A recent attempt to use tree ring analysis on olive trees (Cherubini and colleagues) revealed that too much variation of the cambium occurs in olives to make dendrochronology viable.
That study was one of ongoing attempts to determine a reliable chronology of the Mediterranean Bronze Age.
Results of carbon-14 dating are reported in radiocarbon years, and calibration is needed to convert radiocarbon years into calendar years.

Trees in arctic, sub-arctic and alpine regions respond differently depending on how old the tree is--older trees have reduced water efficiency which results in a reduced response to temperature changes.Features such as wood density, the elemental composition (called dendrochemistry) of its makeup, the anatomical features of the wood, and stable isotopes captured within its cells have been used in conjunction with traditional tree ring width analysis to study air pollution affects, the uptake of ozone, and changes in soil acidity over time.
