    The USDA Forest Service's National Woodland Owner Survey (NWOS) is conducted to better understand the attitudes and behaviors of private forest ownerships, which control more than half of US forestland. Inferences about the populations of interest should be based on theoretically sound estimation procedures. A recent review of the procedures disclosed an error in the application of estimation used in the NWOS. These issues are addressed and resolved in this article. The NWOS is administered to ownerships that contain a sample point determined to be forested and privately owned. The random selection of the sample points results in selection of ownerships with probability proportional to area of forestland owned. Inferences from survey results, including numbers of ownerships, area of forestland and associated variances, can be made using appropriate techniques, such as the Hansen-Hurwitz Estimator.
