Barrier Island Herpetofauna 
151 
animals (Gibbons and Coker 1978). For example, the data points show- 
ing the relationship between woodland area and number of species on the 
two islands fall along the same regression lines generated by similar data 
from eight other islands (Fig. 1). 
Fig. 1. Relationship between woodland area (based on standard topographic 
maps) habitable by reptiles and amphibians and actual number of species 
present. Linear regression equations based on nine Atlantic Coast barrier 
islands, including Kiawah, are highly significant as reported in Gibbons and 
Coker (1978). Capers Island data points fall near predicted regression lines.
