The joint ISAUSDA Forest Service North American Tree Failure Database
working group met in Sacramento, California, January 28 and 29, 2003, to
finalize plans for the development of a database for recording information
on tree failures. The group was organized by John Pronos of the Forest
Service and included Larry Costello and Katherine Jones of the California
Tree Failure Reporting program; Jim Clark representing ISA; and Tom Smiley
of the Bartlett Tree Research Laboratories. From the Forest Service were
Mary Lou Fairweather, John Schwandt, Judy Adams, Joe O’Brien, Jim Worrall,
Diane Hildebrand and Bill Jones. Plans were developed to determine which
data to collect, to establish an Internet-based system of data submission,
to provide training materials, and to determine how the program should
be brought to the attention of ISA members. Initial testing of the system
should begin in August 2003, and the final system should be available August
2004. It is anticipated that data will be collected on 3,000 or more trees
per year, which will greatly expand our knowledge of the causes of tree
failures and how to predict them.
