A tree ring sequence is only useful in the region in which it was developed because
 
  a. trees respond to climate and climate is regionally variable.
  b. researchers tend not to share their data with one another, and thus each area needs its own specialist.
  c. tree rings are partially conditioned by soil chemistry which can be highly variable over small distances.
  d. in order to be useful, tree rings must be calibrated using radiocarbon dating, and calibration curves are regionally specific.
  e. the analysis is difficult and time consuming, hence several localized laboratories are necessary to process the quantity of samples.
