Sycamore tree and extent of root system

[Pearly]

Please could anyone advise of the extent of the root system on a mature sycamore tree both in terms of depth and also in width extent?  Many thanks.

Example here so will be similar extent versus the tree top.

I would say it will be massively dependent on soil type, water availability, wind, other vegetation and other factors.

Root protection areas are estimated are roughly circular with a radius approx 12 x the diameter of the trunk at breast height (DBH).  It's only guide and as others have said will be affected by other factors (rooting environment, obstacles etc).  But it will give you an approximate idea of root spread (not depth though).

What's the reason for the question? It might help get slightly more detailed answers.
