Abstract

The preceding chapters have followed an interconnected path through the fields of green roof research to converge in this chapter on some emerging principles for the design of green roof ecosystems that extend beyond the garden aesthetic. Understanding green roof ecosystems in time and space becomes critical to good ecological design and the desire to protect and improve biodiversity in all its forms.

Scale plays a central role in ecology, providing context to understanding patterns across the space-time continuum within the local, regional, and global landscape. Review of green roof projects and research literature indicates that beyond local concern to create authentic habitat, green roof design and research has paid scarce attention to scalar relationships. As we explain in this chapter, paying attention to scale has implications for the ecological relevance of a green roof project at both socio-political and biological levels. Contextualizing how a roof will fit into time and space establishes its place on the planet and its ecological role in the landscape. Scale also plays a role in the recruitment, establishment, and regeneration of species on a roof, that in turn sets the management path towards design success and long-term survival of the roof ecosystems created.
