Only two Common Laburnums registered! I wish I had realised this as have seen quite a few good sized Laburnums, probably around 10 metres, but didn't record them as have been meaning to visit Wakefield Castle to measure and confirm the B&I champion height there, 17 metres if I remember correctly? They are lovely trees when in flower. Will have to now try and remember where I have noticed some of the Laburnums.
Hi Rob - you'd need to check identities carefully. 'Common' Laburnum is actually far from common in cultivation now, and rarely exceeds 6 metres or so tall. Larger ones are almost all Alpine Laburnum L. alpinum, or (most frequently of all now) the hybrid between the two, Voss's Laburnum L. × watereri 'Vossii'. Distinguishing them is fairly tricky; I suspect the ones in these photos here are Voss's, but can't confirm it without close-up pics.
Intriguing that you stumbled upon this tree. Don't know how you see it, but in the 60's and 70's the babyboomers in Holland, judged this species as a thoroughly "burgerlijk" plant/tree. A lot of people (probably outside the world of agriculturalists, naturalist and dendrologists) defied this trees.
I used to be one of them. By now, I am a bit independent and judge everything without prejudice. And true, Laburnums can be very nice. That's what a lot of people in Asia think.
I saw this tree way back in the early nineties, it was flat topped. Yes very luxuriant and healthy. Judging by the fresh fissures in the bark I would say it is still growing rapidly in girth. The trunk also has very little taper and I would not be surprised if it contained 60m3 of wood. It may reach 55-60m eventually but may take another 30 years?
A species which has not reached its full potential in the UK and with climate change, could well excel in the west. It is virtually bombproof with only man/wind/lightning the real hazard. With Giant sequoia Honey fungus and other decay fungi can attack these trees but not Coast Redwood.
Stephen, were the footpaths open on the south west bank of the river through the Dell? I really wanted to have a go at measuring the Corsican Pines which were planted as a shelterbelt and which Owen recorded as 43 metres in 2005 but the whole area was fenced off with 'no admittance' the day that I visited. I could see them but couldn't get any view of any bases? Don't know what was going on that day? I could also see the Nordmann Fir but not the base? 45 metres is the B&I record for Corsican Pine and these had probably or possibly overtaken that? Did you photograph them or attempt a measurement?
The 'no admittance' signs are just for the general public - if you ask at reception, they'll (usually) give you permission to go over them once they know why you're there if it's a special reason like measuring trees. At least that's how it used to be. All they'd likely ask of you is to give them a copy of the measurements afterward.
Hello Conifers, you may be right. The paths up the hillside were blocked off with pink ribbon which I thought unusual and that something may have happened further up, perhaps unsafe paths or a landslide?
I've just added some historic measurements for this tree. It's growing remarkably steadily! (Tim, one feature that could be added is a calculation of annual growth-rate between the planting date and the first measurement for trees with known planting dates?)
Rob, the Corsican Pine was very difficult to measure tangent-fashion, as they generally are, and it could have been more than 43m. But probably also hard to see the highest shoots with laser. As it's part of the official 'shelterbelt' it may not have added more height. Much of the garden was also shut to the public on my visit in 2005 - is this a permanent condition? I know that recently Bodnant has been undergoing 'restoration' at the urging of various influentual landscape gardeners. This is a word that always fills me with dread as it generally means cutting down the existing 100-year-old trees and planting new ones to 'recreate the spirit in which the garden was originally conceived' or words to that effect. At least they've spared this one.
Hello Owen, perhaps we need a petition from someone, the Tree Register members perhaps amongts others to protect these older trees, it would be tragic if any of the tall conifers and others were felled just for the sake of it, they are irreplaceable.
This Coastie doesn't grow very fast does it, I measured 51 metres for it MT standard reading (centre of base on slope), Tree Register standard it will be about 50.4 metres I estimate, the girth probably now 6 metres perhaps taking into account Stephen's comments. It looks glaucousy as you described so will it be some sort of variant and hence have a lower growth rate?
This is an interesting point, as we have English (country) names for trees on this site in the English language version rather than American ones, which would be more logical for trees with an American distribution. In this case 'Weymouth' commemorates Captain George Weymouth who first brought the tree to England in the early 17th century but has no relevance to American users of this site. I shan't offer to change the names to the American ones myself as I don't know all of them!
I'd favour using native names (i.e., use Eastern White Pine for Pinus strobus), provided they are botanically accurate (thus use e.g. Lawson's Cypress for Chamaecyparis lawsoniana, and not call it a cedar Cedrus as many in the USA regrettably misidentify it).
I think this tree is Salix caprea (possibly the hybrid Salix x reichartii), rather than Alder Buckthorn. The leaves should be wrinkly above and very finely grey-woolly underneath - very smooth and quite shiny green in Frangula alnus. I'd love to see an Alder Buckthorn with a single trunk more than 30cm thick, but I doubt I ever will! 3.6m girth is also near the maximum size for Salix caprea, though it tends to grow bigger in relatively harsh upland climates like this.
Thank you again (I apologise for my inexperience) but have to start somewhere .. Yes I can see that you are right as I have checked the leaf against picture in Wikipoedia .. Can I change the classification?

The original top has snapped a long time ago, but the tree is still almost 60 m tall. Otherwise the tree is, as far as I remember, in a good shape.
Still more than this tree, I liked neighbouring Olympic National Park. One of the greatest park I have hiked. A primeval wilderness with giant Douglas-firs, Sitka spruces and western redcedars, wild rivers and snow-capped mountains.
