Cost benefits of forest restoration in a tropical grazing landscape: Thiaki rainforest restoration project

•Reforestation of degraded forest lands is vital to sequester greenhouse emissions.•Carbon prices have been modeled for minimum value to incentivize reforestation.•Few studies have provided real-world costs of reforestation.•Farm-level costs and benefits are necessary to encourage farmers to uptake restoration.•Carbon prices will need to be much higher to provide positive returns.
