The prairie serves as the traditional homeland of Native American nations and the land provides for their physical and spiritual well-being.

A. True

B. False

1

What economic activity provides many jobs in the prairie ecosystem?

A. Logging

B. Fishing

C. Hunting

D. Agricultural

1

What animal once roamed freely in the North American prairie?

A. Prairie dog

B. American Bison

C. Coyote

D. Black-footed ferret

2

Use your understanding of ecosystems and the graph to answer the following questions.
How did the bison population change between 1800 and 1900?

A. The population increased

B. The population decreased

C. The population stayed the same

5

Based on the information presented in the graph, what are three ways that human activities may have impacted the bison population? LOOK AT THE GRAPH.

Scientists have identified the bison as a keystone species in the prairie ecosystem.

Review the ecosystem model below that shows some of the interactions of the prairie ecosystem before the bison were removed. Remember that the red lines are positive relationships and the blue lines are negative relationships. For example, if the pronghorn population increases, the coyote population increases. What do you predict happened to the system when the bison were removed?

3

Predict and explain one direct impact on the ecosystem when the bison were removed?

6

Choose two interactions in the model and explain how you think the components changed without the bison. YOU CANNOT USE THE SAME INTERACTION as number 6.

1

Give an example of an abiotic component from the prairie ecosystem.

2

In the graph:
Blue is with Bison.
Red is No Bison.
What do you notice about grass in areas with in and without bison?

A. There is more grass in areas with bison

B. There is more grass in areas without bison

2

Based on the data, scientists predict that the biodiversity of herbivores (animals that eat plants) will be higher when bison are present. What reasoning would explain this prediction? Use data from the model and the graph to support your answer.

1

Bison compete with cattle for food.

True

False

1

What is a priority valued by ranchers (ranchers are people who raise and sell cattle).

B. creating area for bison to roam

C. making money by raising cattle

What could account for the difference in the amount of grass with and without bison?

A. Bison poop fertilizers the grass, leading to more grass in areas with bison

B. Bison eat the grass leading to less grass in areas with bison

C. Bison prevent fires leading to more grass in areas with bison

In the graph:
Blue is with Bison.
Red is No Bison.
What do you notice about other kinds of plants in areas with and without bison?

A. There are more other plants in areas with bison

B. There are more other plants in areas without bison

C. The number of other plants is the same with or without bison

In the graph:
Blue is with Bison.
Red is No Bison.
What could account for the difference in the amount of other plants with and without bison?

A. Bison eat other plants leading to less other plants in areas with bison

B. Other plants are able to grow in areas with bison because there is less grass and competition

C. The amount of other plants is less with bison because of fires

The 30 by 30 law restricts the amount of private land cattle ranchers can have. This limits the number of cattle ranchers can raise. Do you think ranchers support of oppose this part of the plan?

support (like it)

oppose (hate it)

Native Americans have a deep connection to bison. They depend on bison for food, shelter, clothing, tools, and cultural teachings. What is a priority valued by Native Americans?

A. making money off of cattle

B. creating large area for bison to roam

C. creating fences to limit the number of bison in the area

A part of the 30 by 30 plan will remove fences between private and public land. This will allow more space for bison. Do you think Native Americans support or oppose this part of the plan

support it (like it)

oppose it (hate it)

The conservation plan--to buy private land and connect to private and public land--address the priorities of the different interest holder groups. What compromise (trade-offs) will ranchers have to make if the plan moves forward?

A. lose cultural traditions

B. lose grazing land for cattle
