The Guidelines for Biodiverse Green Roofs, a research report led by Scott Torrance Landscape Architect Inc. and authored by Scott Torrance, Terry McGlade, Scott MacIvor and Dr. Brad Bass, are now available on the City of Toronto website. The City of Toronto Planning Department commissioned the report to support and expand on the Toronto Green Roof Construction Standard. They are meant for use by landscape architects, architects and green roof specifiers, but may also be of interest to those who wish to understand how green roofs can be designed to enhance and support biodiversity in the city.
The Guidelines for Biodiverse Green Roofs identify, describe and illustrate best practices for promoting biodiversity on green roofs in Toronto and are intended to inspire green roof creators to design for all inhabitants in the city. The guidelines provide a comprehensive list of plants suitable for green roofs that encourage biodiversity, outline recommended growing media depths and composition and provide ideas for creating habitat aimed at specific species.
