    International Tree Failure Database Training Session


    The International Tree Failure Database (ITFD) was developed by the US Forest Service to collect information on tree failures to aid in the prediction and prevention of future failures. The ITFD relies on contributions of tree failure data from arborists and other professionals. In order to contribute to the database, arborist must complete a training course on how to use the database. This session will provide that training and will qualify attendees to receive a password for the ITFD.
