Land

2. Land Use in the U.S.
Rural Land: land with relatively few people and open area
Forests
Parks and preserves
Cropland
Rangeland and pastures
other
Urban land: area that contains 2,500 people and has a governing body.

3. Types of Rural Land Rangeland Forest land Cropland Parks and Preserves
Graze livestock and wildlife
Forest land
Harvesting wood
Fish
Wildlife
Cropland
Grow food
Parks and Preserves
Recreation
Aesthetic purposes
Preserve native plants and animals
Wetlands, mountains, deserts, etc
Land that is difficult to use for human purposes

4. Global Population Trends

5. Why are people dependent on rural land, no matter where they live?
Ecosystem services: services that are provided from natural environments that can have a monetary value associated with them
Wood
Food
Water filtration
Shelter
Climate
Flood control

6. If we rely on rural services then why do we live in urban areas?
Green revolution
Higher yields for same area.
Less man power needed
Industrialization
Movement into cities

7. Positives to Moving to urban areas
Better jobs
Resources in smaller area
Transportation
More jobs

8. Negative impacts
Urbanization: Rapid movement into cities which puts stress on infrastructure
Infrastructure: all buildings, bridges, roads, schools, medical care, electricity, water etc. that a urban are uses.
Urban sprawl- rapid expansion from urban area into the surrounding suburban area
Heat island- increased temperature due to infrastructure
Suburban sprawl- further movement into suburban areas.

9. Land Use Management:
Land use planning- the advanced determination of how land will be used for homes, business, factories, and recreation.

10. Farmland aka Cropland
20% of US land that is used to grow crops and fruit.
250 million acres
1996 National Farmland Protection Program
Strives to prevent Urban sprawl from taking over farmland

11. Rangeland
28% of U.S. land which is used to support vegetation found in grasslands, forests, deserts, but is not used for farming or timber.
Soils tend to be infertile
Mostly used for grazing animals such as cattle, sheep, goats.
Important for the world’s meat supply.

12. Problems on the Range
Overgrazing- allowing more animals to graze on an area than that area is capable of supporting.
Tragedy of commons idea
Leads to degradation and soil erosion

13. PUBLIC RANGELANDS IMPROVEMENT ACT OF 1978
Limits heard size
Create recovery periods when no herds allowed
Kill invasive plants and plant native
Increase grazing locations via water-hole creation.

14. Forest Land - forest that is planted and managed
28% of land ~1,800cm3 of wood used per person per day in world
US uses 3.5 x as much as dvping countries
Dvping countries use wood as main source of fuel.
3 types of forest
Virgin forest
- forest that has never been cut
Native forest
- forest that is planted and managed
Tree Farms
- trees that are planted in rows and harvested like crops

15. Parks and Preserves
391 Federal Parks and Preserves in the United States
Protect natural or historic areas
Increase biodiversity
Research
Wilderness
Wilderness Act of land that is protected from all types of development and exploitation.
