have the idea that people in France are ready to fighth for this tree.
Wim Brinkerink, op 2014-09-27 18:28:31, zei:
So I have made my statement on the site where French people can read it. I think that's more productive than ststing opinions among us..
TheTreeRegisterOwenJohnson, op 2014-09-29 19:11:00, zei:
I shall forward this conversation to Tim Hills, who runs the website and who has years of experience in campaigning to protect ancient yews when they get condemned by ignorant consultants. He may want to offer his help to a campaign to save this tree, if he's not already aware of the threat to it.

New functionality: cultivars/varieties/subspecies/...
Zichtbaar voor iedereen · permalink · nl
Tim, op 2014-09-26 16:23:44, zei:

today I added new functionality:

  • on the "all species" page and on the page of each separate species (example) there used to be non-clickable lists of its cultivars, varieties, subspecies, ... Now these links are clickable and counts are shown.

  • added rudimentary variety pages on which you see some information (photos, ...)

    - changed the display of subspecies, varieties, forma, cultivars, and cultivar groups per Conifer's suggestion

    - allowed seeing cultivar/variety/... photo lists ( of red beeches)

I hope this can already be helpful.

What still needs to be added:

  • adding the possibilty to filter down to cultivar/variety/... on the location lists and record pages

  • for some users: being able to edit the cultivar/variety/... information (e.g. change name, change type, remove, ...).

Kind regards,


Conifers, op 2014-09-26 20:27:54, zei:
Excellent, thanks! I am starting on some nomenclatural tidying (e.g. Pinus nigra "var. austriaca" is an invalid synonym of Pinus nigra subsp. nigra).

Conifers, op 2014-09-26 20:33:04, zei:
Addenum: the text on specimen pages still needs a bit of tidying, e.g. here it says "The tree is a specimen of the cultivar 'nigra'", whereas it should say "The tree is a specimen of the subspecies nigra".

Wim Brinkerink, op 2014-09-26 20:42:01, zei:
Hi Tim,

Thanks a lot I'll explore it immediately. At first sight you made more possible than I could have hoped for. I even could select the Querus petrea mespilifolia. Great job. !


Tim, op 2014-09-27 17:19:39, zei:

I will first add the possibility to rename the cultivars/..., change their type, and to delete them (it is already possible for a long time to create them, and to assign trees and reassign these trees).

Once the missing functionality is there, I will give the possibility to a restricted number of users to collaborate, agree on standards and to tidy up the cultivar list. I will post it here once the site's up to it.

Kind regards,
