Remeasured (or permanent) forest growth plots are used for a variety of purposes. By a remeasured plot we mean a plot where tagged trees are measured at successive time intervals for monitoring growth and development. Many activities that are integral parts of forest management rely on data from such plots, including the development and validation of forest growth and yield models, the documentation of changes in forest inventory, and the monitoring of forest health. A system for properly managing the data from these plots is essential to their eventual use.
