Hopping Down the Main Street: Eastern Grey Kangaroos at Home in an Urban Matrix.

Coulson G, Cripps JK, Wilson ME - Animals (Basel) (2014)

Bottom Line: Vehicles were the major (47%) cause of mortality of tagged adults.Road-kills were concentrated (74%) in autumn and winter, and were heavily male biased: half of all tagged males died on roads compared with only 20% of tagged females.We predict that this novel and potent mortality factor will have profound, long-term impacts on the demography and behavior of the urban kangaroo population at Anglesea.

ABSTRACT
Most urban mammals are small. However, one of the largest marsupials, the Eastern Grey Kangaroo Macropus giganteus, occurs in some urban areas. In 2007, we embarked on a longitudinal study of this species in the seaside town of Anglesea in southern Victoria, Australia. We have captured and tagged 360 individuals to date, fitting each adult with a collar displaying its name. We have monitored survival, reproduction and movements by resighting, recapture and radio-tracking, augmented by citizen science reports of collared individuals. Kangaroos occurred throughout the town, but the golf course formed the nucleus of this urban population. The course supported a high density of kangaroos (2-5/ha), and approximately half of them were tagged. Total counts of kangaroos on the golf course were highest in summer, at the peak of the mating season, and lowest in winter, when many males but not females left the course. Almost all tagged adult females were sedentary, using only part of the golf course and adjacent native vegetation and residential blocks. In contrast, during the non-mating season (autumn and winter), many tagged adult males ranged widely across the town in a mix of native vegetation remnants, recreation reserves, vacant blocks, commercial properties and residential gardens. Annual fecundity of tagged females was generally high (≥70%), but survival of tagged juveniles was low (54%). We could not determine the cause of death of most juveniles. Vehicles were the major (47%) cause of mortality of tagged adults. Road-kills were concentrated (74%) in autumn and winter, and were heavily male biased: half of all tagged males died on roads compared with only 20% of tagged females. We predict that this novel and potent mortality factor will have profound, long-term impacts on the demography and behavior of the urban kangaroo population at Anglesea.

Mentions: Anglesea (38°40'S, 144°19'E) is located on the Surf Coast in southern Victoria, Australia (Figure 1). The town has about 2000 permanent human residents; the population increases at weekends and rises dramatically during summer, exceeding 10,000 at peak times [42]. Anglesea lies on the iconic Great Ocean Road, a major attraction for domestic and international tourists, and many include kangaroo viewing in their itinerary. Kangaroo imagery promotes the town: banners in the main street declare Anglesea to be ‘where bush meets sea’, the Anglesea Primary School boasts a ‘kangaroo on a surfboard’ logo, and the Anglesea Golf Club features a kangaroo on its flag and signage around the course. The town has a riverside park as well as a number of small reserves of remnant native vegetation within the urban matrix. The Surf Coast Shire, the local government authority, imposes strict regulations against clearing of vegetation on private land, and many residential blocks are well vegetated. Many blocks are unfenced and some streets are unsealed. The urban area lies within the Anglesea Heath; this forms part of the Great Otway National Park, which is an extensive, continuous reserve of native vegetation along much of the Great Ocean Road. Anglesea Heath is jointly managed by Parks Victoria and Alcoa Australia, which operates an open-cast brown coal mine and coal-fired power station in the heath north of the town [43].
