Nash benjamin.nash@usda.gov Other Researcher Benjamin E. Nash benjamin.nash@usda.gov Method Contact 1000-01-01 With an increase in emphasis on monitoring climate change impacts and change in the form of precipitation at HJ Andrews Experimental Forest, snow data collection within our climate monitoring program, a snow course to document depths of snow was designed around a dispersed sampling scheme rather than a point intensive scheme as previously employed in the historic Reference Stand snow course. Primary objectives are to document the presence/absence of snow, snow depth, and time of melt-off. Snow depths are verified using stakes placed near the road to allow for routine and frequent observation. Stakes are placed at different locations, elevations and aspects in paired forested/open sites. Time-lapse cameras were deployed at all the stakes to allow for daily measurements beginning in fall 2014. Truthing of points with snow core sampling for snow moisture content (snow water equivalent) is done when possible, usually 1-2 times per year. Cameras are set to take 3 readings per day (09:00, 12:00, 15:00 PST). One snow depth and coverage is extracted from the images per stake per day. Additionally, snow water equivalence (SWE) and snow depth are measured in high precision at a few of the Benchmark Meteorological Stations (BMS). These latter data streams were stored in MS001, but were migrated to MS007 in 2025. hydrology climatology microclimate precipitation snow water equivalence snow depth reference stands modeling canopy gaps LTER controlled vocabulary forest management Andrews Experimental Forest site thesaurus The historic Reference Stand snow course was conducted throughout the 1980's and 1990's. The first measurement listed for a year is generally the first measurable snow of that year. However, the data suffers from not knowing the difference between no snow on the ground and no measurement of snow which makes the determination of snow melt-off difficult or impossible. Reference Stands with some snow measurements include RS03, RS04, RS05, RS12, RS13, RS14, RS18, RS26, and TS38. After 1993 only data from RS04 and two reference stands from the Wildcat RNA (RS13, RS14) are collected. All measurements were discontinued in 2003. Related FilesTitle: H.J.

A general text search is also available. https://hjandrews.shinyapps.io/im_methods_history/ Precipitation and melting snow runoff are measured by a tipping bucket with tips summarized in 5 minute intervals. General installation: The lysmeter collection pan was constructed from 2 x 12s and plywood. The pan was covered with hyplon (white vinyl polymer), and a bathtub drain installed in one corner. The pan was installed on the ground surface and was leveled such that the collected water would flow to the corner with the drain. The water is then directed to a tipping bucket (TB) in the basement of the structure by pvc pipe which is buried to prevent freezing. The final deminsions of the lysimeter pan are 92" x 93" x 12", so a volume of water equal to .01" of ppt is 1.4032 L. The Campbell data logger records the Tipping Bucket snow lysimeter tips (.01" of ppt/snowmelt input). An electromagnetic counter acts as a check to recorded tips. Sensors are connected to the data logger through a Campbell wiring panel.

