UNIT GOAL:  Students shall understand the importance of correct pasture and 
            rangeland management practices for animal health, erosion
            control, pasture production, and maintaining the balance of
            living things within an ecosystem.

UNIT OBJECTIVES:  Upon completion of this unit, students will be able to:

1.  Define the terms common to rangeland management.

2.  List three ways in which overgrazing or poor rangeland management can
    negatively affect the environment.

3.  Calculate, from information provided, the carrying capacity of an
    acreage of rangeland for a species of livestock.

4.  Identify and describe the variety of rangelands found in California.

5.  Collect and label three suitable legumes and discuss factors to consider 
    in their selection for rangeland forage.

6.  Collect, label, and press ten common range plants.

7.  Collect and identify ten weeds and brush common to California rangelands
    and discuss control methods for each.

8.  Identify five plants poisonous to livestock and identify the California
    rangelands in which they may be found.
