(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - TD022 Once logs had been selected for sampling, they were marked with an aluminum tag and their location was plotted on a rough sketch map. This allowed us to resample many of these logs and apply the decomposition vector method to narrow uncertainties about decomposition rates. Dates of tree death or cutting were taken from fall scars and or living stumps (Harmon et al. 1986). In the case of logs added by harvest or thinning, we corroborated these dates by aging living stumps within the unit sampled. Fall scars and the upper portions of living stumps were removed with a chainsaw and air-dried. These cut surfaces were then sanded with fine grit sandpaper and examined under a binocular microscope at 10-X magnification. Rings formed after the scars were counted twice and if the counts differed were counted a third time. For each log sampled we noted key characteristics that could be used to define a decay class system. Physical characteristics recorded included: the presence of leaves, twigs, branches, bark cover on branches and boles, sloughing of wood, collapsing and spreading of the log (indicating the transition from round to elliptic form), degree of soil contact, friability or crushability of wood, color of wood, and if the branch stubs could be moved (Harmon et al 1987). Biological indicators such as moss cover, fungal fruiting bodies, or presence of insect galleries were also noted although past experience shows they are too variable at a local scale to be useful in separating decay classes (Harmon et al 1989). To determine rates of decomposition we determined the remaining mass of each log. Current mass remaining was determined from the current density and volume of the log. The current volume was determined by measuring the length and diameter systematically along the bole from the base to the top as well as the locations where cross-sections were removed. For each log segment defined by the end diameters or the cross-sections, we calculated the volume as a frustum of a cone (Harmon et al 1989). The current density of the wood and bark was determined by removing cross-sections along the length of each log. For sound trees we removed 3 to 4 cross-sections. In the case of extremely decomposed or very short logs, only 2 cross-sections were removed. For each cross-section the diameter, mean longitudinal thickness, circumference covered by bark, radial thickness of bark and mean radial depth of decay were recorded. Diameters were usually measured using a diameter tape, however, in the case of extremely old logs the cross-sections were too decomposed to be measured with this method. We therefore excavated very decayed cross-sections and used a ruler to measure the long and short axes of the cross-section from the remaining portions of the log. The total mass of the bark and wood for each cross-section was weighed on a portable electronic scale with a range of 1 to 6000 g (Ohaus Model CT6000), and then 50-200 g subsamples were removed to determine the moisture content. When cross-sections had a range of decay or moisture conditions, we took samples from the different areas in rough proportion to the area in each condition. These samples were weighed and then dried in an oven at 55 C until their mass was stable (usually 7 to 14 days). Total dry weight was calculated as the fraction of dry material in the subsamples multiplied by the total wet weight. The volume of the bark or wood was determined from the dimensional data recorded. Current density of bark or wood was calculated as the dry weight divided by the volume of the cross-section. The overall cross-sectional density was calculated similarly, but using the total dry weight and volume. The weighted mean density for each log was calculated. The densities from each cross-section in a log were weighted by their cross-sectional area, so that the smaller, upper cross-sections contributed less to the log average than the larger, lower cross-sections. <para>Statistics - TD022</para><para>The primary statistical analysis used for the chronosequence and time series data was linear regression. To calculate the decomposition rate constant, the estimated age of the logs was used as the independent variable and the density of the log (adjusted for fragmentation losses) was used as dependent variable. The form of the regression equation used to calculate the decomposition rate constant was: </para> <para>ln (Densityt)= ln (Density0) -k t, </para> <para>where ln is the natural logarithm of Densityt or Density0, the density at time t and 0, respectively and k which is the decomposition rate constant. In the case of time series that did not have enough sample times for regression analysis (N<3) we used a modification of the regression equation: </para> <para>-k = (ln [Densityt/Densityt-i])/i </para> where Densityt or Densityt-i, the density at time t and the initial sampling time t-i, respectively and i is the interval between samples. The values of k calculated were then averaged to estimate the overall species rate of decomposition. </para> <para>For logs sampled using the decomposition vector method, we also averaged the decomposition rates for the decay classes. However, rather than use a simple