Title: The Decline of Orchid Populations in the Catoctin Mountains
Speaker: Wes Knapp, Eastern Regional Ecologist, MD DNR
A forty year study (1968 to 2008) of the orchid populations of the Catoctin Mountains, Frederick County, Maryland reveals that 19 of 21 species of orchids have experienced a precipitous decline. Four of these species are currently considered Threatened or Endangered by the State of Maryland and another two are considered Rare. Proper management is critical for the continuation of the orchid species in this study, be it control of the white-tailed deer herd or combating woody plant succession.
