Located in the Lower Mississippi Riverine Forest ecoregion, Arkansas Post includes 255 acres of prairie and forests and 54 acres of landscaped grounds. The area is in the Delta Region of south-eastern Arkansas.
Arkansas Post does not experience many wildland fires, but fire’s role in this ecosystem is still ecologically important today. When fire managers conduct prescribed fires, their goal is to maintain and replicate the role of historical fire in the ecosystem.
Fire Ecology of Arkansas Post
Prescribed fires are a part of the process to remove invasive plants from the ecosystem. They are a key in the maintenance of native plant communities and wildlife habitats.
When a group of plants lives in the same area, they are classified as a vegetative community. Arkansas Post’s vegetative communities include:
Terrace hardwoods: elm, ash, cottonwood
Bottomland hardwoods: hackberry, sweetgum, cedar, oak
Former agricultural fields (old-field succession): sawtooth blackberry, sugarberry, honeylocust
Aquatic communities: bald cypress, water tupelo, American lotus
