14(1982). Nosurveys were conducted in 1980, 1981, 
1985, 1986, or 1993-1995. 
Spotlight line #3 includes surveys from 1979-1996 
(Fig. 14). The number of raccoons seen per year ap¬ 
pears to be cyclic with a decrease noted from 1988 (« = 
4) to 1989 (« = 0) followed by a sharp increase from 
1991 (n = 0) to 1996 (n = 6). Average number of rac¬ 
coons documented per survey was 2.23. Number of rac¬ 
coons seen per survey ranged from 0 (1989 and 1991) 
to 6 (1996). No surveys were conducted in 1980 or 
1992-1995. 
Surveys from spotlight line #4 were conducted 
from 1987-1996 (Fig. 15). This survey is represented 
by two distinct peaks in raccoon abundance in 1990 (n = 
7) and 1993 (n = 6) both followed by years with no rac¬ 
coons sighted. Raccoons documented ranged from 0 
(1989,1992, and 1996) to 7 (1990). Average raccoons 
seen per survey was 2.14. No surveys of line #4 were 
conducted in 1991,1994, or 1995. 
Surveys of .spotlight lines #5 (Fig. 16) and #6 (Fig. 
17) were conducted from 1990-1996. A sharp decline 
in raccoons documented is evident from 1991 to 1993 
on line #5 as well as from 1993 to 1996 on line #6. 
Average number of raccoons documented were 2.0 for 
line #5 and 3.75 for spotlight line #6. 
Data from the six surveys were combined and 
graphed to depict average number of raccoons seen per 
24-km transect per year (Fig. 18). Raccoon abundance 
appears higher in 1978 ( = 8 raccoons documented per 
year), 1982 ( =9.8 raccoons documented per year) and 
1984 ( = 6.8 raccoons documented per year) with lower 
numbers recorded in 1985 ( = 0.6 raccoons documented 
per year) and 1996 ( = 1.7 raccoons documented per 
year). No consistency in raccoon trends is apparent
