Abstract
Extensive forest surveys can be periodic or permanent, regional or national, can include midcycle updates or not, or use partial replacement of plots or not. Fifty-two combinations of these and other factors were evaluated, not solely on a statistical basis, but also on their perceived ability to meet various design and customer objectives. These criteria include survey cost, precision and reliability of the results, reporting and customer satisfaction, simplicity, and flexibility. Based on this evaluation of permanent and periodic surveys, we recommend that planners compare their current periodic design to a permanent national design, a permanent regional design, and each of the two with a midcycle update.
