Where is pallisers triangle

The boundary of the Palliser Triangle is not fixed like a political boundary. Rather it fluctuates depending on climatic cycle, or the purpose of the person mentioning the region. Today boundaries of physio-graphic regions such as the brown soil zone or the mixed grassland prairie ecoregion are often used to indicate the Palliser Triangle see Figure PT Characterized by its aridity, the mixed grassland ecoregion has an annual water deficit the amount that the potential evapotranspiration exceeds the precipitation of mm.

It is a natural grassland with few native trees or wetlands. Its landscape is diverse, from level, glacial lake plains to the rolling Missouri Coteau.

Leaving crop residue on fields over winter traps snow, increasing soil moisture and offering protection from wind and water erosion. Crop diversification offers the possibility of profit from one product when another fails. Mother Nature definitely holds the upper hand in Palliser's Triangle, but adapting to the environment and learning from experience has ensured that Macoun's prediction of a successful wheat-growing region would come true-with or without drought.

The Palliser's Triangle is a mixed grassland ecoregion, and it possesses a yearly annual water deficit of mm. It has few wetlands and also few indigenous tree species. The region's landscape ranges from the rolling Missouri Coteau, glacial lake plains, to level ground. The town of Leader, which is situated in the region, records a yearly precipitation of mm, while the yearly snowfall is cm. For many years the region was attractive to ranchers.

The wettest period of the year occurred during late spring and early summer, and it was the time when plants most required precipitation. Cattle grazing was further sustained by dry weather, sandy soil, and grassy land cover.

Multiple ranchers in the United States drove their herds north for them to graze in the triangle. By , most of the land had been overgrazed. For a period yields were fruitful, but inefficient agricultural practices coupled with dry conditions made the area a Dust Bowl in the s and contributed to the Great Depression in Canada.
