Daniel Atha is the Conservation Program Manager at The New York Botanical Garden. He has conducted botanical field work in all 50 states of the US as well as Vietnam, Bolivia, Mexico, Belize and several states of the former Soviet Union. His work is focused on three areas: floristics—what plants grow in a particular region; taxonomy—how to tell one plant from another, what to call it and what it’s related to; and applied botany—how plants are used for food, medicine, shelter and other useful purposes.

In the area of floristics, he has published a catalog of the plants of Belize and has recently completed a botanical inventory of a nature preserve in Putnam County, New York. Recently, he has discovered two new species of knotweed for North America, one of which was found in New York City.

In taxonomy, he has published two species new to science and is currently working on a monograph of a section of the copper-leaf genus of Central America.

In applied botany, Mr. Atha has collected plant material for Merck, Pfizer, The National Cancer Institute, L’Oreal and many other organizations.

He has taught anatomy and systematic botany courses in The New York Botanical Garden’s School of Professional Horticulture and he is an associate editor of the Garden’s systematic botany journal, Brittonia.

Plant inventories are underway or completed at selected sites including Ice Pond Conservation Area, Putnam County, New York; Bog Brook Cove Preserve, Washington County, Maine; The New York Botanical Garden, Bronx County, New York; and Central Park, New York County, New York.
