As we clean up after the weekend storm, to our crews and friends: stay safe out there.

And to those assessing tree damage on your own property: hire a professional. Trees may be more damaged than we realize, electrical lines may have been contacted and hazards remain even after the storm is over. A professional has the knowledge, experience and equipment to safely assess risks.

See the link in our profile for ISA’s educational information on storm damage.

Take care out there.

Today we remember those we lost, and all those impacted by workplace tragedy.

Let’s take some time today during our tailboards to check in with each other. Be safe our there.

The ISAO Board of Directors have had to make the unfortunate and difficult decision to postpone the tREeUNION event scheduled for the 23rd of April at Kettleby Valley Camp.

Low registration numbers as well as a spike in COVID numbers have contributed to this decision. We look forward to rescheduling this event so we can finally bring our arborist community together after far too long at time apart.

We apologize for any inconvenience and look forward to seeing you soon. Please look for updates, stay safe and well.

Molly Hurford and Peter Glassford of The Consummate Athlete are hosting three sessions at ISAO's tREeUNION in-person event on Saturday, April 23.

- Nutrition + Hydration for Climbers
- Strength, Mobility + Recovery for Climbers
- and Yoga + Mindfulness

Nutrition, Strength and Mobility Considerations for Climbers

This presentation will give an overview of the ways that climbers can armor themselves against injury, increase efficiency and decrease on-the-job injuries and soreness by incorporating simple nutrition/hydration tweaks into their days and adding small amounts of strength and mobility work and/or cross-training that specifically targets muscles required to climb strong. This isn't just an area that competitive climbers need to focus on, all climbers can benefit from a focus on longevity in their career. The healthier climbers are, the longer they'll be able to continue the physical work of climbing.

Update on the Proposed Changes to the Professional Foresters Act & Regulation

See the link in our bio for more information.

Earlier this month, the ISA Ontario Chapter was notified in writing by the Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) of proposed legislative changes to the Professional Foresters Act, 2000 under the ‘Supporting People and Businesses Act, 2021’, which is currently before the legislature.

The intent of the proposed amendments is to better define the scope of practice of professional forestry and reduce overlap with other professions, like arborists.

It is with sincere thanks to the ISAO/OPFA Task Force for their efforts in reaching such a positive outcome, ISAO staff who continue to work tirelessly toward a resolution, and to all the members who reached out to their local MPPs to advocate on behalf of the arboricultural profession.
