Concerns included the loss of Mackay’s natural heritage such as the Slade Point melaleuca forest and impacts on the reef and the islands such as the plan to subdivide Lindeman. The Mackay Conservation Group was born. Over the 30 years the group has maintained its role in advocacy for a large range of issues affecting the region, always arguing a precautionary approach to development, based on best evidence and the community’s long term best interests. The threat of increased coal mining in the region with escalating Climate Change and degradation of the reef has again been the MCGs priority this year. We had a responsibility as the peak regional group to challenge the proposed dredging and spoil dumping at Abbott Point in 2014 and the Carmichael coal mine, planned to be Australia’s largest, in the Galilee Basin this year. Our legal stand was proven right on both counts, where government agreed with us and conceded. The MCG has gained national respect for taking a stand, but became the lightning rod for anger and name calling from supporters of coal. It was a flashback to the 90s when our stand on rainforest logging and tree clearing guidelines took us to defending ourselves in the Supreme Court. The MCG has continued to contribute in multiple ways to the community over the last year – the beautiful walks, start the switch for schools, working with local groups, environmental research such as the coal dust and Eungella Honeyeater studies, educational events – with the Wood St Environment centre as the hub. Our website and newsletters offer a high quality communication to our members and the community. Over the 30 years we have been so grateful to have had dedicated and talented co-ordinators who have underpinned the MCGs activities. We were very fortunate to have had Ellen Roberts as our coordinator over the last 2 years. She has worked tirelessly and enthusiastically, with expertise and talent, much to the benefit of the MCG and the matters we stand for. She is leaving us now but will leave a lasting contribution – thank you so much Ellen. We are pleased that Peter McCallum is taking over as acting coordinator. Thanks to the management committee – it has had to make major and hard decisions again this year but I think time has demonstrated the wisdom of the committee in doing so. Thank you particularly to Christine Carlisle who has contributed so much time and energy again essential for the group. Patrician Julien, our previous coordinator, has continued to contribute tirelessly with important research and advocacy. Thank you to all our other staff and supporters helping to make this such a momentous year for the MCG. Although playing only a small role I have been proud to work with such good people and be MCGs President in 2015. 3 OUR MAJOR PARTNERS RS These organisations provide financial or in kind support for Mackay Conservation Group, or receive financial or in kind support from us, or collaborate with us on projects. Australian Youth Climate Coalition, Environment Defenders Office Queensland, Environment Defenders Office NSW, Queensland Conservation Council, Getup!, Whitsunday Residents Against Dumping, Mackay Regional Council, Australian Marine Conservation Society, Norman Wettenhall Foundation, Birdlife Mackay, Protect the Bush Alliance, 350.org, Doctors for the Environment Australia, Lock the Gate, The Australia Institute, Mackay and District Turtle Watch, Mackay Regional Council Thanks to the many people who donated to the Mackay Conservation Group. We (literally) couldn’t do it without you! REMEMBERING FELICITY WISHART S We’d like to take this opportunity to remember Felicity (‘Flic’) Wishart, who passed away in July 2015 aged 50. Felicity was a great support to Mackay Conservation Group, most recently in her role as the Great Barrier Reef Campaign Director at the Australian Marine Conservation Society. MCG actively collaborated with Flic and her team at AMCS in our shared fight to protect the Great Barrier Reef World Heritage Area from the threats of industrialisation and increased shipping. In the 2000s, Flic was a great support and mentor to MCG when she was Co-ordinator of the Queensland Conservation Council. She supported the role of small groups like ours and provided hours of her own time to support us to take up the big challenges like court cases. Flic actively advocated for the role of women in the environment movement and was a particularly active mentor to MCG staff Ellen Roberts and Gemma Plesman. Flic is pictured below presenting at an MCG event in 2013 at the MECC, and sailing on the Whitsundays with MCG staff Ellen Roberts and Moira Williams in 2014. She is greatly missed. 4 CELEBRATING THIRTY YEARS OF THE MACKAY CONSERVATION GROUP This year MCG is celebrating our 30th year protecting the region’s environmental values – a great achievement! The group started over the fight to preserve the Daintree Road in the mid eighties, a time when environmental issues had come to the fore after the success of the fight to save the Franklin Dam. Since then the activities of the MCG have been broad and diverse. Pictured left are Rod Smith and Hans Kupfer with a dugong made by Colleen Heathwood. They are about to set off from the Environment Centre on a protest calling for dugong protection zones. These zones have now been implemented up and down the Queensland coast as precious protection for a species that has declined in numbers by over 90% since 1960. In addition to preserving our unique natural heritage, Mackay Conservation Group has always encouraged people of the region to adopt more sustainable lifestyles. Former Co-ordinator Jacki Wirth is pictured here with son Bellamy in the Mackay Environment Centre with the bulk cleaning products that were available for sale. MCG also ran ‘environmental play’ sessions for children in the Environment Centre, where kids would learn about the natural environment and enjoy activities such as paper making. The Environment Centre was first opened in 1994, and had some unfriendly visitors at the opening! Throughout Queensland the ALP government was banning rainforest logging, but logging continued in the Eungella area. MCG fought to have the ban implemented here, invoking the ire of the local logging industry who parked their logging truck out the front on the day the centre opened. Barnes Creek was another focus for MCG with the fight to save the creek from the building of the East – West Connector Road. At this event, the community declared the ‘Barnes Creek National Park’ and held a cricket match on an unlevel playing field, to highlight the uneven relationship between government and corporations. President Michael Williams is pictured here addressing the crowd. MCG obviously remains very active and this an importance chance for us to reflect on where we come to and where we want to go. 5 RECOGNISING THE CONTRIBUTION OF DR MICHAEL WILLIAMS S We are proud this year to be celebrating the contribution of Dr Michael Williams who has been President of the Group since 1991, and has been very generous with his time and philanthropy. We are granting him honorary life membership. LEADING THE ORGANISATION AS PRESIDENT Michael has contributed his enormous skills and experience to the Mackay Conservation Group in the often unappreciated area of organisational governance. Michael is pictured here below outside the MCG office on Wood Street with other members of the MCG Management Committee around 1998, some four years after Centre was first opened. For 24 years Michael has supported staff and volunteers to undertake the sometimes difficult work of MCG. Michael provides guidance on important strategic and political questions but always in a collaborative way. ACTIVE IN MACKAY CONSERVATION GROUP CAMPAIGNS He has also taken a lead role in many local campaigns, such as the fight to save Barnes Creek and East Point.