A general text search is also available. https://hjandrews.shinyapps.io/im_methods_history/ Snow water equivalence (SWE) and snow depth are measured every 5 minutes. Due to high variability in readings, particularly of snow depth, values may only be posted every hour for some data. Snow moisture is measured with a Park Mechanical pressure pillow and Druck pressure transducer. Snow depth is measured with a Campbell Scientific model SR50 sonic ranging snow depth sensor or Judd communications snow depth sensor. The snow depth sensor takes up to 10 readings, performs error checking and outputs a reading in mm every 5 minutes. Depth sensor measurement range is 0.5 to 10 meters. The snow sensor is mounted on a long pipe extending from the shelter. The snow pillow readings are instantaneous at 5 minute intervals. Campbell Scientific data logger is used. Snow moisture and snow depth are merged in the output files. Snow moisture is measured with a Park Mechanical pressure pillow and Druck pressure trandsducer. Snow depth is measured with a Campbell Scientific model SR50 sonic ranging snow depth sensor or Judd communications snow depth sensor. Campbell Scientific data loggers are used. Field Methods - MS007: Snow course Snow moisture and snow depth are measured with snow cores at 5 points across a transect (see entity 20). This station snow course (transect) is near the station and tries to follow a single contour. The average of these 5 points provides a check of the snow pillow and snow depth sensor. Snow depth is also measured at each corner of the station snow pillow using a permanently set graduated stake (pvc pipe). The average depth is converted to snow water equivalence using the density calculated from the station snow course. Mt Rose snow core sampler Field Methods - MS007: Road snow course A snow stake is established at each site with a metal fence post driven into the ground to support a 2" PVC pipe that slides over the post. Survey rod decals are placed on most of the PVC pipes except at lower elevation sites where shorter stakes are adequate and stream level metal guys are used as the calibration system. Slope and aspect are recorded for all sites, as well as the initial stake tare reading relative to the ground (not all stakes have zero at the ground level). Before 2014, depth measurements at the stake were recorded, and high and low depth values were visually estimated only. These data were routinely recorded at the stakes while driving to other field activities. Typically, the Upper Lookout stakes on Rd. 1506 and Rd. 350 stakes were read once every 3 weeks. The 1507 stakes were sampled only once or twice a year. A check sheet was established to keep the collected field data organized. In 2014, timelapse cameras (mounted on trees with a small overhanging shelter) were tested to capture daily images of the snow stakes. In 2015, they were deployed at all snow stake locations as the primary means of data collection, but not replacing in-person site visits and data collection with check sheets. The cameras are set up to capture 3 images a day at 09:00, 12:00, and 15:00 PST. One of the three images, usually 12:00 by default, is interpreted later during data entry for snow depth and snow cover. A special trip is also made at least once per year to collect snow water equivalent (SWE) measurements as a way of ground truthing the snow in the vicinity of the stake for snow moisture. The nearby snow stake is measured at the same time. SWE Measurements at each stake are conducted by taking three snow core measurements with the Mt. Rose or “federal” snow tube sampling equipment to establish a relationship between snowpack water equivalence and depth. The snow tube core sampler is pushed down to the soil surface interface, depth is recorded, and snow is extracted. The snow core is measured, any soil plug removed, and the core weighed on a spring balance, with the tare weight of the corer subtracted, and the actual snow weight is converted to millimeters of equivalent water. The snow tube sampling procedure generally follows the NRCS snow sampling procedure except only three cores are taken. If there is a complete snowpack around the snow stake, 3 points are taken in the immediate vicinity of the snow stake (3 points approximately 1 meter equidistant from stake) and averaged. If the snow coverage is patchy, core sample placement becomes more subjective with limited spots where a useful core can be sampled. In the NRCS snow course a particular point not having any snow would be recorded as zero, but here all of our ground truthing cores have some amount of snow because points are selected for representation of the density of the snow (and not for representative depth). The % snow cover is estimated from camera images to document snow patchiness. <para>Mt. Rose or “federal” snow core sampler. Note that a new snow core sampler was put into use on approximately March 1, 1999. The new scale can measure greater weights. Generally, comparable snow cores weigh less on the new scale in comparison to the older one.</para> <para>Wingscapes timelapse cameras, including Birdcam Pro WCB-00019 and TimelapseCam Pro WCT-00121, WCT-00122, and WCT-00126 with SD card and C or AA batteries, depending on the model.</para> Field Methods - MS007: Reference Stand snow course At each site, snow is sampled at 10 points along a transect at 5 meter intervals. In 1988 the number of points was reduced to 5 per site. The snow tube core sampler is pushed to soil surface interface, depth is recorded, and snow is extracted. The length of the snow core is measured as an indicator of snow compaction. The snow is weighed on a spring balance, the tare weight of the corer is subtracted, and actual snow weight is converted to inches of equivalent water. In Reference Stands 4,12,13,14 paired transects in closed forest and open areas are taken. An open site was added at RS03 and RS26 for 1 year (WY90). At RS04, the open canopy site was moved to the road beginning WY91. Throughout the 1990's only RS04 and Wildcat RNA sites (RS13, RS14 open-closed canopy pairs) are measured, and only RS13 and RS14 after 2000. These measurement s were discontinued in 2003. Mt. Rose or “federal” snow core sampler. Processing Procedures - MS007 The cameras are removed from the field at the end of the snow season (usually May). The files are downloaded to directories by snow year and stake (sitecode). An in-house C# program was written to allow a person to review and record data from each image. Data then undergo a suite of QA/QC procedures. The data are converted to metric units and flags are applied. Data Entry - MS007 The snow stake data from the field check sheets were originally entered into a spreadsheet. An in-house C# program was developed to make image interpretation and data entry easier for a quantity of images that can exceed 20,000 in each season. This program is used for sequencing images and entry from the field check sheets. Depth is entered in increments of 0.1 foot, and non-zero values less than 0.05 feet are interpreted as a ‘trace’ amount of snow. In some cases, high and low depths were estimated from the images as well, but this was discontinued following snow year 2017 due to its difficulty and low confidence in the numbers produced. Snow cover is considered only for the relevant open or closed canopy areas with consideration for site specific factors such as vegetation, roads, tracks from vehicles, field of view, camera angle and height, and “stake” well or mound. For example, the snow stake can accelerate melting (e.g. albedo effect), which creates a depression around the stake (i.e. “stake” well), or through wind, can cause a small snowdrift or snow to mound up around the stake, issues which are accounted for by assessing the area around the stake to compensate for its effects. Data obtained from blurry or obscured images (with variability in megapixels between camera models) is sometimes inferred when reasonable and flagged as Q (questionable or estimated) and left blank when not able to read. Quality Assurance - MS007 The time-lapse cameras are removed every summer (usually May) and reinstalled in fall (usually November), and because of this, the exact orientation of the cameras differs slightly from year to year. Efforts are made annually to maintain the snow stake sites, such as clearing vegetation, trimming low branches, etc., but there is always some environmental variability. A few stakes have been moved, which is indicated by the position attribute in the data. To ensure quality data, those assessing data in the field and processing snow stake images are trained by more experienced personnel and given guidance on visual interpretation and data entry. However, with assistance from a variety of personnel over the years, the human factor in interpretation, the difficulty in assessing percent cover from a vertical camera, the limits of equipment in winter conditions, and uncontrollable environmental variables, there is a degree of imprecision in the data that should be acknowledged. After data entry, there is a stepwise review that occurs on both the data entered online and through spreadsheets and programs by data managers and field personnel. The data is flagged and corrected for issues such as mistakes and typos, illogical values, and inconsistencies. The entry notes are also used to help flag data appropriately. The snow depth is eventually converted to metric units and made available. The snow images and data sheets are also archived. Quality Assurance - Fire effects on data The HJ Andrews Experimental Forest was affected by wildfires in 2020, 2023, and, to a lesser degree, 2024. Documentation is being developed that will describe the potential impacts on long-term records, provide the date ranges of direct impact, and describe specific site or data impacts. The use of the BURNED event_code was expanded to include wildfire, and a code was added to each relevant attribute flag to indicate when fire effects are visible in the data (P=Pyro). Measurement sites include recent clearcuts and adjacent old-growth stands in the H. J. Andrews and vicinity from Reference Stands at 430 -1450 meter elevation, and include two open-forest paired sites in the Wildcat Research Natural Area. Sampling frequency: daily Four Benchmark Meteorological Stations (BMS) and two second-level stations are included in the MS001 database. The Primary Meteorological and Vanilla Leaf Meteorological BMS are retained. Two new BMS are installed. In 1994, the Upper Lookout Meteorological Station was established at high elevation (4200 ft, ENE aspect) on clearcut L708 in the SE Andrews. In 1995 the Central Meteorological BMS was established at a centrally located site on clearcut L351 (3300 ft, WSW aspect) in the east-central Andrews. A GIS analysis of elevation and aspect indicated the average elevation (3170 ft., 966 m) and average aspect (267 degrees) of the Andrews Forest, and the Central Met Station was located to represent these general averages. Modifications are made to the Primary and Vanilla Leaf Stations to standardize measured variables, temporal resolution, methods, and instrumention across all BMS. Sites will be cleared and required openings maintained following standards of the National Weather Service, the LTER network, and where appropriate, the NADP network. Telemetering of all BMS was completed in 1996. Second-level stations (SLS) at the Hi-15 and WS 2 Climatic Station will continue to be maintained for measurement of precipitation, temperature, and other data to maintain continuity of historical records. These sites also follow established procedural standards. The BMS include meteorological measurement of air and soil temperature, relative humidity, calculated dew point temperature and vapor pressure deficit, wind speed and direction measurement, incoming solar radiation, photosynthetically active radiation (PAR), soil moisture, snow melt, and snow moisture and depth. Snow stakes were established starting at the Primary Met Station (430 meters elevation) and at approximately 150 meter elevation increments along Andrews Forest roads. Sites are established in open canopy/closed forest pairs, with stakes at each paired location as close together as possible. One stake is placed in a forest opening (no canopy interference with snow accumulation) and one stake is placed in an older forest (preferably an old growth stand). Before snow year 2015 that starts in fall 2014, observations of snow depth were made in person and not on any schedule. Since fall 2014, daily depths of snow in the vicinity of the snow stake are recorded from camera images. Snow water equivalent measurements (snow moisture content) are collected once or twice per year with 3 snow cores taken in the vicinity of the snow stake and averaged. The historic Reference Stand snow course included paired open and closed canopy locations within the Andrews Reference Stands and Wildcat RNA thermograph sites.

