CHAPTER IV: WILDLIFE HABITATS FOR MISSISSIPPI’S SGCN,
THREATS AND CONSERVATION ACTIONS^226drainage. Each is a separate river emptying into the Mississippi Sound,
between the Pearl and Pascagoula rivers. All are blackwater streams. These
streams have not been as heavily impacted by human activity as streams in
some other areas of the state, although increased land development in the
southern part of the state is a threat to these systems.
CONDITION AND CONSERVATION STATUS
These streams have received fewer disturbances than streams in some other
areas of the state, although there may be impacts from industrial and residential
development, forestry and localized channelization of streams.
The coastal drainages are apparently secure in the state. They are less disturbed than some other
streams in the state. However, future development may increase negative impacts.
