Volume Estimation

The Forest Management Service Center provides expertise in estimating volume from logs and standing trees. Our staff provides regional volume estimators for other programs, such as the National Timber Cruising Program (NATCRS) and the Forest Vegetation Simulator (FVS). We provide volume estimation support with the National Volume Estimator Library (NVEL). The NVEL is a collection of the volume estimators the Forest Service uses.

The Service Center also provides support to validate volume estimators, including the current estimators or new estimators a Region might be considering. We provide training for designing a validation study, collecting the appropriate measurements, and the validation software to analyze the data.
