    Football eh, bloody hell!

    Been a Spurs fan since the eighties and have been to a couple of cup finals with them (best being ‘91 FA cup) but still coming to terms with how the actual fuch they are in the biggest club competition in world football. Poch is a pretty good gaffer and there are a few pretty decent players in that squad but Champions League Final?!? Been a great run from the lilywhites. Liverpools result was epic too, really enjoyed that piece of theatre. Uefa not gonna like having ‘potentially’ 4 English finalists in their two cup competitions. Suspect we will see a change in the EPL coefficient in the next couple of years.

    "That" Nottingham Walnut tree

    Sorry to hear of your hassle. Totally undeserved, unmerited and unwarranted, I sympathise with you. Social media and public reaction to tree work is an absolute disgrace at times and full of ignorant uneducated and ill informed fools. Sadly stoked by very poorly managed public trees like the Sheffield debacle and privately owned trees like on development sites which are getting netted. That can only change by a continued line of education and information to the public as to what’s happening to the trees and why. (Planning notifications etc..) People like trees and all the good they do us at a conscious and subconsciously level and get upset when what they see those trees disappear from their treescape, often not replaced. Playing the advocate of the one that should not be named, had the tree had any structural survey before being condemned? Yes it is significantly decayed, (it appears quite hollow in the stem) oddly enough trees actually go through that process in their lifespan and can remain standing and even leaning like that for many decades. How were the roots and trunk base? Your original picture ‘appears’ to show a vascularly healthy tree with full canopy and buds and also strong vital active outer sapwood layer. Had any consideration been given to reduce the tree to help mitigate the ‘potential’ risk of collapse? I think I’d be disappointed if I had that tree in a neighbouring garden and it got taken down.

    Tropical Canopy Access Odyssey

    Excellent, thanks for taking the time to share Rob, looked like an inspiring trip.
  6. Slightly different machine and I’m coming from the local authority perspective so don’t pay for the calibration out of my own pocket, but do have to justify the annual cost of calibration to senior management. The PD series flashes up that it requires calibration after a thousand drills or a callender year, which ever comes first. (Usually the latter for us) We use the Resi PD400 a fair bit and the graphs do go in to reports for where we are condemning or retaining a tree. Having an in date calibration certificate as an appendix to a report gives the report more weight in my opinion. Also gives us confidence in knowing the motors are being looked at and service where necessary. I would think from your perspective (as you’ve already alluded to) it will depend on how often you utilise it as a tool.

    Self Bracing

    Suspect this beech union would fail if one or both of these natural braces were compromised. Would be fascinating to sever one and see how long the union withstood the load.

    An easy one

    Great edit Reg, an easy watch. Particularly like the reflection of the stick falling in the window @ 2:50 and the cat running away ! What makes you choose the battery topper for the stripping?

    Decay images

    Poked it a few times over a number of years, so had a good idea of the level of decay.

    Decay images

    I've posted this Red Oak before (evidence of both Ganoderma resinaceum & Ganoderma australe) but on passing today it was worth noting the decay process over the two years since it was felled. It appears that the reaction boundaries between the two decay zones of the G. resinaceum and G. australe colonies still remain quite lignified.
