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.

ABSTRACT:
	This data set is used to document the changes in external characteristics, density, nutrient content, and form of carbon associated with various decay classes and ages of logs and snags. The pieces that have been dated form the basis for a chronosequence. All the pieces sampled are used to define the characteristics of decay classes. These classes are used in turn to convert the external dimension data in TD012 to estimates of mass and nutrient stores.
