Die Art Carya illinoinensis wird falsch sein, ist es Carya cordiformis? Nüsse habe ich noch keine gefunden.

The species Carya illinoinensis will be wrong, it is Carya cordiformis? Nuts I have not found yet.

Grüße

Karlheinz

Conifers, à 2014-09-29 17:31:04, a dit:
Both the bark and the foliage are a good match for Carya cordiformis; compare e.g. here.

I agree, Carya cordiformis.
Karlheinz, à 2014-09-29 18:57:16, a dit:
thanks, I have changed to cordiformis.

I asked on the American NTS forum, what they think about the species identity. Follow the discussion here: http://www.ents-bbs.org/viewtopic.php?f=38&t=6633

Thanks Kouta, it'll be interesting to see the consensus there.

For clarification for anyone who doesn't understand bbeduhn's comment 'it is not one of the "true" hickories', the hickory genus Carya is divided into two subgenera, the pecans (Cc. illinoinensis, cordiformis, aquatica, myristiciformis), and the true hickories (Cc. ovata, laciniosa, tomentosa, glabra, etc.).

KoutaR, à 2014-10-01 18:12:06, a dit:
Conifers, thanks for the clarification. I did not understand that comment either.

The Giant Sequoia of Nymans looks like an easy victim for lightening as it towers far above the surrounding trees. To the left also some Sequoia sempervirens.

When I first saw this tree in 1997, it had recently died back about 4 metres to 43m. This could have been lightning damage, though I suspect it was a consequence of the summer of 1995 which was exceptionally dry in Sussex and may have caused the small dieback I've noticed in a lot of Sequoiadendron (but not other species). At the time I wasn't expecting this tree to regrow very far, but I couldn't have been more wrong.

Though it's not clear in this photo, it grows in quite a steep, narrow valley, so that tree-crowns within 400m on almost all sides side rise above its tip. Once it's tip becomes exposed to the prevailing westerly wind, I suspect it will stop growing.

RedRob, à 2014-10-01 17:26:40, a dit:
Any chance someone could visit Haslemere and Polecat Copse and take some new measurements and photograph the trees? Great place to visit when I visited several years ago, a very thin Coast Redwood just above the 51 metre Sequoiadendron intrigued me, took some photos on an old 2mp camera phone but they didn't come out as would be expected.

Hello Rob

Off to Wales next week to see your trees near Waterloo Bridge plus some new ones. Will try to take a look at the Elan Valley Douglas on the way, where exactly are they?

Have you contacted the F.C. (now Natural Resources Wales) about these trees as I think they need a guarantee of protection. Especially it seems very likely they are the tallest Douglas Fir in the Northern Hemisphere outside the Pacific Coast of North America. I am sure they would be very interested. Although some ways better to keep the public quiet about them as having thousands of people trampling around them can be detrimental to their health due to root/ soil compaction, as the F.C often makes a trail to the trees. But letting the forest manager know is I think a good idea. What do you think?

Stephen


RedRob, à 2014-10-01 17:22:42, a dit:
Hello Stephen, http://www.geograph.org.uk/photo/2526900 these are the trees in the Elan valley area.

Owen reported the Waterloo Grove trees to the Forestry Commission last year if I remember correctly. You are right about people tramping around them would cause damage although that said the land in front of them is full of bracken, brambles and hidden gullies. Have a good time, look forward to hearing about your experiences. Take some photos and report your trees whatever or wherever they are.



Jeroen Philippona, à 2014-09-29 21:45:08, a dit:
Hi Rob,

Would be nice if you also measured the CBH of such trees, as it gives an impression of the growth just like the heightmeasurement as well as of the total woodvolume.

Jeroen


RedRob, à 2014-10-01 17:16:07, a dit:
Apologies Jeroen, didn't think that the girth would have altered too much in 4 years so didn't go across the stream to girth it.

Hi Tim,

Ik heb vandaag een acer rubrum geregistreerd. érable rouge (Acer rubrum) '19478' met een afmeting van 2,78 m op 0,90 cm is het een respectabele boom. Als ik de lijst van Acer rubrums zie blijkt deze boom niet serieus genomen te worden. De door mij gedane meting komt niet tevoorschijn en de boom telt kennelijk niet mee. Dit verbaast me. Het is zeker geen meerstammige boom. Hij vertakt op 90 cm maar dat betekent niet dat hij meerstammig is, waarom verschijnt hij dan niet in de normale lijstjes.? Erg onbevredigend.

Kun je eea verhelderen.?

Wim


Jeroen Philippona, à 2014-09-30 19:09:10, a dit:
Hoi Wim,

Heeft Tim toch eerder uitgelegd: de bomen verschijnen pas na enige tijd in de lijstjes, waardoor het totale systeem minder traag is geworden. Jouw esdoorn zal binnen enkele dagen in de lijsten verschijnen.

Jeroen


Wim Brinkerink, à 2014-09-30 19:18:23, a dit:
Maar de boom verscheen al in het lijstje.....Alleen met een niet ingevulde meting..Dat had ik nog niet begrepen.

Ok..Ik wacht gewoon af.


