Monitoring Air Quality and Biodiversity
The Forest Inventory and Analysis
program seeks to assess the condition and
trend of the forests of the United States.
FIA recently assumed responsibility for all
former Forest Health Monitoring Program (FHM)
plot work on a national level.
monitoring was included in FIA in
order to address key assessment issues
impact of air pollution on forest
resources, spatial and temporal trends
and the sustainability of timber harvesting.
The Lichen Community Indicator collects data
on the epiphytic lichen community (i.e., those
species growing on trees, shrubs and standing
dead wood) on a subset of permanent forest
plots in the nationwide FIA grid. This long-
term lichen monitoring program dates back
to 1994, and is currently working in 32 states.
