Sampling comments: "The minimum convex polygon size of the camera survey areas was 43.2km2 for A and 35km2 for both B and C... we conducted camera trapping survey between October 2012 and January 2013 using a systematic grid 2 km2 covering all three different sites varied in land use patterns at 44 locations. We did not have large number of traps (15 traps)... Each grid had a minimum of one camera trap site with mean inter-trap distance of 1.7km Each camera was operated for 30 days amounting to a total effort of 1320 trap nights... surveys used fixed [Camera LtI Acorn 6210MC digital] cameras... left to operate for 24 h a day"
