(541) 737-8480 lterweb@lists.oregonstate.edu http://andrewsforest.oregonstate.edu/ Field Methods - CF021 To capture seasonal streamflow and precipitation signals weekly stream and precipitation samples were collected from May 2022 to May 2023. Stream samples were collected in the middle of the stream during low flow conditions and within a wading distance from banks during high flow conditions. Two samples were collected from each site, filtered (0.45 µm), and split: one acidified for cations, the other un-acidified for anions. Composite precipitation samples were collected from a Stratus Precision Rain gauge (Stratus, US) at PRIMET. Laboratory Methods - CF021 Samples were analyzed for cations (Si4+, Ca2+, Mg2+, K+, and Na+) using a Spectro ARCOS MultiView (AMETEK, Czech Republic) equipped with an optical emission spectrometer with true radial or axial observation of inductively coupled plasma (ICP-OES), and anions (Cl- and SO42-) using a Dione Aquion Ion Chromatography (IC) System (ThermoFisher Scientific, US). All solutes are reported in mg/l (ppm) with an analytical uncertainty of ± 5%). Sampling frequency: Approximately weekly To examine spatiotemporal patterns in stream chemistry, we sampled 10 sites across the Lookout Creek catchment. Five tributary stream sites were selected Cold, Longer, Mack, Nostoc, and McRae Creeks. Drainage areas of these sub-catchments range from 0.69 km2 to 15.63 km2. Five additional sites were established roughly below the confluence of each tributary along the main stem of Lookout Creek with drainage areas ranging from 5.53 km2 to 62.42 km2.

Bell david.bell@usda.gov david.bell@oregonstate.edu https://lemma.forestry.oregonstate.edu/about/david-bell 0000-0002-2673-5836 Principal Investigator The H.J. 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: DEB2025755 National Science Foundation https://ror.org/021nxhr62 DEB2025755 https://www.nsf.gov/awardsearch/showAward?AWD_ID=2025755 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.
