Most urban biodiversity plans invite participation without sharing much decision power
WHAT THE EVIDENCE SAYS
A comparative analysis examined 98 Local Biodiversity Strategies and Action Plans across 26 countries using large-language-model-assisted verbatim extraction followed by manual coding, with reported extraction accuracy of 96.4%. Seventy-one plans documented some participatory mechanism, but only 18 granted participants authority over plan content and two shared control over resources. Forty percent gave no transparency about participatory processes, and groups identified as bearing disproportionate environmental harm were often recognized without a programmatic response.
WHY IT MATTERS / OUR READ
Urban biodiversity plans are implementation systems, not just ecological inventories. Participation that collects input without changing authority can miss situated knowledge and weaken legitimacy, especially where the communities living with biodiversity loss have little control over what the plan funds or prioritizes.
CAVEATS / UNCERTAINTY
This is document analysis, not evidence that more participatory authority by itself produces better biodiversity outcomes. Plan language may not capture informal practice, the sample is not every city, and the LLM-assisted extraction—although manually coded and validated—adds a methodological dependency that should remain visible.
