The time and financial expenditures of the field work for large-scale inventories are usually not known, or only inadequately known. For the planning and the execution of inventories, the knowledge about the required time for important working stages is indispensable. If these basics are not available, it is difficult to employ personnel and material in a cost efficient way. In the following, the actual expenditures for the terrestrial survey and inquiries are presented in person-hours. The database was based on regular reports (working reports) by the survey team; salary and expense statements; as well as the time that it took to perform the most important working tasks at the sample plots. The time was recorded using a handheld computer. A detailed account of the time and financial expenditures in the second NFI can be found in ZINGGELER and HEROLD (1997).