<para>The time-lapse cameras are removed every summer (usually May) and reinstalled in fall (usually November), and because of this, the exact orientation of the cameras differs slightly from year to year. Efforts are made annually to maintain the snow stake sites, such as clearing vegetation, trimming low branches, etc., but there is always some environmental variability. A few stakes have been moved, which is indicated by the position attribute in the data.</para> <para>To ensure quality data, those assessing data in the field and processing snow stake images are trained by more experienced personnel and given guidance on visual interpretation and data entry. However, with assistance from a variety of personnel over the years, the human factor in interpretation, the difficulty in assessing percent cover from a vertical camera, the limits of equipment in winter conditions, and uncontrollable environmental variables, there is a degree of imprecision in the data that should be acknowledged.</para> <para>After data entry, there is a stepwise review that occurs on both the data entered online and through spreadsheets and programs by data managers and field personnel. The data is flagged and corrected for issues such as mistakes and typos, illogical values, and inconsistencies. The entry notes are also used to help flag data appropriately. The snow depth is eventually converted to metric units and made available. The snow images and data sheets are also archived.</para>

The HJ Andrews Experimental Forest was affected by wildfires in 2020, 2023, and, to a lesser degree, 2024. Documentation is being developed that will describe the potential impacts on long-term records, provide the date ranges of direct impact, and describe specific site or data impacts. The use of the BURNED event_code was expanded to include wildfire, and a code was added to each relevant attribute flag to indicate when fire effects are visible in the data (P=Pyro).

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.
