Australian islands have a vital role to play in protecting threatened species. By providing predator-free, relatively low-pressure environments, islands
can act as sanctuaries for species at risk on the mainland.
They also present novel conservation challenges and opportunities, and better information is needed on how to most effectively protect Australia’s island biodiversity.
Participants at the recent ‘Threatened Species Management on Islands: failures, successes and lessons learned’ workshop identified several areas where research can be directed to improve success rates for island conservation.
As well as looking at where and how threatened species management has been successful and unsuccessful on islands, the group discussed new and emerging challenges for island conservation and also identified potential future collaborations.
The workshop, run by Dr Justine Shaw and Associate Professor Salit Kark from the TSR Hub, attracted approximately 40 researchers from Australian, US, Scottish and Swedish universities, as well as people living and working on Lord Howe, Norfolk, Christmas and Phillip Islands.
The multi-disciplinary group included academics, research scientists, park rangers, state and federal government scientists, consultants, museum staff, community leaders and scientists from NGOs.
Management lessons from across islands and organisations were shared and will enhance future collaborations and joint projects, and the workshop will inform the future direction of the TSR Hub’s Project 4.2 (Saving species on Australian islands).
The workshop was held in conjunction with the recent Island Arks IV symposium held on Norfolk Island, in the wake of the Churchill Cyclone passing north of the island that morning.
Conservation managers considering the implementation of nest boxes programs need to give careful consideration to design, colour, placement and shade profile of nest boxes.
The vast brigalow forest that extended from northern New South Wales to southern Queensland has been cleared in the space of 60 years and it seems that many species have become threatened as a result. Rod Fensham and co-workers have identified the plant species that are likely to have become threatened and many of these species were not previously recognised as imperilled.
Monitoring is fundamental to good policy and effective conservation management. Data derived from monitoring underpin the process for listing of species as threatened, which is a precursor to recognition in policy.
TSR Hub researcher David Lindenmayer and colleagues embarked on a four-year case study examining the impacts of a biodiversity offset which established nest boxes to compensate for the losses of natural tree hollows caused by the widening of sections of the Hume Highway (the road linking Sydney and Melbourne).
In recent months you may have noticed some energetic public debate about what is the biggest threat to threatened species in Australia. Is it feral cats and foxes or is it the clearing and degradation of native vegetation?
