This resource update is a brief look at some of the basic

metrics that describe the status of and changes to forest

resources in Oklahoma. This information is based on field

data collected using the USDA Forest Service Forest

Inventory and Analysis (FIA) annualized sample design, and

it is updated yearly.

Oklahoma has 7,270 sample plots across the State, of which

2,329 are currently forested. Each year, about 10-20 percent

of these plots are visited and measured by field crews. Data

used in this update were accessed from the FIA database on

06/02/2022.
