Symmetree. We used to have a game at work where you had to think of comedy tree company names. Arbrisk EZTreez - we only do ez treez... Leafull Tree Services

I don't understand the last one. Why aren't they dead?

Don't get me worng. I've got these knives and I love them. But:- They are not easy to open one handed. In fact they're quite difficult. They will slip closed in use as they do not have a locking mechanism. Still, that little serrated orange one is one of my faves

Here's mine. Years of good service! Lives in my coat pocket now http://www.spyderco.com/catalog/details.php?product=13

Its almost like you need some sort of website where they review that sort of software... http://arbtalk.co.uk/forum/showthread.php?t=1521

Eunuch tree services?

Yep as Jay says... click that link, thats what its there for!! Seriously though, sending a form in is the only way you'll get a free ticket to enter the show. It also gives us an idea of how many competitors there will be. I got some of the prizes the other day... I love spending other peoples money!

I'm happy to help out. I'll be the old guy who wanders past all the signs to tell you that "... I used to do a bit o'tree work boy..."

You're damn skippy its arbitrary. The key point in the BS is the bit I highlighted in bold above "...which may change its shape but not reduce its area..." So; take for example the TPO'd x Cupressocyparis leylandii (oh yes!) on a development site I looked at today. Mature specimen tree in the corner of a raised lawn. Corner is formed by two roads. Lets say a 1m dbh for arguements sake (it was bigger and multistemmed) Developers RPA? 12m circle. Shown on the map as including the roads...durrrrr why would the roots opt for road when there is a perfectly good lawn? Well they wouldn't so a more accurate rpa would use the same area of the circle (452m squared) and apply it to the lawn to give a 21 x 21m square. (bye bye to your proposed footed hard surfaced access driveway mate!) But that assumes the roots grow in a square I hear you say. Yep. so lets calculate another way... Its in the corner so maybe its fair to say the roots would have exploited the space in a quarter circle fashion? Seems ok? The guidance says we need the same area so we need to calculate a circle that has four times that area that we want (a quarter remember). 4 x 452 = 1808m squared 1808 / 3.142 = 575 square root of 575 = 24m radius So a quarter circle 24m radius from the tree base out into the lawn. Bloody big but slightly more representative of what the RPA might be. Now apply you knowledge of root morphology. Soil type, species, age obstacles...This particular tree, we might comprimise on a 18-20m radius quarter circle given the vigour and age of the tree and its ability to deal with the loss of area. But don't tell the developer that - he hasn't bothered to do the calculations and I don't work for him! Pete - The 12x modifier is referenced in table 2 of the BS as follows:- "NOTE The 12× multiplier is based on NJUG 10 [9] and published work by Matheny and Clark [10]."

go back to your post, click edit, and 'ave a look.

Paragraphs dude. Makes the rambling easier on the eye. Plus sometimes its better just to run with one good point rather than loads of poor ones... I'd stick with the conservation angle myself...

I hate them. They're absolute ball-locks.

Now you're giving me ideas!! Hmmm Where were those Thuja stumps....

In places. Guy who ringed them was rubbish. Bet he's regretting not learning his tree biology ha ha. We're gonna bust out some grafts.

Done well getting those pines in Andy Nice job mate.

A while back someone mentioned the idea (for better or worse) of ringbarking a tree before a TPO could be placed upon the it to secure a removal. We have recently TPO'ed 10 oaks (as part of a wooland order) in just such a state. They ain't dead. They ain't dying. They ain't dangerous. They are protected! We shall see how it all plays out...

Whoa. Hang on a minute... spy what? Camera or just a tracker? Good god the number of times I slept in the transit through the middle of the day... Rumbled

Mebbe attach them with fabric straps? Great tree mate. Would be nice to mulch that root zone though. (waiting for lee to chip in with some root related specs in a mo...)

I too am in the Sycamore Appreciation Society...

Hey. Each to his own. You like coffee I like coffee Its all good.

Yep, thats the plan. But at the end of the day its a tree, its not symmetrical so it pretty hard to get the placement of the targets right. I'll have to climb each side, time it, adjust it, have a cup of tea, climb it again, time it, adjust it, etc etc All with my nice soft penpushing hands!!! I've set aside a whole day to get it wrong...

Stuff the kelly kettle - you need a Jetboil. http://www.jetboil.com

Ha. Last year everyone had to climb both sides of the tree and have their times averaged! I'm so good to you though, I'm planning on tweaking the tree setup so you won't have to do that!
