A comparison of three live trapping surveys to discover what Mammals live on the Tomaree Peninsula, Port Stephens, New South Wales, Australia.

This information gives some insight into population changes over time.

Michael Smith 1992


2210 trap nights

67 locations

206 mammals caught

9.4% success rate



66 Black Rat

51 Yellow-Footed antechinus

42 Brown Antechinus

11 Bush Rat

11 Swamp Rat

9 House Mouse

9 New Holland Mouse

4 Brushtail Possum

3 Northern Brown Bandicoot.


The best trapping results (70% success) were in pockets of bush that had not been burnt in memory, adjacent to houses.

The worst results (0%) were in areas burnt in the last 12 months.

Foxes were common. Feral cats were rarely seen. Echidnas seem abundant from road kills.

Kemper, C.M. 1990.


17537 trap nights

1 location

445 mammals caught

1.1 to 9.4% success rate



184 New Holland Mouse

138 House Mouse

93 Brown Antechinus

15 Black Rat

14 Swamp Rat

1 Sugar glider


Elliott "A" traps only were used in this survey. Traps were set monthly for 4 years and left out on a number of nights.

Thus the same animals were caught and re-caught to see the long term effect on population numbers. From Kemper, C.M. (1990). Small mammals and habitat disturbance -Nelson Bay and Smiths Lake. Aust. Wildl. Res 17 195-206.

Keith and Calaby 1968.


772 trap nights

10 locations

119 mammals caught

15% success rate


84 New Holland Mouse

12 Black Rat

8 Swamp Rat

7 House mouse

8 Brown Antechinus


As well 2 Ringtail possums were seen (no Brushtail possums). Some squirrel gliders and a wallaby were also seen. Feral cats were common.

It was thought that the New Holland Mouse was abundant because of the vigourous regeneration of certain plant species after fire provided ideal conditions for this seed-eating species.

"The future of the mouse in the area is insecure because its habitat is threatened by industrial and urban development", from "The New Holland Mouse in the Port Stephens District, N.S.W.", by K. Keith and J.H. Calaby C.S.I.R.O wildlife research 1968.
