Roundwood weight difference when sap has risen?

[arboriculturist]

I have heard conflicting views about the difference in the weight between freshly felled Roundwood when the sap has risen compared to when trees are felled when dormant.

 

One bloke said he had 10% less volume on an 8 wheeler load of Sycamore felled in June compared with the same in December.

 

It appears that individual tree species vary a lot also.

 

Would anyone care to comment or put a % on the difference?

volume has got nothing to do with it...

 

 

when the sap has risen it will undoubtedly be heavier but there must be so many variables that could change the percentage is there any point trying to work it out.

I think what the bloke meant is: e.g. The 1 summer felled load he processed into logs he got 36 m3. The 1 winter felled load he processed into logs he got 40 m3.

why what is in the wood instead of sap? Consider how fast felled sycamore loses water in the summer.
