  1. A root protection area (RPA) as described by BS5837:2005 is 12 times the diameter of the stem at a height of 1.5m. (or 10 times the diameter just above the basal flare of a multistemmed tree). Similar guidance is offered by NJUG Vol 4 guidelines. Which breaks the root area into zones. I've attached the NJUG guidelines below - they're freely available to download from the NJUG website. The British Standard on the other hand, is a different matter. Has the RPA/zoning been specified for planning reasons or utility work??? NJUG VOL 4.pdf
  2. Just adding to the records... Found 04.03.09 on its eponymous host (in this instance Ulmus procera)at the union of a major limb extending over a busy A-road. A proper inspection perhaps with some decay detection equipment will inform any reduction works.
  3. Too true
  4. If you need a better reason to go Peter, these two have got a bit out of hand... That'll be little old me at the bottom writing the quote for you. It was £250 for 50% off the top right??
  5. You both know exactly what I mean. The topic is timing of tree works in relation to the OPs query about Beech. So if bringing in images - please relate them to the topic rather than invite comments on the standards of work. By the way Dean. The Gestapo would have simply shot you rather than humourously asking you to stay on track. And they would have been paid to do so.
  6. The Curator? Nope, was a saturday though. There was a temporary trail made up with little "Chris says..." signs though!
  7. Stay on topic please or face the terrifying nothingness of the void as I delete a small slither of your life...
  8. Hard day David. Looks tough man. Statutory view? The London Panoramic Vista Act 1926???
  9. And some more... Pinus muricata Cunninghamia lanceolata 'glauca' Abies grandis (Tallest tree on site, known as 'The Old Man of Kent') Random Landscape shot again Some manky old fruiting body on Pinus echinata x rigida - maybe Phaeolus schweinitzii?????
  10. Anyone been?? Brilliant place! A definate remedy for Leyland Cypress fatigue!! Helps that most of the wierd specimens have tags on!!! I lost the light to the end of the day but managed some reasonable shots while the sun was out... The following are: Sequoia sempervirens Landscape shot Picea sitchensis Psuedolarix amabilis Pinus jeffreyi
  11. Ouch. The best novice hasbeen... I have so much to learn from the masters!
  12. And half the price. (?)
  13. That's from the AA's 'Choosing an Arborist leaflet'.
  14. I suppose the history of the consensus stems from Shigo who in turn derived it from Askenasy who faffed about with Russian fruit trees around the turn of the 20th Century. I'd suggest that its fairly reasonable to assume that phenology (the study of the timing of natural events) should be a factor to consider along with all others but as you indicate Marcus - we have to admit we're assuming / inferring quite a lot of facts when doing so.
  15. You ain't wrong. Pick anything living that exhibts a black colouration and you'll find melanin. It's also what gives you a suntan. BTW nice shots Dave.
  16. So will I - but I'm more expensive
  17. Ah but you'll just be pretending to be a washed up hasbeen, whereas I sir , will be the real deal. Oh yes indeedy.
  18. Cool. I can pretend that I'm still in touch with the real world...
  19. However, some seeds do have the requirement of being passed through the digestive system of a bird / mammal before they become 'viable' - scarification. Therefore bird crap is fairly essential in those circumstances!
  20. I think you're probably right with the ID Lancs... Though round this way I'd rarely implicate Stereum as the primary cause of failure, its mostly a secondary decay organism. I'd definately be concerned to see it mid stem though - a certain sign of cambial death and associated dead bark.
  21. Also - now that I have looked at the pics on my laptop and not my teenyweeny phone screen - there's the characteristic cracking of older Phellinus spp. brackets in the second shot.
  22. Hmm could be right. Certainly the classic host for P. tuberculosis. Though the old synonym for Phellinus was Fomes...
  23. Hmmm as one part flexes it pulls/loads another - would that be a good thing? Interesting though - probably destined to stay in the paper and pencil stage IMO. (This is where someone tells me the germans do it all the time...)
  24. I'll try - I was once told that you can't ever say you know something unless you can explain it to a layman. A Mistletoe seed has found itself in a great spot on the Apple - a passing bird crapped it out in the main union and the seed grew using the bird crap as nutrients until it managed to establish a specialised root (called a haustorium) through the bark and into the water carrying vessels and nutrient tubes of the Apple. The Mistletoe then takes what water and nutrients it needs from the Apple without giving anything back (though some think there might be some going back to help keep the host alive). Mistletoe is termed a hemi-parasite because it can produce a little of its own food through photosynthesis (hence the evergreen leaves). In this case I suspect the owners have encouraged the Mistletoe by pruning the Apple a bit too hard and a bit too regularly. That help??
