The ecologist revealing the invisible networks that revive rainforests
In a research station in central Panama, you can walk through a century of forest time, watching scrubby plots of adolescent trees give way to cathedral-like canopies of mature growth. Forest ecologist Daisy Dent, a senior scientist at ETH Zurich, oversees this sequence of plots across the Barro Colorado Nature Monument, some of which date…
In a research station in central Panama, forest ecologist Daisy Dent oversees a century-long sequence of forest plots at the Barro Colorado Nature Monument. Her work reveals how tropical forests, which store around 40% of land-based carbon, can regenerate naturally after destruction. Dent's research in Panama, a product of Prorena, a joint Smithsonian-Yale initiative, challenges the notion that large monocrop plantations are the most effective approach.
Instead, her data shows that animal dispersers, particularly fruit-eating species like spider monkeys, bats, and parrots, play a crucial role in reforestation. By analyzing which animal communities built each patch, she found that a diverse 70-year-old patch had a more robust canopy than a patch dominated by a single species of tree.
The key to successful reforestation lies in supporting the complex interactions between species, from fungi that help trees absorb nutrients to pollinators and seed distributors. While some startups propose technological solutions like seed-spraying drones, Dent's decade-long research in Panama demonstrates that nature itself can be a powerful ally in recovering forests.
