The Boreal Avian Modelling Project has collated extensive avian and biophysical databases. The team has developed and applied various methods to address issues related to:
- adjusting avian point count data to account for detection biases
- estimating density and population
- predicting distribution and relative habitat suitability
- standardising biophysical data
- characterising forest conditions
This section explains the methods used to derive the results that are included by individual boreal species in the RESULTS section.
These analytical techniques form the basis for more detailed predictive modelling. Spatial models of avian abundance, distribution, habitat associations, and community structure are being built and validated using BAM's avian and biophysical data, and the methods described here. Among their many applications, these spatial models will be used to evaluate whether different scenarios of land use or climate change are likely to sustain boreal bird populations, communities, and habitats. They will also help to identify species that might function as key indicators of habitat condition.
