Coweeta Synoptic Data from 49 sampling sites in the Upper Little Tennessee River Basin from 2009 to 2010 (drainage area, slope, particle size data)
This data was generated as part of synoptic sampling conducted at the Coweeta LTER between June 2009 and May 2010. 49 wadeable streams with low levels of development were sampled throughout the Upper Little Tennessee River Basin in the Southern Appalachians. This dataset contains the location code (visually categorized basin landcover), drainage area, slope, riparian code (visually categorized riparian conditions), percent fines (<2mm), and median particle size (D50) calculated from a Wolman pebble count. The purpose of this study was to investigate the effects of riparian vegetative conditions on a suite of channel morphological variables. At each site, a uniform 150 meter section of stream was surveyed. Within each reach, the active and bankfull channel widths were measured every 5 meters, where active channel width was defined as the vegetationless channel bed from left vegetation break to right vegetation break. All wood exceeding 10 cm diameter and 1.0 m length were tallied. A Wolman pebble count (N = 100) was conducted on the coarsest riffle in each stream reach. Slopes were measured from the upstream end of riffles over three riffle-to-riffle sequences with a level rod and tape. Riparian conditions at each reach were visually categorized. Drainage area was determined from 2006 Landsat imagery.

Coweeta Synoptic Data from 49 sampling sites in the Upper Little Tennessee River Basin from 2009 to 2010 (active channel width, bankfull width, and channel depth data)
This data was generated as part of synoptic sampling conducted at the Coweeta LTER between June 2009 and May 2010. 49 wadeable streams with low levels of development were sampled throughout the Upper Little Tennessee River Basin in the Southern Appalachians. Active channel width, bankfull width, and channel depth were measured every 5 meters for 150 meters at synoptic stream sites. Effects of riparian vegetative conditions on a suite of channel morphological variables were investigated: active channel width, variability of width within a reach, large wood frequency, mesoscale habitat distributions, median particle size, and percent fines. At each site, a uniform 150 meter section of stream was surveyed. Within each reach active channel width, bankfull channel width, and channel depth were measured every 5 meters. Active channel width was defined as the vegetationless channel bed from left vegetation break to right vegetation break.

Coweeta Synoptic Data from 49 sampling sites in the Upper Little Tennessee River Basin from 2009 to 2010 (diameter of LWD data)
This data was generated as part of synoptic sampling conducted at the Coweeta LTER between June 2009 and May 2010. 49 wadeable streams with low levels of development were sampled throughout the Upper Little Tennessee River Basin in the Southern Appalachians. Effects of riparian vegetative conditions on a suite of channel morphological variables were investigated: active channel width, variability of width within a reach, large wood frequency, mesoscale habitat distributions, median particle size, and percent fines. Diameter of large woody debris (LWD) in each stream reach were tallied in this specific dataset. At each site, a uniform 150 meter section of stream was surveyed. All wood in a reach exceeding 10cm diameter and 1.0m length were tallied. Observers kept a tally of the function, if any, of the large woody debris within the channel (e.g. pool formation, jam formation, bank protection, etc.).

Patch occupancy sampling of invertebrates and salamanders from Coweeta Synoptic sampling sites located in the Upper Little Tennessee River Basin, 2009 to 2012.
This research was conducted in Macon County, North Carolina, as part of the Coweeta LTER synoptic sampling program. In the summers of 2009-2012 we sampled and counted Tallaperla species, Elimia species, fish, and salamanders found in a 150meter stretch at the synoptic sites, a total of 44 sites. The 150meter stretch was divided into thirty 5meter plots that were sampled on three occasions each year of sampling; in 2009 all 44 sites were sample, in 2010 a subset of 8 sites were sampled, in 2011 a subset of 9 sites were sampled, and in 2012 a subset of 8 sites were sampled.
Synoptic Sampling Program GIS data.
Coweeta LTER researchers sampled fifty-eight stream sites in the Upper Little Tennessee River Basin in February and June of 2009. Sites were selected to represent the range of land cover and land use within the basin. Samples were taken over three days of stable weather and discharge during periods of baseflow. They were used to characterize conditions across the basin during the growing and the non-growing seasons without the influence of elevated discharge. The GIS data presented was used to both help in selecting the 58 sites. The GIS files are split between raster and vector files. The files are in .zip archives. There are text files with information about each GIS in the .zip files.
