I'm starting here at the very beginning of dendrochronology, but wish to eventually create a 5-600 year old (minimum) English Oak reference curve that is scientifically valid.
So, at the very beginning I shall start...boring holes into living trees, as advised! I have emailed Haglöf for advise and prices on their increment borers for large oaks. There are more oaks in Bath (where I live) in excess of 2.5mtr diameter than I can count, so feel these to be invaluable sources of data if I can get at it...they do sell 1000mm borers (would they most likely get jammed at those depths in an old oak?).
Am I being too ambitious thinking I can access the inner most rings of these great trees with an increment borer? Has anybody any advice? How deep can you realistically bore into a living oak?
Many thanks for all the private emailing help I have had so far,
