Camera traps provide a novel and quasicovert method of gathering information on animal behaviour that may otherwise remain undetected without sophisticated and expensive filming equipment. In a rangelands pest management project at Mt Hope in the central west of New South Wales, Australia, we recorded foxes seemingly hunting kangaroos on three occasions. While we did not record direct instances of predation, our observations provide camera trap photographic evidence suggesting that foxes will attempt to tackle mammals above the critical weight range, including large macropod species such as western grey kangaroos.

Tree Hollow

This is the first comprehensive camera trap study to examine hollow usage by wildlife in the canopy of trees. Eighty cameras directed at tree hollows were deployed across eight sites in nine species of eucalypt in north-east New South Wales. In total, 38 species (including 21 birds, 9 mammals and 8 reptiles) were recorded at hollow entrances over a three-month period. There was a significant difference between wildlife hollow usage associated with site disturbance and tree growth stage (ANOSIM, P > 0.05); however, there was no significant difference associated with tree hollow diameter (ANOSIM, P > 0.05). The level of anthropogenic disturbance at each site, including vegetation modification of the understorey, was a significant predictor of species presence. Despite the limitations of using camera traps in the canopy of trees this study demonstrates the potential to garner useful insights into the ecology and behaviour of arboreal wildlife.

The Stability

Camera traps can detect rare and cryptic species, and may enable description of the stability of populations of threatened species. We investigated the relative performance of cameras oriented horizontally or vertically, and recording mode (still and video) to detect the vulnerable long-nosed potoroo (Potorous tridactylus) as a precursor to population monitoring. We established camera traps for periods of 13–21 days across 21 sites in Richmond Range National Park in north-east New South Wales. Each camera trap set consisted of three KeepGuard KG680V cameras directed at a bait container – one horizontal and one vertical camera in still mode and one horizontal camera in video mode. Potoroos and bandicoots (Perameles nasuta and Isoodon macrourus) were detected at 14 sites and pademelons (Thylogale stigmatica and T. thetis) were detected at 19 sites. We used program Presence to compare detection probabilities for each camera category. The detection probability for all three taxa groups was lowest for the vertical still and similar for the horizontal cameras. The detection probability (horizontal still) was highest for the potoroos (0.43) compared with the bandicoots (0.16) and pademelons (0.25). We estimate that the horizontal stills camera could achieve a 95% probability of detection of a potoroo within 6 days compared with 8 days using a vertical stills camera. This suggests that horizontal cameras in still mode have great potential for monitoring the dynamics of this potoroo population.

The Impact

We document the first evidence of tree climbing by red foxes (Vulpes vulpes) in Australia. Camera traps recorded foxes in trees on the Liverpool Plains, New South Wales. This finding prompts a reassessment of the impact that this invasive predator has on Australian fauna: from purely terrestrial to also potentially arboreal.

Daily Activity Patterns

Activity levels of spotted-tailed quolls were investigated using camera traps over 12 months. There were 33 independent camera trap photos with 17 individual quolls identified. Latency to initial detection was 40 days. Quolls were nocturnal/crepuscular, spending 35% of the day they were detected active. Highest activity levels were recorded in summer.

Exotic Pest

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.

The removal of non-toxic baits was monitored during a simulated trail-baiting programme for foxes and wild dogs in the central tablelands of New South Wales. Ninety-one buried baits were removed by a number of species including spotted-tailed quolls, Australian brush-turkeys, superb lyrebirds, small mammals, wild dogs and a red fox. Spotted-tailed quolls were significantly less likely to remove baits buried under the ground surface than baits buried in raised mounds of soil. By means of remote photography, individual quolls were identified removing 3–4 baits in one night from bait stations 400 m apart. The results of this study show that spotted-tailed quolls and other non-target species may face substantial risk of consuming baits intended for wild dogs and foxes. However, the risk of poisoning spotted-tailed quolls may be significantly reduced by appropriate planning. Recommendations are made to increase the target-specificity of baiting programmes in areas with populations of spotted-tailed quolls.

Abundance And Distribution

The distribution and abundance of ground-dwelling mammals in the major vegetation alliances in the eucalypt forests within an area of c. 24000 km2 in north-eastern New South Wales were examined. Data for 33 species of mammal from 21 areas containing 30 vegetation alliances were collected. Four notable aspects of the data were the absence or low abundance of the introduced fox (Vulpes vulpes), the widespread distribution and abundance of the cat (Felis catus), the diversity and abundance of medium-sized native mammals and the diversity of small mammals. Although differences occurred between areas and alliances, there was no significant difference in the number of native and introduced species. The ground-dwelling mammals present in the eucalypt forests of north-eastern New South Wales were more diverse and in greater abundance than those found in forests of south-eastern New South Wales. However, some species, such as the spotted-tailed quoll (Dasyurus maculatus), appear to be in urgent need of protection and management if they are to persist.

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.

Bait Stations

In Australia, baiting with 1080 (sodium fluoroacetate) is widely used to reduce predation of native wildlife by the red fox. However, such control programs may place some native carnivores at risk, particularly the spotted-tailed quoll in eastern Australia. We measured the mortality in a total of 57 quolls fitted with mortality radio-transmitters during four experimental fox baitings with Foxoff® 1080 baits containing Rhodamine B in north-east New South Wales. In all experiments quolls visited bait stations regularly and removed a total of 20 baits. All but one of these baits was found in the vicinity of the bait station, indicating that quolls did not ingest baits. This was confirmed by the absence of Rhodamine B in the vibrissae of all quolls retrapped after baiting. The only quoll that may have died from a bait had eaten a cached bait some six weeks after baiting concluded. Thus, baiting did not threaten any of the quoll populations sampled. Therefore it appears that most restrictions imposed to protect spotted-tailed quolls during fox baiting are unnecessary as long as this bait type is used.
