SUB-BOREAL CLIMATIC INTERVAL

division of Holocene chronology (the Holocene Epoch began about 10,000 years ago and continues to the present). The Sub-Boreal Climatic Interval followed the Atlantic and preceded the Sub-Atlantic Climatic Interval. The Sub-Boreal, dated by radiocarbon methods, began about 5,100 years ago and ended about 2,200 years ago. It is correlated with pollen zone VIII, and the climate was warm and dry. The Sub-Boreal forests were dominated by oak and ash and show the first evidence of extensive burning and clearance by humans. Domesticated animals were abundant, as well as natural fauna.
