Nice one Thomas.
-
I should add that there was also some tip-dieback at the top of the crown so something's certainly up.

In between buttresses of a large Copper Beech - beneath a pronounced graph line. My initial reaction is immature K.deusta but there is no blue-grey colour on the surface which makes me wonder (and hope) that it may just be a mould developing on the surface. What do you reckon? The host and location certainly fit the bill...

Ironically the google streetview photo of the treee (May 2012) has got the councils contracted arb team parked up across the road!

Oops! Bristol can never be quite as bad as Laandan though. Do you know anything about the tree Stu?

No problem...I had to double-check I wasn't spouting rubbish when you asked:biggrin: I believe lab soil tests can determine bulk density as long as they have a good sample - in order that they can measure the dry-weight of a known volume. I think in practice this means collecting a profile using a tube that needs to be completely full - as sort of explained here: Testing for Bulk Density of Soil | eHow The reason I suggested a lab test rather than a penetrometer was because I assumed this may be less onerous on the college - perhaps easier to collect a core and send it off than find a penetrometer. Perhaps not though?

If you're looking for advice and help setting up a system then I can't recommend the services of James England highly enough. James is an independent GIS expert who has a background in arboriculture and forestry. He has used pretty much every GPS data capture system on the market and has a very good idea of the pros and cons of each. He is also a re-seller for a few of the systems so can supply handhelds and software. I have used his services many times over the last few years and am always very happy with what he can do. His email is [email protected] if you want to get in touch. Apart from that, I have used Digiterra, ArcPad and PocketGIS to do what you are asking - they are all pretty good but excel at different things. The software ranges from £500 to £750 plus the cost of the handheld devices.

Not to mention the additional benefits of water attenuation in the increasingly non-porous urban jungle. As Sloth said, unless there were particular indicators that would raise suspicion of a defect then you wouldn't necessarily recommend a removal. I don't envy surveyors of these large trees in such densely populated areas - I bet they are still required to get a large quota of trees inspected each day (100+?) because of the low £ value placed on this type of work. Even worse if it's sub-contracted out on a low per tree rate. Such large trees in these areas deserve more than 3 minutes of inspection every few years.

Springwatch (Spiking to climb a healthy tree?)
Paul Barton replied to armybloke's topic in Tree health care
To be fair it was a skinny black pine with nice thick bark so I doubt there was alot of damage. Alot less than your average reduction anyway! -
If there have been many years of activity that you'd expect to compact the soil then I'd say that either the soil is pretty sandy so compaction is not becoming a major issue in terms of water percolation, or the tree has sent out roots a long way from the stem so that it is taking its moisture from where it is available. Possibly a combination of both. The way to know if the soil is so compacted that the tree will struggle is to get the soil tested for its bulk density. Send some off to a lab. Mr Shute is a great guy - I'm sure he will help.

How far have you ran/cycled/swam today?
Paul Barton replied to Christopher Schroeter's topic in General chat
Great evening for a ride. Went out with some friends that are fitter than me and did 33 miles including Ankerdine hill twice! -
I saw this tree for the first time just last week as I had a survey job around the corner. It's quite spectacular - I almost crashed the car going round the roundabout. I'd be interested to see the Picus scan image that has apparently condemned this tree.

<p>Hi Chris,</p>
<p>I haven't got your number anymore as it was on my Acorn mobile! Can you send it to me, or give me a call on 07765 493633?</p>
<p>Cheers,</p>
<p>Paul</p>

Ha ha, thanks Stu. Hope you're doing well mate.
-
Yeah a bit! Until recently (in my last job) I spent too much time in an office and not enough time touching trees. My ident suffered pretty badly and I've lost confidence. It's all coming back bit by bit though. Until then I'll have to keep embarrassing myself on here.
-
Cool, thanks. I should go with instinct!
-
Pictures always help!
-
I openly admit to struggling with conifer identification! Can anyone help with an ID for this conifer? It is amongst a stand of Scots Pine and the foliage was way out of reach! My initial thoughts were Douglas Fir or perhaps a Picea species.
-
Also with Plusnet. Shaved quite a bit off our BT bill I seem to recall. I didn't have unlimited package though as we are not downloaders particularly - think all in with a phone package with free evening calls etc it's about £26 a month - it was about £36 with BT.

CA - Pollarding Application - % of height or volume?
Paul Barton replied to adamthearborist's topic in Trees and the Law
It's a little surprising and disappointing that the LA have asked you to state a percentage - these were intentionally done away with in the last revision of BS3998 because of situations like yours. Percentages are open to many forms of interpretation and are not specific enough. If I were you I would reply stating the length of branch material to be removed and the final height of the tree when complete - if possible accompanied by some photos showing where you intend to cut to (it should be obvious for a re-pollard). -
Around these parts it has been the 'Frisia' that have choked it. There was a thread on it before I seem to remember (http://arbtalk.co.uk/forum/tree-health-care/8148-robinia-problem.html). It would be interesting if others of the species also start to die off as well now...hopefully enough to prompt someone to research exactly why it is happening.

What is it?
-
Thanks all for your contributions - it's been helpful. I'm more or less going to stick with how I've been this all along: interpreting the BS recommendations as I see they were intended and explaining my reasoning in the reports....although I may add some more reasoning to make my interpretation clear. The issue for me has been working with another arboriculturist (whom I respect 100%!) that has a slightly different approach. Obviously we'll just need to agree our approach when working on joint projects. As yet none of my planning reports have been scrutinised in an appeal situation - so either I've been doing it reasonably well or I've not had any very contentious sites with determined clients! No doubt my day will come so I'll just make sure that I'm ready for it until then...

Tree Officer - Local Authority? Tree surveying.
Paul Barton replied to Pinkfairy10's topic in Training & education
Good to hear of a planner wanting to improve on tree knowledge! Knowledge is a good thing, and every LA that has a tree warden scheme would like more volunteers I'm sure. Have you tried the Arboricultural Association? http://www.trees.org.uk/training-events/Overview_3 They run a 'arb knowledge' course and a basic tree inspection course which could be ideal for you. I hope you're not put off posting here by the odd replies above. -
How young do you start training them
Paul Barton replied to Dean Lofthouse's topic in Training & education
My boy doing his first clamber.
