A total of 42 microclimate sensor suites were installed in July and August of 2022 distributed across RS01, RS08, RS15, WS02, WS09, WS01, HGBK. All sensor locations are within the Holiday Farm Fire footprint and within Permanent Sample Plots (PSPs). An additional sensor was placed within the Primary meteorological station (PRIMET) of the HJ Andrews Experimental Forest for comparison and calibration between open-air measurements. Sites are stratified across three treatment variables including 1) fire severity: high or low; 2) management: managed or unmanaged; 3) water balance: moister or drier topographic positions. This resulted in eight treatment blocks, each with 5 sensor suite replicates. Each microclimate site includes a suite of measurements: Hobo temperature and relative humidity sensor installed at 1.5m within a gill shield (recording at 30 minute interval), one TOMST TMS-4 temperature and soil moisture sensor was located within 1 m of plot center (recording at 15 minute interval). The TOMST sensors include air temperature sensors at 15cm, 2cm, and soil temperature at -6cm in soil near-surface. Soil moisture is measured across the ~10cm near surface zone. climatology forest dynamics successional dynamics LTER controlled vocabulary 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.

(541) 737-8480 lterweb@lists.oregonstate.edu http://andrewsforest.oregonstate.edu/ Field Methods - MV009 Microclimate sensor arrays are visited annually. HOBO Pro V2 sensor data are downloaded using a HOBO shuttle, and TOMST TMS-4 data are downloaded to a tablet or laptop using the TMS adapter and Lolly software. Any anomalous site conditions (i.e., broken/missing sensors) are recorded. Broken or missing sensors are replaced on the subsequent annual site visit. Permanent Plots - MV009 All microclimate sensor array locations are within PSP circular plots. Quality Assurance - MV009 Failed sensor values have been removed, but data are otherwise presented in raw format. Sampling frequency: 15 or 30 minute intervals Each selected site contains a microclimate sensor array consisting of a HOBO Pro V2 External Temperature/Relative Humidity Logger (U23-004) and a TOMST TMS-4 datalogger measuring temperature (15-cm, 2-cm, and -6cm relative to soil surface) and soil moisture (-10cm relative to soil surface). The HOBO Pro V2 is suspended on a 2-meter metal T-post with the external T/RH probe located within an Onset gill shield (M-RSA) at 1.5-meters relative to the soil surface. The TOMST TMS-4 is located within 50-cm of the base of the HOBO T-post. Sites are stratified across three treatment variables including 1) fire severity: high or low; 2) management: managed or unmanaged; 3) water balance: moister or drier topographic positions. This resulted in eight treatment blocks, each with 5 sensor suite replicates. Additionally, a single guild-shielded HOBO PRO V2 sensor was secured to the primary meteorological station (PRIMET) for comparison and calibration between open-air measurements. The HOBO Pro V2 records temperature (degree C) and relative humidity (%) at 30-minute time intervals synced on the hour (0:00 and 0:30). The TOMST TMS-4 records temperature (degree C) and soil moisture (electromagnetic pulse) at 15-minute time intervals synced to the hour (0:00, 0:15, 0:30, 0:45).

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.
