1 COLLABORATIVE RESEARCH IN THE PANTHER CREEK WATERSHED: WILLAMETTE RIVER BASIN, OREGON George McFadden Oregon State Office Bureau of Land Management

2 PANTHER CREEK WATERSHED Ball Bearing Mountain 2265 ft. Carlton City Reservoir 575 ft.

3 COLLABORATIVE RESEARCH PARTNERS Bureau of Land Management * Environmental Protection Agency * Natural Resource Conservation Service * Weyerhaeuser Company * U.S. Forest Service, PNW Research Station * Oregon Department of Geology and Mineral Industries * City of Carlton McMinnville Water and Light

4 COLLABORATIVE RESEARCH PARTNERS Forest Capitol Partners Oregon State University * Portland State University Seattle Biometrics * Watershed Sciences * Hampton Affiliates Yamhill Basin Council * Core Research Organizations

5 PANTHER CREEK RESEARCH OBJECTIVES Develop LiDAR stand level inventory methods Conduct a systematic soil sample Develop methods to predict distribution of soil carbon Characterize Panther Creek slope stability Characterize Panther Creek soil chemistry Assess effects of forest / land use management on carbon storage

6 PANTHER CREEK COLLABORATION TENANTS All data is part of the public record Research in landowner blind Each collaborator funds the research where they have interest Data sharing and external analysis is encouraged

12 2010 LEAF ON FLIGHT REQUIREMENTS Discrete return LiDAR at 8 pulses per square meter Hyperspectral digital imagery at up to 256 bands, probably 24 to 30 bands Wavelength return LiDAR Imagery co-registration with products from 2010 leaf on flight

13 2010 LEAF ON FLIGHT REQUIREMENTS

14 PANTHER CREEK GROUND PLOTS

15 VEGETATION SAMPLE PLOTS 42 1/5 acre circular plots Grid cells stratified into 3 by 3 block based upon tree height and canopy cover 9 plots randomly located, 1 per block 1 plot randomly located in mixed hardwood / conifer strata 3 additional plots randomly located in each “stand” where a random plot is located 2 additional plots randomly located in riparian stands

16 VEGETATION PLOT VARIABLES Species Status (live or dead) DBH Total height Height-to-live-crown Lean percent (> 10%) Dead top Location (x,y) coordinates

17 SOIL PIT PLOTS Three soil pits will be randomly selected in each of the 10 to 12 dominant kinds of soils in Panther Creek 1/5 acre plot established at each of the 36 soil pit locations selected in Panther Creek 36 total plots / Only 35 associated with soil pits as one pit location is on a skid road and was not installed but the vegetation plot was installed Measurements the same as vegetation plots

29 LANDSLIDE ANALYSIS

30 Landslide inventory mapping is greatly improved using high resolution (~8pts/m2) LiDAR data collected during leaf-on and/or leaf-off conditions In Panther Creek identified landslides went from 7 to 93 Great care is needed when using differential LiDAR DEMs to map, quantify, and interpret elevation change caused by landslides In Panther Creek 90 % of high confidence sites were active landslides but only 10 % of low confidence sites were active landslides Source:Burns, W.J., Coe, J.A., Kaya Sener, K, Ma, L., Analysis of Elevation Changes Detected from Multi-Temporal LiDAR Surveys in Forested Landslide Terrain in Western Oregon. Geological Society of America Abstracts with Programs, Vol. 41, No. 7, p. 379

31 DATA SHARING METHODOLOGY Seattle Biometrics maintains a password protected website where core researchers upload raw data sets for storage and archiving Oregon State University is developing a public website with project descriptions, sample designs, list of publications and a selected sample of raw data Bureau of Land Management will distribute the archived raw data upon request and submission of a portable hard drive for data transfer
