Tree-ring analysis or dendrochronology is both an old and a modern science. Just counting tree rings sounds simple, but in the context of forest dynamics tree age is an important and valuable parameter. The pattern of tree-ring width, wood density, element content, and other features store information on past growth conditions. Most temperate forest tree species (those growing between 25 and 65 degrees latitude), produce tree rings. Therefore, the majority of dendrochronological research occurs in these latitudes. Some species, however, are not suitable for tree-ring dating, and it is important to know and recognize which species to avoid.Wiggle dating is a method of cross dating that uses radiocarbon dating to accurately place tree rings into the holes that are found in the tree ring record. The more trees that are sampled the more accurate the radiocarbon data can be. It is just like any other experiment in the data collection stage..
