Precision Analysis of Bird Trend Monitoring in NWT Proposed National Wildlife Areas

The objective of this work was to predict how precise trend estimates would be for songbirds monitored in four proposed National Wildlife Areas (NWA) in the Northwest Territories, with different possible sampling intensities and durations of sampling. The information is intended to provide guidance for design of the bird monitoring program in each area, and to set expectations about how long it will take to obtain trend estimates at particular precision levels for different species.
