    On account of the UK environment finally waking up after a short restless sleep I propose a competition. Best spring related / themed photo. The normal rules apply: Trees should feature - pictures of newborn lambs skipping through daffodils will not win. Maximum three photos per entrant. All entries to be posted in this thread. No cheating (we can tell). Monkeyd can't win. The winning shots will be picked by the Arbtalk Arts and Culture committee on the 30th April. First and second place will recieve a copy of 'Trees and how to grow them' produced by the Tree Council. Plus the lifelong admiration of fellow Arbs. If we remember, we'll have a think about a third prize. Get snapping.

    11? Where'd you get that from??? You right that you may offset the RPA of an open grown tree by up to 20% in accordance with BS5837:2005 but there is no provision for offsetting a NJUG zone. That's because one is a planning tool and the other a mitigation guideline. I interpret 'open' as meaning there was nothing to impede the growth of the tree above or below ground. That includes other trees!

    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

    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.

    Too true

    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??

    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.

    The Curator? Nope, was a saturday though. There was a temporary trail made up with little "Chris says..." signs though!

    Stay on topic please or face the terrifying nothingness of the void as I delete a small slither of your life...

    Hard day David. Looks tough man. Statutory view? The London Panoramic Vista Act 1926???

    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?????

    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

    Ouch. The best novice hasbeen... I have so much to learn from the masters!
  14. Amelanchier
    And half the price. (?)

    That's from the AA's 'Choosing an Arborist leaflet'.

    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.

    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.
  18. Amelanchier
    So will I - but I'm more expensive
  19. Amelanchier
    Ah but you'll just be pretending to be a washed up hasbeen, whereas I sir , will be the real deal. Oh yes indeedy.
  20. Amelanchier
    Cool. I can pretend that I'm still in touch with the real world...
  21. Amelanchier
    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!

    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.
  24. Amelanchier
    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.
  25. Amelanchier
    Hmm could be right. Certainly the classic host for P. tuberculosis. Though the old synonym for Phellinus was Fomes...
