Methods
Life forms: rodents,other small mammals
Sites: 2
Site length: 120
Site width: 60
Sampling methods: quadrat,baited,Sherman traps
Sample size: 487 individuals
Years: 2007 - 2011
Nets or traps: 98
Net or trap nights: 13818
Sampling comments: two "permanent square grids (60 x 60 m)... situated more than 200 m apart... Each grid consisted of seven parallel lines, 10 m apart, with trapping stations also 10 m apart (i.e. a total of 49 trapping stations per grid). Trapping was conducted with Sherman LFA live traps... baited with peanut butter"; there were 27,636 trap nights total across two treatments, so half are assumed to apply to this one
