Solute dynamics in the hyporheic mesocosm in Watershed 1 at the H.J. Andrews Experimental Forest, 2019-2020
We investigated biogeochemistry along a 12-m hyporheic mesocosm that allowed for controlled testing of seasonal and spatial water quality changes along a flowpath with fixed geometry and constant flow rate. Water quality profiles of oxygen, carbon, and nitrogen were measured at 1-m intervals along the mesocosm over multiple seasons. dissolved oxygen (DO) and temperature profiles were monitored on 18 dates between May 2019 through August 2020. Grab samples to monitor profiles of carbon, nitrogen, and various other solutes along the mesocosm were collected in December 2019 and August 2020 to provide more comprehensive biogeochemical analyses at time points when the dissolved oxygen (DO) and temperature profiles were at or near the maximum seasonal differences. Mesocosm monitoring ceased abruptly due to the Holiday Farm Fire, which burned from September through October 2020, cutting off personnel access and electrical power to the mesocosm facility.
Air Quality Index (AQI) data from PurpleAir sensor at H.J. Andrews Experimental Forest LTER
This dataset contains hourly air quality and meteorological measurements collected from a PurpleAir sensor deployed at the H.J. Andrews Experimental Forest Long Term Ecological Research (LTER) site. The data includes four variables: timestamp (in Pacific Time), relative humidity (%), temperature (°C), and particulate matter concentrations (PM2.5 in µg/m³ using the CF=1 correction factor). The sensor provides continuous monitoring of local air quality conditions, with particular focus on fine particulate matter that can impact ecosystem health and visibility. Data are recorded at hourly intervals and timestamped in ISO 8601 format with UTC offset. PM2.5 values are reported using PurpleAir's CF=1 (Correction Factor 1) algorithm, which is optimized for atmospheric particulate matter. This dataset supports long-term environmental monitoring objectives at the Andrews Forest LTER and provides baseline air quality data for research on atmospheric conditions, wildfire smoke impacts, and climate-ecosystem interactions in Pacific Northwest forest ecosystems.
Historical Records of the H.J. Andrews Experimental Forest Program, 1947 to present
This database contains historical records of the H.J. Andrews Experimental Forest (a U.S. Forest Service property near Blue River, OR, within the Willamette National Forest) consisting of three parts: 1.) inventory of the physical records and information about locating those physical records and three collections of digital records created from the physical records: 2.) records concerning the forest itself (HJATheForest), and 3.) records of the personal history of H.J. Andrews (HJATheMan).
Oral history transcripts from the H.J. Andrews Experimental Forest Program, 1996 to 2018
Oral history interviews have been conducted over the last two decades with members of the Andrews Forest community who provided valuable historical information about the program and related issues. On the occasion of the 50th anniversary of the experimental forest (1998), history professor Max Geier (Western Oregon University) conducted 33 interviews with individuals (or pairs of people) and five research groups from 1996-1998. About 20 years later (2013-2018) historian Sam Schmieding (Oregon State University) conducted an additional 10 oral histories, including some with people who had been interviewed by Geier 20 years earlier. Several additional relevant oral histories with people who have been important in the history of the Andrews Forest have been conducted and are also included in this collection. This data package includes an inventory and transcripts of these oral history interviews including brief biosketches of interviewees.
Headwater Stream Macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon, 2003-2004
Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon, U.S.A and used a paired-stream study design to examine if long term legacies of prior forest harvest existed for communities of stream macroinvertebrates. This study also examined correlations of macroinvertebrate life-history traits with site physical variables.
Nutrient and microbial characteristics of mountain stream fine benthic organic matter in the H.J. Andrews Experimental Forest, 1995 to 1996
Numerous studies have examined qualitative shifts in leaf litter composition in the early to middle stages of decomposition. (Suberkropp, Godshalk and Klug 1976, Petersen and Cummins 1974, Findlay and Arsuffi 1989) which have shown that changes in leaf species and composition lead to marked differences in microbial processing rates (Suberkropp and Klug 1976) and that leaf and woody debris decomposition rates are related to both litter C:N and extracellular enzyme activities (Taylor et al. 1989, Sinsabaugh et al. 1992, Sinsabaugh and Linkins 1993). Since most organic matter moves through streams as fine particulate organic matter (FPOM) (Sinsabaugh et al. 1992) it is a potentially important link between terrestrial and aquatic environments. Although there is increasing interest in understanding FPOM dynamics, there have been few studies of factors influencing stream sediment FBOM chemical or microbial characteristics.
Aquatic insect sampling in Lookout Creek at the H.J. Andrews Experimental Forest, 2001
The database contains data from samples collected during the summer of 2001 on aquatic macroinvertebrates along Lookout Creek. Three data tables comprise the database. The two larger tables contain the taxonomic composition and abundances from samples collected using small (0.25m2 ) emergence traps and pan traps (0.19m2). Taxonomic resolution differs by order; for some taxa we identified individuals to family, genus, and species, some to family and genus, and others to family only. A third small data table is a complete list of taxa from the three orders Ephemeroptera, Plecoptera, and Trichoptera.
Annual tree productivity in permanent plots within the H.J. Andrews Experimental Forest
Tree cores were taken from trees in permanent plots within the H.J. Andrews Experimental Forest to estimate annual bole biomass increment. The purpose of measuring this was to determine how many trees need to be sampled within a stand in order to determine NPP accurately. Increment cores were extracted from all trees greater than 5 cm diameter at breast height in each site and measured for annual growth increment (cm). This data was used to explore a method for using increment cores in combination with long-term permanent plots and remeasurement records to estimate annual bole biomass increment.