arithmetic average, we weighted the value of each decay class according to the length of time logs spend in each decay class. While we did not have exact information on the duration of each decay class for each species, the residence time in decay class 2 is typically twice that of decay class 1. The same geometric relationship generally holds for class 3 and 2. Class 4 and 5 are typically have the longest residence times, and these are approximately equal. As the weightings for the decay classes are relative, we therefore divided the total life span of a log such that decay classes 1-5 accounted for 4, 9, 17, 35, and 35% of the life span; respectively. Decomposition rates were assigned to the midpoints of each decay class’s age, a decomposition rate of 0 was assigned to year 0 and relative year 100 (when no decomposition would be expected) and rates of decomposition were interpolated between the decay class midpoints. We then used these observed and estimated decomposition rates to estimate the remaining mass for each relative year of the logs life span. To estimate the weighted average or integrated decomposition rate, we calculated the reciprocal of the sum of all the remaining masses. Essentially this is equivalent of determining the decomposition rate by knowing the steady-state store of logs (Log Mass[ss]) with a steady input of 1 unit of mass of logs: <para>K=1/Log Mass[ss]. </para> <para>While this approach is usually applied to field data (e.g., Sollins 1982), it can also be used to give the average decomposition rate from logs of different ages. </para> Sites in Rocky Mountains, Pacific Northwest, Mexico; specifically Sequoia National Park, Fraser Experimental National Park, Puerto Morelos, Quintana Roo, Mexico. http://andrewsforest.oregonstate.edu/pubs/webdocs/reports/decomp/study_areas.htm Sampling frequency: annually The chronosequence approach was used to determine decomposition rates from logs in which the sampling occurred only once. In a chronosequence one ages many pieces in various states of decay and examines how a parameter such as density changes through time. This is a substitution of space for time, and while not as precise as a time series experiment (where individual pieces are followed through time) it provides a good first approximation of decomposition rates (Harmon et al. 1998). For logs sampled using the chronosequence and/or decomposition vector methods individual logs were selected to represent as many ages or decay stages as possible. For decay classes we sought to have at least 3 replicates of each decay class. For chronosequences we also sought to have at least 3 replicates of each decay class, although to represent as even a distribution in ages as possible, some decay classes had more replicates. Logs were created from a range of processes, although for chronosequences we avoided the use of logs generated from snag fall. In the case of logs left as a result of harvest or thinning, we examined the state of decay to make sure it roughly corresponded to the time left on the ground. Pieces that were either too decayed or too sound were not used as they might have been added at a time other than the activity date noted in the records. Trees adjacent to logs that resulted from natural mortality were examined for the presence of scars that may have been created when the log fell. In the case of logs in very advanced stages of decomposition it was often impossible to find a tree fall scar or any other means to date the time of death. Priority was given to very decayed logs with the possibility of dating the time of death, however, some logs were selected without dates. To estimate the initial density of dead trees, we sampled a limited number of freshly killed, standing dead trees. For the most part these trees still had needles attached and it was likely that they died in the past year.

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 TD02201 Log and Snag Descriptions: TD02201.csv 36928 d987f7a336ef2b48d16d1a293c355484 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=TD02201_v2.csv 1982-09-01 1994-06-24 DBCODE FSDB Database Code char(5) TD022 FSDB Database Code TD022 (terrestrial decomposition) ENTITY Entity number numeric(2,0) number 1.000000 natural 1.0000 1.0000 STUDYID Study Id, matches those in TD12 and TV010 whenever possible char(4) EUS Eastern United States INTM Intermountain United States IRIR Russia; 1-st pair of letters describes the forest inventory enterprise, Ir=Irkutsk; 2-nd Pair Of Letters Describes The Region-"oblast'", Ir=Irkutsk KHKH KH=Kabarovsk inventory enterprise; kH=Khabarovs region-"oblast"; russia KRKR KR=Krasnoyarsk inventory enterprise; KR=Krasnoyarsk region-"oblast"; russia MEX Mexico MOSK Moscow region, Russia NNOV Nizhnii novgorod; Russia NSNS NS=NNvosibirsk inventory enterprise; NS=Novosibirsk region-"oblast"; Russia NSTM NS=Novosibirsk inventory enterprise; TM=Tiumenskaya "oblast"-region; Russia PNW Pacific Northwest, United States PSW Pacific Southwest, United States STAR EPA star project headed by Dr. Beverly Law STPB St.-Petersburg; Russia WINE Winema National Forest WRE Wind River Xxperimental Forest STAND Code for stand char(4) ME Metolius RNA RSF Rancho San Felipe, Puerto Morelos, Quintana Roo THUN WIND RIVER R.D.
