406-982-3301 Art.McKee@umontana.edu Creator 2011-09-14 Seasonal and annual rates of litterfall have been sampled at 6 permanent plots picked to represent a range of habitats and elevations. To assess variation in litterfall and decomposition and its role in nutrient cycling across an environmental gradient of moisture and temperature. This study is to be incorporated with others in the western and northern US to study the relationship of climate and vegetation on litterfall rates and decomposition. primary productivity leaf area reference stands permanent plots litterfall primary production inorganic nutrients organic matter LTER controlled vocabulary Long-Term Ecological Research (LTER) Andrews Experimental Forest site thesaurus primary production inorganic nutrients organic matter LTER core research areas Data Use Agreement: The re-use of scientific data has the potential to greatly increase communication, collaboration and synthesis within and among disciplines, and thus is fostered, supported and encouraged.

Since 1990 litter has been collected in 6 traps 29 cm in diameter (0.066 m2). 6 traps randomly located on a diagonal grid across the 50m x 50m square plots. Litter collected every 3-6 weeks except in the winter at the highest elevation sites. Standing litter biomass estimated in 10-.1 m sq plots. RS13, RS14 are young growth forests; the rest are old-growth. Litter traps made of 2 x 4 inch wood frames 1 sq meter in area with nylon mosquito netting and support wire. Material oven dried at 70 deg C for at least 24 hr. Litter separated and weighed to nearest 0.01 g. 14 categories for sorting. From June 1978 on,"unattached needle weights. 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 TL00101 Litter fall, all sites 770606 - 810520: TL00101.csv 223160 ae72a8a8ba79954e4772c41a0d0c6c76 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=TL00101_v1.csv DATACODE Data set code char(4) Data set code STAND Alpha code for reference stand char(4) RS01 Reference Stand RS01, H.J.
