CHAPTER IV: WILDLIFE HABITATS FOR MISSISSIPPI’S SGCN,
THREATS AND CONSSERVATION ACTIONS^19812.2a. Small streams. Streams of this type are drainage basins of less than 75 square miles
and often occur in the headwaters of larger streams. These streams typically have extensive
canopy and low flow rates. Substrate, water depth and other microhabitat characteristics vary
among streams and among reaches within these streams.
12.2b. Medium streams. These drainage basins do not exceed 1,000 square miles. These
streams of this type typically have less canopy, higher flow rates and more microhabitat types
than small streams. Substrates vary from fine silt to boulders and bedrock under deep and
shallow runs, riffles, deep pools and backwater areas. These streams may also have periodically
inundated floodplains, which may be important for the survival of some species in the stream.
