“Plant it and forget it for 10 years. Nothing interesting happens in young forests.”
John Parker remembers hearing that advice from a colleague who worked in tropical forests. It was the summer of 2012. Parker, a senior scientist at the Smithsonian Environmental Research Center (SERC), was on the verge of planting 20,000 tree saplings on the center’s campus. Once planted, his team would watch a new forest grow from scratch. He hoped the project would continue for at least a century.
“I was pretty worried,” Parker said. The early years were especially rough, as his lab worked to win small grants and recruit interns to help keep it going. “We didn’t forget it,” he said. “We kept the experiment running and collected data. But it was somewhat piecemeal without a big grant to hold it all together.”
Just over a decade later, the 60-acre experiment—BiodiversiTREE—is a thriving mosaic of sycamores, elms, tulip poplars and 13 other tree species. It’s attracted scientists from around the world. Some are former SERC postdocs returning with their students. Others are new collaborators.
Parker now sees the project as a model of “if you build it, they will come.” But building it was tough.
