  1. You haven't seen the Chinese copies then? Bloke in a van was touting them around last week.
  2. You keep telling people to F off probably don't help!
  3. You could possibly justify it's retention with a smaller crown after some testing, but realistically there looks to be large trees surrounding it, so would its loss be that significant?
  4. What's the targets? I've dismantled sycamores with very little live canopy, with KD, and was surprised how sound the stem was.
  5. Just watch him with those cyclists on sunday!
  6. Yeah, you're right. I wasn't thinking about two strokes specifically, just something I though I knew about engines generally - Forget I said anything.
  7. I've always understood that the most wear to an engine occurs when it's started from cold, before oil pressure is reached and everything is coated/lubricated. Would your practice actually cause premature wear? Just musing on this..
  8. I thought they were to prevent recreational climbing?
  9. And today's cheery thought is...
  10. Not arguing about numbers, just thinking about how China's laws were originally perceived as draconian when in reality they probably weren't such a bad idea.
  11. China's one child rule doesn't actually seem that daft when you consider it.
  12. It would benefit me! But I know what you mean.
  13. I'd be more concerned that they were recording you!
  14. That's not overloaded, the boot's empty and the front seat passenger hasn't got a bucket of clay on their lap.
  15. Unless the tomograph is showing a very narrow residual sound wall, the final management recommendation can vary considerably. Lots of factors should be considered, such as the surrounding targets (people/vehicles/structures), as well as the environmental, social, economic benefits that the tree provides. As you say, decay isn't unusual in old trees, but removal isn't always the only option. Testing only provides information, as to the extent of decay at the positions tested, that information has to be interpreted and you should be provided with a number of options for future management, with the benefits/disbenefits of each. It's not really up to the arboriculturist to tell you what to do, but provide the information for 'someone' to reach a balanced, educated decision. What are the ongoing management costs for?
  16. Picus doesn't pick up decay by Kretzschmaria deusta, unless I believe it's very advanced. Otherwise it's pretty reliable. Bare in mind that one scan is only one cross sectional plane view at the location, the more scans the better to build up a better interpretation of what's going on.
  17. Have you any pictures of the whole tree? The dieback in the crown (to one side) is probably due to the break in vascular connectivity due to the damage at the base. The other side of the crown remains unaffected so continues to grow.
  18. A consultant can undertake a safety assessment. A basic/stage one assessment is from ground level, looking at the body language of the tree - if and how it has adapted to external stresses as well as internal dysfunction or decay. This assessment may trigger more in depth investigations - a climbing inspection to look at cavities, fungal fruit bodies at height or invasive testing such as a Picus test or some drilling with a resistograph. Just because the tree has lost a limb doesn't necessarily mean that there is any great problem. The failure may have been caused by localised decay, maybe where a limb had been removed previously, decay in that area started and eventually the load of the limb overcame the strength of the remaining sound wood. This is what the assessment will be looking to establish. Whatever else is observed will guide what, if anything happens next.
