If I can explain, there are many scientific documents that speak to the width of environmental features that provide or support the function of connectivity. The old comprehensive set of policy statements before the Oak Ridges Moraine act and plan talked about the importance of hedgerows, and certainly the farming community, in terms of wildlife connections, understands the importance of those beyond soil protection.
There are widths for ecological corridors that range from 20 metres to 100 metres to 300 or 600 metres. Connectivity can be achieved. That 600 metres is based on science. There are also, depending on the context, other numbers out there.
