In 2022, scientists from Parks Canada, Audubon, the Canadian Wildlife Service and Birds Canada published an analysis of projected changes in bird assemblages due to climate
change within the Canadian National Park System (Gahbauer et al. 2022, Projected changes in birds assemblages due to climate change in a Canadian system of protected areas; https://doi.org/10.1371/journal.pone.0262116). This brief summarizes projected changes in climate and vegetation biome suitability by mid-century for 434 native bird species across 49 national parks, national marine conversation areas, and a national urban park in Canada under IPCC’s high emissions trajectory (RCP8.5) to mid-century (2050s), representing a 2°C mean rise in temperatures worldwide.
