Long‐term interventions by conservation and development projects support successful recovery of tropical peatlands in Amazonia

People and Nature, Volume 7, Issue 4, Page 871-886, April 2025.
Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.
