What methods are used to study urban biodiversity?

I'm designing an urban ecology study to compare green infrastructure projects. While I know common indices like Shannon's, I'm unsure how to select and integrate methods that capture not just species counts, but also ecological function and resilience in a heterogeneous, human-dominated matrix. I need a field-tested approach.

I’ve coordinated several city-wide biodiversity audits. The key is a tiered approach. Start with basic alpha diversity metrics like species richness and the Shannon index for a baseline. Then, I strongly recommend incorporating functional diversity metrics, which assess traits like diet, body size, or dispersal ability these tell you about ecosystem resilience, not just a headcount. For methodology, combine systematic transect or plot sampling in green spaces with citizen science data from platforms like iNaturalist to cover broader areas. Always geo-reference your observations to analyze patterns against urban gradients like impervious surface cover.
