Bees don't sign the form, but the municipal government still needs to make a decision -The rule-based conversion layer of evidence to action transforms the monitoring of municipal flower beds into auditable governance results

Urban flower beds are increasingly expected to work as climate-adaptation micro-infrastructure, not just decorative planting. Yet monitoring records still travel badly into municipal meetings, procurement documents, and public explanation. The article introduces and tests an evidence-to-action conversion layer that turns monitoring logs into auditable governance outputs through a stable BedID key, effort normalization, fixed reporting windows, KPI contracts, and versioned rule tables. Using 11 municipal flower beds in Regensburg, the study shows that, under the same reporting window and workload rules, patrol intensity can vary by up to 130-fold, which makes intuition alone a weak guide. Practitioner workshops (n = 12) further show that the workflow supports faster diagnosis, steadier prioritization under budget pressure, and clearer cross-departmental and public explanation, with high overall usability (SUS = 82.3). What this adds is a localized governance workflow that shortens the last mile between monitoring evidence and municipal action.
