The Canopy Global 1000 ranks the world’s land protected areas by conservation value: how irreplaceable the species they hold are, how connected they are to other protected land, and how intact they are, weighted by size. Plant data is being added to the ranking, so both versions are shown side by side. Neither is the final word.
Without plants, Tropical Rainforest Heritage of Sumatra ranks 6 of 1,000. With plants it ranks 42. It stays in the top 300 either way, which is why it is here.
Management-effectiveness ratings published outside Canopy, each on its publisher’s own scale. They are not PACE scores, some are self-assessments, and different methods and years are never converted into one another or ranked together.
IUCN World Heritage Outlook: overall protection and management, 2025: Some Concern. The scale’s categories, in the publisher’s order: Highly Effective, Mostly Effective, Some Concern, Serious Concern.
Assessor: IUCN expert assessment and review process; individual assessor not named on retrieved page. Published overall protection-and-management category, not the conservation-outlook category.
Scale: Protection and management categories. Not the conservation outlook, threat or values scale.

116.0 million tonnes of carbon inside the boundary is irrecoverable: if it were lost, it could not be recovered by 2050.
25,625 km² of the area was forest in 2000, 100% of it. 1,437.1 km² of that forest was lost between 2001 and 2024, 5.6% of the 2000 cover.
Forest means at least 30% tree canopy in 2000. Loss counts any clearing, including fire and natural disturbance, not only deforestation.
Canopy’s PACE management score, its country readiness score (C-RISK) and its weekly satellite feeds cover African protected areas today. They have not been published for this area.
