From November 2010 P2 Resource Booklet Case study: First Nation American Indians and European Settlers 1. Explain why early exploitation of Plains bison by American Indians could be considered sustainable. 2. How did this differ from the approach used by European settlers? 3. Explain three ways in which the status of Plains bison as a natural resource has changed over time. 4. With reference to the map in Figure 6, describe how the range of Plains bison has changed over time. 5. With reference to Figure 4, predict, giving reasons, two impacts that the decline of Plains bison by 1889 might have had on local populations of rabbits. 6. With reference to Figure 8, explain why researchers examined economic and cultural factors as well as ecological factors when they measured the “restoration potential” for Plains bison herds in different locations. 7. Suggest why the Plains bison is sometimes described as an “iconic” (representative, very significant) species. 8. Outline the arguments that might be given for preserving Plains bison as a species by an ecocentric and anthropocentric. 9. With reference to the resource booklet and your own studies, draw a simple systems diagram to show the role that Plains bison play in a grassland soil system.
