why do oaks drop twigs

[David Humphries]

John, I've picked up the abscission theory from Ted Green & Nev Fay, who know a fellow who is actually going around each year and literally counting every single dropped twig on a specific Oak, to try and quantify and evaluate the idea.

It may even have something to do with the possible symbiotic relationship between old trees and nesting woodland birds, nesting material and the likes.

A little bit too left field for most of us that one I'm guessing

 

Some people just have far too much time on their hands, I believe this one may be German

In a thousand years time trees will develope brains and defense stratergies against scottish tree cutters

 

well all they have to do is ask for a little rain and they are safe from the yorkshire ones:lol:

ooouch, that hurt me Stevie, very hurtful mate, BUT TRUE

I think we're talking here about abscission twigs.

 

Particularly, It is thought that Oak does this as a form of self biannual fertilisation.

 

In a natural surrounding, if left, they break down and add the nutrients back into the Rhizosphere.

thanks dave, think the old chap might like the possible sybiotic relationship with birds theory as hes a bit of a twitcher

Ain't Trees just groovy

 

Nipped outside to a petrea and collected a random sample of Abscission twigs from under the canopy.

 

Note the neatly formed calous, which I imagine swells to detachment upon the Trees reaction to local environmental conditions, drought, pest etc

 

Thought it of interest that the last shot shows three different states of morphology, with leaf, without buds and with buds.

 

Didn't find the corresponding abscission pads on the Tree (like in the picture in Tims link) as it's raining & I don't do wet at the weekends

David was telling us about some mad German who collects twigs, HE then went out and collected twigs

 

What I want to know is if the tree is dropping twigs for the birds and he comes along and STEALS them, how can he call himself a conservationist!!

[David Humphries]

At great peril to myself, I braved the rain and replaced said examples in almost the same location as were found.

 

I believe that no future avian generations were hurt in this little AT experiment

 

 

 

I'm like a stick of rock me Dave, cut me inhalf and I'm green all the way through.........honest
