  1. shadowlithing on top of the pierced rock in the Morvan, Burgundy...... .
  2. interesting overview Guy is this US? if so, what's the leaf miner? .
  3. couple of geotropic Fomes on this detached Poplar top from France .
  4. Thanks, glad you found it of interest Nothing new particularly, but a good opportunity to share our experience around managing an important aspect of urban tree populations. .
  5. Ta muchly, glad you liked it Kevin Haven't seen it in the flesh yet .
  6. Good post Marc Interesting it took what seemed like a good length of time before they detached. .
  7. best section has been removed and tethered within the canopy. .
  8. Central timber heavily colonised by the Inonotus which has become fine habitat. .
  9. ash with Perenniporia fraxinea, Ganoderma applanatum & Inonotus hispidus that we are managing down toward a pollard. .
  10. Aurantiporus fissilis - the Greasy bracket .
  11. They may be sphaeroblasts Cell tissue that doesn't form buds and just keeps on deviding and expanding instead. In some species they detach from the trunk. .
  12. Not one of mine Tony as Jerry posted it, but I agree on the tuberaster Id .
  13. another find of the silky rose gill from Suffolk earlier today, this time on beech .
  14. a random discovery of this fine looking sycamore pollard on a roadside in a rural Cambridgeshire village .
  15. Looks good Bit tight for a fiesta though .
  16. Had you seen Jake's presentation to the LTOA seminar on Subsidence from Nov 2012? "subsidence - a tree officer perspective and what we need to do for the future" Also a good over view of Berent v Family Mosaic & LB Islington by Kal Sandhu senior litigation exec You need to log on with your password to access the presentation from the resource section .
  17. If you haven't already it's probably worth your while downloading and having a read of the LTOA's Joint Mitigation Protocol & also the JMP Tree Pruning Criteria, both in relation to subsidence. Downloads | Joint Mitigation Protocol It won't give you every thing you need but should provide additional info on the evidentiary and contacts side of things .
  18. I think Mark has cleared up your misunderstanding of his statement But you bring an interesting point to the table regarding the term 'ruin' I tend to believe that any time an arborist interacts with a trees form we ruin its natural design for our own purposes. Sometimes that can be a good outcome for a tree. But more often than not it's us bending our will on Mother Nature. The majority of the tree population I help manage is urban forest, what I end up inflicting on them (much like the wind, pollution, compaction, climate change, invasive pests and disease & reduction due to demand for space and light) is just another attack and stress on the trees natural biomechanical form. To varying degrees we tend to kid ourselves that we are actually some god like being and can mould a tree to fit our perceptions of how we believe a tree should look and behave. Of course our contemporaries are progressively teaching us how to limit the damage we inflict on them when we make that decision to alter natures adapted design of the tree, but ruin natural design is what we are doing. We alter energy levels, hormone distribution, water and nutrient assimilation, flower and seed production, and inflict wounds on various parts of the tree. So in reply to your question posed to me and the oak tree you referred to above, the answer is................both ! a light ruin and a hard prune Just because my will was bent on taking on natures design for that tree to sate my tree managerial lust and desire for stoping it falling apart and losing habitat, biodiversity and my idea of its aesthetic form in its landscape perspective. .
  19. Resilient things, these trees ! .
  20. White rot on a lightning damaged Horse chestnut by drayads saddle - Polyporus squamosus .
  21. I would say its Turkish hazel - Corylus colurna any nuts on it .
  22. no idea why planted ones can be found in circles, but one of the best examples I've ever seen is at the southern end of Queen Anne's ride at Windsor Great Park they're supposedly 300 years old good panoramic view of it here..... Jubilee Statue - Windsor Great Park, Windsor - Panoramic Earth Virtual Tour .
  23. Any close ups of fruiting bodies? Imo, the fluting would suggest an advanced colonisation of decay. However, I'm managing (reduced) trees with Kretzschmaria that are perfectly healthy from a vascular point of view. Being reduced they are inherently more stable than unreduced. Really depends on target occupancy/frequency and resource for continued monitoring and further management. .
  24. Lightly ruined or lightly pruned .
