BOREAL CLIMATIC INTERVAL

climatic period of the Holocene epoch. Radiocarbon dating indicates that the Boreal Climatic Interval began about 9,500 years ago and ended about 7,500 years ago. The Boreal followed the Pre-Boreal and preceded the Atlantic climatic intervals. Climate during the Boreal was warm and dry. In Europe the Early Boreal is characterized by forests dominated by a hazel-pine assemblage, and sea levels were regressing. In the Late Boreal a hazel-oak forest was dominant, and the seas were again transgressing the land. Climates in both phases, however, remained warm and dry.
