  1. Looks a fair bit like Armillaria dysfunction to me. Possibly relatively early on as the canopy is not showing any decline, but the infected sapwood and bark delamination looks like typical symptoms. .
  2. Nice images. Looks to be a good outcome Guy Can you be sure the species of Armillaria back then was one of the more agressive pathogens from the genus or could it have been one with a more benign characteristic ? 8 or so different species of Armillaria in North America, I believe. I ask as we've found what we believed to be the rhizomorphs of the parasite A. mellea turn out (via microscopy) to be A. gallica, which supposedly only kills trees that are already stressed by other biotic or abiotic factors. Was the White oak in significant decline when you first saw it? .
  3. Certainly does the job Stan. Been enjoying fresh coffee all day long at work. Gonna keep one at work and one with my camping gear .
  4. Jeez, using it as a direct injection system for lava java extreme is the bomb ! .
  5. I would think birch if there is no cherry in the vicinity. .
  6. Laetiporous sulphureus at play in this oak volume, enabling tits, squirrels & parakeets to take up residency at various times. Bats as well probably, but nothing at home currently. .
  7. There may be a ticket or two left. Trees: Their Natural History – Peter Thomas | Chelsea Physic Garden .
  8. Kestrel enjoying the perching potential of one of our monoliths .
  9. Its spread across a relatively narrow geographical strip. There are a couple of specimens a little further north than these (on oaks at a neighboring site) that I'm aware of but I haven't picked up on any others going north from here within London. Due south is toward the city center so that's perhaps unlikely to host many/if any Fomes. Conjecture, but these may be the deepest 'found' ones within London from the northern perspective. .
  10. number 10 from today, to add to the distribution map of Fomes on the site. This one found on a dead section having fallen off an oak within open access woodland. .
  11. I thought perhaps you were, I was just being a little puckish Hope it hasn't put anyone off inputting serious discussion .
  12. Looks like a veteran Hawthorn to me, so would tick that category from my perspective. .
  13. No one ever seemed to have cameras back when I was climbing woody type things. Probably due to it being almost pre-digital Here's one of my favourite climbing shots & locations, Portland .
  14. These are a good start..... Fungi on Trees ? An Arborists? Field Guide Smart Phone Apps for Arborists - screenshots both created to be able to be used out in the field .
  15. A consideration may be whether a generic use hire machine would be well maintained and not leak oil on to the root zone. .
  16. 'The office' from a photographers perspective. We're currently doing a bit of work with a wildlife photographer (Matthew Marran) getting him access to some lofty vantage points. Mewp at this stage, but potentialy via rope access later in the year Matt took this at sunset last week toward the City of London from across the tree tops of Hampstead Heath. Needs to be seen expanded to really appreciate it. .
  17. Stem ginger and rhubarb, and very nice it was too .
  18. Really geared up for kids and adults alike. Lots of workshops, demos, music, entertainers, food and drink .
  19. Missed this last year, but managed to get along to Haughley for a few hours today. Yet again the site crew pull off a well planned & enjoyable event .
  20. How tragic, so sad. My heartfelt condolences to Martins family, friends and colleagues. .
