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
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
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
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?

What compromise (trade-offs) will Native Americans have to make if the plan moves forward?
