Each country's status is an aggregation of its Ramsar wetlands' condition trends — the share of sites whose satellite-derived indicators are significantly improving versus declining over recent decades. Explore the map or the table; select a country to see its sites.
| Country | Sites | Improving | Declining | Stable | Net trend |

For every Ramsar site, each satellite indicator with at least 6 years of data is tested for a monotonic trend using the non-parametric Mann-Kendall test (Kendall's τ). Trends are direction-adjusted so an increase counts as improvement only where it is ecologically favourable (fire and bare-soil are inverted). A site is classed improving or declining by the sign of the mean of its statistically significant (p < 0.05) adjusted trends, otherwise stable. A country's net trend = (improving − declining) ÷ sites with sufficient data. National status is an aggregation of site-level assessments, consistent with the project's reporting framework. Indicators and per-site data come from the Assessment Tool dataset; recently-listed sites without geolocation are omitted from the map.
