Just need to post this somewhere! I ordered a custom frame bag on the 2nd Jan from my bike and recieved it today. Hand made in the UK, perfect fit, great service (they called to confirm measurements), prompt turnaround and delivery updates. Awesome. Can't recommend them enough.

You've just cherry picked one small component, missed the wider implications and beautifully illustrated my point. Thank you.

A handful of videos aren't sufficient evidence to infer the wider safety of anything. In stats there's an error known as the Texas sharpshooter fallacy. Guy shoots randomly at a barn then walks over and paints a target around the closest cluster of holes and claims to be a sharpshooter. We have no way of knowing if your videos are just a target painted after the fact. We never will have and actually neither will you. Add natural overconfidence and brace for deadlock.

Wow. They're stuffed if that doesn't get moved promptly and delicately.

The literature has a knack of doing that... http://arbtalk.co.uk/forum/general-chat/29796-weeping-willow-too-close-house-3.html#post485286 Perhaps its the institutional failure to publish negative or plainly intuitive results; but perhaps trees are just expressing Orgel's second rule?

Ha - the virtual library is dust free!

Clearly not relevant to the OP but depending on soil type or compaction, some trees appear to be able to tolerate up to 200mm of fill over the root system. Day et el 1999_Overlaying_Compacted_Fill.pdf

What do pages 131-132 say?

Before that I would check that they haven't been measuring in cubic feet and charging by cubic metre... It happens!

You could take the existing TM ring off and girth hitch it to the middle of the bridge. Krab would be orientated differently but you wouldn't be adding any parts to the system.

Yes

Russell, Have you considered instructing an arb to give you a formal opinion? These kinds of things are best done first hand.

Could also possibly be a stem gall caused by Rhizobium radiobacter (syn. Agrobacterium tumefaciens). Either way, not structural issue - just looks weird!

I can't imagine...

Wonder what a whole set in good condition is worth?

I doubt you'll see a reprint anytime soon.

The author mentioned above (Clive Mayhew) also wrote a paper on using various clues to infer introduction dates in the field. Mayhew, C. (2009) A technique to help arboriculturists understand the sequential nature of tree introductions into historic landscapes. Arboricultural Journal: The International Journal of Urban Forestry. Volume 32, Issue 1, 2009 He identifies eleven distinct periods of introduction based on on the timeline of discovery, exploration and trade with the rest of the world by europeans. So for example the arrival of antipodean species such as Cordyline australis correpond with a period started by the return of Joseph Banks & Captain Cook from the southern hemisphere approximately between 1772 - 1820 (Mayhew's period 7). It couldn't have got here any earlier because no-one (no-thing) had had the capacity or willing to bring plants back from that distance before. So if you know the regional origin of a species and also when that region was discovered / explored / pillaged then you can have a pretty good guess of the timeline of introduction.

I have one from the AA "Designing with trees" course at Kew but I'd better check with the author before releasing it into the wild.

Five days.

One of them should have been an arboriculturalist...

Some decent sensible points there - I'm glad we've got away from the idea that QTRA is purposefully deceptive.

Well cheers for the title but I can't agree there either. Maths isn't a strong point. As far as I see, not understanding something isn't an excuse to dismiss or demonise it. I'm happy to move on to colour spectrums They are more interesting.

Ouch. So how do you describe the risk with words? High, medium, low?

True, but I just read all the threads on the QTRA forum and wanted you to find one that supported your point because as far as I can see - there isn't one!

Ah that'd be telling...
