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

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. As a result, climbing has been proposed as a means to harvest the fruits sustainably. However, the long‐term ecological and socio‐economic impacts of climbing, rather than felling, palms remain unknown. We evaluate whether M. flexuosa populations and fruit production in managed peatland palm swamps have recovered within two rural communities in Peru where climbing to harvest palm fruits was adopted between 1999 and 2002. Since then, these communities have been supported by conservation and development projects. We conducted interviews with community members to assess perceptions of change since the introduction of climbing and carried out forest inventories to estimate changes in two socio‐economic indicators (volume of harvested M. flexuosa fruits and income) and three ecological indicators (pole stem density of M. flexuosa , seedling and sapling density, and the sex ratio of adult palms). Our results reveal that the adoption of climbing has improved the health of the forest stands and incomes in both rural communities. Recovery of M. flexuosa populations was supported by local perceptions of increases in stand productivity, improved values of most indicators within managed stands compared to reference data from unmanaged stands in the region, and continuous recovery of degraded stands over time following the adoption of climbing by both communities. Synthesis and applications . We demonstrate how long‐term conservation and development initiatives can lead to successful outcomes for rural communities and peatland ecosystems. However, urgent adoption of sustainable harvesting techniques, such as the palm climbing in our study, is needed across Amazonia to safeguard the ecological integrity of peatlands, below carbon storage, and livelihoods. This transition will require long‐term collaboration among different stakeholders, affordable management plans, and fair prices for sustainable management for peatland resources.
