During The Orchid Show: Brazilian Modern, Plant Talk takes a look at some of the research and conservation efforts of The New York Botanical scientists whose work is focused in Brazil. This interview was conducted by Jessica Blohm, Interpretive Specialist for Public Education.
Botanical Garden scientist Dr. Wayt Thomas knows first-hand the importance of his research in Brazil. A planned highway that would have cut through the sensitive Serra Grande Forest in coastal Bahia was diverted thanks, in part, to the identification by him and his Brazilian collaborators of 458 species in an inventory of 2,500 trees—one of the highest forest diversity levels ever recorded.
“Our data about the high diversity of this forest came out while [local officials] were in the planning stage for this highway/road project. The local NGO [non-governmental organization] got our data, and they ran with it,” Wayt says.
The impressive data led officials to change the path of the road from a straight shot through the forest to a park-like road following the contours of the land and avoiding big patches of forest. In addition, a state park was created to protect that section of the forest, one of the world’s most critically endangered rain forests. Less than 5 percent of the original forests in the region remain.
“I can do my science and really have an impact on local conservation,” Wayt says.
He frequently finds species that no one has ever studied before: In Bahia, 7 percent of the tree species his team has found were unnamed. Wayt suspects that the area supports such diversity because three or four different kinds of forest intersect there. “Seeds are going to go where they want to. So you have plants that are from one forest that end up in another type of forest. The populations mix,” he says.
Wayt specializes in research of the sedge family, especially the beaked rushes, and the Tree-of-Heaven family. “In this research, I define species concepts, describe species and genera new to science, and use molecular techniques to understand the evolution of each group,” he says.
He also heads the international Organization for Flora Neotropica, which promotes the preparation of systematic monographs of plants and fungi in the American tropics.
“I have been working in this region for at least 17 years. There is no end to stuff to do here,” Wayt says.
