2. Data Questions What data needed to characterize CLs across broad landscapes (extensive) What data are needed to establish cause/effect relationships (intensive) How can we leverage existing data –What addtl data are needed –How to fill gaps

3. I G. S. P. S. Extensive Intensive Sites Gradient Survey Probability Survey Extensive Sites Modeling* Four levels of data collection & analyses * Allows for the identification of prioritized parameters

4. Extensive Sites NADP/NTN IMPROVE ECOMAP MDN Natl wetland inventory NHD TEUI Human pop density maps NEI AIRS

5. Extensive Sites – cont’d Remote Sensing –Hyperspectral imagry –Tree health – insect/disease –MODUS (AQUA & TERRA) –Airborne lidar – canopy structure –Soil depth to bedrock? –Soil mosture

6. Probability Surveys EMAP and FS Sfc water surveys FIA/FHM CWA 305B, 303D – STORET Terrestrial survey (R3)

7. Gradient Surveys Allows scaling from intensive to extensive –Linking can b e done via R. S. –Needs linking to maps (e.g., weathering) –Sources are from projects Examples –NAWQA Synoptics –CA Bay Delta Study –PACFISH

8. Intensive Sites Look at 7 remaining candidate FS sites identified from 2004 CENR intensive sites LTER Experimental Forests (FS) NPS 3 intensive sites –RMNP (Loch Vale), GSMNP, SNP LTBMU WACAP – NPS toxics NPS Vital signs program W. Adirondacks/Poconos, Catskills

9. Data Needs Natl forest soils inventory Regional maps of weathering Disturbance maps –Fire –Harvesting –Drought –Extreme events Additional intensive sites

10. Key Points Western intensive sites/data are less certain in the west due to diversity, elevation differences, site sparseness Data need to be collected simultaneously for both aquatic and terrestrial Not just class I areas Initial focus is on forests (prototype sites) but soon find alpine and range sites
