The Prairie Ecozone contains 5% of Canada's land area and represents 16% of the Great Plains of North America. Current estimates indicate that 25–30% of original Canadian grassland habitats remain, largely concentrated in southeastern Alberta and southwestern Saskatchewan with fragments distributed throughout southern Manitoba. The size, distribution and condition of native grasslands serve as valuable indicators of the ecological integrity and the sustainability of those landscape types. With… 

Distribution of priority grassland bird habitats in the Prairie Pothole Region of Canada

TLDR
This work uses data from the North American Breeding Bird Survey to develop species distribution models for 15 grassland bird species across the Prairie Pothole Region of Canada and generates multispecies habitat priority maps.

Ecoregions of Canada's prairie grasslands

The Central Plains of Western Canada comprise the Prairies Ecozone and the Boreal Plains Ecozone. The former has the most grasslands and is divided into seven ecoregions: Mixed Grassland, Cypress

The Influence of Land Use and Fences on Habitat Effectiveness, Movements and Distribution of Pronghorn in the Grasslands of North America

The pronghorn Antilocapra americana is a grassland and shrub-steppe obligate unique to North America. The species was driven to low abundance during agricultural settlement in the West. Extensive

Southern Canada’s crisis ecoregions: identifying the most significant and threatened places for biodiversity conservation

Identifying and protecting key areas for biodiversity is a cornerstone of effective nature conservation. This conservation assessment analyzes 77 ecoregions across the southern, settled part of

Grassland conservation in North Dakota and Saskatchewan: contrasts and similarities in protected areas and their management

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

Monitoring an ecosystem at risk: What is the degree of grassland fragmentation in the Canadian Prairies?

TLDR
The meff method is supported in this study as highly suitable and recommended for long-term monitoring of grasslands in the Canadian Prairies; it can help set measurable targets and/or limits for regions to guide management efforts and as a tool for performance review of protection efforts.

Conservation of Grassland Birds in North America: Understanding Ecological Processes in Different Regions: "Report of the AOU Committee on Conservation"

TLDR
The habitat requirements of birds in six types of grassland in six regions of North America were examined, finding heavy grazing by prairiedogs or bison created a low “grazing lawn” that is the preferred habitat for many grassland bird species that are restricted to the shortgrass prairie and desert grasslands.

Agricultural destruction of Northern Pintail nests on cropland in prairie Canada

TLDR
Using spatial modeling at multiple scales, it is estimated that the long-term average breeding population of Northern Pintails in prairie Canada would have initiated a mean of 974,260 nests/year, of which 47% would have been in cropland, and provides additional support for the theory that the pintail’s habit of nesting in Cropland is the probable reason for the decline in the pintails population, irrespective of the cause of nest loss.

Native bee communities vary across three prairie ecoregions due to land use, climate, sampling method and bee life history traits

Recent evidence indicates that many native bee species are in decline due to the cumulative effects of multiple human‐induced stressors such as habitat loss, pesticide exposure, pathogens, and
