Chapter 13 Study Questions

  1. Imagine that you are developing a comprehensive ecosystem management plan for a small lake in an agricultural landscape. How would you define the boundaries of your management plan? What kinds of disciplines and occupations might you engage to help you develop and implement your plan?
  2. The goal of ecosystem management is to maintain the ecological integrity of an ecosystem. But, how would you objectively define “ecological integrity”? How would you know when you had achieved it?
  3. When an ecosystems is used for multiple purposes (e.g., national forest lands in the U.S.) how can ecological consequences of use be balanced with protecting the ecosystem? Consider an ecosystem that is used for timber, fishing, hunting, bird watching, and watershed protection.
  4. Suppose you are a conservation-minded fisheries biologist and you discover that an introduced aquatic invertebrate is enriching the food base for game fish but also causing rapid population declines in some native invertebrates. What argument could you make that might persuade local fishermen to support your plan to eradicate the invader?
