The Code is implemented through education and relevant government authority legislation as appropriate. The Code replaces the (National) Code of Practice for the Humane Shooting of Kangaroos which was developed by Australian, state and territory government authorities and endorsed by the former Council of Nature Conservation Ministers (CONCOM) in 1985. The 1985 edition was revised and the second edition was endorsed by CONCOM and published in 1990. Since 1990, there has been a considerable amount of scientific research conducted into kangaroo behaviour and ecology and considerable changes in the kangaroo industry. A review of the 1990 Code allowed the determination of the minimum achievable standard of humane conduct under present circumstances. In 2002, the Natural Resource Management Ministerial Council (NRMMC) established a working group to review the Code. The NRMMC consists of the Australian, state, territory and New Zealand government ministers responsible for primary industries, natural resources, environment and water policy. The Working Group included representatives from Australian, State and Territory government authorities responsible for kangaroo management and welfare, the kangaroo industry, RSPCA and Animals Australia. The Working Group sought public comment on the revision of the Code and these comments were taken into account in the development of two separate codes, a commercial and a non-commercial code. This first edition of the non-commercial code was endorsed by NRMMC on the 7th of November 2008 and should be read in conjunction with the National Code of Practice for the Humane Shooting of Kangaroos and Wallabies for Commercial Purposes. National code of Practice for the Humane Shooting of Kangaroos and Wallabies for Non-Commercial Purposes 4 1. INTRODUCTION 1.1 Purpose of the Code This Code has been produced to ensure that all persons intending to shoot free-living kangaroos or wallabies for non-commercial purposes undertake the shooting so that the animal is killed in a way that minimises pain and suffering. 1.2 Definitions In this Code, the terms ‘kangaroo’ and ‘wallaby’ mean all species of the family Macropodidae within the superfamily Macropodoidea which includes kangaroos, wallaroos (or euros), wallabies and pademelons. For the purposes of this Code, a non-commercial purpose is where the animal shot is not used as product to be sold within Australia or overseas. 1.3 Legislation All shooting of kangaroos and wallabies, whether on public or private land, is subject to law. As the laws may differ between states and territories, shooters must contact the relevant government authority in the state or territory in which the shooting will occur for appropriate advice. Except where specifically exempted by law, states and territories will require the shooter to have a licence or permit issued by a relevant government authority. The licence or permit will specify any conditions or restrictions that may apply. The requirements of this Code do not override state or territory animal welfare legislation. A lack of knowledge of relevant state or territory animal welfare legislation is no defence against prosecution for animal welfare offences. National code of Practice for the Humane Shooting of Kangaroos and Wallabies for Non-Commercial Purposes 5 1.4 Structure of the Code The Code is divided into six sections covering: • Introduction • Technical specifications and procedures • Shooting for non-commercial purposes • Euthanasing injured kangaroos and wallabies • Euthanasing pouch young and young at foot and • Shooting for scientific purposes, and • Shooting for special purposes The Code also has three Schedules. These are: Schedule 1: Minimum specifications for firearms and ammunition Schedule 2: Points of aim for a shot to the brain and Schedule 3: Points of aim for a shot to the heart. In each section an introduction provides background to the conditions that must be adhered to by all persons shooting kangaroos and wallabies. 2. TECHNICAL SPECIFICATIONS AND PROCEDURES The range of firearms and ammunition available to licensed shooters in Australia is extensive, but only a small selection

  • Red-Necked Wallaby (Bennett’S Wallaby) Macropus Rufogriseus
    Red-necked Wallaby (Bennett’s Wallaby) Macropus rufogriseus Class: Mammalia Order: Diprotodontia Family: Macropodidae Characteristics: Red-necked wallabies get their name from the red fur on the back of their neck. They are also differentiated from other wallabies by the white cheek patches and larger size compared to other wallaby species (Bioweb). The red-necked wallaby’s body fur is grey to reddish in color with a white or pale grey belly. Their muzzle, paws and toes are black (Australia Zoo). Wallabies look like smaller kangaroos with their large hindquarters, short forelimbs, and long, muscular tails. The average size of this species is 27-32 inches in the body with a tail length of 20-28 inches. The females weigh about 25 pounds while the males weigh significantly more at 40 pounds. The females differ from the males of the species in that they have a forward opening pouch (Sacramento Zoo). Range & Habitat: Flat, high-ground eucalyptus Behavior: Red-necked wallabies are most active at dawn and dusk to avoid forests near open grassy areas in the mid-day heat. In the heat, they will lick their hands and forearms to Tasmania and South-eastern promote heat loss. (Animal Diversity) These wallabies are generally solitary Australia. but do forage in small groups. The males will have boxing matches with one another to determine social hierarchy within populations. They can often be seen punching, wrestling, skipping, dancing, standing upright, grabbing, sparring, pawing, and kicking. All members of the kangaroo and wallaby family travel by hopping. Red-necked wallabies can hop up to 6 feet in the air.

