Where the evidence applies
The confirmed boundary, sources and reference periods — including missing data and disclosed assumptions.
Urban Nature Audit · case studies
Better nature decisions.
Evidence you can inspect.
Compare an existing council site with three nature-based options. Understand the potential council savings, wider environmental benefits and uncertainties before deciding what to investigate next.
The first release focuses on confirmed sites in England. This is professional screening, not an ecological survey, statutory biodiversity calculation or engineering design.

A documented starting point
Three options
A consistent comparison basis
Visible limitations
What the evidence cannot tell you
No validated case-study locations have been published.
England-only appraisal scope. Generalised outline: Natural Earth. Small islands are omitted; this is not an assessment boundary or evidence of UK-wide coverage.
Real places · traceable analysis
The case-study library
In preparation
No verified geographical case studies are available yet.
We will publish a location only after its actual appraisal, evidence, calculations and report have been checked. We have not yet completed that process for the five planned examples, and we are not presenting the illustrative scenarios as real site findings.
No council commission, implemented recommendation or measured outcome is claimed.
Explore the separate synthetic illustrationWhat an appraisal should make clear
From a site question to a reviewable decision.
What changes between options
The existing site and three options, with costs, potential council savings, wider benefits and revenue kept separate.
What needs checking next
The supporting tables, uncertainty, professional limitations and further surveys or design work needed.
A decision about your site
Start with the question you need to answer.
