Chesapeake & Ohio Canal NHP

Permanent Lichen Biomonitoring Sites in CHOH

The Chesapeake and Ohio Canal National Historical Park was formed to encompass the 184.5-mile length of the Canal from Cumberland, Maryland to the mouth of Rock Creek in Georgetown. It includes natural flooplain forests from the foothills of the Appalachians to the tidewater Potomac near Washington, D.C.

Permanent lichen biomonitoring sites have been studied in the Park since the 1930's, and new sites have recently been added along the length of the Park. At each location, abundance of tree-inhabiting macrolichens was recorded and  a specimen of the common lichen Flavoparmelia caperata was collected for elemental analysis.

Links are available to each site location, where all available data can be obtained. Summary data can also be obtained for all sites in CHOH:
