Is There A Better Way? - Overgrazing and Rangelands - Wes Davies


There is nothing wrong with asparagus, but it is not as attractive as ice cream, especially if there is no immediate competition for food. Overgrazed “ice cream” plants and under-grazed “asparagus” plants commonly occur in the same pasture under season long grazing conditions. Might I add that under-grazing can result in overgrown plants that will choke themselves to death over time, if not defoliated. A lot of money annually is pumped into restoration projects, fencing, research, and litigation because of overgrazed riparian areas that constantly get hammered by livestock doing what livestock do best; that is, eat the best grass first.

If we use our knowledge of herd animals to mimic the grazing ungulates of the past. Then livestock would be confined to herd and forced to constantly move across rangelands mimicking wild animals of the past. I am confident and the few land managers practicing this “management intensive” grazing style can attest that rangelands would improve drastically. Rather that burning overgrown forests and rangelands, which releases carbon into the atmosphere, we could manage forage in a way that gives grass plants the competitive advantage against shrubs and trees. Properly-grazed bunch grasses thrive, and can out compete other plants for resources. Since grass captures more moisture and carbon than trees and shrubs when in a thriving condition, not only would rangeland production improve but this may be the best hope we have to solving global warming.

The poster I made describes this in a visual way. Since I am a visual learner, I hope it will help some people understand these concepts better than I do.
