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.
This database contains a collection of regression equations to predict various biomass components for many plants of the Pacific Northwest based on common parameters such as diameter, height, and cover. Documentation, including sources of raw data and source publications, is provided for each equation.
