3 Overgrazed

4 These wholesome-looking people are the root of Desertification of the Prairie

5 Rangelands in U.S. Rangelands are vast natural landscapes in the form of grasslands, shrublands, woodlands, wetlands, and desert

6

7 Types of Grasslands/Rangelands
Temperate Grassland Prairie Tropical Savannah Pampa Steppe

8 Who Manages Rangelands?
Private Owners BLM (Bureau of Land Management) National Forest Service

10 Rangeland Management Issues
Fire Overuse Erosion Decline of Native Species

11 Fire is Good

12 Fire improves grassland habitat
Grassland after Fire Suppression Grassland when Fire is not suppressed

13 Why is Fire Good on Rangeland?
Fire is also an important regulator of range vegetation, whether set by humans or resulting from lightning. Fire tends to reduce the abundance of woody plants and promote herbaceous plants including grasses, forbs, and grass-like plants. The suppression or reduction of periodic wildfires from desert shrublands, savannas, or woodlands frequently invites the dominance of trees and shrubs to the near exclusion of grasses and forbs.[1]

21 Taylor Grazing Act

22 The Taylor Grazing Act of 1934
The Taylor Grazing Act of 1934 (43 USC 315), signed by President Roosevelt, was intended to "stop injury to the public grazing lands [excluding Alaska] by preventing overgrazing and soil deterioration; to provide for their orderly use, improvement, and development; [and] to stabilize the livestock industry dependent upon the public range“ The BLM issues/sells permits.

27 Feedlot Problems Air Pollution Water Pollution Antibiotic Resistance
Dust Nitrous Oxide (Greenhouse Gas) Methane (GHG) Smell Water Pollution Eutrophication Antibiotic Resistance Using food resources for meat production Disease promoters in the meat Mad Cow Disease Hoof and Mouth Disease

28 Mitigations and Adaptations
Keep pens wet to keep dust down Keep feedlots away from homes Build drainage systems and catch basins for wastes and waste runoff Use wastes for fertilizers on local cropland Inspect cows for disease
