Research
Programme
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:
- What habitat conditions are needed for
persistence
of the reintroduced population?
- To what extent will inbreeding depression affect persistence of
the
reintroduced
population?
- How heavily should source populations be harvested?
- Should translocation be used to compensate for isolation in
fragmented
landscapes?
These questions make of four of the 10 key questions that Phil Seddon
and
I have recently advocated in a paper on "Directions in reintroduction
biology"
in Trends in Ecology and evolution (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 my reintroduction
web site. See http://www.hihiconservation.com/
for iresearch related to hihi conservation.

Role
in Reintroduction Specialist Group
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 practioners overseas,
and
facilitate networking among reintroduction practitioners in Oceania.
My main initiative has been to create a reintroduction
web site, which provides extensive information on what's going on
in
reintroduction in Australasia, particularly in New Zealand.

Teaching
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). Click HERE
