Welcome to the International Tree Failure
Database(ITFD)
The ITFD application has an internet based form
for collecting important information about trees that have failed structurally.
Perhaps the most significant component of the ITFD is the output reports.
When the database has received a number of data entry forms for a geographic
area, reports will be generated. Over time this data will reveal the
characteristics of trees that fail and improve our ability to predict
future failures.
To access the on line ITFD form, click the ‘login’ tab
above. Existing users will enter their login name and password to begin
a new form. For new users, completion of training is strongly recommended
prior to obtaining a username and password. A list of training sessions
is provided under the ‘help’ tab.
The ITFD was designed and developed with our initial emphasis on North
America. Although it can be used for data collection and reporting
of fallen trees outside of North America, the species list and a few
other fields may require minor modification. If you are interested
in using this application outside of North America, we encourage you
to email or call for further information.
For questions, further assistance, or problems with the web site,
please email