Conifers, à 2014-09-30 20:22:02, a dit:
Maybe the non-standard measuring height of 0.9 m excludes it from the 'stoutest' table? Just like multiple stems affects the 'true' girth of a tree, so does measurement at other than 1.3-1.5 m. I am guessing those two low branches are the reason for the 0.9 m measurement. Did you also measure the girth above those branches?

Wim Brinkerink, à 2014-09-30 20:38:16, a dit:
I didn't. It didn't seem logical at the place. I will have another inspection to be sure.

TheTreeRegisterOwenJohnson, à 2014-10-01 17:07:43, a dit:
On the Tree Register, we distinguish 'B' class trees, where the trunk can't be measured at the standard 1.5m but the measured girth is not significantly inflated by forks etc, from 'C' class trees, which do fork and where the measured girth can't be meaningfully compared with clean-boled trees. 'B' class trees can become girth-champions, while 'C' class trees only appear as alternative champions or as champions when the girth is very much bigger than any others.

On Monumental Trees, the distinction can also be made by answering yes/no to 'does the tree have multiple stems'. But I have noticed that some recorders (eg Red Rob) are answering 'yes' to this in the case of trees that fork higher up in their crown (and where the fork doesn't affect the girth, except that the crown will be broader and might power faster growth).


RedRob, à 2014-10-01 17:13:59, a dit:
Hello Owen, which ones have I done incorrectly, will correct unless someone else will.

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, à 2014-09-30 10:14:37, a dit:
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,

Tim


TheTreeRegisterOwenJohnson, à 2014-10-01 17:09:35, a dit:
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.

RedRob, à 2014-10-01 17:11:56, a dit:
Sorry, my mistake, Vyrnwy is Powys and thought that this would be too.


RedRob, à 2014-10-01 17:09:47, a dit:
Hello Owen, Conifers. There is a small river between my position and the trees and I didn't think anymore about these, thought that they were just European Larch. I could see some bases and tips through the young trees just in front of the camera and measured several around 38, 39 metres in the line in view although one or two could be tadge taller possibly, 40 metres. Perhaps you can see more from Street View if you take a drive?


TheTreeRegisterOwenJohnson, à 2014-09-29 19:46:59, a dit:
From their apparent youth, and location within a FC planted forest, I wonder if these are hybrids (Larix x marschlinsii), but I can't tell for certain from this photo. Larches are easily identified from the old cones which always lie underneath them - did you look?
Conifers, à 2014-09-30 17:43:17, a dit:
From the long, stout branches, I'd agree more likely Hybrid Larch, if not even Japanese Larch.
TheTreeRegisterOwenJohnson, à 2014-10-01 17:02:38, a dit:
For Tree Register purposes, I shall plump for Hybrid Larch as I suspect that true Japanese Larch is rare in FC plantings (while the hybrids are often back-crosses and quite close to Japanese Larch). As such this will be another UK and Ireland height champion. At this rate you'll soon have a clean sweep, Rob.

Something we could never imagine has been written down in an article in the newspaper Ouest France of septembre 24thhttp://www.ouest-france.fr/lif-du-cimetiere-plus-que-millenaire-sera-abattu-2854054

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:http://lestetardsarboricoles.fr/wordpress/2014/09/26/lif-mongardon-en-sursis-manche/

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 " ...

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.

I shall forward this conversation to Tim Hills, who runs the website www.ancient-yew.org 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.

This is not Ch. lawsoniana. I think Conifers is spot on right with Ch. pisifera. A Lawson's cipres is not so open and transparent.

New functionality: cultivars/varieties/subspecies/...
Visible pour tous · permalink · nl
Tim, à 2014-09-26 16:23:44, a dit:
Hi,

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 (e.g.photos 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,

Tim


Conifers, à 2014-09-26 20:27:54, a dit:
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, à 2014-09-26 20:33:04, a dit:
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, à 2014-09-26 20:42:01, a dit:
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. !

Wim


Tim, à 2014-09-27 17:19:39, a dit:
Hi,

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,

Tim

Tim,

Bedankt voor deze nieuwe verbeteringen. Zou graag werken aan wegpoetsen (tik)fouten in namen als je dat toestaat. Zie eerdere mail over fouten in naamgeving Ulmus.

Groet, Martin

Hallo Martin,

ik zal eerst zorgen dat het mogelijk is cultivars ed. te hernoemen, van type te wijzigen en te verwijderen.

Eens dat mogelijk is zal ik een beperkt aantal gebruikers rechten geven om deze functionaliteit te kunnen gebruiken en jij bent er één van gezien jouw Ulmusmail.

Ik laat iets weten wanneer ik zover ben.

Groeten,

Tim

Hi Leo,

Uit de veelheid van bomen heb ik er één gekozen om te meten. Op foto leek deze dezelfde als jij hebt opgemeten. Ik vond echter het verschil van 25 cm te veel en heb toen maar besloten een nieuwe op te voeren. Ik heb overigens de coördinaten aangepast. De strook bomen ligt ten noorden van de Ravensteinselaan en ze zijn op de kaart goed te onderscheiden omdat er twee paden doorheen lopen. Jij had ze ten zuiden van de Ravensteinselaan geplaatst.

Groet

WIm
