Summary of Land Resources and Management
U.S. National Parks
- Pinnacles National Park, CA: Habitat for the California condor, established 2013, previously a national monument since 1908.
Land Use in the United States
- Ownership: 60% private citizens; 28% federal; 9% state/local government; 2% Native American tribes.

- U.S. Department of the Interior: Bureau of Land Management (BLM), Fish and Wildlife Service (FWS), National Park Service (NPS).
- U.S. Department of Agriculture: U.S. Forest Service (USFS).
Ecosystem Services
- Federal lands provide critical ecosystem services: wildlife habitat, flood control, groundwater recharge, recreation opportunities.
Forests and Ecosystem Functions
- Forests cover 1/4 of Earth's land, provide timber, habitat, and ecosystem services (e.g., carbon sinks, climate regulation).
- Forest Management Methods: Ecologically sustainable practices versus monoculture plantations.
Deforestation
- Major issue; 230 million hectares lost globally (1990-2015).
- Most significant in tropical forests; causes soil erosion, loss of biodiversity, and contributes to climate change.
Rangelands
- Primarily for grazing, support livestock, and vegetation growth crucial for soil stability.
- Overgrazing leads to land degradation and desertification.
National Parks and Wilderness Areas
- The National Park Service administers parks; focuses on education and resource management.
- Wilderness Areas: Strictly preserved land, limited human activity.
Management Philosophies**
- Wisdom Movement: Advocates for resource extraction and economic growth.
- Environmental Movement: Emphasizes protecting ecosystems and biodiversity.
