Still working on photos..more to come!
Over the years contributors have submitted many photos of tree failures that we have displayed at the CTFRP Annual Meetings. Lately, some have been submitted in digital format, but most are stored in boxes. The plan for the coming months is to scan and display some of the photos of the most commonly reported species (see CTFRP statistics/50 or more) illustrating typical, or sometimes unusual, failure patterns.
See below for some failure photos of less frequently reported species.
