Sav 1 = Savannah habitat with high military use, Rip 1 = Riparian habitat with high military use, Upl 
1 = Upland habitat with high military use, Sav 2 = Savannah habitat with low military use. Rip 2 = 
Riparian habitat with low military use, and Upl 2 = Upland habitat with low military use. Texas map

Surveys were conducted via line transect sampling 
(Burnham et al., 1980; Seber, 1982 Ratti et ah, 1983). 
Each area survey consisted of three 5-km transects along 
which five sampling stations were placed at 1.0-km in¬ 
tervals. Each transect was sampled daily for a three-day 
period, giving a possible 45 trap nights per transect per 
sampling period. Each sampling station consisted of 
Tomahawk® live traps of three different sizes: 51 cm X 
18 cm X 18 cm (#204), 66 cm X 23 cm X 23 cm (#205), 
and 81 cm X 25 cm X 30 cm (#207). Traps were placed 
at least 20 m from each other to minimize influence on 
each other. Further consideration in trap placement in¬ 
volved setting each trap in similar vegetation types. Be¬ 
cause the animals being sampled were freely mobile and 
the microhabitat in which traps were placed was homo¬ 
geneous, it is probable that different individuals would 
be involved each day, and the arrangement of the traps 
could remain fixed (Begon, 1979). Traps were baited 
with fish-based canned cat food, then checked the fol¬ 
lowing three days. Bait was replaced on the second day, 
or as necessary after captures or disturbance of the traps.
