In most of our states fieldwork is completed by USDA Forest Service personnel alone or in some cases in conjunction and cooperation with State personnel. Forest Health data collection is also completed by Forest Service personnel, although State organizations generally have a more active role in the fieldwork.
The field Inventory crew individuals collect basic forest resource data; locate selected points on the ground from aerial photographs or other imagery; run compass lines and measures distances; make plot and tree measurements; identify all woody vegetation on selected plots; classify stands according to forest type, age, site index and various land use classes.
Field Inventory crew individuals count stumps on Inventory plots and contact landowners, county and state officials, and others to collect information on timber removals and to determine land ownership, ownership size, and ownership tenure.
