Presentation Transcript

  1. Web-based access to lichen monitoring data: The USDA Forest Service experience. L.H. Geiser, S.K. Pittam, K. Ferschweiler, J.R. Riley, A. Ingersoll, and F.J. Hanus USDA-Forest Service, Siuslaw National Forest, Corvallis, OR NW Alliance for Computational Science & Engineering (NACSE), & the Oregon Coalition of Interdisciplinary Databases, Oregon State University, Corvallis, OR

  2. 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

  3. Monitoring Area • 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.

  4. Distribution of Monitoring Sites

  5. 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.

  6. Distribution of Hypogymnia oceanica over a base map of precipitation

  7. Distribution of Lobaria oregana over a base map of annual precipitation

  8. Distribution of Lobaria oregana over a base map of average temperature during the growing season (November – May)

  9. Distribution map of Lobaria oregana over a base map of S deposition

  10. Distribution of Xanthoria polycarpa over a map indicating land ownership and topography