Among birds, many studies have shown that tropical species have a slower pace of life than temperate-breeding species.

  • The Extent and Severity of the Mackay Highlands 2018 Wildfires and The
    THE EXTENT AND SEVERITY OF THE MACKAY HIGHLANDS 2018 WILDFIRES AND THE POTENTIAL IMPACT ON NATURAL VALUES, PARTICULARLY IN THE MESIC FORESTS OF THE EUNGELLA-CREDITON AREA HINES, H. B.1, BROOK, M.2, WILSON, J.3, McDONALD, W. J. F.4 & HARGREAVES, J.5 During an unprecedented fire season in Queensland in 2018, a complex of fires burnt in the Mackay Highlands region of Queensland. Some of these fires had been burning continuously since August, but an extreme heatwave in November caused the rapid expansion of intense fire, just prior to the wet season breaking. The fires affected 12 areas of Queensland Parks and Wildlife Service (QPWS) managed estate, with approximately 71,000 ha or 41% of this estate burnt. In this paper, we document the methods used to map the extent and severity of these fires and consider the potential impacts on natural values, within QPWS managed estate. Extensive areas (57,113 ha) of eucalypt woodlands and forests were burnt. Whilst fire adapted, the extent of fire and the high proportion burnt at very high to extreme severity in these ecosystems are likely to have affected a range of significant species. Of particular concern was the area (11,217 ha) of rainforest and scrub communities burnt, particularly cloud rainforests in the Eungella-Crediton area. These are highly fire-sensitive ecosystems and our observations suggest that, even at very low fire severity, impacts are likely highly significant and long lasting. This event provides an important opportunity to assess in detail the ecological effects of fire to inform conservation management of these fire-sensitive communities.

I have many years of experience of working with the Environmental Protection and Biodiversity Conservation Act (EPBC Act) as an employee of the Qld Department of Environment and, since retirement, as an environmental activist concerned for the protection and survival of many of the unique flora and fauna of far north Queensland. I have also served for many years on the management committee of the Environmental Defenders Office of Northern Queensland, which has given me an insight into the legal structure of the EPBC Act and how it fails to protect rare flora and fauna species. In particular I have serious concerns about: 1. the inadequacy of the listing process to protect newly discovered species that are endemic to only small areas; and 2. the weakness of the controlled action listing process due to the “significance” assessment process and the ability of people to carry out self assessments and decide that an activity is not notifiable as a controlled action. 3. the lack of implementation, or any obligation on the different levels of government to do so, for Species Recovery Plans. I will address my concerns with several case studies. 1. The Listing Process: Case Study 1: Haines Orange Mangrove (Bruguiera hainesii) In April 2016 local explorer, Hidetoshi Kudo made the remarkable discovery of Haines Orange Mangrove (Bruguiera hainesii) in mangroves adjacent to Trinity Inlet, Cairns.

