For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.

The Biological Dynamics of Forest Fragments Project (BDFFP)—begun in 1979—has started to provide general answers to these questions. As the world's longest-running and largest study of forest fragments in the world, it has more than any other area given tropical ecologists' a sense of how forest fragments, both big and small, function. Located fifty miles (80 kilometers) north of Manaus, Brazil, the study encompasses eleven fragments, spanning from 1 hectare to 100 hectares.
"The study is very ambitious in scope, covering just about every major group of organisms. We've studied everything from trees to tamarins, and army ants to antbirds," says Dr. William F. Laurance, an ecologist at James Cook University, in a recent interview with mongabay.com. His colleague Dr. Thomas Lovejoy, biodiversity chair at the Washington DC-based Heinz Center for Science, Economics and the Environment, adds that in 32 years the research area has produced an astounding 581 publications.
