Accounts

Accounts summarize stand attributes into summaries. Whereas treatments are applied to individual candidate harvest blocks, accounts are used to sum up the current and future forest conditions in a variety of different ways. There are a wide variety of account types that track aspatial, zonal, patch and route indicators (see Accounts). Accounts are established by definitions that are made in the PIN file or the accounts.csv input file.

Accounts always have detailed information for the indicator for every period in the planning horizon. Most accounts are represented by Targets (see the section called “Targets”) that provide controls over how the account is handled in the objective function of the goal programming formulation.

A very commonly used account type is a summary account. For example, a summary account could summarize the growing stock attribute for all records into an account describing the growing stock of the entire forest. As growing stock of forested blocks change through time, so will the summary account of the growing stock of the forest. Accounts can summarize any stand attribute. Accounts can be summaries of arbitrary geographic zones such as the entire forest, or individual compartments, watersheds or deer yards. Several attributes can be summarized into a single account or only certain blocks can contribute to an account. Other special Patchworks objects such as patches and road networks are summarized in specialized accounts.
