Data were collected on stream habitat, benthic algal, biota (fish, salamanders and macroinvertebrates), and riparian forest cover across a total of 9 streams: 7 streams in the HJ Andrews basin/Lookout Creek stream network; one stream in the westward adjacent Blue River basin, and one stream in the eastward adjacent Deer Creek river basin. In each stream there were 2 study reaches – one bordered by old-growth riparian forest and the other bordered by regenerated second-growth riparian forest on at least one bank (with a stand ages that generally ranged between 30 and 60 years). In each study reach (80 – 150 m), we collected the following data: pool habitat, wetted and bankfull widths, large wood abundance and volume, riparian forest canopy cover, benthic algae accrual on tiles, stream macroinvertebrate abundances (from 6 replicate surber samplers, which were pooled and then sub-sampled, identified and measured), age 1+ cutthroat trout (Oncorhynchus clarkii clarkii) abundance and biomass, age 0+ (young-of-year) trout abundance and biomass, coastal giant salamander (Dicamptodon tenebrosus) abundance and biomass. Fish and salamander abundances were calculated by either mark-recapture or multiple pass depletion methods. land use history stream ecology trophic dynamics light streams algae aquatic invertebrates salamanders trout LTER controlled vocabulary riparian ecosystems Andrews Experimental Forest site thesaurus As part of this research effort, we revisited sites that were initially sampled by Murphy and Hall (1981), which are also included in the thesis of Michael Murphy (1979).

(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - AS010 Field Sampling-Abiotic Variables: All data were collected in the summer of 2014 during low-flow conditions. Across all nine pairs of sites, we collected a suite of physical habitat variables in each reach including: canopy cover, bankfull width, wetted width, pool area, large wood abundance and volume, temperature, nutrient concentration, and stream gradient. Canopy cover was quantified using a convex spherical densiometer (Forestry Suppliers Model A). Measurements were taken in each cardinal direction at 11 regularly spaced locations in each reach. All densiometer measurements were taken by the same individual to avoid user bias. Bankfull width and wetted width were measured at transects across the same 11 reach locations. The mean wetted width for each reach was multiplied by reach length to obtain total reach wetted area, which was used to standardize fish, salamander, and invertebrate abundance and biomass estimates per square meter of stream. Pools were identified during summer-low flow conditions as slow velocity habitats connected to the main-channel. Pool area was calculated using the length and width of each pool, and percent pool area was calculated as the total pool area divided by total wetted reach area. We quantified all large wood pieces greater than 1 m in length and 10 cm in diameter (Richmond and Fausch 1995, Young et al. 2006, Warren et al. 2009) We only measured the portion of wood pieces located within the bankfull channel for wood volume estimates. Total channel area (mean bankfull width multiplied by reach length) was used to standardize large wood volume among reaches. Temperature loggers (HOBO Pro v2) were deployed for two weeks during mid-summer to evaluate relative temperature among streams and differences between paired reaches. Due to a limited number of sensors, not all sensors were deployed for the same time interval. Sensors were deployed from 7/20/14-8/3/14 in Cook Creek and Fritz Creek and from 8/4/14- 8/24/14 in all other streams. Water samples were collected in September 2014 at all reaches during a two-day period prior to the onset of autumn rain events in this region. Water samples were filtered (25 mm Whatman GF/F filters), frozen, and analyzed for nitrate-N (NO3-N) and phosphate-P (PO4-P) using a Dionex 1500 Ion Chromatograph. Nitrogen is the limiting nutrient for stream autotrophy in the streams evaluated in this study (Gregory 1980, Warren et al. 2017). Field Sampling-Biotic Variables: Periphyton chlorophyll a (hereafter chl a) accrual was quantified on 10 ceramic tiles (15 x 15 cm) per reach. Tiles were placed in the stream in mid-July and were retrieved after six weeks. Tiles were spaced at regular intervals and positioned within riffle sections of the stream at a depth of 10-25 cm. After six weeks, tiles were scraped using a wire brush and the slurry was filtered through 47 mm glass fiber filters (Whatman GF/F). Filters were placed in 20 ml glass vials and frozen for 24-48 hours. Benthic invertebrates were sampled in late July (7/15/14-7/29/14). Both reaches within a reach pair were always sampled on the same day. In each reach, six surber samples (363 µm, 0.0625 m2) were collected from riffle habitats at regular intervals. Substrate within the surber sample quadrate was disturbed to a depth of 10 cm for approximately 30 seconds. Samples were stored in 90% alcohol until laboratory processing. Fish and salamanders were collected using a backpack electroshocker (Smith-Root model LR-20B). Block nets were set at the upper and lower ends of each reach to prevent movement and close the system for the duration of the surveys. Population estimates were conducted using single-pass mark-recapture methods for all reach pairs except