This study provides a transnational assessment of protected areas (PAs) and their management in North America using Saskatchewan (SK), Canada, and North Dakota (ND), USA, as contrasting subnational administrative units with common ecosystems. The study examines the historical development of grasslands from 1800 to 2000, assesses the current spatial extent and distribution of protected grasslands and identifies challenges to future grassland conservation. The assessment shows that the coverage of PAs in SK and ND is limited, that the sites are poorly distributed and concentrated in comparatively arid regions and that protected area management strategies favor multiple use over a strict focus on conservation.
