I have been involved in conservation and wildlife management and research since 2002, including extensive work with forest birds, invasive mammals and various aspects of southern ecosystems and seabirds.
Much of my recent work is seabird conservation research, both on land and at sea and I have worked with many seabird species. Robust quantification of incidental seabird mortality in commercial fisheries is a major focus, along with developing innovative mitigation techniques to reduce incidental seabird mortality.
The eradication of invasive mammals from subantarctic islands is another driving interest, especially quantifying the impacts of pest eradications on non-target species.
I have extensive experience conducting field work in extremely remote locations, both on land and at sea, for up to 13 months at a time. I plan, conduct and report on this work along with producing the associated scientific publications and management reports.
I particularly enjoy finding solutions to challenging conservation issues for governments, industry and NGOs whether it is in commercial fisheries, agri-forestry, wind-farms, private land or the conservation estate.

PROFESSIONAL POSITIONS HELD
2016 Consultant Biologist, Southern Seabird Solutions Trust
Parker Conservation is currently working on a review of mitigation measures used to prevent the incidental mortality of seabirds in New Zealand commercial fisheries. This project will assess the extent to which each mitigation measure has been developed/tested against the criteria of the international Agreement for the Conservation of Albatross and Petrels (ACAP). The aim is to allow funders and stakeholders to plan the type of support each mitigation measure may need and prioritise amongst them where needed. This project also aims to inform fishermen of the status of each of these mitigation measures.
