In trying to describe the complex web of interrelationships between different actors, their individual values towards urban trees, and those values’ influence on city shape, I realized the potential usefulness of one my favorite tools—the concept map. This form of concept map is an application of Actor-Network Theory, which approaches landscapes of issues through analysis of the relationships between its component parts. The concept map (or Cmap) below is only one element of a larger picture, but it does a better (or at least different) job of describing the way in which different actors value urban trees.
