    Tree ID please guys

    Alnus cordata? Italian alder
  2. Nonsense! You can't anthropomorphise the relationship between trees and fungi, and can't reduce it to 'good' guys and 'bad' guys... Trees and decay fungi have evolved together over millennia, and while it is disappointing to lose individual valuable trees to the likes of Ganoderma (and as a TO I've lost a few on my patch) there's no point getting hysterical about it. Incidentally, the '87 hurricane was a lightbulb moment for arboriculture, when it was realised that hollowed trees were more resilient to windblow than non-decayed stems.
  3. Eh??? Why would anyone want to make Ganoderma extinct? Have we learned nothing regarding the complex relationship between trees and wood decaying fungi in the last 20 years?

    Mycorrhizal development from scratch

    Anybody got any ideas on how long it will take for a functional mycorrhizal community to develop naturally on a new tree planting site on what was formerly a landfill, rough grazing and amenity grassland. Are we talking years or decades, and what can be practically be done to speed up the process?

    Alder ID

    Yes! Looks like it. Planted by Aberdeen Council on the edge of a common 25 years ago, small group. Thanks.

    Alder ID

    Can anyone help with this alder id? I'm familiar with black, grey, red, green, italian and sitka but this doesn't fit the bill with any of them. Closest to Italian in jizz but leaves are massive (25x11cm), almost hairless and uneven at base rather than cordate. Thanks

    6 week limit in CA

    Sounds like what I was thinking. Thanks for that, Paul.

    6 week limit in CA

    Hi all, Some basic dumbarse questions I hope you can help me with: Am I right in believing that the only recourse a LA can have to stop treework being carried in a Conservation Area is to put on a TPO before the end of 6 weeks after receiving a notice of intent describing the work? Or do they have other powers to stop work? Also, if a LA requests clarification or further info, does the 6 weeks period start again?

    Genetically Driven Bad Crotches

    Went to Duncan Slater's Fork workshop in Edinburgh a couple of days ago. His research shows that 93% of unions with included bark are associated with strain being removed from the branch by mechanical bracing further up the branch, such as by crossing or rubbing branches, at some point in time. So trees with a naturally dense and tangled crown, such as whitebeams or hornbeams for example, or fastigiate cultivars of many sp. have a genetic predisposition to 'bad crotches'.

    Tree ID practice

    Damn, only just caught up with thread... Could have astounded aabody by saying Toona sinensis (but that would have been based on your earlier reference to surveying Glasgow Botanics rather than any sublime id skills!!).

    Tree ID practice

    I'd go with Nothofagus obliqua on this one based on form (fairly distinctive), bark (grey with horizontal plates) and most importantly leaf (veins reach the margin between the points as opposed to at the points in Zelkova.)
  12. Do the beetles wait for height or is it maturity? Dredging my memory of lectures 20 years ago, I think the beetles find trees of a suitable height, where they feed in the leaf axils on twigs in the crown, infecting the phloem with the fungal spores picked up from the dead wood in which they hatched. The infection then progresses up the branches and eventually into the trunk aided by the trees own nutrient transportation system, leaving dead branches and a 'stag-headed' look to the crown. Debarking any felled infected timber will deprive beetles of egg-laying sites.

    tree planting

    Type of nusery stock (ie bare-root or plugs), stock size and planting method (if specified) also a consideration....

    Dying elm trees.

    Although, as various folk commented, DED aint going away, you can do your bit for hygeine by debarking any timber left lying about or sold.