Mack Creek. For mark-recapture surveys, fish and salamanders were anesthetized using AQUI-S 20E (AQUI-S, Lower Hutt, New Zealand), weighed (nearest 0.01 g), measured (total length for fish, and snout-vent length for salamanders), and marked. Fish were marked with a small caudal clip and salamanders were marked with a visual elastomer tag (Northwest Marine Technology, Shaw Island, Washington). Fish and salamanders were released and the reach was resurveyed after approximately 24 hours. The number of marked and unmarked individuals was recorded for each species. Abundance was estimated using the Lincoln-Peterson mark-recapture model, modified by Chapman (1951), and biomass was estimated by multiplying abundance estimates by mean weight. Juvenile (0+) and adult (1+) trout were analyzed separately. Trout were distinguished as juvenile or adult based on length frequency histograms and, in general, trout less than 65 mm were classified as juveniles. Multiple pass depletion methods were used to survey fish and salamanders at Mack Creek. Mack Creek is a long-term ecological research (LTER) site where fish and salamanders are sampled annually using depletion estimates. The long-term research project provided the 2014 fish and salamander data used in this study (S.V. Gregory). Multiple pass depletion and mark-recapture methods can produce significantly different population estimates (Rosenberger and Dunham 2005). To standardize population estimates across all reaches, we applied a correction factor that was obtained from simultaneous mark-recapture and depletion estimates conducted in Mack Creek in 2015 (S.V. Gregory) per Thompson and Seber (1994). In addition to the primary fish and salamander surveys conducted in mid-summer, a second single-pass survey was conducted in late September 2014 to capture juvenile (age 0+) cutthroat trout and assess summertime relative growth rates for this age class. We did not sample Mack Creek in the second juvenile assessment as we did not want to interfere with long-term research efforts occurring annually at this site. In LO701, MCTE, and Fritz Creek, juvenile trout were surveyed on two sampling dates but there were few surveyed fish in at least one of these surveys (n less than 5). Therefore, we were only able to evaluate juvenile relative growth rates in 5 of the 9 sites. Relative growth rates were determined by subtracting the mean weight at survey date 1 from the mean weight of survey date 2 and then dividing this number by the number of days between sampling events. Laboratory Methods - AS010 Chlorophyll a; We extracted Chl a from filters with 15 mL of 95% acetone for 2 to 4 h and estimated Chl a based on fluorometric methods with phaeophytin corrections as outlined in US Environmental Protection Agency (EPA) method 445.0 (Arar and Collins 1997). Fluorescence of a subsample of the extraction solution was measured before and after the addition of 0.1 N HCL (0.15ml/5ml solution). Invertebrates: In the laboratory, the contents of each of the six surber samples from each reach were combined into a single pooled sample. This pooled sample was then subsampled using a plankton splitter until a minimum of 500 individuals were picked from the subsample. We conducted a 60 second visual search of the remaining sample (less the subsample) to collect large bodied predators to more effectively quantify invertebrate predator biomass. Invertebrates were identified to Family or Genus (Merritt et al. 2008) and individually measured using an ocular micrometer mounted on the dissecting microscope. Invertebrate lengths were converted to biomass using established length- weight relationships (Sample et al. 1993, Sabo et al. 2002, Mark Wipfli; unpublished data). We summed the biomass of individuals within a subsample and divided this summed value by the proportion of the total sample that was subsampled. The addition of this value and the biomass of the 60-second sample to identify large bodied individuals (which was not subsampled) was then divided by the total area sampled (0.375 m2) to obtain biomass estimates per square meter (g/m2). The previously harvested cutblocks were cleared 40-60 years prior to this study. In all cases, timber was removed down to the stream bank with no riparian buffer. Trees were replanted within 5 years post-harvest in seven of the nine cuts in accordance with forest management practices at the time. Stands in MCTW and Mack Creek were regenerated without any post-harvest planting. In 2014, the second growth riparian forests were predominantly Douglas fir (Pseudotsuga menziesii) but red alder (Alnus rubra) was also a common canopy species in areas directly adjacent to streams and provided substantial stream shading. Old-growth forests were comprised of Douglas fir, western hemlock (Tsuga heterophylla) and western red cedar (Thuja plicata). Red alder was present adjacent to streams within old-growth forests as well, but it was not as common as in second growth sections. Coastal cutthroat trout and coastal giant salamanders (Dicamptodon tenebrosus) were present in all 18 stream reaches and were the dominant vertebrates. Sculpin (Cottus spp.) were present in both reaches of MR404, but were not found in any other reaches. Tailed frogs (Ascaphis truei) were found in low abundance in some of the streams, but were not evaluated in this study. Description of distinction between