CITES — the Convention on International Trade in Endangered Species — tracks the legal trade of wildlife across borders. Reading that data as a time series and a taxonomic breakdown turns a compliance record into a conservation early-warning system. Below is a worked example of how I approach that kind of analysis: a mix of trend lines, category breakdowns, and a single composite score.

The Scale of the Challenge
Reptiles, birds, and succulent plants move through North African markets in volumes that rarely make headlines. The three counters below are the kind of headline numbers a regional briefing would open with — each one counts up once it scrolls into view.

Taxonomic Patterns
Breaking seizure records down by taxonomic group is usually the first chart in any briefing — it tells you where enforcement attention is (and isn't) going. Bars animate in as you scroll to this section.

An Enforcement-Capacity Score
Composite indices compress many indicators — border staffing, lab turnaround, prosecution rates — into one number. They're blunt, but they're what gets shown to a funder or a minister. Here's what that looks like as a single gauge.
Regional Enforcement Capacity Index
A composite of reported staffing, inspection frequency, and case-resolution data across the sample. Below 50 typically signals a monitoring gap rather than low trade volume.
A seizure record tells you what was caught. It's the gap between that and the enforcement-capacity score that tells you what was missed.
What This Means for Monitoring
None of this replaces fieldwork — but it tells you where to point it. A taxon with a high seizure share and a region with a low capacity score is where the next monitoring investment should go, not necessarily where the loudest headline is.
This piece is a template for how I read trade data before I ever get in a truck — the full regional analysis, with verified figures and country-level breakdowns, is in progress.
