    Most of the research into ‘Tree Architecture’ (Arboritecture) is from France and Canada.  That means it’s published in French, which many of us can’t read. This piece by Tom Joye, in the UK’s Arboricultural Association’s Arb Magazine, is a great introduction to the world of Tree Architecture, and what it can reveal about the ‘development stage’ of a tree.  It’ll have you look at growth and epicormic growth in a different way.

    The Coroner’s findings into the death of Brendan Smith from a tree falling onto a Tasmanian highway is one of the reasons I’m about to head out there - along with running tree risk training workshops and some work with government agencies in Australia and New Zealand.

    Australia’s ‘Arbor Age’ magazine have recently published ‘Death on the Highway’, which is a piece about the findings and the importance of having a robust Tree Risk-Benefit Management Strategy.  Below is a grab of the first page.

    Every summer, when we get long hot dry periods, concern is often raised about the risk from Summer Branch Drop (SBD).  Fear not.  We’ve got the risk management of SBD covered for you in our free Summer Branch Drop Note.


    In brief, the overall risk from SBD is mind-boggling low.  What that means is there’s no need to fret about putting up signs, or fencing, or pruning, unless you have a tree that’s a repeat offender.

    Have a look at our Risk Management page for lots more free and handy tree risk management advice and help.

    To make good decisions (about tree risk) means that we have to have confidence in what we do know and what we don't know.  This double-header about confidence is a great listen from the BBC World Service.

    It's probably not much of surprise to find out there's very little overlap between confidence and competence; how good people think they are, and how good they really are.

    Confidence: Why it misleads us

    But confidence can also be a force for good.  Here's how.

    When a tree might be 'dangerous'*, it'll usually have obvious defects that you can't help but notice.

    To help you spot trees that might be dangerous, here's an illustrated Obvious Tree Risk Features guide or you to download.  We're more than happy for you to share it around.

    *Dangerous = where the risk is not acceptable or tolerable.
