Field Methods - TD020
PVC Cylinders, 25 cm diameter and 25 cm tall, are mounted on logs in top and side positions. Drain holes have been installed on the top mounted cylinders to prevent waterlogging of the log. Periodically the cylinders are capped and CO2 evolved is trapped in 0.1 N NaOH solution. Because of the variation in respiration rate, the amount of solution has varied from 20 to 80 ml. Exposed solutions are then processed by first adding excess BaCl solution, filtering the precipitate and then titrating with 0.1 N HCl. Solutions vary in the degree they absorb CO2. The final calculated value has been adjusted to reflect the changes in trap efficiency brought about by CO2-absorption.
A new method of CO2 capture was begun in 1992. Approximately 30 g of oven dry 6-12 mesh Sodalime was exposed within the closed chambers for the same 24 hour period. After this period the sodalime was oven dried at 100 degrees for eight hours and the weight gain was used to calculate the amount of CO2 evolved. During the period of use there was no change in absorption efficiency.
For details see http://andrewsforest.oregonstate.edu/data/studies/td014/td014_sitedescription.pdf Sampling frequency: monthly
Split plot in time, with six blocks (sites 1-6), four species of log as the main plot treatment, top and side cylinders as subplot treatments. The same log is repeatedly sampled on a monthly basis.

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: 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.
