An investigation of the rat pest problem in Queensland canefields: 5. Populations

Abstract

Line-trapping, elimination trapping, feeding stations, signs of the presence of rats and tag-trapping (i.e. live trapping, marking and retrapping in stipulated areas or grids) are, on the basis of the field data presented, discussed as methods for population studies. A method of tag-trapping has been developed for estimating the active Rattus conatus population in a population system without undue interference with the rats.
