suit of live-trapping efforts (Fig. 2). Fifty-five opos¬ 
sums, 31 raccoons, 30 striped skunks {Mephitis mephi¬ 
tis), 11 ringtails {Bassariscus astutus), 9 eastern 
woodrats ( Neotoma floridana), 6 feral cats {Felis catus), 
3 eastern spotted skunks {Spilogale putorius ), 2 east¬ 
ern cottontails (Sylvilagus floridanus), and 2 fox squir¬ 
rels {Sciurus niger) were captured during the survey. 
Total captures for each season were 35 for winter, 
44 for spring, 39 for summer, and 31 captures recorded 
for the autumn. Sav 2 had 38 total captures documented 
across seasons (Fig. 3 and 4), Sav 1 had 25 captures (Fig. 
5 and 6), Upl 1 had 25 captures (Fig. 7), Upl 2 had 17 
captures (Fig. 8), Rip 2 had 26 captures (Fig. 9), while 
Rip 1 had 18 captures reported (Fig. 10). Opossums, 
raccoons, and striped skunks comprised 78% of total 
captures. Number of captures by species, area, and sea¬ 
son is detailed in Table 1. 
Capture means were calculated for each species 
per area per season (Table 2) as well as for each species 
for each season (Fig. 11). Capture means varied for each 
season from 0.047 for winter and autumn to 0.058 for 
spring. Capture means for each species ranged from 
0.019 for opossums to 0.00068 for eastern cottontails 
and fox squirrels. 
Previously-captured animals (i.e., recaptures) ac¬ 
counted for 10 of the 149 total captures. Opossums 
comprised six recaptures of which three involved the 
same individual. Striped skunk recaptures numbered 
three while only one raccoon was recaptured. Areas and 
corresponding number of recaptures included three for 
Upl 1, three for Sav 2, two for Sav 1, one for Rip 1, one 
for Rip 2, and none for Upl 2. 
Large traps accounted for 60 of the 149 captures 
(ca. 40%), while medium and small traps accounted for 
50 (ca. 34%) and 39 (ca. 26%) of total captures, respec¬ 
tively (Table 3). Of the nine species captured, small and 
medium traps each captured six and large traps captured 
eight (Table 4). The eastern spotted skunk (/i=3) was 
captured only in small traps. 
Overall capture mean varied significantly among 
areas (w=211; dfr 5; F= 3.75; P<0.01). Sav 2 had the high¬ 
est capture mean (=0.092) while the lowest capture mean 
was reported from Upl 2 (=0.033). No significant dif¬ 
ference in capture mean was detected among trap sizes 
{n=633;df=2; E=1.17; P=0.738) or among days (n=211; 
dfr 2; E=0.304; P=0.738), transects («=211; dfr 2; 
F=2.41;P=0.095) or seasons (»=2U; dfr2;F=0A33; 
P= 0.730).
