Using the scientific study of plants to protect and preserve natural areas

The Botany Department is home to the Museum's 75,000-specimen Herbarium. The primary focus of the collection is plant occurrences in Ohio and northwestern Pennsylvania, but the Museum has specimens collected from almost every state, as well as Europe, South America, Asia and Australia.

When The Nature Conservancy founded the Ohio Natural Heritage Program in 1976 to track state occurrences of rare species, the Museum immediately began doing field inventories to contribute information for the program. Thousands of rare plant occurrences have been contributed to the program, and the Museum's contribution amounts to 10 percent of the entire rare plant database held by the State Heritage Program.

Outstanding natural areas in Ohio that have been protected in response to Museum data include:

  • Arcola Creek Marsh and Headlands Dunes State Nature Preserve in Lake County
  • Cuyahoga Wetlands and Koelliker Fen in Geauga County
  • Morgan Swamp
  • Pallister State Nature Preserve
  • McCoy State Nature Preserve
  • Grand River Terraces
  • Cathedral Woods and North Kingsville Sand Barrens in Ashtabula County
  • Singer Lake Bog in Summit County
  • Putnam Marsh on Sandusky Bay
  • The adjacent mainland section of Sheldon's Marsh State Nature Preserve in Erie County

The Museum's regional Herbarium, coupled with its strong rare plant and natural area inventory program, has produced a vital conservation data resource. Requests for that data are received by the Botany Department on a daily basis.

Undergraduate students interested in a paid summer internship in Botany are encouraged to investigate the Kirtlandia Research Internship Program.

The Herbarium is open to visitors by appointment only. Please contact Renee Boronka to arrange a visit, 216-231-4600 ext. 3505 or email
