Report: Status and change in native forest birds
Purpose
In this report we describe patterns of status and change in 22 taxa of New Zealand’s native forest birds in two measurement periods (1969–1979 and 1999–2004) for the Parliamentary Commissioner for the Environment. This work extends a report on 64 taxa of native land birds (Walker & Monks 2017), which describes the development of a standardised national data set of bird occupancy probabilities from two national atlases of bird distribution, and summarises status and change across the native avifauna. Walker and Monks (2017) concluded that two (of six) groups of birds were in greatest need of conservation effort: endemic forest and alpine birds, and endemic wading birds, terns or gulls that breed in the inland eastern South Island. This report focuses on the 22 taxa of native forest birds found on the New Zealand mainland.
Objectives
- To investigate how scarcity of indigenous forest cover has affected native forest birds.
- To ask whether colder forests have provided native forest birds thermal refuge from predation.
- To determine how the effects of indigenous forest cover loss and temperature vary across levels of endemism and among native forest bird species.