A number of stud- ies have demonstrated that red foxes (Vulpes vulpes) have a profound effect on the population biol- ogy of some species. However, not all species exposed to fox predation have declined. We studied the antipredator behaviour of a species that has not declined – the red-necked pademelon (Thylogale thetis), and contrasted it with previous studies on a species that has declined – the tammar wallaby (Macropus eugenii), to try to understand behavioural factors associated with survival. We focused on two antipredator behaviours: predator recognition and the way in which antipredator vigilance is influ- enced by the presence of conspecifics. We found that predator-naïve pademelons responded to the sight of certain predators, suggesting that they had some degree of innate recognition ability.

  • Energetics and Biomechanics of Locomotion by Red Kangaroos (Macropus Rufus)
    Comparative Biochemistry and Physiology Part B 120 (1998) 41–49 Review Energetics and biomechanics of locomotion by red kangaroos (Macropus rufus) Rodger Kram a,*, Terence J. Dawson b a Department of Integrati6e Biology, Uni6ersity of California, Berkeley CA 94720-3140, USA b School of Biological Sciences, Uni6ersity of New South Wales, Sydney NSW 2052, Australia Received 15 May 1997; received in revised form 22 September 1997; accepted 7 October 1997 Abstract As red kangaroos hop faster over level ground, their rate of oxygen consumption (indicating metabolic energy consumption) remains nearly the same. This phenomenon has been attributed to exceptional elastic energy storage and recovery via long compliant tendons in the legs. Alternatively, red kangaroos may have exceptionally efficient muscles. To estimate efficiency, we measured the metabolic cost of uphill hopping, where muscle fibers must perform mechanical work against gravity. We found that −1 uphill hopping was much more expensive than level hopping. The maximal rate of oxygen consumption measured (3 ml O2 kg s−1) exceeds all but a few vertebrate species. However, efficiency values were normal, 30%. At faster level hopping speeds the effective mechanical advantage of the extensor muscles of the ankle joint remained the same. Thus, kangaroos generate the same muscular force at all speeds but do so more rapidly at faster hopping speeds. This contradicts a recent hypothesis for what sets the cost of locomotion. The cost of transport (J kg−1 m−1) decreases at faster hopping speeds, yet red kangaroos prefer to use relatively slow speeds that avoid high levels of tendon stress. © 1998 Elsevier Science Inc.

  • Feratox® As a Humane Control Agent for Wallabies in Tasmania
    Feratox® as a Humane Control Agent for Wallabies in Tasmania Mick Statham Tasmanian Institute of Agricultural Research, University of Tasmania, Launceston, Tasmania, and Mt. Pleasant Labs, Kings Meadows, Tasmania, Australia Charles T. Eason Dept. of Ecology, Lincoln University, Lincoln, and Connovation Research Ltd., Auckland, New Zealand Helen L. Statham Tasmanian Institute of Agricultural Research, University of Tasmania, Launceston, Tasmania, Australia Lee Shapiro and Duncan MacMorran Connovation Research Ltd., Auckland, New Zealand ABSTRACT: Compound 1080 has been used to control native wallabies and possums in Tasmania for over 50 years. Public concern in relation to humaneness and its effects on domestic dogs and nontarget species has led to opposition to its use. Feratox®, a form of encapsulated cyanide pellet registered for brushtail possum control in New Zealand, was considered as a replacement toxin. Trials in New Zealand showed that the material is fast-acting and humane in wallabies. In Tasmania, protocols were developed using bait stations that would minimise access by nontarget macropods and wombats. In field trials using Feratox®, however, there was excessive spillage of toxic pellets and variation in bait take between seasons by Tasmanian pademelons. Further work is under way to resolve these issues to see if protocols can be developed for the safe and effective use of cyanide pellets in areas where nontarget mammals are prevalent.

  • Dama Wallaby Sustainable Macropus Eugenii Options Pest Animal Control 16
    Dama wallaby Sustainable Macropus eugenii Options Pest Animal Control 16 Dama wallaby are also known as; Tammar, silver-grey or Kangaroo Island wallaby. Description One of the smallest wallaby species, dama wallaby stand up to half a metre tall. Adult females weigh around 5 kilograms, while males can weigh up to 7 kilograms. They are grey-brown in colour with a paler grey underbelly. A thin white-silver stripe runs from under the eye to the nose. Mature animals may have a patch of reddish brown colouring at the shoulder. 30 mm Field sign Dama wallaby prints in soft mud Wallaby droppings In areas of sand or soft soil, the long narrow hind feet and tail of wallaby leave a characteristic track. The footprint of a wallaby is a two-pronged print with a large central toe extending further than the outer toe. Their faecal pellets are also comparatively distinctive, slightly larger than an individual deer pellet and often a tear-drop shape. Origin Formerly widespread in southern mainland Australia, dama wallaby are now restricted to south-western Western Australia and southern South Australia. Wallaby were first introduced to New Zealand around 1870 by Sir George Grey, when they were released onto Kawau Island. Dama wallaby, sourced from Kawau Island, were subsequently liberated near Lake Ōkāreka in 1912. Where are they found? Dama wallaby have become established in both exotic and native forest or scrub. Since 1912, they have spread west to Rotorua, east to Kawerau and south to about Rainbow Mountain; an area of approximately 200,000 ha. To the right is a map of the known distribution of wallabies, as at January 2012.

