  1. I will vouch for Charlie as being a decent bloke that runs a good outfit! I am sure he would be a great person to work for.
  2. Good evening all. I am looking for an experienced arboricultural consultant to join our team at Barton Hyett Associates. We are currently based in Worcestershire but are re-locating to a larger rural office in Gloucestershire (near Northleach) in September. Our work is a mix of planning/development related tree surveys, tree condition and risk surveys for rural estates, schools, universities etc, and detailed tree assessments using tomography, resistance drilling etc. We are a friendly, easy-going but hard working team and there appears to be lots of work on the horizon so we are on the lookout for a highly-skilled consultant to grow their career with us. We are offering a competitive salary (likely £30-35k but will depend on the calibre of the right person!), company pension scheme, CPD programme and flexible working arrangements. You can read more about the role here, or if you'd like to speak to me about it send me a message with your number and I will call you back.
  3. I used to work with Josh a fair bit when I was on the tools and in Bristol. I can vouch for him being a top bloke 😁
  4. There's a handy new app available on Android and iOS developed by Tim Moya Associates. Search for 'TMA fungi' and it should appear in the Google play store / Apple App store.
  5. Anyone tried the 'Itiwit' inflatable kayaks from Decathlon? They look pretty good. https://www.decathlon.co.uk/2-man-inflatable-kayak-2017-green-id_8387561.html
  6. It's easy to call them whingers but if they are retired people that want to sit out and enjoy their garden then the shade cast by these trees is a genuine 'dis-benefit' to them. I can see why the tree officer won't cut them down as this could set a precedent for other people that back on to other trees along this road. And a reduction would be pointless as the crown density would be the same in a year or two. Maybe the council could agree to the works if the complainants are willing to pay for the felling and replacement planting of a new tree?
  7. Forgot to say, I also now mostly label up the topo plan on the iPad too using an app called DWG Fastview. It works pretty well so no more paper flapping about on a clipboard!
  8. Hi Nathan, If you haven’t already, it would be worth searching the forum for old threads about this. As you may already know, there are some off the shelf package softwares that will enable you to do what you need but it depends on the output you require - I.e a CAD plan or an Excel spreadsheet etc. I just use an iPad with a pre-formatted spreadsheet in Numbers and then send that to my CAD technician with a copy of a marked up topo plan. Check out Pear Technology software for an alternative.
  9. It’ll only take 10 mins to appeal for non-determination.
  10. Fantastic! Loved having a fly about on the 3D model. The resolution of the main stem and branch framework seems pretty good. What’s the minimum diameter of twigs picked up? Love the black and white photo of the trees before they were enclosed by the woodland - another reminder that tree time blows my perception of time out of the water! What do you see as the key uses for this kind of technology David?
  11. Good point Gary, but I think he is saying that as the surveyors for this CAVAT report were non-arb trained volunteers, instead of expecting them to make a sound judgment he just applied standard depreciations. It's quite a broad-brushed approach that obviously limits the confidence in the final valuations given. However, as a starter for ten using a respected published method, it's not bad.
  12. Congratulations. What's the role?
  13. I’d have a stab at Phaeolus schweinitzii
  14. Top class reply Julian! One thing about the 'RPA' is that is not intended to necessarily represent the extent of roots. Although I see some logic in the root:shoot ratio theory, it doesn't allow for those roots that perhaps by necessity due to soil conditions, track an awfully long way from the stem in order to exploit available soil moisture. I.e. if the soil in close proximity is moist and nutritious then the tree may have a fairly compact and fibrous root morphology, but if conditions are not so good a tree will throw out exploratory roots for some distance. We've all seen roots tracking under roads and footpaths etc. So if the RPA can't even come close to describing the radial spread of roots, it must be more about a sufficient volume of soil that is required to sustain the tree. As Julian says, this means that soil depth is pretty critical. If the soil is only 50cm deep before rock, then we should all be doubling the radius of RPAs as I recall the BS5837 radial RPA is based on a 1m depth! Going back to the original question, is it reasonable to estimate that a pollarded tree will need less soil volume than a full-crowned tree. Well, yes I think it is but perhaps only temporarily as pollards tend to produce prolific foliage to re-instate the root-shoot ratio. Research in to heavy pruning/pollarding to reduce water demand in subsidence prone areas shows that water uptake is resumed to previous levels in just two-three years after cutting so unless a tree is pollarded very frequently to control it, presumably root activity continues. Julian - your observations about incremental thickening of pollards is very interesting. I don't have any stumps or cross-sections to dispute your point, but I do recall hearing a talk a few years ago from Mr Barrell where he showed some slides of some small pollards in a church yard - the assumption was they were quite young as their stems were slender but when they were felled they were found to be really quite old. Maybe a long-term regime of pollarding does reduce incremental thickening? Or maybe those trees were just growing in poor soils and had somehow struggled on for more than a century!
