CHAPTER IV: WILDLIFE HABITATS FOR MISSISSIPPI’S SGCN,
THREATS AND CONSERVATION ACTIONS^289
R ock outcrops and caves are localized features of the landscape, which do not fit within other habitat
categories, but need to be included in the classification to insure representation. These unique landscape
features provide habitat for certain animals.
This type includes two subtypes: 17.1 Rock Outcrops and 17.2 Caves.
GENERAL CONDITION
There is currently no conservation protection for rock outcrops or caves in Mississippi. Many of these
are on private lands and funding for protection (i.e.- gating of caves, security from public intrusion) is
limited. As a result, human disturbances such as noise, vandalism, and fires in caves are common place
and detrimental to the species residing there. Natural disturbances, such as cave-ins are also damaging to
species reliant on this habitat type. Knowledge regarding the condition of caves and rock outcrops is
hindered due to a lack of monitoring and communication with private land holders.
17.1 Rock Outcrops
Value to SGCN - 12
Rank - 26th of 29 of Inland Terrestrial Complexes
(Terrestrial, Wetland, Subterranean and Anthropogenic)
DESCRIPTION
The soil mantle of the gulf coastal plain is derived largely from
sedimentary strata deposition when the state was submerged
under a great sea. Most of the landscape supports deep soils that developed from these sedimentary
materials. Few sandstone and limestone rock layers exist near the ground surface and only rarely do
they outcrop. They mainly occur along steep hill slopes, ravines or river channels where soils have
eroded away. Some of the regions containing rock outcrops include the Tennessee River hills, Jackson
prairie and loess bluffs. Although of minor extent, the rock outcrops provide quality habitat for several
species of animals. Chalk outcrops are commonly found in the blackbelt prairie, but they are not known
to have any special significance as habitat for animals.
