Extinction debts incurred due to human actions have shorter timescales. Local extinction of birds from rainforest fragmentation occurs over years or decades, [13] while plants in fragmented grasslands show debts lasting 50–100 years. [14] Tree species in fragmented temperate forests have debts lasting 200 years or more. [15]
