Data include the number, volume, location, orientation, decay class, and pool formation roles of large wood debris pieces. River morphology is characterized by cross-section data (sampled every 100 m) and in sketch map in the Nakamura and Swanson (1994) publication. This was a one-time sample in 1991 employing simple tape and compass field techniques (Nakamura and Swanson 1994). Data tables cover 1. wood piece measurements (diameter, length, location, decay class) and 2. channel geometry measurements. geomorphology disturbance woody debris coarse woody debris organic matter aquatic ecosystems streams LTER controlled vocabulary disturbance organic matter LTER core research areas Related PublicationsNakamura, Futoshi; Swanson, Frederick J. 1994.

(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - GS016 From July to Sept of 1991, mapping was carried out by using the valley floor map created in a GIS. Other characteristics of the woody debris were measured in the field by tape and observation, except orientation which was indirectly measured based on the GIS map. Average channel width and sinuousity were calculated from the GIS map as well. The study area is the valley floor of a mountain watershed. Gradient is steep (ca. 0.02), substrate is large boulders, large wood (pieces of old-growth trees with diameters up to nearly 2 m) is abundant, and channel reaches vary from wide and braided to highly constrained by bedrock, alluvial fans from tributaries and also large landslide deposits from adjacent hillslopes. Sampling frequency: once Field mapping of coarse woody degris with measurements of length, diameter, decay class, location, orientation, and pool formation. Calculation of channel width and sinuousity from GIS map. Sherri L. Johnson

Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics. Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition. The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms. 1 GS01601 Woody debris data: GS01601.csv 109305 d109e922b29a2eaaa1288b8399d23fe5 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=GS01601_v1.csv STCODE Study code char(5) Study code FORMAT Format numeric(1,0) number 1 natural 1.0000 1.0000 LOGNUM Log number numeric(4,0) number 1 natural 1.0000 1692.0000 SITENUM Site number numeric(4,0) number 1 natural 1.0000 1107.0000 ANGLE Angle of log to channel (acute angle) char(1) 1 0 - 45 degrees 0 No angle measurement taken 4 135 - 180 degrees 2 45 - 90 degrees 3 90 - 135 degrees SECTNUM Number of 50 meter channel section numeric(2,0) number 1 natural 1.0000 85.0000 SUSPEND Is log totally suspended char(1) 1 Yes 0 No MAINSTRM Is log in main channel char(1) 1 Yes 0 No SIDESTRM Is log in side channel char(1) 1 Yes 0 No ABNDSTRM Is log in abandoned channel char(1) 1 Yes 0 No SANDBAR Is log in a sandbar or floodplain char(1) 1 Yes 0 No SIDESLOP Is log on side slope char(1) 1 Yes 0 No TERRACE Is log on terrace char(1) 1 Yes 0 No BOULDER Is log touching a boulder > 1 meter in diameter char(1) 1 Yes 0 No LOG Is log touching another log char(1) 1 Yes 0 No POOL Did log contribute to pool formation (see nakamura paper for criteria) char(1) 1 Yes 0 No DIAM1 Diameter of log at one end numeric(3,0) centimeters 1.000000 integer 2.0000 175.0000 DIAM2 Diameter of log at other end (if diam1 = diam2, log was measured in the midd le only) numeric(3,0) centimeters 1.000000 integer 3.0000 170.0000 LENGTH Length of log numeric(4,1) meters 0.100000 real 0.8000 50.0000 TOTLOGVOL Volume of log computed as (pi * (diam1+diam2)*length/8) * multfctr numeric(5,2) cubic meters 0.010000 real 0.0100 56.5700 DECOMP Decomposition code char(1) 2 Bark partially attatched, log hard 5 Extremely decayed log 1 Bark tight, log hard 3 No bark, log hard 4 No bark, log soft MULTFCTR Multiplication factor to correct volume measurement to reflect the true volu me of the log in the channel area numeric(4,2) number 0.010000 real 0.1000 1.0000 NOTNULL GS01601.ABNDSTRM GS01601.ANGLE GS01601.BOULDER GS01601.DECOMP GS01601.LOG GS01601.MAINSTRM GS01601.POOL GS01601.SANDBAR GS01601.SIDESLOP GS01601.SIDESTRM GS01601.SUSPEND GS01601.TERRACE GS01601.STCODE GS01601.DIAM1 GS01601.DIAM2 GS01601.FORMAT GS01601.LENGTH GS01601.LOGNUM GS01601.MULTFCTR GS01601.SECTNUM GS01601.SITENUM GS01601.TOTLOGVOL 2 GS01602 Channel section geomorphological data: GS01602.csv 5087 a2c0717ed25123ad5b17d8362a2b6fab 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=GS01602_v1.csv STCODE Study code char(5) Study code FORMAT Format numeric(1,0) number 1 natural 2.0000 2.0000 SECTNUM Number of 50 meter channel section numeric(2,0) number 1 natural 1.0000 85.0000 NUMLOGS Number of logs in the section numeric(3,0) number 1.000000 integer 0.0000 126.0000 VOLUME Volume of all logs in the section numeric(6,2) cubic meters 0.010000 real 0.0000 249.4100 AREA1 Map area of the section (including channels, floodplains, and bars) numeric(5,2) square centimeters 0.010000 real 4.6700 35.4500 WIDTH Average section width numeric(5,2) meters 0.010000 real 9.3400 70.9000 THWGLEN Map length of thalweg numeric(4,2) centimeters 0.010000 real 4.8300 7.5300 SUMTHWG Sum of map length of thalweg in the preceding, current, and following sections. numeric(5,2) centimeters 0.010000 real 10.1200 19.3300 DIRTHWG Direct map length from upstream end of preceding section thalweg to downstream end of following section thalweg. numeric(5,2) centimeters 0.010000 real 8.9900 17.3600 LSINUOUS Sinuousity - sumthwg / dirthwg numeric(5,2) number 0.010000 real 0.9900 1.7100 GEOMTYPE Geomorphic type code char(1) 4 Ave section width < 19.0 meters, sinuousity < 1.09 (type nst in paper) 2 Section width > 19.0 meters, sinuousity < 19.0 meters (type wst in paper) 3 Ave section width < 19.0 meters, sinuousity > 1.09 (type nsi in paper) 1 Section width > 19.0 meters, sinuousity > 1.09 (type wsi in paper) NUMCHANS Number of channels code char(1) S Single channel in section M Multiple channels in section BOULDERS Presence of boulders >= 1 meter in diameter char(1) B Boulders >= 1 meter in diam exist in the section PRIMARY GS01602.SECTNUM NOTNULL GS01602.GEOMTYPE GS01602.NUMCHANS GS01602.STCODE GS01602.AREA1 GS01602.DIRTHWG GS01602.FORMAT GS01602.LSINUOUS GS01602.NUMLOGS GS01602.SECTNUM GS01602.SUMTHWG GS01602.THWGLEN GS01602.VOLUME GS01602.WIDTH square centimeters dimensionless number, i.e., ratio, count centimeters; .01 meters cubic meters meter; SI unit of length
