Summary

We provide four datasets: Mark recapture and trapping effort, Grid layout, Chew cards, and Trail camera validation. Mark recapture and trapping effort has one row for every live-trap night, including the unique grid identification code, date of trap check, cumulative rain amount from the 24-hr period before the trap check, unique trap identification, trap status, unique individual rat identification (ID) and associated morphometrics, and rat fate. Grid layout includes the unique grid identification code, unique trap identification, and GPS coordinates of the traps. Chew cards has one row for every chew-card night, including the unique grid identification code, date of chew-card check, unique chew-card identification, and whether the [...]

Purpose

Rats (Rattus spp.) have become established on over 80% of the world’s islands and now represent one of the most damaging and expensive biological invaders. Effective rat control tools exist but require accurate population density estimates to inform treatment timing and effort and to assess treatment efficacy. These data were collected to model species density and occupancy. Appropriate use of the live trap data are for estimation of detection probabilities and density. Appropriate use of the chew cards are estimating relative abundance of small mammals.
