Abstract: From June 2010 to August 2011, four different camera trap placement patterns, i.e., line pattern, cross pattern, random pattern, and same elevation pattern, were adopted to monitor the mammal resources in the Gutianshan National Nature Reserve. A total of 2551 mammals independent photographs (IP) were taken, among which, 1240 were of recognized mammal IP, accounting for 48.6% of the total, 1167 were of unrecognized mammal IP, accounting for 458%, and 144 were of invalid IP, accounting for 5.6%. Fourteen mammal species were identified, belonging to 9 families of 4 orders. The mammals included black muntjac (Muntiacus crinifrons), the national I class protective animal in China, and serow (Naemorhedus sumatraensis) and black bear (Selenarctos thibetanus), the national I class protective animals in China. According to the curve of speciesmonitoring day, it was found that the number of the mammal species tended to be stable after six months monitoring, and thus, it could be more appropriate to monitor the mammal resources with six months as a cycle. As for the four different camera trap placement patterns, there were no significant differences in trapping mammals species number and trapping rate among the line pattern, cross pattern, and random pattern (P>0.05), but the three patterns had significant difference (P<0.01) with same elevation pattern. Due to its grid model, welldistributed camera, and arrangement specifications, same elevation pattern operated better than the other three patterns.
