We developed a generalized analytical approach to model species density in relation to environmental covariates, using the Boreal Avian Modelling Project database of point-count surveys.
Source code for the methodology is available on GitHub.

Please note, in late March 2025, we discovered a systematic error in the offsets used in these models, and have since updated the products to correct that error. For more information, please see the QPAD-offsets-correction repository or email bamp@ualberta.ca.
