Brief Site Description:

Koen Experimental Forest

Detailed Site Description:

Established in 1951, the Henry R. Koen Experimental Forest (Koen) located in northern Arkansas is covered mostly in oak-hickory upland hardwood forest and oak-pine stands. Named for Henry R. Koen, forest supervisor of the Ozark National Forest in the first half of the 20thcentury, the experimental forest was established to develop scientific principles for forest management. At 720 acres, the Koen is the smallest of the 19 experimental forests managed by Southern Research Station (SRS).
