Table 8. Seasonal abundance of Palaemonetes paludosus at stations where the 
species was collected at least once during the study. Data are expressed 
as percentage of stations at which the species was abundant or absent. 
Data from 1982 and 1983 have been combined.

troglodytes , Fallicambarus uhleri ) were each found in only one location. 
No brooding females of any species were collected. 
Procambarus blandingii was commonly encountered throughout 
the refuge in habitats ranging from vegetated margins of Lake Marion 
to ditches, impoundments, and shaded swamps. Juveniles were found in 
all seasons, but were particularly abundant in June. This species has 
been reported from lentic and lotic sites in southern North Carolina and 
from the Santee River to the Pee Dee River in South Carolina. Its type 
locality is in Kershaw County, S.C. (Hobbs 1974). 
Procambarus hirsutus was found only in one sample taken in 
emergent vegetation along the edge of Lake Marion. Because immature 
specimens are easily confused with those of P. blandingii , this species 
may be more widespread in the refuge than this one sample indicates. 
Procambarus hirsutus has been previously reported from streams in the 
Edisto, Salkehatchie, and Savannah drainage systems in South Carolina. 
Its type locality is Barnwell County, S.C. (Hobbs 1958a). 
Procambarus troglodytes was found in one location that consisted 
of a series of small unshaded puddles resulting from excavation work 
less than 100 m from Lake Marion. Individuals were abundant in June 
in these puddles, where they constructed large chimneys. Procambarus 
blandingii occurred in some puddles and an impoundment within 30 m 
of the puddles used by P. troglodytes ; however, neither species was 
collected from a puddle inhabited by the other. Procambarus troglodytes 
occurs in lentic and lotic habitats between the Altamaha River in 
Georgia and the Pee Dee River in South Carolina (Hobbs 1974). 
Fallicambarus uhleri was found in only one locality, a borrow pit, 
and in small numbers. Procambarus blandingii occurred in much greater
