Reforestation research in Latin America helps build better forests
Date:5/17/2011

A tropical forest is easy to cut down, but getting it back is another story. In a special issue of the journal Forest Ecology and Management, leading researchers at the Smithsonian in Panama and across Latin America offer new insights on reforestation based on 20 years of research.

"Twenty years ago, we had almost no information about how to build a forest," said Jefferson Hall, staff scientist at the Smithsonian and lead editor of the new special issue of Forest Ecology and Management. "People either planted one of four non-native speciesteak, pine, eucalyptus or acaciaor they used a trial-and-error process with other species that was not always successful. Now we can be smart about which trees we plant at a given site, and we understand much more about what motivates land owners and rural farmers to put this know-how to work."

Forests keep water clean, control soil erosion, store carbon, shelter animals and provide plants that offer pharmacological benefits. Forests also contribute to global-scale economic activity in the form of ecosystem services. The Agua Salud project in the Panama Canal watershed, funded by the HSBC Climate Partnership and featured in the special issue, is a 700-hectare experiment that examines the ecosystem services forests provide: water for people and the Canal, carbon storage to mitigate global warming and biodiversity protection in one of the crucial biological corridors between North and South America.

"Native tropical forests are some of the richest storehouses on earth," said Eldredge Bermingham, director of the Smithsonian Tropical Research Institute. "Now the science behind tropical forest restoration is at a level of sophistication that reforestation projects can be planned to target multiple goalsto store carbon, manage water and conserve biodiversity, buffer old-growth forests from destruction and provide a strong return on investment."
