 Significant differences also were detected for carnivore sighting frequencies between Late Secondary 

 Forest without Gardens, Late Secondary Forest with Gardens, and Combined/Early Secondary Forest 

 (mean sighting frequencies were 10.2 individuals/10,000 km, 3.4/10,000 km, and 0.9/10,000 km, 

 respectively; x^ approximation = 6.2482, d.f. = 2, P = 0.0440; Table 4-1). No significant 

 differences in sighting frequencies were detected between forest successional stages for marsupials and 

 edentates (P = 0.9100), rodents (P = 0.0954), or artiodactyls (P = 0.4337). 



Game versus nongame taxa . Significant differences were detected for game bird sighting 

 frequencies between Late Secondary Forest without Gardens, Late Secondary Forest with Gardens, and 

 Combined/Early Secondary Forest (mean sighting frequencies were 4.8 individuals/ 10,000 km, 

 1.2/10,000 km, and 5.8/10,000 km, respectively; x^ approximation = 7.2947, d.f. = 2, P = 0.0261; 

 Table 4-1). No significant differences in sighting frequencies were detected between forest successional 

 stages for game mammals (P = 0.1972), nongame mammals (P = 0.1752), or nongame birds (P = 

 0.1994). 

 Population Density Estimates 



The number of wildlife sightings were sufficient to calculate several population density 

 estimates, but not sufficient to justify a statistical analysis of population density estimates among the 

 three successional stages of forest. In the following section, as in the previous section, the data for 

 population density estimates were summarized by species, taxonomic group, and game and nongame 

 birds and mammals. 



Species . Among mammals, the squirrel was the most abundant species and had a higher 

 population density in Late Secondary Forest without Gardens (10.3 individuals/km^) than in Late 

 Secondary Forest with Gardens (7.2 individuals/km^) or Combined/Early Secondary Forest (4.5 

 individuals/km-; Table 4-2). The plain chachalaca was the most abundant bird and had a higher 

 population density in Combined/Early Secondary Forest (20.3 individuals/km^) than in the other 

 successional stages.
