Mixed-tree forests can provide habitat in a context of industrial agriculture; pioneer native tree species are efficient in restoring healthy riparian forests and providing shelter for wildlife. Biodiversity corridors also contribute to climatic resilience as agroforestry complex systems can mitigate climate change through the sequestration of atmospheric carbon dioxide in plants and soil. Mixed plantations also improve livelihoods: it is key to understand ecosystems services and wellbeing values attributed by local communities to the reforestation of riparian areas and changes induced by the transition from monoculture plantations towards mixed-planted systems. TRAILS objective is to install oil-palm-based agroforestry systems, using selected oil palm seedlings and native forest tree species grown in locally run village nurseries. The project also aims at monitoring the dynamics of recolonization by wildlife (abundance, diversity and mobility) in areas covered with mixed-planting, riparian corridors, and oil palm plantations. The project monitors the agronomic performance of oil palms planted under agroforestry designs. TRAILS also aims at understanding key characters of climate resilience through the monitoring of bioclimatic conditions of the parcels and their ability to provide environmental services. TRAILS builds on a complementary partnership, linking academic, NGOs, private and public stakeholders, thus enabling integrated approaches arising from various science fields, from agronomy and forestry to veterinary sciences, including a detailed socioeconomic approach of changes.
