Web-based access to lichen monitoring data: The USDA Forest

Service experience.

The USFS lichens and air quality database is now "on-line".

Query:• 1650 sites and 41,262 lichen records

from Oregon, Washington and southeastern Alaska

Obtain: • species lists/distribution maps• habitat and location data• tissue concentrations of 27 elements

from 12 lichen and 2 moss species• deposition estimates for sulfur and

nitrogen• air pollution scores from lichen

community data

• National Forests of western Washington and Oregon, including the Columbia River Gorge National Scenic Area.

Sampling Intensity• Lichen data collected from the permanently marked,

3.4 mile USFS regional Current Vegetation Survey grid.

• 1/4 of the grid points are monitored each year for 4 years. Repeat every 10 years.

Monitoring Area

Distribution of Monitoring Sites

At each Monitoring Site:• A 2 hour survey is made of epiphytic macrolichens,

following FHM methods.• 2 lichen and/or moss species are collected for

tissue analysis of S,N, and 15-25 other elements.
