Dunham 2015 Journal article Ecological Applications Ecological Society of America http://dx.doi.org/10.1890/14-1108.1 Stream segments, aquatic organism captures, stream surveys, and road-stream crossings described by these metadata accompany a 2012 electrofishing study of the distribution and abundance of aquatic organisms (fish, lampreys, amphibians and crayfish), conducted by the U.S. Geological Survey, and the Pacific Northwest Region Aquatic and Riparian Ecosystem Monitoring Project (AREMP) of the U.S. Forest Service, in the Siuslaw National Forest in western Oregon, USA. The purpose of the study was to quantify the effectiveness of stream-road crossing restoration (culvert replacement to the stream simulation standard) in terms of numbers of fish and length of stream gained through restoration, and to quantify the continuing effects of replaced and non-replaced crossings on the probability of passage by aquatic organisms compared to stream reaches having no road crossing. The sampling design is nested in several ways; sampled stream segments (30-m electrofishing plots) were selected in a spatially balanced random sample within stream networks (contiguous spatial collections of segments within 2 km of a study culvert or road crossing). Networks themselves were randomly sampled for study from the 79 networks in the scope of inference with probability proportional to the length of stream suitable for sampling [< 25% average gradient, < 10 km2 in drainage area, and > 0.283 l.s-1 (0.01 cubic feet per second) in mean annual discharge]. The scope of inference was defined as stream within 2 km of a study crossing (303 stream-road crossings identified as potentially important to salmon and trout based on channel slope, valley bottom morphology, and stream size). At sampled segments electrofishing was used to capture aquatic organisms for identification, counting, and at a sub-sample of sites marking for capture-recapture study. Recapture passes were conducted two days after the initial electrofishing pass. The purpose of the study was to quantify the effectiveness of stream-road crossing restoration (culvert replacement to the stream simulation standard) in terms of numbers of fish and length of stream gained through restoration, and to quantify the continuing effects of replaced and non-replaced crossings on the probability of passage by aquatic organisms compared to stream reaches having no road crossing. 20120521 20120926 ground condition Complete not planned -124.4091796862 -123.26660156124 45.513739331378 43.292881853972 Location of the data collected is selected small streams (< 10 square kilometers in drainage area) of the west slope of the Oregon Coast Range within the Siuslaw National Forest, Oregon, USA.

DEM resolution in specific NetMap datasets can be determined in Arc. 20110715 Field The stream-road crossings defining the scope of inference for this study were a subset of stream-road crossings administered by U.S. Forest Service within the Siuslaw National Forest. Of these crossings, screening criteria identified stream-road crossings of importance to salmon and trout based on culvert size, outlet drop, and slope. The scope of inference (in terms of stream-road crossings) is therefore a non-random sample of crossings identified by National Forest managers. In a geographic information system we clipped a stream layer covering the extent (Netmap, accessed July 15, 2011) into 30-m, or shorter, adjacent segments. Spatial aggregations of segments were then identified as networks by clipping with 6th field hydrologic unit boundaries. Networks were then trimmed, excluding any segment greater than 2 km from a stream-road crossing in the identified scope of crossings. The Segments.txt table represents spatial data for all the segments used in the analysis of the associated journal publication. All attributes in the Segments.txt table are remotely derived (i.e. segment lengths, gradients etc. are derived in a geographic information system using the stream layer and the same 10-m digital elevation model used for its construction). Within Segments.txt, the field DEMGradient was derived by extracting elevations for each segment center and end point and then averaging across two downstream and one upstream segment (four total segments). Segments were selected for electrofishing in a spatially balanced random sample. Field personnel navigated to selected segments as well as possible using GPS receivers and landscape features. Stream wetted width and temperature data, and whether the stream was entirely dry were recorded during these stream visits (table Surveys.txt). A random sub-set of the selected segments were selected for capture-mark-recapture experiments wherein fish were marked. At capture-mark-recapture segments, block nets remained set up, and personnel returned approximately 48 hours later for a second electrofishing pass. Capture-mark-recapture segments are identified in the Surveys.txt table. Fish and lamprey captures for first and second passes, and marking information are available in the table Captures.txt. The field RankID is used to uniquely identify segments in the Surveys.txt, Captures.txt, and Segments.txt tables enabling spatial location data for captures to be linked to the point coordinates in the Segments.txt table. Point location data for segment center points are Universal Transverse-Mercator point coordinates (North American Datum 1983, zone 10).
