Prairie plants and animals evolved alongside free-roaming bison and the pressure of their continuous grazing. With the loss of the bison, cattle and other livestock are now filling the niche of the grazer, which is vital to the health of the prairie ecosystem. Grazing livestock maintain the variety of vegetation heights that grassland birds need, enhance the diversity of plants, and even improve carbon sequestration. Many of the remaining grasslands are owned or managed by cattle producers. In essence, this makes livestock producers the guardians of one of the world’s most endangered ecosystems, the prairie grasslands, and integral to the survival of our grassland birds!
Consider this: lands used to raise cattle represent one-third of the total agricultural land in Canada. However, they provide two-thirds of the wildlife habitat found on Canadian agricultural lands. Bobolinks, Sprague’s Pipits, Chestnut-collared Longspurs, and Burrowing Owls can thrive in pastures with cattle, bison, or even sheep. They cannot live in corn fields or lentil fields.
Being in the cattle business isn’t easy, though, and cattle producers are becoming fewer on the Canadian Prairies. In Manitoba in 2016, there were 360 fewer cattle producers than there had been just five years previous. The average age of a cattle producer in Manitoba is currently 55, and as these producers retire, there are fewer young people who want to, or are able to, take over the family ranch. The land is then often sold to the highest bidder and quite frequently tilled up and put into annual crop production. Market pressures and perverse regulatory incentives are driving the conversion of grasslands to annual crop production, and thus the loss of grassland bird habitat. It is simply more profitable to grow a field of canola or soybeans than it is to raise cattle.
