Forests at a Glance…
The Forest Resource
Utah forests are as diverse as the landscape itself. Forest visitors from around the world, as well as locally, flock to the state’s renowned canyon lands and alpine getaways. While Utah is currently only 29% forested, these forests have high scenic value, as well as many other values, so it is important to track their condition. Inventory and monitoring efforts conducted by USDA Forest Service present a systematic compilation of forest statistics of the state. For example, the graph here presents a breakdown of forest cover, or forest type, on all land ownerships. Comprehensive Inventory of Utah’s Forest Resources, 1993 presents a detailed compilation of Forest Inventory and Analysis (FIA) work based on the most recent completed statewide inventory (O’Brien 1999). We began Annual Inventories in the state in 2000.

Plot Status and Current Activity

Field crews are collecting data on Forest Inventory plots and Forest Health plots across Utah annually. The FIA method consists of 3 inventory phases: a remotely sensed phase (P1) and 2 field phases (P2 and P3). Field work begins in early spring and proceeds into the fall as plots are completed or weather permits.
Number of Plots by Plot Type
Annually, there is on average 425 Phase 2 plots and 20 Phase 3 plots in Utah. Phase 3 plots are a subset of P2 plots. In addition to the variables taken on P2 plots, P3 plots collect additional data with an emphasis on forest health.
In addition to this site, other information related to Utah forest conditions may be found on the websites of federal and state cooperators. Click on the icons below to see what our partners are up to…
Data and Table Access
You may find standardized summary tables by going to– Annual Tables. Customized data summaries are available through FIA data retrieval systems.
Other Utah Reports
A record of previous statewide reporting efforts is shown in the table below. Note that other special reports, brochures, and data tables using FIA data, but not shown in the table, can be found in a comprehensive list at Utah’s Forest Resources.

Previously it was named the Intermountain Forest and Range Experiment Station or the Intermountain Research Station, hence the initials INT in the report number.
Inventory and Monitoring Information

For specific questions related to field procedures, current and past field manuals are available here. These manuals describe the details of plot establishment and description, forest inventory methods, and procedures used for each forest health indicator. Websites for forest health indicators give rationale for the indicator, as well as access to data, analytical procedures, and related publications.

For clients with a general interest in inventory and monitoring work elsewhere, we have compiled a short list of Inventory and Monitory on the Web. This list comprises agencies and entities with related interests in forest monitoring at various geographic scales, both within the U.S. and internationally, plus some recommended publications for those with a more technical interest in this subject.
