CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Strong floristic distinctiveness across Neotropical successional forests

Exporter la citation

Forests that naturally regenerate on abandoned fields play a crucial role in restoring biodiversity and ecosystem services, but their ability to preserve distinct regional tree floras remains a key question. A study analyzing the floristic composition of 1,215 early successional forests (≤20 years old) across 75 human-modified landscapes in the Neotropic realm identified 14 distinct floristic groups, with a high between-group dissimilarity of 0.97. These groups were strongly influenced by location, bioregions, soil pH, temperature seasonality, and water availability, highlighting the large-scale continental variation in species composition. Interestingly, human disturbance indicators did not significantly shape these floristic patterns, suggesting that biogeographic and environmental factors are the primary drivers of species distribution in early secondary forests. The distinctiveness of these forests is partly maintained by regionally restricted species within widespread genera, reinforcing their ecological importance. Given their role in conserving bioregional uniqueness, forest restoration efforts should prioritize the use of local species to ensure the preservation of these distinct floras.
