541-597-4650 dave_perry38@msn.com Creator 2011-09-14 To test hypotheses concerning feedback mechamisms (competition and mortality) which effect the dynamics of plant population development. Specifically, to test if manipulation of site quality (through fertilization) or the variance in individual tree leaf area (through pruning) will produce changes in the dominance hierarchy and thus in the growth mode of stands as they approach self-thinning (mortality). communities populations plant ecology population dynamics stand density succession primary production growth fertilization fertilizer forests plants LTER controlled vocabulary Long-Term Ecological Research (LTER) Andrews Experimental Forest site thesaurus populations primary production LTER core research areas The changes listed below were made before moving to sql server: format 2 had the 1981 remeasurement and was renamed to tp882.old the new format 2 combines tp882 (1981), tp884 (1983), tp889 (1985), tp8812 (1987), and tp8815 (1996) into a single file. the 1993 remeasurement (rem93.dbf) in the old fsdb was not included because the field work was deficient.

(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - TP088 Thinning - density reduced to 15% and 25% of maximum stand density. Fertilization - area added at 50kg/ha/year until new September foliage contains 2% N. Additional applications to maintain this level. Pruning - the meet crown width criterion (see study plan). Height, diameter, and sapwood area will be measured for a sample of trees every second year. Mid-elevation sites in the Western Oregon Cascades of similar stand characteristics, 2 on north-facing, 2 on south-facing slopes. Four replications of 3 density levels each. In a split-plot design we will establish two urea fertilization treatments (fertilized and unfertilized) in each density level, and two pruning treatments (pruned and unpruned) in each fertilization treatment.This establishes 12 treatment combinations per replication.Within each treatment combination a 50 tree measurement plot will be established.

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 TP08801 Pre and Post-Thinning Tree Densities 1981: TP08801.csv 2281 2e26e00605dead1a3937a9ca933c7667 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=TP08801_v1.csv DATACODE Data set code char(5) Data set code FORMAT Format number numeric(1,0) number 1 natural 1.0000 1.0000 SITE Site identification code char(4) L701 UNIT L701 L107 UNIT L107 L111 UNIT L111 L405 UNIT L405 DENSITY Stocking density level char(1) C Control;no thinning within the stand M Medium;density was reduced to 25% of maximum stand density index L Low;density was reduced to 15% of maximum stand density index TMT Type of treatment applied to plots within stands char(2) F Fertilized PF Fertilized and pruned C Control P Pruned YEAR Year of data collection numeric(4,0) year (yyyy) 1 natural 1981.0000 1981.0000 PLOT15TR Number of trees in a density plot centered at a random distance and direction from tree # 15 numeric(2,0) number 1 whole 4.0000 34.0000 PLOT15ST Number of stumps in a density plot centered at a random distance and direction from tree # 15 numeric(2,0) number 1 whole 1.0000 57.0000 PLOT35TR Number of trees in a density plot centered at a random distance and direction from tree # 35 numeric(2,0) number 1 whole 3.0000 39.0000 PLOT35ST Number of stumps in a density plot centered at a random distance and direction from tree # 15 numeric(2,0) number 1 whole 3.0000 61.0000 PLOTSIZE Area of each circular density plot numeric(4,2) hectares 0.010000 real 0.0100 0.1000 CALCDENS Density as calculated by T.
