This occurs when there are too many animals graze for a long period of time and it will exceed the carrying capacity of the area.
4: What are ways that people are trying to preserve the grasslands on cattle ranches?

4: What are ways that people are trying to preserve the grasslands on cattle ranches?
- Paying ranchers conservation easements
- They pressure the government to zone the land preventing development of ecologically sensitive areas.
5: What were some of the causes of the American Dust Bowl of the 1930’s?
- Poor farming practices

16: What are some of the ways that National Parks are threatened?
- Locals invade the parks for resources such as wood
- They are too small to support large animal species
- Invasive species
- Buy private land inside the parks
- survey wildlife in parks
- increase the number of park rangers
- add new parkland nearby the parks
