Collectors of the UNC Herbarium

Alan Stuart Weakley
b. 19 February 1957

The UNC Herbarium has catalogued over 250 specimens collected by Alan Weakley, and over 3,500 specimens annotated by him. As he continues to collect and to document the flora of the Southeastern United States, the UNC Herbarium will continue to be the primary repository for his specimens. He is the author of Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas (working draft of 17 January 2006).

 

Alan Stuart Weakley was born on February 19th, 1957 in Mongomery County, Maryland to William Vanner Weakley and Jean Antoinette Weakley (née Hensley). From shortly after his birth, he lived in Virginia, until attending undergraduate school at the University of North Carolina at Chapel Hill from 1974 to 1978. He received his undergraduate degree, a Bachelor of Arts, in Botany and Comparative Literature with Highest Honors, in 1978.

Following receipt of his degree, he was employed by Coastal Zone Resources, Inc. in Wilmington, North Carolina, from 1978 to 1980. Following which he attended graduate school in the Botany Department at Duke University from 1980 to 1984. In 1984 he began full time employment with the North Carolina Natural Heritage Program, a unit of the North Carolina Department of Natural Resources and Community Development, and served variously as Botanist, Ecologist, Assistant Coordinator, and acting Coordinator of the program from 1984 to 1994. In 1994, he moved to The Nature Conservancy, where he was employed as Senior Regional Ecologist, Deputy Chief Ecologist, and Chief Ecologist, from 1994 to 1999. At the beginning of 2000, The Nature Conservancy founded a new organization, NatureServe (originally called the Association for Biodiversity Information), and he transferred to that organization as Chief Ecologist, where he served until 2002.

From 2003 until the present, he is Curator of the University of North Carolina Herbarium, a department of the North Carolina Botanical Garden, itself a part of the University of North Carolina at Chapel Hill.

He is married to Allison Elizabeth Weakley (née Schwarz) and they have two children, Rhiannon Leila Fay Weakley and Vanner Waldron Weakley.
