1. Historical versus Current Distribution. Louisiana slimy salamanders (Plethodon kisatchie) were described by Highton et al. (1989) as a member of the slimy salamander (P. glutinosus) species complex. Most similar to Sequoyah slimy salamanders (P. sequoyah), Louisiana slimy salamanders are known from the hill parishes of north-central Louisiana (Dundee and Rossman, 1989; Highton et al., 1989). They were first recorded in central Louisiana by Wilson (1966), and their known range was expanded by Warner (1971) and Boundy (1994a, 1998). Their historical distribution is unknown.
2. Historical versus Current Abundance. Not common, but well established in central Louisiana (Warner, 1971). Historical abundance is unknown.
3. Life History Features. Little is known of the life history of Louisiana slimy salamanders. Life history features presumably are similar to that of related forms.
A. Breeding. Reproduction is terrestrial.
i. Breeding migrations. Unknown.
ii. Breeding habitat. Breeding habitat is unknown.
i. Egg deposition sites. Unknown.
ii. Clutch size. Unknown; there are no reports of egg number or size.
C. Direct Development. The hatching period probably is around mid autumn (Dundee and Rossman, 1989).
D. Juvenile Habitat. Same as adult habitat.
E. Adult Habitat. Hardwood forests (Dundee and Rossman, 1989), but they also occur in forests that are composed primarily of pines (Warner, 1971).
F. Home Range Size. Unknown.
G. Territories. Territorial behavior has been undescribed.
H. Aestivation/Avoiding Dessication. Aestivation is unreported. Animals likely avoid dessicating conditions by moving under cover objects or into burrows.
I. Seasonal Migrations. Unknown.
J. Torpor (Hibernation). Unreported.
K. Interspecific Associations/Exclusions. May be sympatric with southern red-backed salamanders (P. serratus).
L. Age/Size at Reproductive Maturity. Adults typically range in size from 46–70 mm SVL (Warner, 1971).
M. Longevity. Unknown.
N. Feeding Behavior. Prey likely consists of small invertebrates such as worms, insects, and spiders.
O. Predators. Unknown.
P. Anti-Predator Mechanisms. Nocturnal. All members of the genus Plethodon produce noxious skin secretions (Brodie, 1977). When handled, Louisiana slimy salamanders, like other members of the glutinosus group, release an adhesive secretion (Dundee and Rossman, 1989).
Q. Diseases. Unknown.
R. Parasites. Rabalais (1970) reported trematodes from a sample that contained both Louisiana slimy salamanders and Mississippi slimy salamanders (P. mississippi).
4. Conservation. Louisiana slimy salamanders are found in the hill parishes of north-central Louisiana, where they are well established but not common.
