Dendrochronology is a measure of climate and this is only accurate for working out the age of a tree if the climate is the same year in year out this means it is highly probable in temperate climates a ring = a year, but it is also true that in tropical climates it is a record how many times a tree flushed and this can be two and three times a year.
I will go 400 years just to be different from the rest of you
yeah reading rings is not as easy as 1 2 3 but as this log is green not dry which can help define rings and its from southern OZ it may just allow dear Stihlman to get a close enuff estimate of numbers,,,, er um that's if he can count that high,,,, sir you may need to take yer boots off or bring a blackboard n chalk lad :msp_biggrin:
you can often see past years eg 73 & 81 of drought and plenty 84 & 96-98 show in the rings as good or poor times
The oldest I soxed was 350 old red gum and it was a stupid act cuz I though was decayed and dodgy over a school yard but once down it was only rot on trunk surface and Codit had held it firm. That tree could still be there 200 plus years if I known better.
