Warren destruction by ripping reduced the number of warrens on a property in western New South Wales to a very low level. After the cessation of ripping the number of warrens remained low for three years. In the following years rainfall was above average and during this period the number of warrens increased considerably.

The diet of feral cats (Felis catus) was studied at Lake Burrendong, central-eastern New South Wales, from July 1994 to June 1997. Mammals were the major prey in 499 scats that were analysed. Rabbits (Oryctolagus cuniculus) were the staple prey, while carrion was an important secondary food. Invertebrates, other mammalian prey, vegetation, birds and reptiles were generally minor components of the diet. Few significant seasonal differences in diet were found; however, invertebrates contributed less and possums more to the diet in winter and summer respectively. A significant dietary response was found to changes in rabbit abundance, but not for the other prey types. Cats continued to prey heavily on rabbits even after a 90% decline in rabbit abundance occurred, which coincided with the advent of Rabbit Calicivirus Disease (RCD). House mice (Mus domesticus) increased in importance in the diet ten months post-RCD. Although the abundance of cats was correlated with the abundance of some prey species, other factors may have influenced the observed patterns; these are discussed.

Populations of non-target birds and mammals on a semi-cleared grazing property near Braidwood, New South Wales, did not appear to be affected by a trail-baiting campaign against rabbits, Oryctolagus cuniculus, using pellet bait and 1080 poison. Rabbit numbers were reduced by about 90% and those of the fox, Vulpes vulpes, another exotic pest, by about 75%. Populations of both pest species began recovering soon after the campaign, indicating the need for continued control measures.

Autumn And Winter

The diets of 212 foxes (Vulpes vulpes) in the far south-west of New South Wales were determined between 1985 and 1989 and compared with other Australian studies. Mammalian remains, at an overall occurrence of 99.1%, formed the basis of the diet during the autumn and winter months. The most frequently occurring mammals were rabbits (Oryctolagus cuniculus) (34.9%), sheep (Ovis aries) (30.7%) and macropods (Macropus spp.) (20.3%). Insects occurred in 31.1% of stomachs and formed a substantial proportion of the diet. Fresh newborn lamb was identified in only 3.8% of all stomachs, but evidence of lamb consumption was 10 times greater (35.2%) from foxes collected near lambing flocks. Other studies around lambing flocks have also shown a high occurrence of fresh lamb in fox stomachs and there is circumstantial evidence that predation of lambs by foxes can be common. It was concluded that lamb predation is likely to be severe where the fox population density is high, where older foxes predominate, and where alternative preferred foods are scarce. More research is required to confirm these observations.

The effectiveness of warren ripping as a method for controlling rabbits in a semi-arid environment was tested on a 3000 ha site at Kinchega National Park in western New South Wales. Estimates of rabbit numbers made during the study showed that the immediate effect of warren ripping was to reduce the rabbit population by about 65%. The longer term effect was to stabilise numbers at a relatively low level. The only warrens active 14 months after being ripped were those which gained new burrow entrances within two months of being destroyed. Re-opening rate of warrens was greatest for large limestone warrens where 90% of ripped warrens were again active after two months. Less than 30% of all sandy warrens became active again. Within each re-opened warren, the number of active entrances increased slowly but 14 months after being destroyed they had still not reached their original size.

In the winters of 1969 and 1970 a total of 64 rabbits was shot at 11 sites covering diverse climatic regions in the western, central and eastern districts of New South Wales. The ectoparasites of these rabbits were identified and counted. The flea Echidnophaga myrmecobii was most frequently found in western districts; the louse Haemadipsus ventricosus was prevalent in the central districts; the mite Listrophorus gibbus was very abundant on rabbits from the eastern districts, whilst the mite Cheyletiella parasitivorax was prevalent on rabbits from central and eastern districts.The probable consequences of these variations are discussed in relation to their possible effects on the epidemiology of myxomatosis.This investigation was carried out as part of the study of the biology of the wild rabbit undertaken by the Division of Wildlife Research, CSIRO, under the general supervision of Mr K. Myers. The author is indebted to P. Haycock and Miss S. Stephens for invaluable technical assistance. Messrs I. Parer, M. Stranger, G. Richards, H. Bults, J. Libke and P. Haycock shot the rabbit samples.

Contrary to previous literature, P. xanthopus had not been recorded in western New South Wales before its existence was reported by Fox (1966). There is only one geographically isolated population of less than 250 animals in two separate colonies in the Gap and Coturaundee Ranges, where they are confined to two cliff systems and two outcrops. Their distribution is therefore more limited than first reported by Wilson et al. (1976). They were more widespread in the past, being found also in the Barrier and Bynguano Ranges. These conclusions have been reached from data collected from: (1) a large-scale low-level aerial survey and subsequent ground inspections to record this species' presence in specific locations in north-western New South Wales; (2) a systematic detailed survey of the Gap and Coturaundee Ranges to establish its pattern of habitat use from the accumulated density of faecal pellets; (3) low-level aerial surveys over these and other areas, by helicopter, to confirm the results of earlier surveys and check on reported sightings. The results of this study are being used for the management of this rare rock-wallaby in New South Wales. It is recommend that this species be re-established in the Bynguano Range.

Rabbit warrens in a semiarid environment of New South Wales were concentrated in those areas where impact penetrometer readings indicated friable soil to a depth of at least 75 cm. Isolated warrens in areas with few warrens were found in restricted patches of favourable soil. The absence of warrens from areas with shallow soil was considered to be due to high soil temperatures. The distribution of the rabbit in Australia was examined in relation to deep soil temperatures. It was suggested that the application of bituminous coating on ripped warrens may be a useful technique for the control of rabbits in the arid zone.
