Population Status & Trend
Reliable and accurate estimation of species’ population size, trend and distribution is important for informing status assessment, conservation planning and Species at Risk recovery actions. BAM is committed to developing approaches to estimate the density, distribution, and trends of boreal birds using heterogeneous datasets. In recent years, we have made significant progress developing a new national modelling approach. We currently offer a new set of national-scale data products including density maps and population estimates for 143 landbird and 18 waterfowl species. We will continue to collaborate with partners to further refine our methods and expand the scope of our products.
