Chapter 8: Soil write any green notes in your notebooks

2 Julia Butterfly Answer the following questions (in your journals) by reading the article about  Julia Butterfly on page 261: 1. What is the difference between clear-cutting and selective-cutting? 2. What happened when Maxxam clearcut redwood forests? 3. How can a “tree sit” prevent widespread deforestation? 4. What did Maxxam ultimately resolve to do? 5. Do citizens of the United States have the right to influence what activities occur on private lands? What if the land is public?  6. Was Julia Butterfly Hill a hero or a villain? 

3 Intro to Chapter 10 p.262: Human land use affects the environment in many ways: Agriculture, housing, recreation, industry, mining, and waste disposal  Resulting in: Deforestation, erosion, species extinctions, soil degradation, climate Values we place on land: food, shelter, and natural resources. Essential Concepts for understanding land use: tragedy of the commons externalities (p.264) maximum sustainable yield

4 Public Lands National Parks- managed for scientific, educational, and recreational use, and sometimes for their beauty or unique landforms. Yellowstone was the first national park –  established by the U.S. Congress, signed by President Ulysses S. Grant on March 1, 1872. Yosemite was designated a national park on October 1, 1890 after John Muir got President Theodore Roosevelt to visit. Managed Resource Protected Areas- managed for the sustained use of biological, mineral, and recreational resources. Habitat/Species Management Areas- actively managed to maintain biological communities. Strict Nature Reserves and Wilderness Areas- established to protect species and ecosystems. Protected Landscapes and Seascapes- nondestructive use of natural resources while allowing for tourism and recreation. National Monuments- set aside to protect unique sites of special natural or cultural interests. Don’t need to write in notebooks

5 Rangelands p.268 Dry, open grasslands that are primarily used for cattle grazing, which is the most common use of land in the United States. (not including CAFOs) The Taylor Grazing Act of 1934 was passed to halt overgrazing.

6 Forests Then Now Areas dominated by trees and other woody vegetation.
Many national forests were originally established to ensure a steady and reliable source of timber.  Then Now

7 Timber Harvest Practices
Clear-cutting- removing all, or almost all the trees in an area. Selective cutting- removing single trees or relatively small numbers of trees from a forest. Ecologically sustainable forestry: An approach to removing trees from forests in ways that do not unduly affect the viability of other trees.

8 Fire Management prescribed burns- a fire is deliberately set under controlled conditions.

9 Federal Regulations National Environmental Policy Act (NEPA)- mandates an environmental assessment of all projects involving federal money or permits. Signed in1969: requires all agencies responsible for a major federal project to file an environmental impact statement-The best way the protect endangered and threatened species is by protecting the habitat. Environmental Impact Statement (EIS)- outlines the scope and purpose of the project. Environmental mitigation plan- outlines how the developer will address concerns raised by the projects impact on the environment.
