The tree is at Greshams in Holt. (Richard saw us there!) Common name is dead mans fingers... oooh spooky The dead wood bit is the worry. Looks like the tree may have had long strip of necrotic (dead) bark up to this point, more commonly associated with Kreztschmaria (Ustulina). Some of the worst trees in Norfolk at Greshams IMHO.

Its a white rot. I'm not sure of the details. http://www.biology.ed.ac.uk/research/groups/jdeacon/FungalBiology/woodrots.htm

Here's an odd looking thing. Saw this at about 4m up a Beech stem. Its of the Genus Xylaria, either longipes or polymorpha. I've only ever seen it on stumps before as a saprophyte. And the stem showed no other signs of a necrotic material. Bit of a concern don't you think? Oh and its on the tension side of a 30 degree lean into a school carpark!

If you are happy with a short term tree placement then you can plant suitable species as Steve says, depending on the services. But eventually it all gets dug up. Best avoid the conflict - move something. Trees or services... Spend now and save later. Have no idea about containerised trees. You'd have to do an impact study, a risk assessment, a feasibility study, a crossword then write "I take all the blame" 100 times...

Barcham are based at Ely. If memory serves...

A beer later and a bit of reading. In compression wood the cell wall has a helical lignin structure, bit like a wound spring. I'm guessing that once you sever that structure, the ends unwind and fill your cut. As for why it changed back. Er no idea. Don't know the name, but I assume that he's your uncle(?) who works for Mr. Barrell. I'm not in that leauge yet mate... ha one day.
-
So when you put the saw back in, I assume you cut some material away to make the saw fit? There is all kinds of interior tensions and forces within wood, just like vduben was showing in his crack photo. His is a result of deformity of radial tensions. Yours must be longitudinal expansion, as you say probably compression wood. The exact mechanics of it are probably somewhere in my degree notes. I'll get a beer and have a look for you.
-
Not at all. No visible decay present at the stump cut which was about 5 cm off the ground. Little bit of discoloured wood here and there, pretty normal though. Tree had full leaf last year and no foliage at all this year. Pretty fast. Sorry for being sooooo slooooow to reply.

Could be a hickory, Carya spp.

Yeah, crap phone camera can't deal with the sunlight contrast. Definately the beech's favourite Meripilus giganteus root demolition expert! We're preparing a report to support the idea that fungal invasion of this extent and type could be expected to have shown fruiting bodies earlier before the previous report. All worded VERY carefully!!!

I'm at the edge of what I know, but good old wikipedia says... "Depending on the species, Powderpost beetles can feed upon certain hardwoods or softwoods. Some hardwoods are naturally immune, if they have low starch content, or if the pore (vessel) diameters are too small for the female beetle's ovipositor which prevents her from inserting eggs into the substrate. Wood preservatives can be used to treat the wood and prevent beetle infestation. The most common treatment uses boron. Items that can be infested by powderpost beetles include any wooden tools or tool handles, frames, furniture, gun stocks, books, toys, bamboo, flooring, and structural timbers." http://en.wikipedia.org/wiki/Powder_post_beetle Could be a problem...

Nice HighScale, that must have taken you ages! Mondays job - Rig the crown off this copper beech. Client had a pre-purchase tree report done before paying out half a million quid for her house. Then these appeared. Doh. The current thinking is the previous owner removed them before the report. They extend round the entire circumference of the root zone and up to a metre away from the base. Gnarly. Tight dismantle too. But I haven't got any pics of that, as I haven't got the balls to take my camera up the tree!

The larval stages of beetles are notoriously difficult to ID. Best way is to isolate a few affected pieces with larva in a jar with a mesh lid (yeah big jar). Then ID the little critters when they emerge. Wood boring beetles are sometimes best identified by their 'galleries' and the cross section of their tunnels, but those look a bit three-dimensional. Having said that, they can't be too much of a problem in firewood. Probably more of a pest in stored timber. (Unless the emergence of beetles in the living room is going to annoy the customers. I live in a barn, I'm kind of used to bugs and stuff moving in.)

Yep, like the big man said - Hand Arm Vibration Syndrome. Its bad news and made worse by cutting with the grain a with a top-handle. Like most unavoidable hazards the risks can be reduced by implementing appropriate control measures. Like rotating operatives or using bigger saws. When I used to work at the National Trust, we used to winch the tops out of beech trees. Problem was predicting where the failure point would be! Sometimes half the tree would come out or sometimes the tractor winch would stall! The key I think is not necessarily the cut itself but the act of retaining or creating aerial deadwood, which supports a distinct range of organisms. Making it look pretty is just a good way of selling it.

I grant you, Roy wasn't too fussed about the cuts being made from a rope and harness. He was using explosives. I too have done large and small, high and low. It's all in the work positioning. From a good work position there is no reason why a competent climber cannot produce good coronet cuts safely. The vibration and HAVS is what'll get you long before any kickback or rope slicing. So we've taken that into account in our generic risk assessment and H & S policy HAVS screenings. If I spec a coronet on large diameter timber, I add a recommendation that the work be carried out from a MEWP. If the contractor can't be arsed to get one in, not my problem. As for the bugs and the aesthetic. If they mean so little why not refuse ALL coronet cuts???
-
A fortnight ago, I met the guy who brought us the coronet cut. Roy Finch. Define atrocious...

Martyn Honey beating John Turnbull up a rope.

It was worth a try mate. I'll get them onto the 'tube over the weekend. -
I'll take another tomorrow. We cut it in half with a chainsaw but the overall size is still visible.
-
Well sort of. Just found these while looking for something else. They're from last years Arb trade fair. Yes John is footlocking with one arm. Sybs is being assisted by two groundsmen and a pulley system. Martyns just using brute strength... Go Honey 2.mp4 Go Honey 1 .mp4 Go Honey 1 .mp4 Go Honey 2.mp4

This beast's been sitting down our yard for a couple of months. I reckon its the biggest bracket in the world... ...well Norfolk then. I should have stuck something in there for scale but that tub in the back is a two litre spill kit. (Apologies for the amazing camera work.)
-
Yep. Got a Pyrahna S6, little playboat thing. That boat will take a few fivers...
-
I thinks the fungi is probably incidental. The fruiting body you have there looks like the common earthball (Scleroderma citrinum). Here's various pics... http://images.google.co.uk/images?hl=en&q=Scleroderma%20citrinum&cr=countryUK%7CcountryGB&ie=UTF-8&oe=UTF-8&um=1&sa=N&tab=wi As for the poplar... no idea
-
Hey, the bugs and fungi don't care what it looks like. I've destroyed all the photos of my first ones!!!

The customer was Adrian Flux insurance brokers. The head grounds guy just said "...we're a bit worried about that oak falling on the road but we would prefer to keep it, can you do anything with it?" Yep. Always takes a bit of explaining though. Had to tie it in with a lot of other work to justify the MEWP and the time.
-
Heres some I did last month. A lot easier with a MEWP and a 20 inch bar!
