Published in: Ecological Modelling Authors: Doug P. Armstrong, Elizabeth, H. Parlato & Peter G.H. Frost Abstract: Survival, reproduction and detection rates may vary greatly amongst individuals. Failure to account for this variation results in biased inferences about age effects and population size. However, individual variation is not normally considered in population viability analysis, potentially leading […]
The number of female hihi at Whanganui’s Bushy Park Tarapuruhi sanctuary has doubled after a better breeding season. Hihi, or stitchbirds, were once common but are now one of New Zealand’s most endangered birds. Read the full story from the New Zealand Herald here
We are very happy to share that Caitlin has submitted her PHD. This is a truly global PHD effort with a focus on hihi dietary variation. It included field study on multiple hihi populations (Tiritiri Matangi, Rotokare, Bushy Park Tarapuruhi and Zealandia) and even some sites where we hope to see hihi in the future […]
Published in: Conservation Science and Practice Authors: Julia Panfylova, John G Ewen and Doug Armstrong Abstract: Structured decisionâ€making (SDM) has become popular in natural resource management but has been underused in reintroduction programs. We illustrate how conservation managers can use SDM to guide management decisions after initial reintroduction, when data are still limited and uncertainty […]

Published in:Â The Journal of Wildlife Management Date published:Â May 2016 Authors:Â Julia Panfylova, Ellis Bemelmans, Chris Devine, Peter Frost, Doug Armstrong Abstract Modeling survival of reintroduced populations is critical for understanding population dynamics and therefore making appropriate management decisions. We analyzed survival data collected over the first 2 years after a reintroduction of hihi (Notiomystis cincta), an […]
