Effects of energy sector development and recovery on the threatened Canada Warbler

Description: This report provides an estimate of what the total impacts of energy development are on the Canada Warbler in the Oilsands Planning Region. We show that habitat loss is occurring due to energy development with weak evidence of habitat fragmentation effects (sometimes positive, sometimes negative). This work demonstrates that the cumulative effects of oilsands and other activities are altering the size of Canada Warbler populations in the region based on changes in habitat availability but that these effects are mitigated over time as vegetation recovers.
