Clonal trees are much harder to date than single trees because there is no single set of rings to count. You can count the largest stem rings but in many cases as climates have changed then all the stems may have burned down but the root mass allowed the tree to regrow before competition or when it is too dry to sprout from seed.

Some species may allow core drills while others may die with that intervention. If there are similar trees, the girth of a dead tree of the same species may allow an informed estimate when rings are counted.
