Evidence

Peer-reviewed

Geography

Modified peat-swamp forest and Acacia plantations, Sumatra, Indonesia

System

Tropical peat forest / working landscape

## WHAT THE EVIDENCE SAYS

Across 17,132 camera-trap days in a proposed nature-based-solutions landscape, researchers recorded 23 medium-to-large mammal species. They detected six species in young Acacia plantations, 11 in mature plantations, and 19 each in linear forest remnants and core forest. The team modeled habitat priorities for eight threatened or conservation-concern species and explored alternative landscape configurations under explicit scenario assumptions.

## WHY IT MATTERS / OUR READ

Peatland management is not simply a choice between intact reserves and production plantations. Narrow remnants may carry disproportionate conservation value and provide a practical starting point for protecting habitat structure, while the modeled scenarios help frame decisions about corridors and land cover rather than proving future outcomes.

## CAVEATS / UNCERTAINTY

Camera detection and modeled habitat suitability are not direct measures of abundance, population trends or realized restoration gains. The scenarios hold peat depth, roads and water features static; they are planning hypotheses in one Sumatran landscape, not field-tested forecasts of species recovery.
