Biodiversity Guideline for Green Roofs

The City of Toronto has recently released its guidelines to biodiverse green roofs.  Their recent guide provides design strategies for encouraging diverse plantings.  The guide's recommendations include the following:

  • Increasing the depth of the 'growing media', the green roof version of soil),
  • creating mini- hills on green roofs to provide for a greater diversity of plants and animals
  • Providing 'perched habitats' and water features, such as bird baths, to encourage flora and fauna
  • Providing nesting opportunities
  • Designing for bees (including honey bees) and other pollinators
