My research since 1992 has mainly focused on population dynamics of reintroduced forest birds, targetting questions that need to be answered to improve the success of reintroduction programs. The bulk of this research has involved toutouwai (New Zealand robins), hihi (stitchbirds), and tieke (saddlebacks) on offshore islands or mainland forest fragments, and has addressed four general questions:
These questions make of four of the 10 key questions that Phil Seddon and I advocated in our 2008 paper "Directions in reintroduction biology" (see below). Examples of individual research projects are given in the selected publications below, and information on the reintroductions is given on the rundown of New Zealand reintroduction projects on the RSG Oceania web site. See http://www.hihiconservation.com/ for research related to hihi conservation.

Elizabeth Parlato, PhD student (An integrated approach for developing monitoring and management strategies for mainland reintroductions)
I currently chair the Oceania Section of the Reintroduction Specialist Group (RSG). The RSG is one of several specialist groups within the Species Survival Commission which is part of the IUCN. My role is to advise on various issues to do with reintroduction, facilitate contact between Oceania reintroduction practitioners and reintroduction practitioners overseas, and facilitate networking among reintroduction practitioners in Oceania. One initiative was creating the RSG Oceania web site, which provides extensive information on what's going on in reintroduction in Australasia, particularly in New Zealand.
I run a Postgraduate Programme in Conservation Biology which offers an MSc (coursework worth 100 points plus a thesis) and PGDipSc (coursework only). I am the coordinator and principal contributor for postgraduate papers in Conservation Biology (232.701) and Wildlife Management (232.703), coordinate the undergraduate paper in Applied Ecology and Resource Management (196.315) and also contribute to undergraduate courses in Ecology and Conservation (196.205) , Fauna of New Zealand (199.206) and Community Ecology (196.317).
