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.

ISAO is looking for tree care companies that can donate a crew, chip trucks and chippers for a payment-in-kind TREeUnion Prep Day on Friday, 24 Sept @Kettleby Valley Camp.

We hope that our members will support this initiative to offer some much-needed tree work for this incredible kids' camp. In return, Kettleby Valley Camp is providing ISAO with a site for our in-person TREeUnion event on October 15!

The prep day will include work on medium to large trees, removal of deadwood and corrective pruning for safety. All companies will be acknowledged in an article in the Ontario Arborist with photos and logos. Lunch will be provided. Proof of WSIB and Commercial General Liability Insurance is required.

Like most companies in Ontario, Kettleby Valley Camp had to pivot in order to keep their organization running during COVID-19, which necessitated a $100K retrofit for children’s outdoor education. Some of that money was originally budgeted for planned arboriculture work that still needs to be done, some in high-risk target areas.

If your company is interested in helping out, please contact Bridget ASAP. Email [email protected]

Understanding the Social and Ecological Benefits of Urban Trees Through Tree Removal Experiments: A Call For Information

See the latest ISA Ontario Blog post by by Tenley Conway and Camilo Ordóñez — University of Toronto.

Follow the link in our bio.

By helping us identify sites for our study and share tree-related data (e.g., tree condition, tree removal schedules, etc.), you should expect to have ongoing input on our study and be the first to receive research results and implement best management practices. Besides that, you can participate in an exciting, innovative, and collaborative research project!

We believe this proposed study can increase the evidence base on the social and ecological benefits of trees, and give professionals in urban forestry the know-how for developing quantifiable standards that could be used to effectively protect urban trees.

Niagara Escarpment Commission guidance materials for review

The Niagara Escarpment is the most prominent topographical feature of Southern Ontario. The 725 kilometre long area is known for its diverse forests, cliffs, wetlands, wildlife habitat, farms, recreation areas, historic sites, towns, and picturesque landscapes. The Escarpment environment is protected by policies of the Niagara Escarpment Plan. When a proposed development has the potential to impact existing vegetation, applicants are required to submit a vegetation protection plan. To guide this process, the Niagara Escarpment Commission has developed draft technical criteria which are available for review.

The document outlines requirements for submissions and professional expertise which includes a knowledge of woody and herbaceous vegetation, growing conditions, and mitigation measures to ensure vegetation is protected and remains healthy during and after construction. As an effective tool for development review, the Niagara Escarpment Commission (NEC) has relied on vegetation protection plans for many years and guidelines have been in place since 2008.

The Niagara Escarpment Commission (NEC) invites you to provide feedback on the Draft Technical Criteria for Vegetation Protection Plans. Once approved, these materials will provide technical information to applicants and consultants preparing drawings and reports for planning and development applications within the Niagara Escarpment Plan Area.

See the NEC link in our bio »

Your feedback is valued!
Please send any comments to [email protected] or complete the online comment form.

Responses will be received until September 30, 2021.
