National Mall and Memorial ParksPermanent Lichen Biomonitoring Sites in NAMA
The A single permanent
lichen
biomonitoring site was established at Hains Point in the Potomac River.
The site was chosen to be as close as possible to the permanent IMPROVE
air quality monitoring station on the roof of the National Capital
Region Park Police Headquarters building. The IMPROVE
monitoring program was initiated in 1985 to aid in developing
Federal and State implementaton plans for the protection of visibility
in Class I National Parks and Wilderness Areas. It has been expanded
several times since. At each monitoring site, air quality data are
collected to document longterm trends and monitor improvements in air
quality. At
the Hains Point site, abundance of tree-inhabiting macrolichens
was recorded and a specimen of the
common lichen Flavoparmelia caperata was collected for elemental analysis. A link is available to
this site, where all available data can be obtained. Summary
data can also be obtained for all sites in the
NCR. NAMA map available from NPSNCR Lichens Home |
