Methods
Life forms: rodents,other small mammals

Sampling methods: quadrat,Sherman traps,Tomahawk traps

Sample size: 263 individuals

Years: 1987

Days: 15

Seasons: spring

Nets or traps: 196

Sampling comments: "Each 7 by 7 trapping grid had stations separated by 15 m, thus covering an area of 105 by 105 m (including a boundary strip of 7.5 m), or 1.1 ha. Grids were equipped with... one Sherman and one Tomahawk-like trap"
trapping was "for 5 consecutive nights" each month from September through NOvember
"traps were baited with rolled oats"
Chinchilla lanigera was entirey trapped with Tomahawks and all other rodents with Shermans
