Forest cover by state and territory in the United States

(Redirected from Forest cover by state in the United States)

In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service.[2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured.[3][4]

This is only the total amount of timberland. Actual forest cover for each state may be significantly higher.[5][1]

  1. ^ The forest percent is the percent of land that is forested (excluding bodies of water). Data for Puerto Rico, the Virgin Islands, and Guam is from 2013. Data for the Northern Mariana Islands is from 2015. Data for American Samoa is from 2012. Data for the national capital of Washington, D.C. is from 2018.
  2. ^ There is a forest on Palmyra Atoll,[7] but there is no information about what percentage of land the forest covers.
  3. ^ The U.S. territories are American Samoa, Guam, Northern Mariana Islands, Puerto Rico and U.S. Virgin Islands. The U.S. Minor Outlying Islands are not counted.
  4. ^ The FIA defines the Southern region of the U.S. as Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia.
