Mystery horizontal lines on trees

[GBW]

Could this be the work of gliding possums who make incisions in trees to extract sap?

No.

Well I'm glad we got that straight

That's an intriguing theory but I think our possums are rather too heavy to glide between trees
Can't quite see how they would manage to operate so accurately at the same distance from the ground either.
Looks like it's time to try finding an appropriate entomologist again. Aren't there any on the forum?

Sugar gliders? Squirrel gliders? Feathertail gliders?

They are not a mystery,only if you want them to be..............

Don't have any of them down here [/quote] Soooo.......,the mystery is created.........what about sabre tooth tigers sharpening their teeth on trees??...stupid ?...far fetched ??...yep.....still plausible.....

I trust looking at the time of your post some potent liquid encouragement may be helping your post EH!!

Sugar gliders are found in Tassie. Not that I'm saying the marks on the tree are caused by gliders. I still think it's caused by a grub.

Sorry forgot about them as an introduced species doubt that there are prevalent tho .

I think you maybe neglected to finish your last post ,corvus ?........what were you saying about liquid refreshment ?........

[Chris]

Yes sorry, me too though don't believe squirrel or feathertail gliders have reached us yet.
Still fairly convinced about the grub theory, but the consistent horizontal pattern is intriguing.

I promise not to nick your grog !! unless it is in an unbreakable glass exact copy of mine which I did at Wadley's to flyfisher several years ago

Sorry Chris. When I posted about the gliders I didn't realize it was in the Tassie forum. I thought you meant possums in general (Aust. wide) were too heavy to glide. You are correct though - squirrel and feathertail gliders aren't found in Tassie.

Thanks Corvus - I didn't know that sugar gliders are (thought to be) introduced to Tassie. You learn something every day .

I love these convoluted threads...

Neither did I until a few months ago Vicrev. Just to extend the convoluted thread briefly apparently they are attacking our endangered swift parrots - eating nestlings and even sitting parents in the nest.

Very true Corvus. When I said Hey that's my grog, you looked at it, agreed, drank it quickly down and handed back my EMPTY glass.

We used to shoot Beer Bandits once upon a time, before we became the Nanny State .....sorry, off topic..

Here's a photo of a street tree, I think E. rubida, in Aranda Canberra that has been heavily attached by beetles that leave the distinct horizontal axe chop marks:
