(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - SP004 1. Field studies; monthly: There are 10 plots within each of the twenty sites. These consist of locations along a 50 meter transect 5 meters apart where the gas flux chambers are placed and soil samples taken. Soil respiration was measured using indicating soda lime with a mesh of 6/12 (Fisher #S201-3). The increase in weight is directly proportional to the amount of CO2 adsorbed during the incubation period. Thirty grams of soda lime was added to 8 oz glass jars fitted with gastight metal lids. They were heated uncovered for 8 hr at 100°C to remove moisture. At time 0 the jars were placed on metal mesh stands within a incubation chamber (3 gal plastic ice cream tubs with a 23.5 cm opening), the lids were removed and the chambers sealed into the soils. Twenty four hours later, the lids were placed back on the jars and returned to the laboratory where they were again dried (with lid off) at 100°C for 8 hr. At each site, there was one control jar used to determine background CO2 levels and the uptake of CO2 during drying (jar was placed in a sealed incubation vessel). At every other location along the transect, about 800 g of soil was collected from the top 10 cm of mineral soil and put into plastic bags. These soils were sieved through a 2 mm sieve and used for the laboratory analyses. In the field, maximum and minimum 24 hr air temperatures were recorded using max-min thermometers or by traces using small portable thermographs in plastic bags. In addition, air and soil temperatures were taken at the beginning and end of each field respiration period. 2. Field studies; July: At each of 10 plots within each site, there were two chambers placed; one to measure total soil respiration as was the case in the monthly samplings and one next to it in which a plastic sheet was installed just above the mineral soil. The plastic sheets were installed 24 hr before the start of the actual experiment. By comparing the CO2 released by the total soil including both litter and mineral soil and litter alone, the contribution of mineral soil (and roots) could be calculated. At each of the ten plots along the transect, 4.7 x 10 cm mineral soil cores were taken in the top 10 cm of mineral soil to measure bulk density. Another set of cores was used to estimate litter concentrations. Laboratory Methods - SP004 a. For laboratory respirations, 5 gr (wet weight) of 2 mm sieved soil was added to a 25 mL Erlenmeyer flask and sealed with a serum bottle stopper. After the flask was sealed, the flask was preincubation for at least 1 hr at 15°C prior to taking the first headspace measurement. A sample of the headspace was then taken and analyzed using a gas chromatograph fitted with a TCD detector; two hours later, a second reading was taken. The resulting data were normalized to incubation time and g dry weight. b. The methane oxidation experiments were conducted in much the same way as the respiration experiments except about 30 ppm methane was added to the incubation chambers and the flasks were incubated for one hour at 15°C. The reduction in methane was measured with a gas chromatograph fitted with a flame ionization detector. The same approach was taken with the nitrous oxide consumption but an electron capture detector was used. During the second July sampling denitrification potentials were measured by adding 5 g wet weight of sieved soil to a 25 mL Erlenmeyer flask which was stoppered and the headspace was purged with Ar for a minimum of 3 mins. at over 100 mL per min. Two mL of a sterile solution containing 10-3 M glucose and 10-3 M nitrate is injected through the stopper and an equal volume of headspace was removed. The flasks were incubated at 15°C for a least one hour before the first headspace sample is taken for N2O analysis. The sample is then incubated at the same temperature for two hours and a second headspace sample is taken using the ECD detector. During the second July, methane production measurements were also taken by purging the headspace of the flask with Ar before methane production was measured after at least a 1 hr preincubation period. c. Dissolved Organic Carbon (DOC) was determined by adding 10 gr of sieved soil to 30 mL DH20 within a 125 mL Erlenmeyer flask. The flasks were shaken on a rotary shaker for 1 hr at 22°C. The soil slurries were allowed to settle at 22°C for 1 hr and then 1.5 mL was removed and added to a 1.5 mL capped microfuge tube. The slurry was spun for 5 min. in a Beckman microfuge and 0.5 mL was removed and placed into a 0.5 mL microfuge tube and frozen for future analyses. DOC measurements were made on a Dormann Carbon Analyzer using 100 ppm standards