Looks more like a rust to me.

Oak leaves are pretty variable aren't they though David and epicormic leaves are more than most!
-
Dean. Acupuncture doesn't work on trees!
-
Did you hear about the accident the other day? Truck full of tortoises crashed headlong into truck full of terrapins. Police said it was a turtle disaster...
-
Why are pirates called pirates? Because they arrrgghhh.

Love this idea. Does the Basic move as freely as the Pantin?
-
At least you had a scapegoat on the pull line in case things went wrong...

Language evolves, pronouciation changes - its communication that matters. If you both understood each other, what's to be gained from moaning about the inflection of a consonant or two? Honestly - and why appeal to righteousness by invoking Oxford??

Andy - as long as the sketch is sufficent to identify the tree being worked on, there shouldn't be a problem. The biggest thing is putting trees on the plan that aren't being worked on! No point drawing one Oak in a line of five! Regards invalidating applications - an incomplete application takes up a lot of officer time and can lead to issues at appeal. We shouldn't have to ask how high the crown lift will be or how much the tree is being reduced by, it should be in the application! My current nightmare is returning forms to people who haven't ticked the boxes in section 8. Uberbureacratic but essential - its those questions about tree hazards /damage that make people acknowledge the reality of their claims.

Perhaps the impact of the twin stems is disrupting vascualr flow? I've seen subordinate limbs with tight included bark unions dieback on Pinus spp. Add in a dry spell and a bit of normal mature tissue dysfunction and your Robert is your Dads brother. Problem with my theory is - its a dead end.

Ha ha cheers David. Game on! I'm liking the Felcos John - No 8s? My vote for winner at the moment has to be Robert S with the mass replant shot! -

My first... -
Indeed. Don't worry though - Allicin can cure everything so a detailed diagnosis is not necessary!
-
That is indeed a graft. The scion has outgrown the stock. IIRC there's some pictures in Lonsdale.
-
Cirrocumulus stratiformis undulatus!
-
Nice - I think I've rambled on this before but the naming of clouds parallels biological nomenclature with a 'genus', 'species' and 'variant/cultivar' style epithets. What you have there is Altocumulus floccus!
-
Could be David, it wouldn't surpise me. The general rule of thumb though is that Oaks within the same subgenera section hybridise in the wild but real effort has to be put in to cross oaks from different sections. Heres a current link... List of Quercus species - Wikipedia, the free encyclopedia
-
IIRC there's some research about this relating to forestry stands (Pine?) - considered to be due to excessive limb swaying and whipping killing terminal buds... Never seen it depicted so well though, its always been a one liner in a dusty book. Nice one!
-
I'm still advocating for the goat hoofed horned one. My point is - no useful information can be produced by this experiment! Lets look at the options; a) Canker gets better b) No change c) Canker gets worse In any of these cases, can we attribute the effect to the cause? No. In order to properly infer causation we need a strong data set, proven statistical correlation and a indication in the confidence of both. One tree is not a trial. What's needed is a systematic, controlled and repeatable experiment that generates enough data to satisfy statistical analysis. Now, don't get me wrong. I appreciate the proactive plant health care you are interested in, I'm just trying to give it all a rough ride. Good science can handle the hardest kickings.

Anyone found this on silver birch
Amelanchier replied to arnoldbuchsassinger's topic in Tree health care
Final instar ladybird larvae probably the Harlequin Harmonia axyridis. Typically where you find the predator you find the prey, perhaps the defoliation is related to aphid infestation? -
Huck has sublimely addressed my reasoning for assuming that you considered the canker terminal! I fail to see what you hope to gain from this... How are you going to assess how the allicin has 'been taken on board by the tree'? What should we expect to see if it is? Localised cankers like that are often compartmentalised - especially within a 10 year timeframe! It would be a fallacy to infer that should the tree survive/improve over the next 10 years that Allicin was the reason. Correlation does not imply causation.
-
Flash mate. Very flash.
-
I hear what your saying there Tommer about the sour taste but I just think that chippers are just plain boring.
-
Just to play devils advocate for a minute - what reason do you have to consider the canker to be terminal?
-
Does being a good climber mean he's a good tree worker??
Amelanchier replied to john@arbtech's topic in General chat
Er... your original post was a reasonable question about whether a climber can be assessed purely on speed. What seems to have happened (much like some of your other posts) is that the responses recieved didn't fulfil your underlying agenda - which in this and other cases seems to be knocking groups of people who you dont like. Resorting to insulting people who don't agree with you does your already weak arguements no favours. Basically, from your posts we can assume that you have a problem with consultants, climbers and the Arb Association. What's the next poll going to be?
