DEDROCHRONOLOGY

HENRI GRISMO-MAYER HAS PUT TOGETHER ONE OF THE MOST COMPREHENSIVE BIBLIOGRAPHIES ON DENDROCHRONOLOGY AND PALEOENVIRONMENTAL DATA. THIS DATA PROVIDES A BASIS FOR FIRE PREDICTIONS AND TO DATE ARCHAEOLOGICAL SITES. DENDROCHRONOLY IS THE SCIENCE THAT USES TREE RING DATES THAT TO EXACT YEAR OF FORMATION TO ANALYZE TEMPORAL PATTERNS OF CULTURAL SITES. IT DATES SITES BASED ON TREE RINGS WHEN THE TIMBER WAS FELLED FROM PREHISTORIC SITES THAT HAVE WOOD TIMBERS OR ARTIFACTS. IN ORDER TO VIEW TREE RINGS AN INCREMENT BORER MUST BE USED. IT HAS A HOLLOW SHAFT THAT IS SCREWED INTO A TREE OR WOODEN ARTIFACT IN ORDER TO GET A CORE.

THERE IS AN INTERNATIONAL DATA BANK.. IT CONTAINS MEASUREMENTS FROM AROUND THE WORLD. YOU CAN SEARCH BY SITE NAMES, TREE SPECIES, CHRONOLOGY TYPE AND GEOGRAPHIC COORDINATES. INFORMATION IS AVAILABLE TO HELP YOU CONTRIBUTE TO YOUR TREE RING DATA SETS.

HENRI'S DATABASE PROVIDES INFORMATION REGARDING KEY TREE AND SHRUB SPECIES USED IN TREE RING RESEARCH. HIS WEBSITE IS ONE OF THE MOST USEFUL WOOD SCIENCE WEBSITES FOR EDUCATIONAL RESEARCH. IT LISTS MAJOR UNIVERSITIES THAT HAVE SET UP THEIR OWN DENDROCHRONOLOGY LABORATORIES.
TREE RING CHRONOLOGY DEPENDS UPON A SERIES OF MEASURED TREE RING PROPERTIES, SUCH AS TREE RING WIDTH, MAXIMUM DENSITY, THAT HAS BEEN CONVERTED TO DIMENSIONLESS INDICES.
