Example: analyzing the effects of air pollution on tree growth by studying changes in ring widths over time.The science that uses tree rings to date earth surface processes that created, altered, or shaped the landscape.The old original roads and alleys are lined with massive large live oaks which would lead me to believe they were less than 275 years old. Better yet, if you could get two narrow samples that go across the cross-section, that would be great. When you don't have the inside of a tree, if it is rotten, you really can't produce an accurate estimate as to how old the tree is.ENTS I visited a nice large live oak on the Camp Lejun Marine base a few years ago in NC. Rings are often narrower when a tree is smaller, for geometric reasons.Definitions The Principle of Cognitive Classification The Principle of Crossdating The Prinicple of Trees as Dynamic Entities The Principle of Plurality and Parsimony The Principle of Aggregate Tree Growth The Principle of Limiting Factors The Principle of Replication across Spatiotemporal Scales The Principle of Site Selection (dendron = tree, chronos = time, logos = word = the science of): The science that uses tree rings dated to their exact year of formation to analyze temporal and spatial patterns of processes in the physical and cultural sciences.The science that uses tree rings to date when timber was felled, transported, processed, or used for construction or wooden artifacts.In addition, tree ages are derived from a variety of sources, including documented "tree-ring" count core samples, and from estimates.For these reasons, this article presents three lists of "oldest trees," each using varying criteria.
Most chronologies only go back a few centuries, but a few give longer ages than the Bible seems to allow, supposedly up to 10,000 years or so. Year-to-year variation in the width of rings records information about the growth conditions in the particular year.This is a list of the oldest known trees, as reported in reliable sources.Definitions of what constitutes an individual tree vary.The Angel Oak on John's Island, South Carolina is touted by the locals as being an estimated 1,500 years old. Certainly the estimate of 400 years for a large diameter Live Oak is not unreasonable.Ed Frank As you say, site is everything in making estimations on age by size.
