ScopePeriodically field measurements are taken to learn more about forest ecosystems, how they change over time, and what stressors may be adversely affecting them. Results from various inventories are assessed and used to develop statewide and local forest management plans.

Forest Indicators
Forest indicators are elements of the ecosystem that can be measured and used to estimate the condition of or trends and patterns that are in progress in the structure of forests. Forest health is often measured  through tree health and includes variables such as growth, crown health, presence or absence of stress agents, and any forest responses to environmental changes.
