Geographic region in southern Alberta and Saskatchewan

Palliser's Triangle , or the Palliser Triangle, is a semi arid steppe occupying a substantial portion of the Western Canadian Canadian Prairies, Saskatchewan, Alberta and Manitoba, within the Great Plains region. While initially determined to be unsuitable for crops outside of the fertile belt due to arid conditions and dry climate, expansionists questioned this assessment, leading to homesteading in the Triangle. Agriculture in the region has since suffered from frequent droughts and other such hindrances.

This area was and is still very productive in terms of both produce and livestock. Alberta and Saskatchewan are currently the provinces with the second and third most farms, respectively, only being surpassed in this respect by much more populous Ontario. This is despite the fact that Palliser's Triangle, which occupies much of the southern portions of both of these provinces, has had consistent issues with droughts, almost every decade being marked by at least one dry year, in no small part due to the orographic lift caused by the Rockies, the Coast Mountains, the Cascade Range and the Sierra Nevada Range. This has much to do with efforts to maintain sustained agricultural practices such as crop diversification and conservation tillage which have softened the blow of complications that could have otherwise had far more severe effects. The reverse is true in Alberta, which has the second largest total farmland and the highest number of cattle. This Western Canadian agriculture is noticeably focused in the Palliser's Triangle region, demonstrating that agriculture in the area has persisted in spite of the dry climate. Despite the frequent and sometimes disastrous droughts, the Triangle did become and still is the metaphorical breadbasket of the nation as he expected. However, the region has also suffered a major loss in terms of biodiversity over the course of settlement. Canada as a whole has found itself with under 20% of its mixed grass prairies, under 5% of its fescue prairies, and less than a half percent of its tall grass prairies. In addition, the prairies have a very high rate of endangered species.
