Acorns--It's a Good Year.

Acorn production can cause crashes in animal populations that depend on acorns for food. There's good news for those little creatures that depend on acorns; 2010 is a banner year.

Acorns are cyclic; some years are a feast; some are famine, making it rough on the little creatures that depend on them.   

A flour made of acorns was once eaten by Native Americans after the tannin was leached out. Native Americans understood the acorn cycles and would plan for famine years.
