Unusual bark colour and plating?

[Tony Croft aka hamadryad]

Tony...I gotta tell ya, as per earlier post; I have not seen this before, well. If I had, I did not put it down to this. You should not be so dismissive of your audience...We thick boss!

@ ging "hamadryad, do you take on apprentices? "

Youre fired already mate....Take a walk!

 

I would never knowingly be dismissive, Im just trying to assure that this is correct and you have my word on this, will stake my rep on it! thats all, but I do take these simple observations for granted and it just suprises me sometimes that such mundane everyday observations need explaining!

 

I guess im more suprised that i dont recognise my own knowledge, I still think im a rank ameteur myself! maybe THATS why i come across dismissive of these things sometimes.

 

Were all learners, and each has his/her own contribution to make to any of these forum discussions, but youre right and i must try not to be so qiuck to assume that something is a given.

What scientific explanation do you have for the unusual bark coloration there Tony?

There is no unusual colouration?

 

This tree lives somewhere with reasonable air quality, good epiphytic diversity no doubt, am I so far off?

 

send me the photo full size so i can label all the the parts:001_cool:

the band of uneaten algea is so fine as to be not worth mentioning, the grazing patern is efficient!

 

I tell you what, some people seem to be taking a lot of convincing on this one which i find utterly hillarious, ANY climber will have seen these marks!

 

Thgis aint no mystery, isnt rocket science and if you want to see this for yourself insert a sheet of glass into rain water for a while, till algea cover it then let a couple of snails at it and you will see!

 

Tony, didn't mean to doubt you (and I don't climb so that's my outer) but it just seems too simple an explanation for us mortals. I believe you!

BTW the snails in my fishtanks don't eat that way; they're all over the place!

The snails in your tank are another species, have ample fodder in thier aquatic world and therefore need not be so concerned with the efficiency of grazing, theres food everywhere in their world.

 

Whereas as winter draws in resources become scarce in the wilds and when a source of nutrition is found it must be capitalised on and therefor the extreme nature of the markings, that have even taken (scoured) the outer corky layer of bark as though they had been scrubbed with a brillo pad.

 

Your image is small on the screen so I cant zoom in on it to say too much about whats going on, but take it from me, its not unusual.

I wish I could but you'll have to take my word for it. ( Ive seen it blowm-up but by being logged into a service..sorry)

Its plainly an opaque yellow color...not right for Fraxinus excelsior...wherever it might be!?

Perhaps this is due to the snails ? (ie, slime they use;like slugs! )

perhaps I can...try this link. when it appears (if it appears) my browswer(firefox) allows meto enlarge to 3,000pixels I think....hoping this works!
