Have you noticed that urban/suburban landscapes seem to look similar in cities, with lawns and rows of single-family homes?  Or perhaps you've noticed how differently you manage your yard compared to your neighbors. We hypothesize these patterns are part of the American residential macrosystem, a homogenous social/ecological system distributed across diverse geographies. Across our six US study cities, plants, soils, and microclimate are more similar in residential yards than they are across the native ecosystems they replaced, driven by heterogeneous management practices that lead to a common aesthetic. I'll share how we use social and biophysical gradients to scale up.
