Breeding bird studies using the mapping method were combined with intensive habitat quantification to determine the relative values to breeding avifauna of 21 habitat types. The large plot sizes allowed division of many plots into subplots, from which the value of certain habitat variations were induced. An annotated list of bird species was prepared, giving the status and phenology of all bird species observed in the study area. Suitable and preferred habitats are detailed for each bird species, as well as the population densities found in studied habitats. Potential impact of oil sands development is detailed, and recommendations as to how to minimize that impact are included. Guidelines for reclamation of developed areas are suggested.
