The Demise of the Longleaf Pine Ecosystem
The demise of the longleaf pine ecosystems began soon after European settlement, although some native tribes cleared land for agriculture. With settlement, logging, agricultural clearing, fire suppression, conversion to fast-growing loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii var. elliottii Engelm) plantations, and natural regeneration failures due to feral hogs all contributed to the decline of longleaf pine forests throughout the Coastal Plain. The degradation of the longleaf pine ecosystems was typically compounded as illustrated for the Lower Gulf Coastal Plain of Georgia and Florida in the vicinity of Thomasville and Tallahassee.
Decline of longleaf pine ecosystems in the Lower Gulf Coastal Plain
Native American
activities, including the use of fire to enhance game populations
and clearing for agriculture, were prevalent in the southeastern
United States prior to European settlement in the late 1700s.
There is substantial evidence that many native tribes and early
European settlers frequently burned the forests with annual, dormant
season surface fires to improve livestock forage and turpentine
production (see picture on right). By the early to mid
1800s, large cotton plantations were common on the more clayey
and loamy, fertile soils of the region, while the more sandy,
and relatively less fertile areas of southwestern Georgia were
farmed in small tracts, or left as forestland or rangeland. With
the demise of the cotton industry after the Civil War, northern
speculators purchased most of the large cotton plantations. Many
of these landowners became interested in game bird hunting, primarily
for bobwhite quail (Colinus virginianus). At the same time,
areas not in cotton production were turpentined (see picture at
left) or commercially clearcut. Because the landscape became highly
fragmented and interest in quail management increased during the
early twentieth century, many of these plantations continued the
use of dormant season prescribed surface fires to prevent hardwood
regeneration and to promote game bird habitat. During this period,
the use of plowed fire breaks to limit the extent of prescribed
surface fires generally increased. Finally, modern farming practices
such as center-pivot irrigation, has increased agricultural production,
making it more profitable to grow cotton or peanuts on an annual
basis.
