We are saddened to share this 2021 International Tree Climbing Competition Update:

With the uncertainty of future shut downs, and the continuation of travel and meeting restrictions globally ISA made the decision to not hold the 2021 International Tree Climbing Competition (ITCC). The safety of our members, competitors, volunteers, and team members remain our priority.

ISA recognizes the importance of this event, and will continue to work with our volunteers, committees, and leaders to ensure we are able to host this event successfully and safely in the future. This is consistent in our decision to host the 2021 ISA International Conference virtually, and is made early in an effort to respect the time and commitment of our competitors, volunteers, and all who make this event possible.

Regional competitions may be possible as non-qualifying events; however, ISA will make determinations at a future date if those events are able to occur this year as more data becomes available. ISA appreciates your continued support during this unique time, and we look forward to hosting these events in the future.
