Estimates are based on a sample and are therefore subject to sampling error. Urban FIA is designed to provide reliable estimates at the population level (e.g., the city boundary). In general, with more specific estimates (e.g., publicly owned versus all ownerships, specific species, single class of theme, etc.) sampling errors will increase and the reliability of the estimate will decrease. Sampling errors should be considered in any application of the estimates presented here. While sampling errors are not included per se, the number of plots used in a given estimate gives somewhat of an indication of the estimate’s reliability.

More information about Urban Forest Inventory and Analysis is available from the USDA Forest Service. For assistance evaluating the reliability of the estimates or other questions about uses of the data, contact the USDA Forest Service representative for data consultations and requests in your region.
