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.
While substantial efforts are made to ensure the accuracy of data and documentation, complete accuracy of data sets cannot be guaranteed. All data are made available "as is". The Andrews LTER shall not be liable for damages resulting from any use or misinterpretation of data sets.
To examine the seasonal and successional patterns of respiration losses for four species (Abies amabilis, Pseudotsuga menziesii, Thuja plicata, Tsuga heterophylla), and two positions (top and side). Periodically this set of logs is examined for respirations rates.
