In central Panama, forest ecologist Daisy Dent oversees century-old plots at Barro Colorado Nature Monument, revealing how tropical forests naturally regenerate. These forests act as the planet's biggest terrestrial carbon sink, storing around 40% of land-based carbon. Dent's research demonstrates that natural recovery can recreate complex ecosystems in just decades, contrasting with expensive monocrop carbon-crediting schemes.
Her work shows fruit-eating animals like spider monkeys and bats plant over 70% of trees, enabling diverse forest regrowth. In contrast, homogeneous patches often result from rodent activity alone. The data provides a playbook for when to assist regeneration.
A 2024 Nature estimate found 215 million hectares worldwide—larger than Mexico—could regenerate naturally. Dent emphasizes supporting ecological interactions, from fungi aiding nutrient uptake to pollinators and seed-distributors, to grow carbon-locking forests that sustain local communities. Rather than artificial interventions, her two-decade study proves letting forests rebuild themselves is a low-cost, high-impact climate solution.