old-growth and second growth study reaches: COOK - Cook Creek, a tributary of Blue River upstream of Blue River reservoir and north of the HJ Andrews FRITZ - Fritz Creek, a tributary of Deer Creek, which flows directly into the McKenzie River, NE of the HJ Andrews LO701 - Harvest block LO701 on Lookout Creek. Second growth section was in cutblock of LO701. The downstream end of this reach was 180 m upstream of the cutbreak. The old-growth section was downstream of cut LO701. The upstream end was 75 m downstream from the cutbreak. LO703 - Harvest block LO703 on Lookout Creek. Second growth section was in cutblock of LO703. The downstream end of this reach was 85 m upstream of the western edge of cutbreak LO703. The old-growth section was upstream of cut LO703. The downstream end of the reach was 50 m upstream from the eastern edge of cutbreak LO703. MACK - Mack Creek. This site is part of an LTER fish study. MCT_E - McRae Creek east tributary . Second growth section was in cutblock of L504. The old-growth reach was upstream of the second growth reach here. The upstream end of the second growth reach was 200 m downstream of the cutbreak. The downstream end of the old-growth section was 35 m upstream of the cutbreak. MCT_W - McRae Creek west tributary. Second growth section was in cutblock of L503. The downstream end of the second growth reach was 90 m upstream of the cutbreak. The upstream end of the old-growth section was 50 m downstream of the cutbreak. MR404 - Harvest block L404 on McRae Creek. Second growth section was in cutblock of L404. The downstream end of the second growth reach was 110 m upstream of the cutbreak. The upstream end of the old-growth section was 80 m downstream of the cutbreak. STR - Harvest block L504 on McRae Creek. Second growth section was in cutblock of L504. The old-growth reach was upstream of the second growth reach here. The upstream end of the second growth reach was 75 m downstream of the cutbreak. The downstream end of the old-growth section was 75 m upstream of the cutbreak. Sampling frequency: Single year The study was conducted within nine reach-pair sites located within the McKenzie River Basin in the western Cascade Mountains of Oregon. Seven of the sites were located within the HJ Andrews Experimental Forest (HJA), a 6,400 ha research forest encompassing the entire Lookout Creek drainage basin. Cook Creek and Fritz Creek were located outside of the HJA. Cook Creek is a tributary of Blue River upstream of Blue River reservoir and Fritz Creek is a tributary of Deer Creek, which flows directly into the McKenzie River. Each pair consisted of two reaches: one within a section of stream with old-growth riparian forest, and another in a nearby section of stream bordered by second-growth riparian forest on at least one stream bank. Harvesting in the previously managed reaches occurred on just one stream bank in three reach pairs (MR404, LO701, and LO703) and on both banks for all other pairs. Sites were selected based on the presence of old-growth and second growth riparian forests close in proximity on the same stream (within 500 m). Having distinctly different forest types along two nearby sections of the same stream reduces inherent stream-to-stream environmental variability (e.g. temperature, gradient, geology, substrate, etc.) that often arises in comparisons between whole-stream systems in basins with managed versus unmanaged, late succession forests. Reaches ranged from 90-200 m and reaches within a reach pair were separated by a 90-325 m buffer section. Metrics of habitat and productivity relative to fish and salamander biomass in nine stream reach pairs were collected. Considering differences among streams and between reaches within each stream, relationships between both biotic and abiotic covariates and the biomass of coastal cutthroat trout (Onchorhynchus clarkii clarkii), coastal giant salamanders (Dicamptodon tenebrosus) and total vertebrates (fish and salamanders) were evaluated. Five of the six fish-bearing stream reach pairs originally surveyed by Murphy and Hall (1981) were visited to determine how stream conditions, benthic biofilms, invertebrate predators, and ultimately resident coastal cutthroat trout have responded to nearly four decades of riparian forest regeneration. Using the upstream reference reaches identified by Murphy (1979), which were bordered by old-growth riparian forests, this design is similar to a before-after control-impact study with riparian regeneration as the treatment. The same study reaches were sampled and evaluated how 40 years of riparian regeneration influenced our response variables. Citation: Kaylor, Matthew J.; Warren, Dana R. 2017.

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 AS01001 Fish and salamander surveys: AS01001.csv 214116 ab16e7eaba1967bc4e26a4cf861718a6 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=AS01001_v1.csv 2014-08-04 2014-09-05 DBCODE FSDB Database Code char(5) AS010 FSDB Database Study Code ENTITY Entity number numeric(2,0) number 1 natural 1.0000 1.0000 SITE Site of survey char(6) COOK Cook Creek, a tributary of Blue River upstream of Blue River reservoir and north of HJ Andrews FRITZ Fritz Creek, a tributary of Deer Creek, which flows directly into the McKenzie River, NE of HJA LO701 Harvest block L701 on Lookout Creek LO703 Harvest block L703 on Lookout Creek MACK Mack Creek.
