I could not find the thread Tony S started re:NTSG's publication earlier this year. Had I done so, I would post there as this related. We have seen ( hopefullythe back of ) BS8516-Standard for Inspections. We have had a rather unsettling draft document from NTSG. Its a common theme in arboriculture I think you will have to concede. Has anybody seen and/or read this ANSI300- A proposed standard being touted by the ISA ( I think!?) It appears to have highlighted similar issues and some of the same stumbling blocks....? What do you think? A300 (ansi).pdf

I certainly would nt call your postings dull Hama...! Ill bet that "longevity" is the key here. That and the sheer "profusion" of the repoructive process of birch.....! If I had a quid for every birch Ive killed, I d be a millionaire...lol!

Birches also are a dumb "bastard" as Claus would put it. For no reason, they are contorted and bent and twisted etc....It is genetic to some extent I would suggest! As to your comment about "advantage in failure"...consider this...? The problem with that theory...( ahem ..! ) Wood is , as we know, not as strong in compression as it is in tension ( conifers excepted) I am talking now about the pop that Dave posted from usa... The effect of the concertina (cannot spell that one..! ) is actually weaker in compression as a result of this. Have you read the Sterken paper yer Hama. He talks about this , after Mattheck & Breloer... Think about the musical instrument the "squeeze box". It is thus made to make operation less tiring on the muso...in either direction...n'est pas!

Dont know about either system to any great extent. CAVAT however , is designed for trees in the public domain/ownership. The value is there to reflect the tree/s contribution/value in terms of public capital asset....see here for more info.... After our discussion recently re: Cavat vs (a n other system ) I would take the view that the system framework chosen should best reflect the subject criteria. I guess you know that and so are asking about CAVAT.... Hope this pdf helps if you have not read it yet. It also says do not use it without training!! cavat.pdf

This work only reiterates that of Mattheck & Wessolly.....

Have not read this yet as I only just lifted it from UKTC...Looks promising for those who are interested? http://www.isa-arbor.sk/dokumenty/Tree_stability_%20Engels_Peter%20Sterken.pdf Its a free PDF btw (Sterken has been around for a number of years...well respected. )

It was painful watching was n' it! Did you notice his left thumb kept creeping on top of the handle bar..tut tut! 3/10...could do better but dont give him a saw whatever you do!!

Mmmm..David,.you got me there. Im a total novice mate. And then, I observe more honeybees than bumbles. Perhaps a more learned member can shed some light? Males and females are typically quite marked by differences in size. That said, the queen is usually as big as the drone. She will mate with a number of males, in one sitting if you will. This ensures a genetic pool of diversity. The males will attract the female to an "area" for mating as I understand it. Beyond this I am a bit clueless..... You are quite right tho' that there exist, species of "mimic bees". These are entirely parasitic. Food for thought. Thanx 4 posting!

ahh...Lokks like a "taking out the dead" ceremony David....!

I am hoping to not make anything much of a comment but I have known beekeepers take the view that feral colonies are indeed harbingers of disease. I think the point they try to make is that by intervening with anti-varroa treatments, ( and perhaps others) the foothold that these mites get is reduced. Much like trees, once weakened (by the varroa mite,) viruses are quick to capitalise, exploiting their hosts in a myriad of ways!! It should be said that many of the symptoms that beekeepers observe are not well understood. It is also true to say that honey bees are only an aspect of the bee kingdom which, whilst at risk from low numbers ( for whatever reasons) is rich with a diverse range of bee species.... Good thread ....I hope you get the situation successfully resolved!

You need to remember that the successful overwintering of a queen is a part of a lifecycle. Failures and interruptions to this process inevitably weaken the resources with which this process occurs. This is just FYI but to assume it will all be good on the basis that they all die anyway ( bar 1 ) is to misunderstand the fragile equilibrium of said lifecycle.... cheers.

Sweet hispidus pics Tony...they are very visual.

No...Innonotus dryadeus is not known for it's alacrity. You should have more faith in the impressive systemic and genetic strengths of Quercus robur (imo) In have fallen foul of folk in a similar thread regarding this fungus...I would stand by my comments though. A tentative root investigation only makes sense if you are aware of what exactly you are looking for...in this regard, can I suggest referring to "Fungal Strategies of Wood Decay in Trees" (Engels, mattheck, Scwarze).... Im not convinced of the value of picus below ground ( and at flare it needs caliper...) What target occupation/value have you assessed this as being? I agree, we cant save every tree but your comments are premature....!

Cool...I remember "Plantscape" when it was just starting out in 1997 (ish ) It was all interior plants back then IIRC ? -
Yeah, they dig the vibrations of the saws apparently.....I have heard stories of bees on the other hand trying to sting the exhausts of strimmers....Food for thought? Steve...If you know of ANY legislation that protects bees in the uk, I would real like to be made aware of it...?

Bumble bees preferred habitat is the ground....thats your luck I guess! If you can relocate the nest/hive, you might be successful in moving them elswhere. Lowering to the ground and continue the job maybe. There's always a risk they will disperse and the colony will die . Leaving them is best eh! If you can. You are right. There is no protection afforded these insects. Indirectly perhaps by way of spraying regs and restrictions but otherwise nothing I understand.....Im afraid you are the front line!

Tree preservation orders announcement
Bundle 2 replied to David Humphries's topic in Trees and the Law
"Yes it does. You're oversimplifying the value issue again - what about the tree that has amenity value but just not enough to TPO it? Is it OK if the owner wants to top it at 6metres because it blocks the TV signal? You suggest creating the same wrangling and informal dialogue that goes on already in conservation areas ..." i would n't know about the wrangling ( ! as if..) but this is the point I was trying to make.... "No, not one that reduces workload whilst increasing protection. " That would be good. Even one that managed to increase/improve protection without significantly increasing workload. And mostly because trees are undervalued ( its a perception thing) we need to come up with a wee bit of magic! -

Bundle 2 replied to David Humphries's topic in Trees and the Law
There is also a point in here I tend to agree with. Whilst replanting (& equally, new planting) is a significant issue. ( ie, we need more ) I tend also to think that canopy cover, perhaps in more general terms, needs some degree of recognition, perhaps above and beyond requiring it to meet a level that would be considered acceptable for a TPO. This is an important point We need to start valuing/measuring/appraising our trees as a part, inextricably, of infrastructure in the wider sense..both urban and rural. -

Point taken...It seems to go hand in hand with site visits though surely. You cannot become acquainted with a district ( to whatever degree) without in some way viewing that district? "Have you ever worked as a TO Bundle?"-No. Its a job I would like to have some experience of . -

":There would be no paperwork for most trees - the notification comes in, as TO you already know the area (and possibly even the tree)..." This is not a realistic reflection of the situation either imo ....! -
Very cheap units from Maplins produce very small current. They will not recharge a battery but can maintain a healthy cell/battery whilst not in use indefinitely. Folk I have spoken with claim they are good for winter months. I have no personal experience of this. Cold crank amps vary battery to battery as Im sure you know..I have kept sealed units charged with such a unit...Hope it helps!

Morpeth...beautiful place....just come through there. Plenty speed cameras in your part of the world eh!
