Tracking planned and completed harvesting activities is a fundamental element of the webFRIS solution. Theoretically a user will create planned harvest activities (clear-cut and thinning) for many years into the future. Once these activities have been completed on the ground, users will flag the original planned activity as accomplished. webFRIS maintains the spatial and tabular data for both the planned event as well as the completed event so that comparisons between what was planned and what actually occurred can be made.

Business logic and topology rules are enforced on all harvest activities. A completed harvest activity automatically calculates the removals based on the process used and stores that information in an easy to access inventory removal table. The residual volumes are also calculated and remain as part of the stand level inventory. Automation of such rules improves the accuracy of the data and saves valuable time for the user.