  • Post-Release Monitoring of Western Grey Kangaroos (Macropus Fuliginosus) Relocated from an Urban Development Site
    animals Article Post-Release Monitoring of Western Grey Kangaroos (Macropus fuliginosus) Relocated from an Urban Development Site Mark Cowan 1,* , Mark Blythman 1, John Angus 1 and Lesley Gibson 2 1 Biodiversity and Conservation Science, Department of Biodiversity, Conservation and Attractions, Wildlife Research Centre, Woodvale, WA 6026, Australia; [email protected] (M.B.); [email protected] (J.A.) 2 Biodiversity and Conservation Science, Department of Biodiversity, Conservation and Attractions, Kensington, WA 6151, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-8-9405-5141 Received: 31 August 2020; Accepted: 5 October 2020; Published: 19 October 2020 Simple Summary: As a result of urban development, 122 western grey kangaroos (Macropus fuliginosus) were relocated from the outskirts of Perth, Western Australia, to a nearby forest. Tracking collars were fitted to 67 of the kangaroos to monitor survival rates and movement patterns over 12 months. Spotlighting and camera traps were used as a secondary monitoring technique particularly for those kangaroos without collars. The survival rate of kangaroos was poor, with an estimated 80% dying within the first month following relocation and only six collared kangaroos surviving for up to 12 months. This result implicates stress associated with the capture, handling, and transport of animals as the likely cause. The unexpected rapid rate of mortality emphasises the importance of minimising stress when undertaking animal relocations. Abstract: The expansion of urban areas and associated clearing of habitat can have severe consequences for native wildlife. One option for managing wildlife in these situations is to relocate them.

  • Biparental Care and Obligate Monogamy in the Rock-Haunting Possum, Petropseudes Dahli, from Tropical Australia
    ANIMAL BEHAVIOUR, 2000, 59, 1001–1008 doi:10.1006/anbe.1999.1392, available online at http://www.idealibrary.com on Biparental care and obligate monogamy in the rock-haunting possum, Petropseudes dahli, from tropical Australia MYFANWY J. RUNCIE CRC for Sustainable Development of Tropical Savannas, Northern Territory University (Received 10 May 1999; initial acceptance 9 June 1999; final acceptance 30 December 1999; MS. number: 6222R) Monogamy is rare among mammals, including marsupials. I studied the social organization of the little-known rock-haunting possum in Kakadu National Park in Northern Australia. Preliminary field observations revealed that the majority of possums live in cohesive groups consisting of a female–male pair and young, suggesting a monogamous mating system. I used radiotracking to determine home range patterns, and observations to measure the degree of symmetry between the sexes in maintaining the pair bond and initiating changes in group activity. I also measured the extent of maternal and paternal indirect and direct care. Nocturnal observations and radiotelemetric data from 3 years showed that six possum groups maintained nonoverlapping home ranges with long-term consorts and young sharing dens. Males contributed more than females to maintaining the pair bond but they contributed equally to parental care. For the first time, the parental behaviours of bridge formation, embracing, marshalling of young, sentinel behaviour and tail beating are reported in a marsupial. Males participated to a high degree in maintaining relationships with one mate and their offspring. Collectively, these results suggest that the mating system of this wild population of rock-haunting possums is obligate social monogamy.

    Species Status Assessment Report for the Giant Kangaroo Rat (Dipodomys ingens) Photo by Elizabeth Bainbridge Version 1.0 August 2020 Prepared by the U.S. Fish and Wildlife Service August 2020 GKR SSA Report – August 2020 EXECUTIVE SUMMARY The U.S. Fish and Wildlife Service listed the giant kangaroo rat (Dipodomys ingens) as endangered under the Endangered Species Act in 1987 due to the threats of habitat loss and widespread rodenticide use (Service 1987, entire). The giant kangaroo rat is the largest species in the genus that contains all kangaroo rats. The giant kangaroo rat is found only in south-central California, on the western slopes of the San Joaquin Valley, the Carrizo and Elkhorn Plains, and the Cuyama Valley. The preferred habitat of the giant kangaroo rat is native, sloping annual grasslands with sparse vegetation (Grinnell, 1932; Williams, 1980). This report summarizes the results of a species status assessment (SSA) that the U. S. Fish and Wildlife Service (Service) completed for the giant kangaroo rat. To assess the species’ viability, we used the three conservation biology principles of resiliency, redundancy, and representation (together, the 3Rs). These principles rely on assessing the species at an individual, population, and species level to determine whether the species can persist into the future and avoid extinction by having multiple resilient populations distributed widely across its range. Giant kangaroo rats remain in fragmented habitat patches throughout their historical range. However, some areas where giant kangaroo rats once existed have not had documented occurrences for 30 years or more. The giant kangaroo rat is found in six geographic areas (units), representing the northern, middle, and southern portions of the range.

  • Ba3444 MAMMAL BOOKLET FINAL.Indd
    Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.
