Was this land forest, and when did it lose tree cover? For an afforestation, reforestation and revegetation (ARR) carbon project, that history is one of the first eligibility questions. The analysis reports tree cover in 2000 and the loss since, in hectares and on the map, plus the hectares gained from 2000 to 2012.
Screen candidate land for ARR before you commit to it. Land that lost tree cover recently needs a closer look, and the loss years show when.
Compare candidate properties on the same measure before deciding which ones to visit.
Show a site’s recent tree cover history beside the planting records, from a dataset reviewers already know.
A property boundary as a polygon, and these settings, which you can change before each run.
| Setting | Default | Range |
|---|---|---|
| Minimum tree cover percentage to be considered forest (0-100) | 30 | 0–100 |
Run it first, at pre-feasibility, on every candidate property. Land with recent loss gets a closer look; land that has been open for a long time moves on to the land structure and canopy height checks, a field visit and, later, the documents you prepare for a standard such as Verra.
No single dataset can. Verra’s rules look at the 10 years before the start date: VM0047 excludes land that was managed forest in that period, and the VCS Standard asks for evidence that any ecosystem degradation in those years was not caused by the project. This analysis shows where a global dataset detected tree cover loss and in which years, so you know which land needs dated imagery, records or field checks before you commit.
The default is 30%. Use the crown cover threshold in the forest definition your country reports under the UN climate rules; those thresholds sit between 10% and 30%. You can change it before each run.
The analysis uses version 1.12, where loss runs to the end of 2024. Gain only covers 2000 to 2012. For the land today, use recent imagery, degraded land mapping or a field visit.
A property boundary as a polygon, drawn on the map or imported from a KML, shapefile or GeoJSON file. The result is saved on the property, beside its other records and maps.