to calibrate the instrument. d. Ten gr. sieved soil samples were used to measure extractable ammonium and mineralizable nitrogen. The extractable ammonium was measured by adding 50 mL of 2 M KCl to the soil in a 250 mL Erlenmeyer flask and then shaken on a rotary shaker for 1 hour at which time ammonium concentrations were determined using an Orion ammonium electrode. The minerlizable nitrogen was measured by adding 10 g of soil to a large 53 mL test tube that was then filled with DH20, sealed and incubated for 7 days at 40°C. Ammonium concentrations were determined in incubate soil slurries to which an equal volume of 4 M KCl was added. All of the above measurements except the DOCs were done in duplicate. e. Ten gr samples were dried for 8 hr at 80°C to determine dry wts. One of these was heated in a furnace to 280°C for at least 4 hr and reweighed to determine level of labile carbon present. They were then heated again to 550°C for a least 4 hr to determine SOM. The other dried sample was used to determine pHs by adding 10X wt./vol. water. See http://andrewsforest.oregonstate.edu/data/studies/sp004/sp004_sitedescription.pdf These sites were selected to give a wide representation of different microclimates and vegetation types found at the HJA. The microclimate sites were selected along a rough N/S gradient from the top of a ridge to the North to another ridge to the South. Another set was selected along an roughly E/W gradient which gave representative sites of different elevations and aspects including sites that were hot and dry and those that are typically wet and cold. Also included were sites near streams that experience cooling. The vegetation sites included clearcut sites, and regenerated sites of different age classes. In addition, we included a Sitka alder and a broad-leave maple site. Two types of studies were conducted; (1) monthly measurements of field respiration, temperature, moisture, laboratory respiration, soil organic matter by combustion to 550 C, labile carbon by combustion to 280 C, and dissolved organic carbon and (2) an extended measurements of other variables in addition to those normally measured during monthly studies. These were conducted at every other site along transects during the month of July 1992 and 1993. In July 1992, we measured mineralizable nitrogen, extractable ammonium, litter concentrations, litter respiration (separate from the normal total soil respirations taken monthly), and both nitrous oxide and methane consumption rates using gas concentrations approximately 10X ambient. In July 1993, we made the following changes from the 1992 protocol; bulk density was also measured as was denitrification potentials and methane production rates. The nitrous oxide and methane consumption experiments were dropped. Andrews Experimental Forest (HJA) -122.26172200 -122.10084700 44.28196400 44.19770400 1631 1631 meter 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 SP00401 Soil Characteristics and Microbial Variables - Full set: SP00401.csv 23987 2a239ce1f79ada82d929e32c4ebfac2a 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=SP00401_v2.csv STCODE Database code char(10) SP004 FSDB Database Study Code FORMAT Entity number numeric(1,0) number 1.000000 natural 1.0000 1.0000 SITE Permanent trace gas sites char(5) 10C Mid-elevation (south slope) 11C Riparian area 1C 1v control + high hot dry mc 1V High hot dry microclimate (mc) 2C North facing 2V North facing clear cut (mid-elevation) 2VC Control for 2v and 3v 3C Valley site near stream (no slope) 3V 15 year old doug-fir stand 4C Cool-wet high elevation (north slope) control for 6v. 4V 35 year old doug-fir stand 4VC Control for 4v 5C Site similar to 3c but higher 5V Big-leaf maple site 5VC Control for 5v 6C High-moisture site (north facing) 6V Sitka alder veg. site 7C Moisture mid-elevation (north facing veg. site) 8C High dry hot site (south facing ridge top) 9C Low elevation (north slope) cool moisture DATE Date samples collected (yyyymmdd) datetime YYYY-MM-DD 1.000000 7/13/1992 12:00:00 AM 7/7/1993 12:00:00 AM SAMPLOCA Location along transect where sample is taken char(2) Location along transect where sample is taken PH pH numeric(5,2) pH units 0.010000 real 3.6000 5.9400 P_MOIST Percent moisture (wet-dry/dry)x100 numeric(5,1) percent 0.100000 real 17.6000 200.3000 F_DRY_WT Wt fraction dry/wet wt soil numeric(5,3) number 0.001000 real 0.3330 0.8500 SOM Percent soil organic matter in mineral soil (by combustion at 550 C) numeric(5,1) percent 0.100000 real 7.4000 89.3000 EXTR_AMM Concentration of ammonium n extracted with 2m KCl numeric(6,3) micrograms per gram 0.001000 real 0.0000 4.9650 MIN_N Concentration ammonium n after incubation at 40 deg.