    Contact Call Newsletter of BirdLife Northern Queensland Volume 9 Number 4 December 2020 Can you guess what bird this is? It’s a Pale Yellow Robin. But the images to the left are of a leucistic Pale Yellow Robin recently found at Yungaburra. What does leucistic (or leucism) mean? Leucism, or leukism, is an abnormal condition caused by a genetic mutation that prevents pigments from reaching some—or sometimes all—of a bird's feathers. The intensity of leucism varies with a bird's genetic makeup, but the skin and eyes retain their normal pigment and color. Birds with leucism can have: White coloured feathers in areas where the bird should not be white Paler overall plumage colour that looks faint, patchy or bleached Overall white plumage with little or no color visible. Leucism can be inherited. The extent and location of the paler colouration can vary between adults and their young, and can also skip generations if leucistic genes are recessive.

  • Spatial Variation in Avian Bill Size Is Associated with Humidity in Summer Among Australian Passerines Janet L
    Gardner et al. Climate Change Responses (2016) 3:11 DOI 10.1186/s40665-016-0026-z RESEARCH Open Access Spatial variation in avian bill size is associated with humidity in summer among Australian passerines Janet L. Gardner1*, Matthew R. E. Symonds2, Leo Joseph3, Karen Ikin4, John Stein4 and Loeske E. B. Kruuk1 Abstract Background: Climate imposes multiple selection pressures on animal morphology. Allen’s Rule proposes that geographic variation in the appendage size of endotherms, relative to body size, is linked to climatic variation, thereby facilitating heat exchange and body temperature regulation. Thus relatively larger appendages tend to be found in animals in warmer climates. Despite growing understanding of the role of the avian bill as an organ for heat exchange, few studies have tested the ecological significance of bill size for heat dissipation across species and environmental gradients. Amongst those that have, most have focused on the relationship with ambient temperature, but there is growing evidence that humidity also has a strong influence on heat dissipation. In particular, increasing humidity reduces the potential for evaporative cooling, favouring radiative and convective heat loss via the bill, and hence potentially favouring larger bills in humid environments. Here, we used phylogenetically-controlled analyses of the bill morphology of 36 species of Australian passerines to explore the relationship between bill size and multiple aspects of climate. Results: Humidity during the hot summer months (December-February) was positively associated with relative bill surface area across species. There was no overall association between bill size and summer temperatures per se, but the association with humidity was mediated by temperature, with a significant interaction indicating stronger associations with humidity at cooler summer temperatures.

  • Notes on the Distribution and Plumage Variation of Varied and Mangrove Honeyeaters
    Australian Field Ornithology 2019, 36, 168–172 http://dx.doi.org/10.20938/afo36168172 Notes on the distribution and plumage variation of Varied and Mangrove Honeyeaters Leo Joseph1*, Jeffrey L. Peters2, Ian J. Mason1 and Alex Drew1 1Australian National Wildlife Collection, National Research Collections Australia, CSIRO, G.P.O. Box 1700, Canberra ACT 2601, Australia 2Department of Biological Sciences, Wright State University, Dayton OH 45435, Ohio, United States of America *Corresponding author. Email: [email protected] Abstract. Considered conspecific in some recent literature, the Varied Gavicalis versicolor and Mangrove Honeyeaters G. fasciogularis have long been thought to intergrade in and around the city of Townsville, Queensland. Here we update knowledge concerning the distribution of these two species and their variation in plumage colour and pattern in the Townsville region. A lack of records between Lucinda and Townsville seems to reflect a real gap. Further work is required to clarify whether elsewhere Varied Honeyeaters may occasionally exclude Mangrove Honeyeaters in a given locality. If so, this may explain the seemingly inconsistent reports of one or the other at particular localities. Mangrove Honeyeaters immediately south of Townsville may be slightly yellower ventrally than populations further south. However, we argue that this is consistent with our genetic findings reported elsewhere and is not, we conclude, indicative of an undescribed subspecies. Introduction and ecology, he suggested that they are conspecific but advised further sampling between Cardwell in the north (where to that time only pure Varied Honeyeaters had Varied Gavicalis versicolor and Mangrove Honeyeaters been collected) and Townsville (from where he described G.
